Novel Region of Attraction Characterization for Control and Stabilization of Voltage Dynamics

Bai Cui, Ahmed Zamzam, Guido Cavraro +1

In this paper, we study the monitoring and control of long-term voltage stability considering load tap-changer (LTC) dynamics. We show that under generic conditions, the LTC dynami…
