Summary: | A large number of populations of the world live in rural or remote areas those are
geographically isolated. Power supply and uninterrupted fuel transportation to produce
electrical power for these areas poses a great challenge. Using renewable energy in off
grid hybrid energy system might be a pathway to solve this problem. Malaysia is a hilly
land with the gift of renewable energy resources such as solar energy, wind energy,
wave energy, tidal energy, biomass etc. There is a possibility to utilize these renewable
resources to produce electrical power and to limit the dependency on the fossil fuel. In
this perspective, a research is carried out to analyze the performance of three different
hybrid renewable energy systems suitable for different territories of Malaysia. Three
different hybrid renewable energy systems are off-grid PV-diesel hybrid energy system,
off-grid wind-diesel hybrid energy system and off-grid PV-wind-diesel-battery hybrid
energy system. The performance analysis of the three different energy systems have
been conducted for southern region of Malaysia, Cameron highlands of Malaysia and a
remote area named Kuala Lumpur International Airport Sepang station in the state of
Selangor, Malaysia. Real time field data of solar radiation and wind speed are used for
the simulation and optimization of operations using “HOMER” renewable energy
software. The analyzed system can assure the reduction of CO2 emission in about 16
tons per year in comparison with other energy system. The analyzed hybrid energy
system might be applicable for other region of the world where the climate conditions
are similar. The electrification process of the remote areas and decentralized areas are
being a vital fact for the improvement of its agricultural, eco-tourism and industrial
issues of various territories of Malaysia. Renewable energy resources can be used
extensively to fulfil the demand of expected loads of these areas. This dissertation
presents an analysis of an off-grid PV-diesel, wind-diesel and a PV-wind-diesel energy
system. The main objective of the present analysis is to visualize the optimum volume
of systems capable of fulfilling the requirements of expected loads for a decentralized
area of the region. From the analysis it is observed that according to the cost of energy
(COE) or per unit cost and the load demand for the three different conditions three
representative energy systems has been developed as follows southern region (PV
enriched area), Cameron highland (wind enriched) and the KILA Sepang station (solar
and wind both enriched) and the COE sequentially USD 0.895/kWh, USD 0.199/kWh
and USD 1.877/kWh. The load demand had been considered sequentially 38, 85 and
33kWh/d for the three different territories of Malaysia as follows southern region (PV
enriched area), Cameron highland (wind enriched) and the KILA Sepang station (solar
and wind both enriched). The main theme of this analysis is to minimize the electricity
unit cost and ensure the most reliable and feasible system to fulfil the requirements of
the desired or expected energy system using HOMER software. The decrement of the
CO2 emissions also can be identified from the simulation results (with experimental
data collected from Malaysian Meteorological department) by using that most feasible
renewable energy system. |
