Summary
The green sources of energy are being encouraged to reduce the environmental
pollution and combat the global warming of the planet. A target of 12%(, usage Of
wind energy only has been agreed by the UNO Country members to achieve by 2020.
So. the power or the wind is being used to generate electricity both as grid connected
and isolated wind-diesel hybrid power plants. This paper performed a pre-feasibility
of wind penetration into an existing diesel plant of a village in north eastern part of
Saudi Arabia. For Simulation purpose, wind speed data from a near by airport and the
load data from the village have been used. The hybrid system design tool HOMER
has been used to perform the feasibility study. In the present scenario, for wind speed
less than 6.0 m/s the. the existing diesel power plant is the only feasible Solution Over
the range Of fuel prices used in the simulation. The wind diesel hybrid system
becomes feasible at a wind speed of 6.0 m/s or more and a fuel price of 0.1 $/L or
more. If the carbon tax is taken into consideration and Subsidy is abolished then it is
expected that the hybrid system become feasible. The maximum annual capacity
shortage did not have any effect on the cost of energy which may he accounted for
larger sizes of wind machines and diesel generators. It is recommended that the wind
data must be collected at the village Lit three different heights using a wind mast of
40m for a minimum of one complete year and then the hybrid system must be re-
designed. (c) 2006 Elsevier Ltd. All rights reserved.Copyright: King Fahd University of Petroleum & Minerals;
