Transient Stability Analysis of a Hybrid Grid-Forming and Grid-Following RES System Considering Multi-Mode Control Switching
Ruiyuan Zeng, Ruisheng Diao, Fangyuan Sun +3
The inherent control switching of renewable energy sources (RESs) during intricate transient processes introduces complexity to the dynamic behavior of modern power systems. This p…
Improved PLL Design for Transient Stability Enhancement of Grid Following Converters Based on Lyapunov Method
Fangyuan Sun, Ruisheng Diao, Ruiyuan Zeng +2
Fluctuations in phase angle and frequency under large disturbances can lead to loss of synchronism (LOS) in grid-following (GFL) converters. The power angle and frequency of synchr…
