Optimization of Compressed Air Energy Storage System Parameters

Abstract:

In this current paper, the influence of system efficiency and system parameters for simple compressed energy storage system were studied. EES software is used to simulate the pressure of system and efficiency of compressors, expanders, and pump for getting the optimal parameters of system. The results show that: for the simple system, when the expander inlet pressure is 6000kPa and compressor outlet pressure is 4000kPa, the system efficiency could get the maximum, and it is 76.2%. It is a better way for improving the efficiency of compressor and expander than the pump for system performance.
