ABSTRACT
The concept of smart grid involves the transformation of the electric power grid by the
use of advanced automatic control and communication techniques and other forms of
technological information. The major aim of smart grid is to provide the best quantity of
information and the control of loads for the consumers, grid operators and distributors to reduce
the costs and the system demand while increasing the efficiency of energy. The superconducting
energy storage, compressed storage of energy and pumped hydroelectric all have the importance
as large central technologies for storing energy in smart grid. The smart meter security is the
problem since it is not difficult to gain access physically to the meter device and there is an
instant gain of money from the alteration of the systems.
The integrity of the meter device and the data must be confirmed in the smart grid before
their use. The availability, integrity and confidentiality are very important to this model. The
power system security is a problem because of the likelihood of getting the wrong data
involvement into the model. In the network of communication, the security attacks can be
grouped as a malicious user and the selfish misbehaving user. The selfish misbehaving user
attempt to get more network than the legitimate user by impious the protocol of communication.
The malicious users have no intent to benefit from their own, they obtain the information in the
network illegal. Different communication such a wireless and wired can be utilized to transmit
the data amongst electric utilities and smart meters.

INTRODUCTION
A smartgrid can be defined as a small-scale power grid that can operate independently or
in conjunction with the main electrical grid of the area. Smartgrid is a concept of transforming
the electric power grid by the use of advanced automatic communication and control techniques
as well as other forms of information technology. The system integrates innovative technologies
and tools from distribution, transmission, and generation all the way to the equipment and
appliances of the consumers. The smartgrid concept integrates markets, information, devices,
processes, and infrastructure into a collaborative and coordinated process that enable the
distribution, generation, and consumption of energy in a more efficient and effective way.
Some of the types of microgrids include commercial and industrial microgrids, military
base microgrids, remote off-grid microgrids, and campus institutional or environmental
microgrids. During the operations of the microgrid, the power system that uses electricity, the
generation that is automatic is the system for regulating the output of power of the many
initiators at dissimilar energy plants. Since the smart grid needs the power and load, regular
modifications to the generations from the generators are required. The stability can be known by
determining the regularity of the systems and if it is rising, more electricity is being produced
than used, which causes all the machines in the systems to accelerate.
The smart grid is the concept for the transformation of the electric power grid by the use
of advanced automatic control and communication techniques and other forms of technological
information. It incorporates the advanced technologies and tools from the generation, distribution
and transmission to the consumers' equipment and utilizations. Distribution systems and power
generations are experiencing the new problems leading to the widespread struggles of
investigations in dissimilar ways targeting the increase in the use of renewable and sustainable

Smart Grid 7
energy resources. The traditional smart grid depends on the fossil fuels which offer the power
option for the air emissions and leads to the load shaving peak and climate change while the
electronic smart grid uses the electricity hence reduced the impacts of climate change since there
are no emissions.
The technology of smart grid can support the incorporation of sources of renewable
energy in the future power systems. Its primary goal is to provide the best quantity of
information and the control of loads for the consumers, grid operators and distributors to reduce
the costs and the system demand while increasing the efficiency of energy. The concept of the
smart grid is associated naturally to the creation of the energy by the use of sources of renewable
energy as the smart grid promotes the social benefits like the lower cost of energy, reduced
emissions and larger flexibility to accommodate distributed new renewable energy sources.
These outcomes can be realized by the incorporation of various dissimilar technologies like
information and communication technology for making the demand for energy and creation more
controllable and predictable (Amin, 2005).
For 100 years and above, there has been no improvement on the simple electrical power
grid structure. To solve the complications of the prevailing power grid, a new idea of the smart
grid arose. Among the deficiency of the electrical power grid over the smart grid is the lack of
the computerized analysis, poor reflectiveness, lack of the awareness, the mechanical switches
causing the slow time responses. These have caused the blackouts for over forty years. Some of
the additional inhibitors are the high demographic growth and the request for energy, the failures
of equipment, climate change, problems of energy storage and reduction in fossil fuels. Also, the
emissions of greenhouse gases on environment have been a problem that is caused by the

Smart Grid 8
transportation and electricity. Therefore, the new grid was required to solve all these problems
and to recognize the abilities the smart grid emerged (Amin, 2005).
THE LITERATURE REVIEW OF THE SMART GRID
The smart grid is an improvement of the existing electrical power grid. The advancement is in
the reaction to varying the necessities of the consumers. Numerous safety of cyber is presented in
the smart grid. In this section of literature reviews, storage systems, operation, cybersecurity are
discussed (Amin, 2005).
Characteristics of smart grid
The smart grid have a property of self-healing; it can adjust and redirect the electricity flow in
the time that the path of electrical transmission is disturbed. This is carried out by the self-
assessment of the power system state which is continuous hence major blackouts and their
frequencies can be reduced. When the number of the blackouts are reduced the economic losses
are also reduced (Bazzaco, 2010).
The smart grid includes and motivates customers; there is slight interface among the suppliers
and customers in the electrical power system. Smart grid gives the customer with more opinions
and information about their electrical power hence will enable the consumers to make a good
decision about their use of power that saves their money and promotes the competition amongst
suppliers of power. This happens by allowing the communication of two way between the
suppliers and customers. The smart grid also can cooperate with the electrical applications in the
home of the customer which allows the appliances to plan their runtime when the power is at its
lowest price (Crovella, 2003).

