Operational strategies for Kuwait's 100 kW sub(e)/0.7 MW sub(th) solar power plant

In March 1981 a 0.7 MW sub(th) solar thermal power plant was commissioned at Kuwait's Sulaibiya Solar Complex. The cogeneration of solar power plant was designed to be the main energy supplier for an agricultural desert settlement 35 km south-west of Kuwait City. The power plant produces both the electric and thermal energy needs for its own internal uses and those of the food/water/power complex. During periods of low solar radiation the power plant may be operated at partial load to supply the essential electric energy needs, charge the thermal storage, or provide the thermal energy needs for the MSF desalination system. An energy cost accounting system was developed to encourage the user to minimize his electric consumption during periods of low solar radiation. A mathematical energy model for the power plant was utilized to predict its output and suggest the optimum operational strategy according to the user's priorities, and predict surpluses or shortages that have to be accommodated by the emergency secondary energy source.
