Unified Energy Function Tailored to Inverter-Based Resources with PI Controllers for Transient Stability Analysis
Yifan Zhang, Hsiao-Dong Chiang, Yitong Li +1
The increasing penetration of inverter-based resources (IBRs) has fundamentally altered the transient stability characteristics of modern power systems. IBRs typically rely on prop…
Large-Signal Stability of Power Systems with Mixtures of GFL, GFM and GSP Inverters
Yifan Zhang, Yaoxin Wang, Yunjie Gu +5
Grid-following (GFL) inverters have very different large-signal stability characteristics to synchronous generators, and convenient concepts such as the equal-area criterion and gl…
Robustness of the Closest Unstable Equilibrium Point Along a P-V Curve
Robert Owusu-Mireku, H. -D. Chiang
In this paper, we study numerically the behavior of the closest unstable equilibrium point (UEP) on the stability boundary of a stable equilibrium point (SEP) of a post-switching p…
A Direct Method for the Transient Stability Analysis of Transmission Switching Events
Robert Owusu-Mireku, Hsiao-Dong Chiang
In this paper, we propose an energy-based method for the transient stability analysis of a power system transmission switching event. In this method the exit point of pseudo-fault…