Smart Grid 9
The smart grid is resilient to natural disaster and attacks; the smart grid is resistant to physical
outbreaks and cyber-attacks. The power grid is the critical tool and damaging it can have
dangerous effects on the welfare of the society.
The smart grid provides an increase in the quality of the electrical power; the electricity is
needed to be available every time from the power grid and also retain an endless voltage. Some
of the procedures of manufacturing are very delicate to the deviations of voltages. A dip in the
voltage can have the same problems as power loss on the industrial processes. These voltage
fluctuations can cause the loss of productivity (Divan, 2006).
The smart grid accommodates all the storage and generation choices available; the
incorporation of the renewable resources into the power grid has many implications. The present
power grid is the model of transmission premeditated to permit the flow of electricity of one way
to the consumers from single source of generation. The renewable sources of energy are
normally disconnected from the traditional power sources geographically, and when they are
combined into power grid it distributes sources of power. Subsequently the power grid was made
for the one source of power and not many different sources of power, this results to the
implications. The smart grid is able to support both new and traditional power sources (Godfrey,
2004).
The smart grid enables the electrical markets; the markets of electricity in the smart grid
enable competition between the dealers of the power. This competition will enable the providers
of the power to produce an efficient and cheap means of generating power. This lowers the
charges of electrical generating of power for the consumers as dealers compete for the
businesses. The smart grid also supports the disseminated sources of power, and this allows the
new power supplies and provides of the electrical services to enter the electrical markets. The

Smart Grid 10
electrical markets transmit present prices of electricity based on the model of the supply demand.
Electricity will be cheaper when there is surplus and expensive when the demand is high. The
consumers can use the data to program the tasks that use more power when it’s cheaper (Grob,
2008).
Smart grid optimizes assets and operates effectively; the feature that makes the grid a self-
healing can be used for the managing the assets. The smart grid have the ability to evaluate the
conditions of apparatus automatically and manage the configurations of the equipment. The
automation management can be done at a lesser cost as linked to the physical management. The
management and mechanization of the apparatus can also lower the failure of the apparatus since
their deprivation can be traced. The smart grid also incorporates the technologies and new
innovations that reduce the loss of energy when reporting the electricity. This decrease in the loss
of energy will upsurge the efficiency of the power grid by removing the extra wastes of power
(Kanabar, 2009).
METHODOLOGY
Components of the smart grid
The smart meter; the smart meter is an electronic device for measurement installed by the utility
to enhance the communication of two way between the utility and the consumers and also
manage the electrical systems of the consumers. The meter is able to communicate the real-time
energy consumption of the electrical system in the short interval of time to the utility connected.
In the electromechanical meters, the cumulative numbers of the units for electricity is recorded
end month and the smart reader is connected to the utility which transmits the usage of electricity
on the real-time basis. Smart meter facilitates the real-time pricing, recording of the electricity
consumption that is automatic and a complete error eradication because of the manual readings

Smart Grid 11
and reduce the cost of labour and enable the designing the fault detection instantly (Kocak,
2011).
Advantages of the smart meter;
 Accuracy in the reading of the meter; in the case of the electronic meter, the reading of
the meter have to be read by the utility representative. The smart meter transmits the
readings automatically to the utility connected.
 Recording of data; the conventional meters record only the consumption of electricity in
the system, time and pattern of the consumption of electricity and when and how the
electricity is used. They usually record the real data corresponding to the consumption of
electricity.
 The tracking of real-time; consumers can go online and check their usage of the
electricity and make changes in their pattern of consumption so that they can consume
accordingly. The smart meter gives efficient control to the consumers over their usage.
 detection of the automatic outage; the person owning the conventional meter should call
the utility whenever there is an outage of power while with a smart meter, there is the
detection of the outage automatically as they are with the electric grid constantly.
Better services; the smart meters are connected directly to the utility and becomes very simple to
disconnect and connect to the power for a house, this saves the needs of a technician going in
person to disconnect and connect the supply (Momoh, 2009)
Advanced metering infrastructure
The advanced metering infrastructure is the convergence of the grid, communication
infrastructure, and the infrastructure for supporting the information. The network and centric

Smart Grid 12
with lack of the composite across the industry are the motivations for its developments. The
problem to be addressed by the advance meeting infrastructure are normally new to the industry
of utility but the procedures for implementing the large scale, solutions of network-centric with
the high information assurance. The telecom, defense and cable industries can give more
examples of the requirements and standard that are applicable to its implementation (Morrow,
2010).
Advantages of advanced metering infrastructure;
 Market applications; it serves to reduce the transportation, labour, and the cost of
infrastructure associated with the reading of the meter and maintenance.
 Application to customers; it serves to increase the awareness to the customers about the
reduction of the load, reduction of the bad debts, improving the flow of cash and enhance
the satisfaction and convenience of the customers to provide the load management and
demand response for the system performance and reliability.
 distribution operations; curtails the load of the customers for the management of the grid,
optimize the network based on the collected data, allow for the outages locations, and the
services restoration, improves the satisfaction of the customers with the reduced duration
of the outage and optimization of the distributed systems and generation management and
gives the responses to the emergency demand.
 Control and monitoring extend the net to the delivery of pole-top transformers and to
consumers by the use of advanced metering infrastructure. More granular data field will
improve the efficiency and gives the data for other applications of the smart grids like the
management of outages. Advanced metering infrastructure enables the utilities to meet
the collection of the meter data, participation in the responses demands, and support the

Smart Grid 13
tools evolution that will derive the future of the smart grid including the integration of
distributed generations and electric vehicles (Piccolo, 2010).
Phasor management unit
Phasor management unit is the electronic strategies that use the digital component for
handling the signals to measure the AC waveforms transmit them to phasor according to the
frequency of the systems and coordinate the sizes under the control of the GPS sources of
references. The analogues signals are processed and sampled by the logarithm recursive phasor
to produce the current and voltage phasor. The different parts of the phasor measurement unit are
shown below;
Figure 1: The components of the phasor measurement unit (Grob, 2008)
The phasor network comprises the phasor measurement unit, dispersed through the
system of electricity, phasor concentrators of data to the information collectors and data
acquisition and supervisory control system at the facility of central control. From the samples of
voltage and currents, the angle of magnitude and phase of the current and voltage signals are
calculated in the microprocessor of the phasor measurement unit. As the phasor measurement

