| 摘 要： | 在概率论的基础上将风险理论应用于电力系统脆弱性评估,将电力系统定义为脆弱系统,并建立了一套评估电力系统脆弱性的风险指标和相应的算法,解决了传统的确定性安全评估方法不能满足电力市场以及复杂电力系统要求的不足.以此为基础开发了基于风险理论和风险指标的电力系统脆弱性评估软件,并以新英格兰测试系统为例说明了文中方法的先进性和有效性.

| Abstract: | Based on probability theory the risk theory was applied to the vulnerability assessment of power system. Here, the power system was defined as a vulnerable system and a set of risk indices to assess the power system vulnerability and corresponding algorithm were built, thus the defects of traditional determinsistic security assessment method, which cannot satisfy the requirement of electricity market and complicated power grid, could be overcome. On this basis, a risk theory and risk indices based power system vulnerability assessment software was developed. Taking the New England test system for example, the effectiveness and advanced property of the presented method were proved. |
