Abstract：Through research,it is found that energy storage technology can well solve the challenges brought by the grid opera-tion of renewable energy.Aiming at the problems of low efficiency,short service life and high cost of the main energy storage tech-nologies at home and abroad,this paper proposes a four-stage series compressed air adiabatic compressed air energy storage(AA-CAES)system.AA-CAES has the advantages of simple structure,high efficiency,low cost and short construction cycle.First-ly,the thermodynamic simulation system model of AA-CAES is established by Aspen HYSYS software,and the charging process and releasing process of AA-CAES system are simulated to obtain the energy production characteristics of the system.The results show that the adiabatic compressed air energy storage system can improve the system efficiency and reduce the power generation cost.Under the conditions of optimal operating conditions,the efficiency of adiabatic compressed air energy storage system can be as high as 63%,compared with the 54%efficiency of the current domestic and foreign non-adiabatic compressed air energy storage system.