Smart Grid 14
unit uses the signals of the clock of the global positioning system to give the synchronized
positions and the synchrophasors are normally the measured phasors (Piccolo, 2010).
The data from the dissimilar phasor measurement unit is dispersed in the grid is
transported to the concentrator of the data phasor situated at the center of the control. The
concentrator of data phase sorts and collects the data by the time brand until the time of the
arrival of the least data. The intense data by the PDC is used for dissimilar applications at the
center of control. The collected data from many PDC supplied over a given area is passed to the
super PDC. A PDC collects the data phasor from many phasor measurement units and aligns the
data by the tag of time to create the data set that is synchronized and passed the data to the
applications processors.
For the applications that process the phasor measurement unit data across the grid, it is
important that the measurements are aligned with time-based on their original time tag to create
wide conditions for the system. The phasor measurement units usually use the line of phones to
connect to PDC which send the data to wide area measurement system server. They also use the
network of mobiles to transfer the data which enables the potential savings in the deployment
cost and infrastructure at the expense latency of reporting the large data. The technology of
phasor measurement can be used for improving the security through the synchronized
encryptions like the sensing trusted base (Radosavac, 2011).
Substation automation
The smart grid promises the best way of consuming and supplying the power. The smart
grid is the data communication network intergraded with a power grid that enables the operators
of power to analyze the collected information about the transmission, generation, and
consumption. To achieve all these visions of the smart grid, the transformation of the

Smart Grid 15
infrastructure of the power grid communication is required in the transmission and distribution
stations. While the modern data for communication has evolved with the modems of telephony
to the IP network, many utilities of the power are deploying the access of modem and the
technology of the serial bus to communicate with their substations. The existing SCADA
systems located in the substation cannot evolve and scale to support the intelligence of next
generation. Since the Ethernet switches and the IP routes have become available widely, many
utilities are ready to transform their communication network to the IP based on the serial-based
communication.
Figure 2: The substation automation (Kocak, 2011).

Smart Grid 16
Substation automation enables the part of the end to end security and allows the operators
of the network to control the network devices, users and traffic. The physical security can be
added on top of this security network to create the zones of security to access the control, IP
cameras for monitoring and the analytics of videos to alert and protect the network
administrators of the intruders. Substation automation can enable the technology for load shaving
and demand response which reduce the need for building many plants to meet the demand peak
(Smith, 2009).
Traditionally, the substation automation has been focused on the automation functions
such as controlling, monitoring, and collecting the data within the substation. This scope allows
for the control of the automatic machines in the fence substation but doesn't take advantage of
the automated feeder devices. The substation automation is expected to expand with the
increased control of capacitor banks, relays, and the voltage regulators. Substation automation
should play the expanded role in the operation of the grid.
Advanced control methods
Advanced control technologies are the devices that diagnose, analyze, and predict the condition
of the modern grid and determine the best corrective measures to prevent, eliminate and mitigate
the outages and the power quality disturbances. These methods give the control transition and
level of the customer to manage the reactive and real power across the boundaries of states
(Momoh, 2009).
Current states
The communication infrastructure supporting the control systems of today comprise of the wide
technologies that are patched together. The required information is passed from the sensor to the

Smart Grid 17
control system and processed by the control system and passed to the devices for controlling.
This current communication infrastructure is limited to support the requirements of high speed
and broad coverage required by the advanced controlled technologies. It does not give the
networked it's important for the modern growth of the smart grid. The today's grid lack many of
the smart sensors and the devices for control comprising the portal device for the consumer that
should be deployed measure the needed data and give the control mechanisms to manage the
electric systems (Morrow, 2010).
The progress being made; distribution automation technologies are being integrated currently
with the data acquisition and supervisory control systems to give the fast reconfiguration of the
specific sections of the distributed systems. This will reduce the impact of the system failure and
faults and the disturbances of power quality on the customers. The distribution automation gives
the ability to operate and monitor the devices that are constructed throughout the systems for
distribution thereby optimizing the reactive supply, station loading, and outages identification
and monitoring the health equipment. This operation should happen on the wider scale and
quickly (Morrow, 2010).
Some of the today's technologies are based locally, like the substation, where the
important data can be collected in the near real-time without the need of the wide communication
infrastructure. The algorithms of control act autonomously at the local substation and are
integrates with some systems at the central to enable others not situated at the substation to have
the data access. The technologies of the substation automation provide the functionality and are
about to be implemented at most of the utilities.
Significant advances have been made in the algorithms of the control software in every
industry and more has been done in the area of the advanced control technologies. Some of the

Smart Grid 18
technologies for the modern smart grid are available currently or are in the development and
research. These technologies are being integrated slowly into the three important areas:
analytical tools. Distributed intelligent agents and operational applications. They are discussed
as follows (Morrow, 2010).
Distributed intelligent agents
They are adaptive, self-healing, self-aware and semi-autonomous systems of control that rapidly
respond at the local level to the human operator and unburden centralized control system. Most
of these agents are normally combined with the peer to peer communication to form the system
of multi-agent. These systems of multi-agents can reach the objectives that are challenging to
attain by the specific systems. Some of the technologies and described below;
Digital protective relay; this can sense the electricity systems parameters, data analysis and
initiate the control actions of data to protect the system's assets. The protection coordination can
be updated automatically as the circuits are reconfigured and give the post-disturbance data for
the event of analysis. The enhanced coordination makes sure that only last device feeding a
faulted section clears the fault (Piccolo, 2010).
Intelligent cap charger; it senses both the low and high voltage sides to do the advanced control.
Also, it minimizes the draw of the reactive power from the transmission system.
The tool of rating circuits; determines the accurate and safe rating of the lines and normally gives
the additional capacity of lines except when the conditions of weather and loading of lines are
not favourably.

