基于合作博弈的微电网群运行优化方法研究

针对微电网群运行提出了一种采用纳什议价理论的合作博弈方法，对并网的微电网群建模并求出其最佳容量配置和最佳容量配置情况下的最大收益。通过纳什议价方案分配发电资源和蓄电池的容量，使单个微电网及其微电网群的年利润最大化。使用粒子群优化算法，通过MATLAB软件求解最优纳什议价方案。最后，针对电价和贴现率进行了敏感性分析，验证了所提微电网群系统优化结果的合理性。

Operation Optimization Method of Microgrid Group Based on Cooperative Game

The paper proposes a cooperative game method based on Nash bargaining theory for the operation of microgrid group，models the grid-connected microgrid group， and obtains its optimal capacity configuration and the maximum benefit with the optimal capacity configuration.The Nash bargaining scheme is used to allocate power generation resources and battery capacity， maximizing the annual profits of both a single microgrid and the microgrid group. The optimal Nash bargaining scheme is solved by using particle swarm optimization algorithm in MATLAB software. In the end， the sensitivity analysis is carried out for electricity price and discount rate to verify the rationality of the optimization results of the proposed microgrid group system.
