摘要：
Integrated energy microgrid and shared energy storage, as greatly significant in improving system energy utilization, have gradually become the current research hotspots. How to establish a set of integrated energy microgrid optimization operation models under the background of shared energy storage is a problem to be solved urgently. First of all, the system operation framework is introduced in this paper and the function of each interest body in the system is analyzed. Second, the optimized operation models for the microgrid operator, the shared energy storage service provider, and the user aggregator are established. Furthermore, the game relationship between the microgrid operator and the user aggregator is analyzed, and the Stackelberg game model between the microgrid operator and the user aggregator under the background of shared energy storage is proposed, proving the existence and uniqueness of the Stackelberg equilibrium solution. Finally, a case simulation is performed on the MATLAB platform, by using the Yalmip tool and CPLEX solver to model and solve and the combination of the heuristic algorithm and the solver to optimize the strategies of the microgrid operator and the user aggregator. The results show that the proposed model in this paper can not only effectively weigh the interests of the microgrid operator and the user aggregator, but also achieve a win-win situation for the user aggregator and the shared energy storage operator. The adopted solution algorithm can protect the data privacy between the microgrid operator and the user aggregator. © 2023 Power System Technology Press. All rights reserved.
