Optimized Power Decoupling Control for Grid-Forming Converter Under Different R/X Ratios of Grid Impedance
In this brief, the power decoupling mechanism of grid-forming converter is analyzed, which indicates that the suitable voltage compensation is crucial for decoupling. Then, an optimized power decoupling control is proposed, which can provide positive or negative voltage compensation for decoupling, resulting in efficient power decoupling under different R/X ratios of grid impedance. Finally, the experiments validate the proposed method.
