The goal of this paper is to present a lab simulation experiment on design, simulation and analysis of
Stand-alone/Grid-Connected Renewable Power System for Residential Use for a place located in
Victoria. The main resolution to be tackled in this report is how to optimize energy resources based on
the available renewable energy. There are many energy resources currently available in Victoria, most
of which are renewable. This renewable resource can be utilized to manage the increasing energy
demand. Basing on the above considerations, various energy resources have been incorporated in this
design. Solar energy and wind power have been incorporated with utility grid, the utility grid has been
tapped from the nearby power supply.
A diesel generator has been used as a backup together with a solar battery. These components are
reliable to provide constant energy supply to the Victoria region. The feasibility analysis of the solar
power and wind energy will also be studied in this paper.
Introduction
Renewable energy utilities are distributed over different geographical areas throughout the world, this
is in contrast with non-renewable electrical energy resources which are on found in few or limited
countries in the world. The increase in utilization of renewable energy resources over the modern days
have led to reduction of energy shortages[2], mitigation of change in climate and also merits in
economic development [3]. Recent research has concluded that most of the climate change has been
induced by use of non-renewable energy sources, this have led to increase in the greenhouse gas, non-
renewable energy consumption that produces CGH gas should be held liable for the air pollution [5],
scientist have proposed that the main mitigation that could be done to reduce environmental
degradation are curb climate is to adopt renewable energy resources. Based on international public
surveys, people support the use and implementation of renewable energy sources such as solar power
and wind power [3]. At the international level, more than 30 countries have installed at least twenty
percent of the total national grid be from renewable energy sources. The world market for the
renewable energy sources is expected to increase by twenty percent in the coming decades, this could
even go beyond as stated by the Australian energy regulation bodies. Other countries, such as Norway
and Iceland have more than 95% of the total energy used sourced from renewable energy sources and
many other nations have a target of achieving 100% of their energy to be from renewable energy
sources. Examples include countries such as Denmark which switched to achieving renewable energy
use by 2050.

Modelling, Simulation and Optimisation Results
Modeling
The modeling of a Microgrid system involved a choice of different components integrated together.
The components used were as provided below.
 back-up generator (diesel or gas micro turbine)
 a utility Grid
 a PV system
 a converter and a battery
 Wind turbine.
Justification of component design choices used in modelling
back-up generator (diesel)
a diesel generator was used for off-grid power production. Diesel was preferred for its availability and
flame factor. The diesel generator used has a high capacity installed, the shaft efficiency is high, rapid
start and stop and with a minimal exhaust heat. This makes this generator more advantageous for the
simulation. In this model 2.6kW capacity diesel generator is used [13] [8]
a PV system
PV system utilizes the natural solar energy to produce power. A generic flat PV was chosen for this
modeling. It produces a 1kw/hr. its relative costs and maintenance is cheap.
The results provided in table below shows the systems justifications based on previous years[9].

Convertor
Convertor was needed to convert the direct current from solar PV system and Battery
Battery
100kwa lithium ion battery is usedin model diagram because of its durability and efficiency in storing
power. The costs requirements and the maintenance cost used was 1000$ [7]
Wind turbine
Wind resources have been a good energy resource for a long time. It is important to recognize wind as a
renewable energy source. Wind speed of 6m/s was used for this case.
