Abstract
Now a day's electricity is most needed facility for the human being. All the conventional energy sources are depleting day by day. The combination of two energy resources i.e. wind and solar energy. Solar panels are used for converting solar energy and wind turbines are used for changing wind energy into electricity. The generating dispatch able electric power using wind and solar thermal energy combined through compressed air for transmission and storage and large area solar air heating collector integrated with high temperature capacity thermal storage media. The essential subsystems include wind turbines directly coupled to air compressors, high pressure large diameter pipeline, solar collectors with integral thermal storage for air heating, and a turbo–expander driven generator. This hybrid power generation system will be particularly useful in electric systems, such as the Electric Reliability Council of Texas (ERCOT), with very large wind energy potential, severe transmission limitations in very windy locations, areas of high solar radiation, and a significantly higher market value for dispatch able power than for intermittent energy. This hybrid wind / solar system would be a more economical means for achieving zero–emission, firm, dispatch able capacity than independent construction of wind and solar plants.
