基于独立通道设计的非平衡电网阻抗下LCL滤波三相并网逆变器精确分析与设计

Three-phase grid-tied inverter with LCL filter is usually designed to operate under symmetric grid impedance. However, in actual operations, the equivalent three-phase grid impedance tends to be unbalanced, which turns the three-phase grid-tied inverter with LCL filter into a highly coupled multiple-input-multiple-out system. Traditionally, the impact of the cross-coupling on the stability is dire...
