An optimal reactive voltage control strategy for regional power grids considering new energy consumption

Abstract

The voltage quality decline caused by the high proportion of new energy connected to power grids is a key factor limiting the capacity of new energy consumption. Therefore， an optimal reactive voltage control method based on the maximum capacity of new energy consumption is proposed. The new energy generation forecast data is used to assess the maximum generation capacity， establish the reactive voltage optimization model and solve the voltage control target at each node for forwarding decision control. According to the topological properties and operational characteristics of the regional power grids， dynamic zoning， strategy prediction， alarm blocking， and other concerning functions are designed to improve the safety and stability of the control method. The simulation analysis results of an example show that the method features ideal reactive voltage support and can promote new energy consumption in the regional power grids.
