含风电的链状电力系统频率动态分布特性分析
Analysis of Frequency Dynamic Distribution Characteristics in Chain-structured Power System with Wind Power
摘要
Abstract
The integration of renewable energy generation,represented by wind power,into the power system has a significant impact on frequency security,and the frequency distribution characteristics have gradually become a focal point of attention.To study the influence of wind power integration into multi-machine systems on frequency distribution characteristics,based on the frequency response characteristics of the"grid,source,and load"sides,this paper constructs an analytical model of the frequency response distribution characteristics of a multi-machine system with wind power,and analyzes the impact mechanism of wind power integration on the frequency distribution characteristics.Then a multi-dimensional quantitative index system is developed to describe the relative dispersion and absolute differences in frequency response.Next,the validity of the mechanism model is verified using a simple chain-structured power system with"generation-transmission-reception",and the influence rules of electrical distance,wind power integration location,and disturbance location on the frequency distribution characteristic indices are analyzed.Finally,the influence rules of distribution characteristics are analyzed and verified in an actual large-scale power system with a high proportion of renewable energy.关键词
