Optimal Configuration Method of Reactors in Distribution Network with Photovoltaic Power Based on Genetic Algorithm

Abstract

Large-scale photovoltaic power connected to the distribution network will raise the voltage at the system nodes， and， in serious cases， the voltage overlimit. Therefore， a voltage regulation strategy based on shunt and series reactors as well as genetic algorithm is proposed. Firstly， the causes of voltage rise in the distribution network and the roles of shunt and series reactors in voltage regulation are analyzed. Then， a reactive power optimization model with the objective of economic optimization is established， and the genetic algorithm is used to solve the optimal reactor configuration scheme. Finally， the effectiveness of the method is verified by simulating the IEEE 33-node system incorporated into a high-power PV plant based on the MATLAB simulation platform.
