Optimal Allocation of Shared Energy Storage in Multi-Region Integrated Energy System Based on Nash Negotiation

Shared energy storage and multi-zone integrated energy system have attracted much attention because of their advantages of significantly improving energy efficiency. The reform of electric power market makes the competition between multi-subjects increasingly fierce and the distributed characteristics more and more obvious. In this paper, shared energy storage and multi-region integrated energy system are regarded as different interest subjects, and the cooperative operation model of shared energy storage and multi-region integrated energy system is established based on asymmetric Nash negotiation game theory with the optimization goal of minimizing the total operating cost of each subject. An example is given to analyze the operating cost of each participant in the cooperation mode. Finally, it is verified that the proposed game model and distributed algorithm can give consideration to both individual and whole interests, which is more fair to each subject and ensures the stability of cooperative alliance.
