摘　　要：电价波动与微网间交易的欺诈行为对多微网协同运行构成挑战。为此,提出了一种考虑电价不确定性和博弈欺诈行为的多微网电能合作运行优化策略。首先,建立了综合能源微网模型,并引入需求响应机制和云储能系统。然后,基于纳什谈判理论建立了多微网电能合作运行优化模型,并将纳什谈判原问题等效转换成多微网系统效益最大化子问题和电能交易收益最大化子问题。前者采用机会约束与鲁棒优化方法,以应对风光与电价的不确定性并实现多微网系统效益最大化;后者提出一种中介交易模式,以实现微网间欺诈均衡和各微网电能交易收益最大化。最后,采用交替方向乘子法进行分布式求解,以保护各参与主体隐私。仿真结果表明,所提策略可以有效提高各主体的运行效益和应对不确定风险的能力。The fluctuation of electricity prices and the cheating behaviors in transactions between the microgrids pose great challenges to the cooperative operation of the multimicrogrid systems. Therefore, this paper proposes an optimization strategy of multi-microgrid power cooperative operation considering the electricity price uncertainty and the game cheating behaviors. Firstly, the integrated energy microgrid model is established, and the demand response mechanism and the cloud energy storage system are introduced. Then, based on the Nash game theory, the multi-microgrid electric energy cooperation operation optimization model is built, and the original Nash game problem is equivalent transformed into a multi-microgrid system benefit maximization subproblem and an electric energy transaction benefit maximization subproblem. The former adopts the opportunity constraints and the robust optimization method to deal with the uncertainty of wind, solar,and electricity prices and maximize the benefits of multi-microgrid system. The latter proposes an intermediary transaction mode to realize the fraud balance between the microgrids and maximize the benefits of the power trading in each microgrid. Finally, the alternating direction multiplier method is used for distributed solutions to protect the privacy of each participant. The simulation results show that the proposed strategy can effectively improve the operation efficiency of each subject and the ability to deal with uncertain risks.
