Micro-Grid System Based on Compressed Air Energy Storage

With the development of the power system, wind energy was applied to micro-grid system as a distributed generation. The output of the wind farms has the characteristic of intermittence and fluctuation, which would influent the stability of micro-grid system and can be solved effectively by compressed air energy storage system, a new energy storage technology. Because of the advantage of fast response, high economic performance and small environmental impacts, it has an extensive application prospect. This paper builds a micro-grid system with wind power generator, and control the output of micro-grid system by using compressed air energy storage system. The simulation result verifies that the compressed-air energy storage system can effectively suppress power fluctuation and improving the stability of the micro-grid system.
