Compressed air energy storage (CAES) system is a new type of energy storage system with characteristics of long-term performance, high efficiency, and safety. In recent years, adiabatic CAES technology has attracted extensive attention. In this paper, the thermal models and the solution processes of the CAES system are proposed, which are verified by the design and operating data of the adiabatic CAES project in Jintan, Jiangsu province. And then, according to the comparison of different CAES technology routes, this paper selects the 300MW medium temperature CAES system with rock cavern for analysis. With the project in Yongchun, Fujian province as an example, the optimal scheme is to select the expander inlet pressure of 17MPa and the inlet pressure variation range of 6MPa, and the thermodynamic processes and technical parameters of this scheme are analyzed. According to the analysis above, a preliminary design plan is obtained.
