不平衡电网条件下交流侧无电压传感器三相变换器的功率解耦

In order to support the grid, it is desirable for distributed generation systems to remain operational during grid faults. However, under such scenarios, existing methods for grid current injection do not guarantee the absence of power pulsations on the dc-bus. To address this issue, this work proposes a power decoupling strategy for an ac-side, LCL-filtered, grid-tied dc–ac three-phase converter ...
