Study of a Hybrid Wind and Solar Energy Power System

Abstract:

A new kind of hybrid wind and solar energy power system was proposed in this paper. In the hybrid system, the technologies of compressed air energy storage (CAES), solar heat storage and gas-steam combined cycle power generation were combined together. At same oil consumption of 19.48 t/h, the output power of the hybrid system in the paper was 194.69 MW, while that of the conventional gas-steam combined cycle was 103.15 MW. The difference between the two cycles was 91.54 MW, which was equivalent to the amount of wind and solar energy power generation. When annual effective operating time of the hybrid system was 2600 h, the power output of wind and solar energy power generation reached 238 million kW•h. If coal-fired power plants were taken as the reference standard, about 113,050 tons of coal was saved per year. An overall benefit of Ұ604.28~626.01 million was obtained per year. As a result, a good economic, environmental and social benefit was achieved.
