LCL型并网逆变器谐波振荡中被忽视的元凶：谐振极点抵消

Resonant pole cancelation is usually adopted in the current control or active damping to tackle the filter resonance in the LCL-type grid-connected inverter. However, its potential impact on the system stability has not been adequately assessed. This article provides a comprehensive investigation on three typical control schemes that utilize resonant pole cancelation. An important finding is drawn...
