Revisiting Voltage and Synchronization Stability Analysis in Grid-Following Converter-Integrated Weak Grids: Insights from Non-Minimum-Phase Zeros
Fuyilong Ma, Lidong Zhang, Wangqianyun Tang +4
The increasing penetration of grid-following (GFL) converter-interfaced generators (CIGs) intensifies concerns over small-signal voltage and synchronization stability. While existi…
Localization and Reshaping of Non-Minimum-Phase Zeros in Multi-Converter Systems
Ailixier Yaermaimaiti, Jiaxin Wang, Yunjie Gu +1
Non-minimum-phase (NMP) zeros in multi-converter power systems impose bandwidth ceilings on feedback control, yet quantifying them at the system level has been impractical because…
