A novel voltage regulation control method of distribution network based on switched affine model

In order to solve the distribution of voltage quality problems, this paper presents a new voltage regulation control strategy of distribution network based on switched affine model. By establishing the state space equation of the controllable series voltage regulation device, using the method of Lyapunov function and quadratic stability theory, according to the convex combination stability theory, the common Lyapunov function of each subsystem is constructed, and each subsystem is divided into the new area. This switched rule can make the switching system always run in the minimum value of Lyapunov function derivative of the subsystems and ensure system of quadratic stability under arbitrary switched rule. The performance of the controller is verified to be very effective and feasible through the MATLAB simulation.
