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,…
CT Saturation Detection and Compensation: A Hybrid Physical Model- and Data-Driven Method
Songhao Yang, Yubo Zhang, Zhiguo Hao +2
Current transformer (CT) saturation is one of the dominant causes of relay protection devices' malfunctions, which pose a threat to the safe operation of the power system. To addre…
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…
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…
