Abstract
bined utilization of renewables such as solar and wind energy is ing
increasingly attractive and is being widely used for substitution of oil-produced energy, and
eventually to reduce air pollution. In the present investigation, hourly wind-speed and solar
radiation measurements made at the solar radiation and meteorological monitoring station,
Dhahran (26832'N, 50813'E), Saudi Arabia, have been analyzed to study the impact of key
parameters such as photovoltaic (PV) array area, number of wind machines, and battery
storage capacity on the operation of hybrid (wind + solar + diesel) energy conversion
systems, while satisfying a speci®c annual load of 41,500 kWh. The monthly average wind
speeds for Dhahran range from to m/s. The monthly average daily values of solar
radiation for Dhahran range from to kWh/m2. Parametric analysis indicates that
with two 10 kW wind machines together with three days of battery storage and
photovoltaic deployment of 30 m2, the diesel back-up system has to provide about 23% of
the load demand. However, with elimination of battery storage, about 48% of the load
needs to be provided by diesel system. 7 2000 Elsevier Science Ltd. All rights reserved.