Smart Grid 19
The system of managing energy; this monitors the parameters of the electric systems and
marketing information. It considers the presets of the consumers and act on their behalf to
manage the cost of energy health and comfort.
Grid-friendly appliance controller; this senses the conditions of the smart grid by monitoring the
voltages and frequencies of the systems and gives the automatic DR at the time of the systems
distress and faults. Supports the programs of the demand response based on the pricing of the
real time.
Control devices for the distributed power; this decreases and increases the impendence of the
lines, improves the utilization of the lines that under-utilized. They can manage the systems of
flexible alternating current transmission situated at the substation to provide the control of the
voltages and line flow (Piccolo, 2010).
Analytical tools
System performance; it monitors the congestion, frequency and voltages to detect the abnormal
patterns of operation. It also predicts how the systems will respond if some of the equipment are
forced out of the service and validates the data of real-time and models of offline systems.
Phasor management analysis; detect the grid emergencies, supports more estimation of the
states, improve the modelling and analysis of the dynamics to determines if the transient swing in
the system of power is unstable or stable (Radosavac, 2011).
Market system simulation; analyses the aspects of market and engineering of the smart grid and
provides the open source environment where the software components developed independently
can be shared by other organization and the individual,

Smart Grid 20
Distribution location of the fault; data from the digital relays will be used along with the circuit
database to determine the location of the faults on the distribution circuits.
Operational application
The modern smart grid will rely on the automation, intelligence, and the decentralized control for
the selected applications especially those with the primary local impact.
Substation automation; provides the remote control, local control and monitor and substation
levels. It makes the information at the substation available for the retrieval by the planners of the
substation, protection engineers and personnel for the maintenance. The IEDs and the local
network are linked to many users to set the foundations for the function of the high-level remotes
like the management of power system and monitoring the condition of the equipment when it is
in the service.
Distributed automation; the IEDs have been integrated with the systems of the SCADA to give
the fast reconfiguration to reduce the impact of the systems form stressor faults and other
disturbances of the power quality.
Asset optimization; integrates the operation of the plant, management of fuel, and the process of
maintenance. It collects analyze and verify the data of operation using the specific parameters to
the facility and informs the operator in the real time when the systems if running below the
expectation. It identifies the conditions that can cause problems and determine the major cause
and prioritize the recommended actions to be taken or solutions (Radosavac, 2011).

Smart Grid 21
THE FUTURE STATE OF SMART GRIDS
The advanced control method of the future need the integrated and advanced systems of
communication to operate effectively. In the future, the advanced control systems will be
sophisticated and will consider the national and regional perspective and will fully deploy the
local ones throughout the national grid (Radosavac, 2011).
Functions that the advanced control methods will perform in the
future;
Collect data and monitor the components of the grid; in the future, the low-cost transformers will
measure the parameters of consumers and the systems. They will provide the conditions of the
components of the smart grid and will be deployed and integrated with the ACM to give the
assessment of the condition of the systems. The phasor measurement unit integrated with the
GPS will be deployed to provide the status of the gird and the warning of the developing
instabilities nationwide.
Diagnose and solve; the availability of the data of near real-time processed by computers of high
speed will enable the experts to identify the solution for the emerging, existing, and the problems
at the system. Then success probability for every solution will be identified and results made
available at the human operator (Smith, 2009).
Take the autonomous actions when appropriate; the protective relaying schemes have acted
independently in the response to the fault of the system for many years and will still continue to
do the same. The modern smart grid will make important advances by incorporating the
communication system of real-time with the advanced analytical technologies. These advances
will make the possible actions for the detected problems and prevent the emergent problems.

Smart Grid 22
Provide the information for the human operator; the ACM will give the information to the human
operator apart from giving the actual signals to the control devices. The vast amount of collected
data by the control systems is of the great value to the human operator. The data collected will be
filtered and presented to the programs to create the effective interface of man-machine. The data
will also give the assistance of decision. When the algorithms of control determine the actions
correction needed to be made by the human operator, it will give the option to operator, and
success probability for every option (Smith, 2009)
OPERATION OF THE SMART GRID
Operation reserve
Depending on the infrastructure of communication that are available and the agreement
amid the DR aggregator and customer there must be many resolutions to simplify the inhabited
DR to contribute in the operation reserve services. The available solution for the new applicants
giving the services is used to broadband the router and internet. The communication amongst the
supplier of the electricity and the central server is met by the subscriber line of digital
asymmetric. Through the infrastructure, the dealer is stating the responses ahead of the real time.
If the central server decided that fallback is required from the dealer then it will issue the reserve
instructions. For example, fifteen minutes ahead of the real time when the decrease of the
demand is required, at the reception of the reserve order, the provider will raise the cost of
electricity starting from the interval of fifteen minutes for the time stated by the central server
(Divan, 2006).
The price increase is delivered by the smart metering communication infrastructure
which comprises wide area network. The smart applications linked to the hub get the cost
increase and will interrupt their cycle. Hence the reduction in the combined consumption is met.

Smart Grid 23
Figure 3: The operating reserve of the smart grid (Thomas, 2010)
Automatic generation
In the power system that uses electricity, the generation that is automatic is the system for
regulating the output of power of the many initiators at dissimilar energy plants. Since the smart
grid needs the power and load, regular modifications to the generations from the generators are
required. The stability can be known by determining the regularity of the systems and if it is
rising, more electricity is being produced than used, which causes all the machines in the systems
to accelerate. If the regularity of the system is decreasing, it means that there is more burden on
the system than the prompt generation can give which causes all the generators to slow down
(Godfrey, 2004).
Turbo governed control is the type of automatic generation. It has the stored energy of
kinetic because of the large rotating masses. All the stored kinetic energy in the power system in
the rotating masses is the part of the grid inertia. When loads of the system increase, the inertia
grid is used to supply the load and leads to the reduction of the stored kinetic energy. Since the

