An Additional Resonance Damping Control for Grey-Box D-PMSG Wind Farm Integrated Weak Grid
Tao Zhang, Songhao Yang, Zhiguo Hao +2
Considerable efforts have been made to address the resonance issue of the Direct-drive Permanent Magnet Synchronous Generator (D-PMSG) wind farm integrated power systems. However,…
Model-Free Fast Frequency Support of Wind Farms for Tracking Optimal Frequency Trajectory
Yubo Zhang, Songhao Yang, Zhiguo Hao +1
The fast frequency support (FFS) towards frequency trajectory optimization provides a system view for the frequency regulation of wind farms (WFs). However, the existing frequency…
Entire Period Transient Stability of Synchronous Generators Considering LVRT Switching of Nearby Renewable Energy Sources
Bingfang Li, Songhao Yang, Guosong Wang +5
In scenarios where synchronous generators (SGs) and grid-following renewable energy sources (GFLR) are co-located, existing research, which mainly focuses on the first-swing stabil…
Multi-Swing Transient Stability of Synchronous Generators and IBR Combined Generation Systems
Songhao Yang, Bingfang Li, Zhiguo Hao +4
In traditional views, the build-up of accelerating energy during faults can cause the well-known first-swing angle instability in synchronous generators (SGs). Interestingly, this…
