弱电网及畸变环境下基于阻抗相位整形的LCL滤波逆变器鲁棒并网电流控制

For the grid-connected LCL-filtered inverter, the grid current feedback active damping (AD) can assure a desirable bandwidth and a good robustness against certain parameter variations by using a minimal number of sensors. However, the inverter performance was seriously endangered by nonideal conditions at the point of common coupling (PCC), including background voltage distortions and grid impedan...
