Compressed air energy storage is a large-scale energy storage technology developed on the basis of gas turbine technology,and is currently the most mature physical energy storage technology in addition to pumped-hydro energy storage.How to improve the conversion efficiency of compressed air energy storage system and further reduce the cost of energy storage is the focus of current research.This paper first uses the thermal balance simulation software EBSILON Professional to establish a thermal system model for compressed air energy storage system,and then makes analyses on the sensitivity of the main parameters that affect the electro-electrical conversion efficiency of compressed air energy storage system.Finally,the paper provides the direction and suggestions for parameter optimization.
