In order to improve the efficiency of energy utilization

the integrated energy system (IES) has emerged. The IES typically acts as a whole system during operations

the subsystems are separated

and the interests of each system are independent. In this paper

considering the relationship between the various energy systems

non-cooperative game theory is used to establish the optimal dispatch model. The proposed model mainly relies on the relationship between the cooperation and competition among various subsystems to obtain the maximum benefit they can accept. Furthermore

the basic definition is combined with the particle swarm optimization algorithm to solve the problem. The results show that the optimization strategy proposed in this paper can operate safely and reliably

and effectively distribute the benefits of each energy system.