Smart Grid 24
power of mechanical of the turbines associates with the power that is delivered, the generators of
turbines have the decrease in the angular speed that is proportional directly to the reduction in the
frequency in synchronous generators (Grob, 2008).
Control and automation of a smart grid
The advanced integration of the sensing, telecommunication, optimization and control
have been kown to help to achieve the self-healing, interaction, reliability and efficiency of the
smart grid.
Figure 4: The smart grid automation functions (Thomas, 2010)
The figure above shows the major elements that should be considered in the design of the
smart grid. System of power control depends on the quality of the sensor measurement and
accessibility. Faults caused by the bad or broken connections, failure of the sensor and bad
communications may cause the letdown of the controllers of the power systems and leads to
severe contingencies. The technologies that tolerate faults is needed in the smart grid to advance
its security, advanced methods and reliability of control should meet the real time by using the

Smart Grid 25
methods of intellect computations. These processes give the uses like gathering and monitoring
of the data from the sensor and analyze data to identify and gives resolutions (Thomas, 2010).
Intellect in the smart grid is needed in every level, it is needed to provide every substation
and the power company with the CPU that communicates and monitor with others through the
smart sensors. The needed data of real-time needed by large geographical area observing and
controls systems will be given by the smart sensor and sent back to the main controller system
that should be accurate and faster than the data acquisition and supervisory control of tradition.
The increasing nonlinear and complexity, the future and nature smart grid will need accurate and
fast online monitoring systems like control systems that are effective, wide-area controller for
adaption and wide area monitor. The wide area controllers’ acts as the controllers’ of the globe to
coordinates the actions of the local controllers comprising those on wide firms. Every local
controller connects the wide area controller and receives the signals thus improving the
performance and dynamics of the system (Thomas, 2010).
Control methods for the smart grid with distributed generations and renewable energy sources
Due to the increasing demand for energy and the move toward the production of clean
energy, distributed generations based on the renewable energy sources had a high growth in the
last decades. Photovoltaic, wind turbines, and the combined power and heat systems are installed
at dissimilar levels in the systems that distribute power. The photovoltaic power plant normally
operates on the extreme power point making the power available from the panels while the
performance of the storage unit is controlled by the prices of energy. The output power from the
storage devices can be controlled by the supervisory central controller for meeting some of the
requirements in the smart grid. The controller of supervisory should take good care of the

Smart Grid 26
optimal power flow, the grids optimization and should letter the generated energy by the
distributed generations based on the limitations of the networks (Thomas, 2010).
Wind turbines have many control options of the remote with the concern to the control of
dynamic energy such as the power limiter control, maximum power control, balance control and
Delta control. For the secure, reliable and efficient operation of the smart grids, the devices of
controlling the voltages needs be fitted at the dissimilar parts of the systems. The distributed
generations should participate fully in the control of the voltage which is not synchronized still,
and this character will be highly significant for the execution of the smart grid.
FAULTS AND CHALLENGES OF THE SMART GRID
 Actions of self-healing
 A smart grid must be able to self-heal. The grid should have the ability to take actions to
produce the power continuously after the emergency happened. The microcontroller has
to be linked with all the asset of the grid-tied over the consistent system of
communication connected to the center of the central commander. The following are the
faults facing the structure;
 Safety; when the smart grid is connected with the computers it get involved in the
available attacks of the internets like worms, spams and viruses. Also, the grid which
represents the target of nations should be made secured against the attack but when
computerized it becomes accessible to the attack by the hackers (Wang, 2010).
 consistency; the grid’s operation when the communication networks take care which
normally fails when required in case of the fire, storm and lightning. Renewable energies

Smart Grid 27
 This is active in the research area, the renewable energies like winds or the solar when
integrated with the grid experiences many challenges like;
 Wind forecast; for the generation profile to be predicted over a period of time, the wind
speed and direction should be predicted and computer the power generated by the wind.
It is difficult to have the accurate estimate of wind because the wind is the intermittent of
nature.
 Dispatch of generated wind; the operation of the systems that generate the wind power
can be known as the dependent of weather and this will influence the dispatch of the
generation.
 Optimization of power flow; the generation of wind exist in the sites where the wind is
blown and the sites could be in dissimilar locations from where the load is. The main
challenge is the congestion on the lines of transmission. Since construction new lines are
economically feasible then transmitting the power to dissimilar places over the long
distance represent a severe problem (Wang, 2010). Energy storage systems
 When depending on the renewable sources of energy for the production of power, it's
good to consider the storage systems for the energy. The challenges that affect the
energy storage are;
 Cost; the systems of storing energy are expensive. , more investigation should be done to
lower the price of using the systems of the energy storage for the smart grid. The addition
of the systems for storing the energy is followed by the study of the power systems.
Every system of storing energy have to be made for the network point being joined. This
increase the cost more (Wang, 2010).

Smart Grid 28
 Non-flexibility; the energy storage system for the smart grid need a lot of materials and
studies which are usually expensive. Every system of storing the energy is made for the
specific configuration of the network and it's not easy to adapt to the network changes.
The systems of storing energy are usually aimed for a specific system therefore they are
not flexible. With the power grid in the future, it becomes useful to seek upcoming ways
to make this equipment adaptable and flexible to the many systems. Impulse consumption
 The role of the smart grid is to inspire the consumers to take part in the management of
energy of the smart grid. These functions are influenced by two major challenges;
 Privacy; customers require to interconnect with the utilities to participate in the
management of the consumption of power. This shows the data sharing amount between
the two entities. The utility can access the private information of the consumers since the
smart meter normally collects the data and sends them to the utility.
 Security; a collection of data is done by the wireless machine. Data can be intercepted
and ruined by the bad persons and can damage utility and consumer. This matter has an
important influence on the utility because the consumers are able to sell and generate
energy to the grid. Corruption of data can drive a rise in the cost to the company (Wang,
2010).
Storage system for the smart grid
Of the types of the technologies of storing energy that could support the smart grid, the
batteries that are advanced may give the best potential. The superconducting energy storage,
compressed storage of energy and pumped hydroelectric all have the importance as large central
technologies for storing energy. The advance s in the electronic power that converts the DC to

