摘要：
This paper presents a solution to address the limitations of single mode of operation, high cost, and low utilization of user-side distributed energy storage. A joint operation mode, called multi-microgrid-shared energy storage, is proposed, which combines electric energy self-management and energy storage sharing modes. The energy trading problem under this approach is tackled using a two-tier energy trading strategy based on hybrid game theory. The strategy considers the conflicting interests and information asymmetry among the microgrids. A master-slave game-two-tier energy trading model is constructed to maximize the revenue of the upper-level shared energy storage operator and the benefits of the lower-level integrated energy micro-grid aggregator. Additionally, a cooperative game is introduced among the members of the integrated energy microgrid aggregator to facilitate peer-to-peer transactions. A hybrid game optimization model between the shared energy storage operator and the integrated energy microgrid aggregator is established. Based on the Nash bargaining theory, the cooperation game is transformed into two sub-problems, namely, maximizing the benefits of the aggregates and distributing the cooperation benefits. The constructed multi-objective optimization problem is solved using a combination of the dichotomous method and the interactive multiplier method. Simulation results demonstrate that the proposed trading strategy improves the overall efficiency of the integrated energy microgrid aggregate, reduces dependence on shared energy storage operators, and validates the feasibility and effectiveness of the strategy. © 2024 Science Press.
