一种微网结构的能量管理策略仿真研究

摘要

介绍了微网的控制方法和能量管理策略,研究了微网能量管理控制,分析了孤网情况和并网情况下的能量管理策略,采用了PSCAD/EMTDC软件对在孤网情况下的负荷投切、负荷变化情况以及在并网条件下对各微电源输出功率发生改变时的情况进行了仿真分析,其结果验证了所提微网控制方案的有效性及可行性.%The control method and the energy management strategy for microgrid are firstly introduced in this paper.Then,the energy management control of microgrid is investigated.The energy management control strategies are also analyzed under islanding condition and grid-connected condition.The PSCAD/EMTDC software is used to simulate the load switching and load variation under islanding condition,as well as the output power changes of each micro power under grid-connected condition.The simulation result has proved the feasibility and validity of the proposed method.
