微网存在两种典型的运行模式：离网模式和并网模式。同时，两种模式之间的切换也应该实现无缝切换。考虑 到采用主从控制以实现无环流的微网中主变换器在微网中的重要地位，本文采用V/f电压控制做为离网时变换器控制方法， 通过逐步调整变换器输出电压使其跟随电网电压实现离网到并网的无缝切换；(There are two typical micro-grid operation modes: off-grid and grid mode mode. At the same time, switching between the two modes should also seamlessly switch. Taking into account the use of master-slave control in order to achieve free circulation piconet master converter important role in the micro-network, we use V/f voltage control as when the network from the inverter control method, through the gradual adjustment of the converter output voltage to it follows the grid voltage to achieve off-grid and seamless network switching )
