Executive summary
The paper focuses on analysing the feasibility of implementing a hybrid energy
system at scone region, upper Hunter Shire council area. The Energy mix will
comprise of three energy sources: solar photovoltaics, wind energy and fossil fuel
energy. The expected energy production ratio of this sources is 6:3:1. The Grid will
supplement the system in case of low production. Surplus Energy will also be
connected to Grid; hence the system will be connected to the national Grid. Homer
pro software will be used to analyse the optimal and feasible energy mix for the
region, with carbon gases emission among other economic comparison for the
proposed model.
Introduction
For several years, sustainability has been used to define the need to
carry out operations while maintaining resources or to impose non-harmful
outcomes as induced by human operations. According to the Brundtland
Commission, sustainability has also been described as meeting the present
human requirements without revoking or rendering future generations
unable to meet their requirements from the funds available (Brundtland
Commission, Our Common Future 1987). There should be no confusion
between the fundamental problem of resource depletion and social and
economic characteristics1.
Technological advancement, coupled with increase in population has
resulted into increased demand for energy. Most of the energy techniques
that currently we have been non-renewable sources, which are bound to
depletion in the near future. Additional, in ordinary set-ups, the rural areas
tend to experience limited challenges in regards to provision of electricity.
On contrary, one of the major challenges faced by technology is the
provision of reliable and cost-efficient power solutions in both the remote
and rural areas. Taking our case study for instance: upper hunter shire is
basically composed of few towns on the upper hunter such as Aberdeen,
scone, Merriwa and Murrurundi with a number of villages including but not
limited to Blandford, Gundy, Bunnan, Wingen, Cassilis, moon a flat, and
Ellerston. It has an increasingly growing population as from the census
records; however, the total population is still relatively low: fifteen thousand
people as per the 2016 census. The town is governed by town council. Our
case study focuses on a request to design a system that would be able to
meet the energy demands of the residence of scone town. The town has an
elevation of 216 m, with the weather values being: 9 ° C, North Wind 3 km /
h, 89% humidity. Its climatic conditions are: Summer temperatures average
31.6° to 16.9° and winters 16.5° to 3.4°. The mean annual rainfall is

616mm. (BOM data). In terms of the inhabitant’s occupations, agriculture
and fishing and forestry is the major practice conducted by the persons, with
mining and construction also being practised in the region?
These conditions thus give us the insight that we can practice both
photovoltaic method of harnessing energy, as well as wind energy, due to
the elevation of the place. When both systems are integrated together, they
form a hybrid system. When the hybrid system is connected to the grid, it is
regarded as a hybrid-on grid system, which ensures that there is reliability of
power through.
This paper provides an overview of the renewable hybrid electricity (HRES)
schemes. This sort of scheme reflects the current requirement for the
provision of a fresh source of electricity as a source of such demanding off-
select electricity. As stand-alone electricity generation systems in distant
regions, hybrid renewable energy systems (HRES) are increasingly common
owing to progress in the field of renewable energy techniques and ensuing
increase in oil goods prices. Two or more renewable energy sources are
generally used as a hybrid power scheme, together to improve the system
efficiency and equilibrium of energy consumption.
Globally, the standards for micro grid optimisation has been known as
homer. By definition, this is a computer model which makes it easier for the
optimisation of hybrid micro grids for the renewable sources of energy,
either connected to a large grid or remotely located.
