Green and clean microgrids can effectively assist in achieving the "dual carbon" goal, and the large-scale integration of uncertain renewable energy has put forward higher requirements for the flexibility adjustment of microgrid loads. This article is based on the business model of shared energy storage, taking into account the electricity consumption and functional characteristics of various electrical equipment, establishing a virtual energy storage model for microgrids, fully considering the energy storage characteristics of loads, and collaborating with microgrid centralized energy storage devices to jointly optimize and manage microgrid loads, achieving low-cost operation of microgrids and full consumption of distributed power. Firstly, a micro grid virtual energy storage collaborative optimization framework based on shared energy storage was proposed, and the collaborative control process of energy storage load was elaborated in detail; Secondly, based on the adjustable characteristics of the load, virtual energy storage modeling is carried out for the load, including virtual energy storage capacity and charging and discharging cost models; Then, a multi-objective optimization model is established to minimize the operation of microgrids and reduce peak valley differences; Finally, the method proposed in this paper was validated through actual data.