Smart Grid 29
AC power have really helped the systems of soring battery more reliable (Amin, 2005). There
are four types of the advanced batteries that help in the energy storage for the smart grid;
Sodium sulfur battery; this battery operates at 300degrees Celsius using the reaction of an
electrochemical between the sulfur and sodium. The negatively charged electrode with molten
sodium and the positively charged electrode with molten sulfur are divided by the electrolyte of
beta alumina. The electrolytes allow the positive ions of sodium to pass and mix with sulfur to
form a sodium polysulfide, during the release, the ions of sodium in the electrode that is negative
pass through the electrolyte to reach the sulfur in the positive electrode. The battery cannot be
given time to cool because the sulfur and sodium will damage the battery when solidifies. The
backup generators must be installed the make the battery hot even a major outage on the smart
grid. The batteries are sealed to keep them from the moisture which could make the sodium to
burn. Every cell is enclosed nu the steel to protect the sodium polysulfide form corrosion.
vanadium batteries; the vanadium is a type of battery that uses the electrolyte of the liquid
vanadium stored in the external tanks that flows in the power cell that regenerates producing the
electric power through the process of electrochemical. The benefit of the vanadium battery is that
more power can be stored by enlarging the tank of the electrolyte. The power rating is the work
of the regenerative cells inverter and fuel. The batteries have a low internal discharge rate and
losses caused by parasites (Bazzaco, 2010).
zinc bromide battery; in this type of the battery, electrolyte is pushed from the two tanks of the
electrolyte through the block of the battery in two circuits, one for the cathode cells and the other
for the anode cells. The electrolyte in the circlet of the anode is the analyte and the electrolyte in
the loop of the cathode is the catholyte. The catholyte and anolyte are in the contact through the
separators of micro-porous cells. The components of ions in the electrolyte can pass through the

Smart Grid 30
separator of cells readily and the mixing of the catholyte and anolyte is prevented. The system is
present that consist the storage of energy. System control, conditioning of power, and
management of heat that can be placed for the immediately dispatchable storage of energy
(Bazzaco, 2010).
Lithium-ion battery; the cathode here is lithium oxide of metals and carbon is for the anode. The
electrolyte is made of the salts of lithium softened in the organic carbonated. when the battery is
charged, the atoms of lithium in the cathode becomes the ions and moves to the carbon anode
through the electrolyte where they mix with the electrons externally and left between layers of
carbon as atoms of lithium. This procedure is usually reversed when discharged.
Capacitors; they store the electric energy is the charge of electrostatic. The cumulative array of
the bigger capacitors have the best characteristic that makes them good for the energy storage of
smart grid. They store more quantity of electric energy than the unoriginal capacitors. They are
normally made and discharged more quickly, to give the required quantity of energy over the
small duration of time.
Compressed air energy storage; this involves the compressing the air by the use of energy that is
not expensive so that the air compressed can be utilized in the electricity generation in case the
energy is sufficient. To change the stored energy to electric energy, the air compressed is moved
into the system of turbine generator. As the air is produced, it got heated and transferred through
the turbine of the system and as the turbine spins it turns the generator to produce the energy.
This energy is stored in the tank or the large pipes to be used by the smart grid (Crovella, 2003).
Flywheels energy storage; the flywheel systems of energy storage include the cylinder with the
shaft that spins faster within the enclosed robust. The cylinder is levitated by the magnet hence

Smart Grid 31
limiting loses and wear that might be caused by the friction. The shaft is connected to the
generator or the motor. The electric energy is changed to kinetic energy by the generator or
motor. The kinetic energy is stored by the increasing speed of the rotation of the flywheels. The
kinetic energy which is stored is changed to the electric energy through the generator or the
motor slowing the speed of the rotational flywheels.
hydroelectric; the key basics of the pumped system of hydroelectric are the generator or turbine
apparatus, upper reservoirs, a waterway and the lower reservoirs. The turbine is same equipment
used for the ordinary hydroelectric power companies that don't incorporate the energy. The
pumped system of hydroelectric power store energy by the operation of the turbine in reserve to
propel the water into the vessels uphill when the cheap power is not available. The water is
produced when the power has value and when it is generated, it move through the turbine and
turns the generator to generate the electric power (Crovella, 2003).
Semiconducting magnet energy storage; the medium of storage of the superconducting magnet
system for the energy storage comprises of the coil made of the materials of superconducting.
The additional components include the equipment of power conditioning and the refrigeration
system that is cryogenically cooled. The coil is ventilated and cool to a temperature below the
needed temperature for superconductivity. The power is stored in the field of the magnets created
by the direct flow of the currents in the coil. Once the power is stored, the current cannot be
damage, so the energy is stored indeterminately.
Thermal storage of energy; there are many ways of storing the thermal energy for the smart grid.
the common way that is usually used involves the making ices when the prices of energy are low
so the stored cold ones can be used in the reduction of the cooling needs, especially the cooling
compressor when the energy is not affordable (Crovella, 2003)

Smart Grid 32
Cyber security of the smart grid
Components of smart grid
PCs security; the systems of controlling processes can be applied by the smart grid to control as
well as monitor the parts of the electric power grid physically. The conventional process control
systems are made to perform in the secluded environment that lacks the outside network
connections, they normally lack the security built in. this is the matter of the smart grid because
they monitor a large area of the power grid, to mean that there are several points of entry to the
network. The process control systems used in the smart grid ensure that these matters of
securities are addressed. There are many types of the process control systems and the regularly
used in the power grid is the acquisition of data and supervisory control systems (SCADAs).
When the computer is cooperated, only the computer data is cooperated and in some cases, some
of the computer hardware may be destroyed (Divan, 2006).

