摘要：
Feedforward scheme of point of common coupling (PCC) voltage has been widely applied in grid-connected inverters to improve the harmonic suppression ability. However, when connected to weak grids, the variation of grid impedance poses a challenge to the system stability. Motivated by this, a new feedforward scheme with adaptive feedforward gain is proposed in this paper, which can retain strong harmonic suppression ability and guarantee high system robustness no matter in weak gird or in strong grid. Simulation and experimental results verify the effectiveness of the proposed control scheme.
