Abstract
The active power and reactive power decoupling control is achieved using vector control oriented by grid voltage and close-loop control of d, q axis current as control strategy of the grid-connected inverter. The analysis of impact of filter capacitor on the phase of the grid current is emphasized, bringing forward a method of compensation in filter capacitor. The results of comparative simulations show that this method could eliminate the phase errors between grid voltage and current effectively. Finally, the simulation shows that the gird connected inverter with current compensation in filter capacitor has a good dynamic and static performance in power decoupling control.关键词
