A new kind of wind and solar power generation system combined with energy storage system was proposed in the paper

in which the technology of wind compressed air energy storage

the technology of solar heat storage and the technology of gas-steam combined cycle power generation were combined together. This system not only tries using wind turbines to drive the compressors directly and solar collectors to heat the fuel

but also tries taking the gas turbine exhaust as heat source of the steam turbine to realize gas-steam combined cycle. The thermodynamic analysis and system benefit calculation shows that

the efficiency of the above wind and solar power generation system will be improved and the power grid can get a stable power supply. A better economic

environmental and social benefit will be achieved.
