Optimal Operation Strategy of Integrated Energy System Considering Compressed Air Energy Storage

Compressed air energy storage can store electricity and heat at the same time. In addition, CAES has lower energy storage costs and long life. This paper studies the operating characteristics and mathematical models of compressed air energy storage, and establishes a mathematical model of an integrated energy system containing electricity, heat and gas. On this basis, with the goal of optimizing the total cost, a scheduling model including compressed air energy storage to participate in the operation of the electric-heat-gas integrated energy system is constructed, and operation constraints such as power balance and ramp constraints are considered. Finally, a numerical example is analyzed to verify the effectiveness of the model.
