On the Convergence of the Current-Constrained Power Angle Curve of Virtual Admittance-Based Grid Forming Converters
Haoxiang Zong, Chen Zhang, Yu Zhang +2
The current-constrained power-angle curve (PAC) is crucial for the transient synchronization stability (TSS) analysis of virtual admittance-based (VA) grid-forming (GFM) converters…

Generalized Feedback Control Modeling Method for Control-Driven Converter Systems
Chen Zhang, Haoxiang Zong, Xu Cai +1
Converters-based systems like wind farms manifest themselves as control-intensive systems, where control-driven stability issues frequently occur, e.g., oscillations. Such issues a…

A Multilayer Eigen-Sensitivity Method Using Loop Gain Model for Oscillation Diagnosis of Converter-Based System
Haoxiang Zong, Chen Zhang, Xu Cai +1
Loop gain-based eigen-sensitivity (LGES) is a useful frequency-domain tool for oscillation diagnosis of converter-based system. However, the existing theory is still scant in two a…
