In order to eliminate the influence of the output filter capacitor current on the grid current , a novel control strategy for the grid - connected inverter in grid - tied and off - grid modes is proposed . the control strategy can also realize seamless transfer between grid - tied and off - gird modes . the grid - connected inverter can supply power to the critical load when the grid is off 本文针对传统并网控制策略进网电流受输出滤波电容电流影响的问题,提出了一种新的并网控制策略,该控制策略能基本消除输出滤波电容对进网电流的影响,实现独立与并网两模式之间的无缝切换,对关键负载起不间断供电的作用。
