Optimal configuration of PV/PT/AA-CAES capacity of micro IES considering energy coupling

In the dual carbon development environment, flexible combined renewable resources and energy storage system IES (integrated energy system) becomes more and more important. Analyzing the coupling mechanism of multi-energy plays a significant role in low-carbon IES planning and operation. Therefore, in this paper, after fully considering the advantages of advanced adiabatic compressed air energy storage (AA-CAES) in micro IES, the configuration and scheduling strategy of the micro IES with photovoltaic/photothermal (PV/PT)/AA-CAES is optimized. Firstly, CCHP (combined cooling/heating/power) characteristics of AA-CAES are modeled in detail. Secondly, bi-level programming method is employed to solve the problem. Capacity is optimized in the upper level with the objective of minimizing the operation cost and the fixed cost. Dispatch cost and the cost of carbon are optimized in the lower level. Finally, the method proposed in this paper is simulated and analyzed with an industrial park.
