寒旱地区分布式新能源配电网过电压控制方法
Overvoltage Control Method of Distributed New Energy Distribution Network in Cold and Dry Areas
摘要
Abstract
The random variation of irrigation load and the nonlinear dynamic variation of distributed wind energy in the cold and drought region bring about the complex transient overvoltage with high confusion type.Taking a typical daily two-stage peak load line in an agricultural area of eastern Mongolia as an example,a distribution network system model considering irrigation load and new energy access was built,and the characteristics of voltage amplitude distribution were compared and analyzed in various ways.The simulation results show that distributed new energy can alleviate the power demand of irrigation peak load,but it will produce overvoltage problem.Adding energy storage system can alleviate voltage amplitude,but centralized energy storage system is inferior to distributed energy storage system in termi-nal voltage processing.The application in the typical agricultural area of eastern Mongolia alleviates the voltage problem during irrigation peak hours,and the relevant conclusions provide a technical reference for distributed new energy with high permeability.关键词
