不平衡电网电压下三相并网逆变器有功功率纹波抑制策略

This letter proposes an active power ripple mitigation strategy for the three-phase three-wire grid-tied inverter. Under the unbalanced grid voltage scenarios, the double-line frequency oscillation will have occurred on the inverter output power and the dc-link voltage. Traditionally, the three-phase four-wire or the three-phase four-leg topology could be adopted to deal with this issue. Besides, ...
