To improve the energy utilization rate and realize the low-carbon emission of a park integrated energy system (PIES), this paper proposes an optimal operation strategy for multiple PIESs. Firstly, the electrical power cooperative trading framework of multiple PIESs is constructed. Secondly, the hydrogen blending mechanism and carbon capture system and power-to-gas system joint operation model are introduced to establish the model of each PIES. Then, based on the Nash bargaining game theory, a multi-PIES cooperative trading and operation model with electrical power cooperative trading is constructed. Then, the alternating direction method of multipliers algorithm is used to solve the two subproblems. Finally, case studies analysis based on scene analysis is performed. The results show that the cooperative operation model reduces the total cost of a PIES more effectively compared with independent operation. Meanwhile, the efficient utilization and production of hydrogen are the keys to achieve carbon reduction and an efficiency increase in a PIES.
