基于主从博弈的微电网分布式能量管理策略

Distributed Energy Management Strategy of Microgrid Based on Master-slave Game

针对电力市场运营模式下,新能源微电网的整体优化运行与多方投资者的最大利益化之间的冲突问题,提出了基于双层主从博弈的微电网分布式能量管理策略。为充分考虑能源供需两侧的平衡,引入了电力交易代理商的概念,在用户侧提出基于消费者满意度和可调节负荷的综合需求响应策略;考虑源-荷双方的主动性和决策能力,建立了以电力交易代理商为领导者,分布式电源代理商和负荷代理商为追随者的交易决策博弈模型,证明了stackelberg均衡解存在唯一性,采用结合二次规划的差分进化算法对所提模型进行求解。通过对包含分布式电源和社区用户的案例进行分析,验证了所提模型和策略具有良好的收敛性和经济性。

Under the operation mode of power market,based on two-layer master-slave game,a distributed energy management strategy for the microgrid is proposed to tackle the conflict between the overall optimal operation of renewable microgrid and the maximum profit of each investor.To fully consider the balance between energy supply and demand,the concept of power trading agent is introduced,and an integrated demand response strategy based on consumer satisfaction and adjustable load is proposed on the user side.Considering the initiative and decision-making ability of power supply and load,the decision-making game model is established with power trading agent as leader and distributed power supply agent and load agent as followers.The existence and uniqueness of Stackelberg game are proved,and the differential evolution algorithm combining quadratic programming is used to solve the proposed model.The excellent convergence and economy of the proposed model and strategy are verified by the case study which include distributed powers and community users.
