A Fast Certificate for Power System Small-Signal Stability [PDF]

2020 59th IEEE Conference on Decision and Control (CDC), 2020
Swing equations are an integral part of a large class of power system dynamical models used in rotor angle stability assessment. Despite intensive studies, some fundamental properties of lossy swing equations are still not fully understood. In this paper, we develop a sufficient condition for certifying the stability of equilibrium points (EPs) of ...

Virtual Inertia Control and Small-Signal Stability Analysis of Electric Vehicle [PDF]

International Journal of Industrial Electronics, Control and Optimization, 2023
In electric vehicles (EVs), the small size of the dc link capacitor results in significant voltage deviations when there are changes in load or uncertain fluctuations from the power resources. This causes a decline in voltage quality.
