In order to improve the energy efficiency of the multi-microgrid system and the benefits of ESS, this paper proposes a multi-microgrid system interaction and operation method containing microgrid operators, and establishes an integrated model of microgrid planning and operation under the multi-agent cooperation mode based on quantifying agent's benefits and demand response. Among them, the upper layer is a planning model targeting the integrated benefits of SESS-MG alliance, and the lower layer is an operation model targeting the costs of the MG alliance. In addition, to ensure the feasibility of the proposed cooperation method, the improved nucleolus based on satisfaction equalization is used to share the costs of the MG alliance. Simulation results show that the proposed model can effectively exploit the complementarity between multiple microgrids, reduce the operating cost of multiple microgrids and protect information privacy, and improve the economic efficiency and utilization of shared energy storage, which is mutually beneficial to both of them. At the same time, the improved nucleolus has less comprehensive deviation than the nucleolus, and the solution efficiency is greatly improved, which can maximize the subjective satisfaction equilibrium.
