【摘要】 风能、潮汐能、光能等可再生能源接入电力系统,在一定程度上使得电力系统脆弱性凸显的趋势增加。在风电系统的特性与模型的研究基础上,分别从结构脆弱性和状态脆弱性2个角度对电力系统脆弱性进行理论分析和研究,给出较为科学的风电电力系统脆弱性定义,建立系统脆弱性综合评估指标集。对一级脆弱性指标和二级脆弱性指标进行量化、权重分配、指标融合,建立含风电接入的电力系统脆弱性量化模型。通过IEEE39系统标准数据集进行电力系统的脆弱性计算与仿真,验证了理论研究的正确性,并识别了系统的薄弱环节。更多还原

【Abstract】 The access of renewable energy such as wind energy,tidal energy and solar energy to the power system increases the vulnerability of the power system more obviously.Based on the characteristics and models of the wind power system,this paper analyzes and studies the vulnerability of power system from the perspectives of structural vulnerability and state vulnerability,and gives a more scientific definition of vulnerability based on the wind power system,and establishes a comprehensive set of indicators for system vulnerability assessment. The quantification,weight distribution and index integration of the first-level vulnerability index and the secondlevel vulnerability index are realized,and a quantitative model based on the vulnerability of the wind power system is formed.The vulnerability calculation and simulation based on wind power system is carried out through the IEEE39 system standard data set,which verifies the correctness of theoretical research and identifies the weak link of the system.更多还原
