Compressed air energy storage technology is one of the effective ways to improve the penetration rate of new energy electricity and the stability of the power grid. In order to fully study the steady-state performance of a 100MW compressed air energy storage power station, a variable operating condition model of a 5-stage compression 4-stage expansion configuration compressed air energy storage system was constructed. The thermal performance of the system and its influencing factors were studied using energy analysis and exergy analysis methods. The results show that under the design conditions, the electric to electric conversion efficiency and exergy efficiency of the 100MW compressed air energy storage system are 55.3% and 54.04%, respectively, and the expander is the main source of exergy loss in the system; The isentropic efficiency of compressors/expanders is the main factor affecting the thermodynamic performance of 100MW compressed air energy storage systems.
