摘要
为了实现微电网的两种典型的运行模式(并网模式和孤网模式)间的转换,提出了一种在微网中设置模式控制器以及对主电源的控制逻辑进行优化的方法,并阐述了模式控制器和主电源变流器的具体控制策略,对并网有计划转为孤网、并网无计划转为孤网、孤网有计划转为并网这3种情况进行的仿真分析,证明了模式控制器以及主电源变流器控制策略的可行性。
In order to realize the mode conversion between the two typical modes of microgrid （grid-connected mode and islanding mode）, mode conversion controller is set up in the microgrid and the control logic of microgrid main power is optimized. And the specific control strategy for mode controller and main power converter is elaborated. Three kinds of simulation are made, i.e. the planned conversion from grid-connected mode to islanding mode, the unplanned conversion from grid-connected mode to islanding mode, and the planned conversion from islanding mode to grid-connected mode. The simulation results show the correctness and validity of the mode control strategy.