Smart Grid 33
Figure 5: The process control system intrusion detection systems (Divan, 2006)
Smart meter security; the grid is also the group of the smart grid security research security, they
are the devices installed at the site if the customers, and are utilized in measuring the quantity of
the utilized power. The smart security are in electrical form of the currents meters of power that
are presently used. The reading of power is returned to the dealers of the power at the fixed
frequencies. These types of meters are not just utilized when determining the used power by the
consumer, as well as in providing the smart grid a mechanism of feedback that may be applied in
modelling the requirement of power use at an extra comprehensive level than what is available
presently.
The safety of the smart meter is very significant since when the reading is altered from the
device can cause the inaccurate billing and wrong approximations of power usage. Alteration of
the smart meter can give the attackers with the gain of money and since the device is designed at
the site of the customers, the device can be accessed easily. The smart meter readings should be
correct, confidential and not modified. Tools have been built already to profile the reading of the
electric power usage to determine the type of the domestic appliances that are being used. This
information can be useful to many individuals and companies and is a private apprehension. The
accessibility of the smart meters is flexible than other components of the smart grid (Godfrey,
2004).
The smart meter security is the problem since it is not difficult to gain access physically to the
meter device and there is an instant gain of money from the alteration of the systems. The
integrity of the meter device and the data must be confirmed in the smart grid earlier before
usage. Privacy of the smart meter reading is another a problem. They should be networked to the
dealers of power for better performance of functions.

Smart Grid 34
Figure 6: The smart meter redundant meter reading of the smart grid (Godfrey, 2004)
Figure 7: The smart meter intrusion detection system (Grob, 2008)
Power system state estimation security; the smart grid is able to regulate the characteristics of the
power systems. This normally takes place to ensure stability in the power grid. The grid is
expected to model correctly the condition of power system to make the good assessments as well
as take actions on them. These model of estimations makes parts of the process control systems.
The safety of the state of the power systems approximation model is significant since it is
utilized by the smart grid in maintaining the electrical power system. The state of power systems
approximation model is the tool that the grid process control system used to model the agent data

Smart Grid 35
and the sensor. This means that the securities that are important in the process control systems
are also important to this model (Kanabar, 2009).
The availability, integrity and confidentiality are very important to this model. The power system
security is a problem because of the likelihood of getting the wrong data involvement into the
model. Financial gain and stability of the system are the motivations for their attackers. Many
process control systems have the issue of false data injections and distinguishing between the
false and actual data is a challenge. There are many devices that that can separate wrong data
from normal data but they are not efficient gains the attack of false data.
Smart grid communication security protocol; this smart grid depends on the protocol of
communication between different components for them to function and every constituent has
dissimilar requirement of communication. The necessities of communication vary to high data
from low latency and every component has a given security requirement. The smart grid requires
many protocols of communications to meet the requirements of the varying connections. The
safety of the grid protocol of communication is significant since the communication network is
the strength of the smart grid. Numerous of the functionalities of the smart grid cannot occur
minus the communication process (Kocak, 2011).
The aims of security are significant depending on the type of apparatuses that are
communicating and the amount and type of data they exchange. The grid communication
security protocol is a problem since there are several communicating constituents each with their
own requirements of communication. The technology of the smart grid requires integration with
the legacy systems of power, and many of these devices have constraints that must be put into
considerations. The devices of legacy can introduce the vulnerability of security typically to the

Smart Grid 36
system because of the lack of security support. A feature of the smart grid communication
networks;
 Performance metric; the simple work of the internet is to give the services of the data like
downloading of music and web surfing. The great importance of the internet designs is to
achieve high data and fairness among the consumers. Power communications are used to
ensure secure, and reliable real delivery of the messages and non-real time management
and monitoring.
 Traffic models and time requirements; many internets traffic flows have the similarities
like the World Wide Web. In the network of the power, more of the traffic is periodic for
the purpose of the monitoring which is consistency, like the sampling of raw data in the
substations of [power and periodic reading of meter in the networks of home area. over
the internets, most of the traffic is best effort ones while traffics of delay sensitive has the
requirements for the delay to support the multimedia services. another feature of the
communication protocol is the protocol stack and the communication model (Kocak,
2011).
Smart grid simulation for security analysis; testing the design of the grid or changes might be
very difficult. The system of power might be available every time so taking it down to do tests is
impossible. It is possible to model the smart grid in hardware and software and can be used to
investigate the safety and other aspects of the grid. The simulation of the smart grid is important
because of the smart grid testing issues. Building and modifying the large-scale smart grid for
every test is not practical, it is not easy to use any system of power when operating to test since
the tests cannot compromise the availability of the system. The smart grid simulation is the
problem since the smart grid is the complex and large system. Most of the components of the

Smart Grid 37
grid are linked together and any slight changes in the constituent may cause the effects to other
components in the system. The components might also have a solitary functionality in the system
of power, but its implementation may be different at various installations (Kocak, 2011).
Figure 8: The smart grid simulation model for security analysis (Momoh, 2009)
Integrity, availability and the confidentiality are the main objectives of cyber security. The
following are the cyber security necessities for the grid; attack the operations and detection
resilient, compared with the systems of the legacy power, the properties of the smart grid an open
network of communication over the topographical areas. It is possible to make sure that all the
nodes in the smart grid to be safe to the attack of the network. The communication network is
required to do the testing, profiling consistently and compare to monitor the traffic status of the
network to identify and detect the irregular occurrences because of the attack. The network must
be self-healing to continue the operation of the network in the act of attack. Because of the

