Abstract: The grid code requires that the grid-connected inverter inject powers to achieve the voltage recovery during grid faults. However, due to the grid harmonics, the power injection through the line impedance may affect the power quality at the point of common coupling and reduce the system reliability. In order to solve the problem, the relationship between grid harmonics and PCC voltage was analyzed. Then a new voltage recovery control strategy is proposed. It adjusts the control coefficients of positive/negative sequence and harmonics to improve the voltage quality. Finally, the experimental tests of the conventional and proposed control solutions were carried out. The experimental results verified the effectiveness of the proposed method.
