Study on Primary Frequency Modulation Parameter Setting of Compressed Air Energy Storage

Abstract

With the advantages of large storage capacity, long storage cycle and little pollution to the environment, compressed air energy storage is considered to be one of the most promising technologies for large-scale power storage. The great intermittency and volatility of photovoltaic and wind power will cause a large disturbance to the frequency of power grid. It is necessary to study how to use energy storage technology to maintain the frequency stability. According to the national standard, and referencing the same type of generation unit, the primary frequency modulation function of compressed air energy storage is constructed. Combined with its own characteristics, the parameters such as dead band, speed governor droop and limit bound are analyzed and set up, which lays the foundation for compressed air energy storage to participate in primary frequency regulation of power grid.
