Abstract:Advanced adiabatic compressed air energy storage(AA-CAES) is an electric energy storage system that can realize large capacity and long-time electric energy storage. In the process of energy storage, it will produce additional energy flows, which can be used as a micro integrated energy system. This paper constructs a general energy exchange analysis model based on the energy hub(EH), carries out modular matrix modeling for the internal components of AA-CAES, such as compressor, turbine and heat exchanger, and analyzes its thermodynamic characteristics and energy flow generation efficiency to study the multi energy flow supply scheduling strategy of AA-CAES. Finally, for the purpose of maximizing economical operation, an AA-CAES multi-energy flow optimization scheduling model based on energy hub matrix modeling is proposed, and the typical compressed air energy storage system equipment data is used for simulation verification. The simulation results show that AA-CAES as a micro integrated energy system has good economy, and can realize daily cogeneration, reduce the energy consumption of other heating systems, and improve the regional energy utilization efficiency.
