摘　　要：在绿色经济和新能源快速发展的背景下,可再生能源供电得到了迅速发展。为应对分布式能源波动性大、抗干扰能力较弱的问题,探索以可再生能源供电为主的独立供电微网群运行策略具有重要意义。根据微电网的规划建设及相应控制模式,提出了微电网独立运行与互联运行的策略。为了减少微电网独立运行中的弃风、弃光现象,提高其经济效益,以最小化微电网独立运行成本和最大化微电网互联运行社会效益为目标,建立了涵盖微电网内部调度与微电网间调度的双层优化模型。采用交替方向乘子法(alternating direction multiplier,ADM)进行迭代求解,以获得兼顾各个微网络体及其群体整体运营效益的可再生能源输出功率、储能输出功率以及购售电策略。最后,通过对14节点独立供电微网群进行仿真分析,验证了所提模型的合理性及方法的有效性。Under the background of the rapid development of green economy and new energy,renewable energy power supply has been developed rapidly.In order to deal with the problems of high volatility and weak antiinterference ability of distributed energy,it is of great significance to explore the operation strategy of independent power supply microgrid group dominated by renewable energy.According to the planning and construction of microgrid and the corresponding control mode,the independent operation and interconnected operation strategies of microgrid are proposed.In order to reduce the phenomenon of abandoned wind and light in the independent operation of microgrid and improve its economic benefits,this paper established a bi-level optimization model covering the internal and inter-microgrid scheduling with the goal of minimizing the independent operation cost of microgrid and maximizing the social benefits of microgrid interconnected operation.The alternating direction multiplier(ADM)method is used to solve the problem iteratively to obtain the renewable energy output power,the energy storage output power,and the electricity purchase and sale strategy that take into account the overall operation efficiency of each micro-network body and its group.Finally,through the simulation analysis of 14-node independent power supply microgrid group,the rationality of the proposed model and the effectiveness of the method are verified.