Smart Grid 38
significance of the energy infrastructures, operation in the communication network is beneficial
to sustain the obtainability of network in the smart grid (Momoh, 2009).
The smart grid infrastructure network integrates many users and electronic devices.
Documentation is the process of the verification of the identity of the user or device as the
prerequisite for giving them contact to the resources in the system’s information of the smart
grid. The effort of accessing the control is to make sure that resource are accessed by the
authorized person that is identified properly. Strict control access must be forced to prevent those
who are not authorized from retrieving the confidential information and controlling important
infrastructure. To meet the desires, the nodes in the smart grid must have the cryptographic to do
the data authentication and encryption (Morrow, 2010).
Secure the communication protocol; differing from the network of conventions, delivery of the
message.
Cyber security threats in the smart grid
As the safety problems majorly come from the hateful attack of the cyber through the networks
for communication, it is important to recognize the weaknesses in the smart grid under the attack
of the network. In this section, the overview of the cyber-attack is given towards the smart grid.
Attack classification
In the network of communication, the security attacks can be grouped as a malicious user and the
selfish misbehaving user. The selfish misbehaving user attempt to get more network than the
legitimate user by impious the protocol of communication. The malicious users have no intent to
benefit from their own, they obtain the information in the network illegal. The malicious
behaviour is more concerned than the self-misbehaving in the smart grid because many devices

Smart Grid 39
for computations are used monitoring and controlling the purposes than providing the services of
data like sharing and downloading. The malicious attack may bring the damages to the supply of
power and power outage which are forbidden in the smart grid. The malicious attacks ate based
on the smart safety purposes that are integrity, confidentiality and availability (Morrow, 2010).
Attack targeting the availability also referred as the denial of devices attack. Attempt to block,
delay, unethical, the communication in the smart grid. Attack aiming the integrity illegally
modify the exchange data in the smart grid and the attack targeting the confidentiality acquire
unauthorized information from the sources of the network in the smart grid.
The smart grid communication security
All the systems of communication are the main constituent of the grid infrastructure. Different
communication such a wireless and wired can be utilized to transmit the data amid electric
utilities and smart meters. The wireless communication has some of the advantages over the
wired technologies like easy to connect to unreachable areas and Low cost. Normally, categories
of the infrastructure of information are required for the flow of information in the system of the
smart grid. The first move from electrical appliances and sensor to smart meters and another one
is between the center of the utility data and the electrical appliances.
Zig Bee; this is a wireless technology of communication that have least power usage, the rate of
data and the deployment cost. It is the best technology for the monitoring energy, lightning
automation of home and automation or reading the meter. The communication between the smart
meters, and the home displays are very important (Piccolo, 2010).
The zee bee is the best option for the management of energy and moderation of energy and ideal
for the grid implementation along with its robustness, mobility, simplicity low deployment costs,

Smart Grid 40
requirement of bandwidth and the procedure within the spectrum unlicensed, ease in execution
and networking. It also has advantages over the water, gas and electricity utilities such as the
reduction and control of loads and the advanced support for metering. There are some of the
problems of the zee bee such as the low capabilities, the small size of the memory and small
delay requirements.
Wireless mesh; is a network of mesh of a flexible network comprising the groups of nodes where
the node can form the cluster and every node can work as the router that is independent. The
characteristic of network self-healing help the signals of communication to get additional router
through the active nodes in case of the nodes move out of the network. In the smart meter
systems, all smart device is installed with the module of radio and every of them channels the
data of metering through the meters adjacent. Every meter performs as the signals repeater until
the collected data attains the access of the point of electric network. Then the data collected is
moved through the network of communication to the utility (Piccolo, 2010).
The mesh networking is cheap solutions with self-healing, which gives many advantages like
improving the performance of the network balancing the load on the network and spreading the
area covered by the network. Proper coverage can be given in the suburban and urban regions
with the capability of multichip routing. The nature of the network mesh enables the meters to
act like the signals repeaters. In the urban area, the network mesh has been influenced by the
challenges of coverage since the density meter cannot give the complete coverage of the
communication network.
Communication of cellular network; the available cellular networks can be the best option for the
communication between the utility and smart meter and between the nodes. The available
communication infrastructure avoids the utility from the additional time and cost of constructing

Smart Grid 41
a dedicated communication infrastructure. The cellular network exist already, the utilities do not
have to sustain the additional cost for the construction of the communication infrastructure
needed for the smart grid.
Powerline communication; these techniques use the existing power line to transmit the signal of
high speed from one device to another. It is the leading selection for the communication with the
electric meter because of the direct assembly with the meter and the effective implementation the
infrastructure in the town where the solutions attain the requirements of the utility (Radosavac,
2011).
Requirements of the smart grid
Security; storage and transportation of secure information are very important especially for the
grid control and purposes of billing. The efficient security should be developed to avoid the
cyber-attacks.
Availability and reliability of the system; providing the availability of the system is among the
prioritized necessities for the utilities of power. Ageing power infrastructure and increasing the
usage of energy are some of the motives for creating the unpredictability issue for the power
grid. The availability of the structure of communication depends on the technology that is
preferred. The wireless technology with reduced cost of installation is the proper selection for
large-scale smart grid deployment.
quality of service; the communication among the suppliers of power and the consumers of power
is the main issues to the smart grid, degradation of performance like the outage or delay may
affect the stability hence the quality of service must be delivered to sustain the necessities of the

Smart Grid 42
communication. There are numerous solutions applications of the smart grid that have been
established to enhance its performance (Smith, 2009).
CONCLUSION
The smart grid has been conceived as the development of the electrical power grid system due to
the increased diffusion of the distributed production by the sources of renewable energies,
however, with the other objectives of improving the consistency efficiency and the existing
power grid safety. Timely gathering of information about the failure of the equipment and
natural accidents are important in ensuring the proactive reliable and real-time diagnosis of the
possible faults of the smart grid. This makes the cheap technologies of remote sensing important
for the safe and efficient delivery in the smart grid. In this research, the technologies of
communication and necessities of the smart grid are deliberated, the components and how they
work are also elaborated. The future work, grid characteristics, cybersecurity of the grid, control
and energy storage of the smart grid are also well presented.
