Lyapunov stability of smart inverters using linearized distflow approximation [PDF]

IET Renewable Power Generation, 2021
Abstract Fast‐acting smart inverters that utilize preset operating conditions to determine real and reactive power injection/consumption can create voltage instabilities (over‐voltage, voltage oscillations and more) in an electrical distribution network if set‐points are not properly configured. In this work, linear distribution power
