This paper established the mathematical model for the expansion side core equipment of 350MW level advanced compressed air energy storage system.Based on the EBSILON thermodynamic simulation software,the influence trend of different expander gas distribution methods on the thermal performance of the compressed air energy storage system is simulated and calculated.The calculation results show that when using the"throttling + overload valve"gas distribution method,the overall operation economy of the compressed air energy storage system is higher,and the larger the pressure fluctuation range of the gas storage tank,the more obvious the economic advantage,and the better the load response ability to respond to the peak shaving and frequency regulation commands of the power grid.
