Active and reactive power control for three-phase grid inverters with proportional resonant control strategies

Abstract

In this paper, the active and reactive power control applied for a three-phase grid inverter with proportional resonant control strategy is proposed. Both active and reactive powers are controlled and regulated by current-loop on stationary reference frame. The design methodologies of proportional resonant controller and low-pass filtering are presented. Finally, the proposed method is evaluated by simulations and experiments. The good agreement between simulated and experimental results is achieved. © 2016 IEEE.
