摘要复杂电力系统的脆弱性评估的关键是找出系统中可能被攻击而引起大面积停电事故的脆弱点。本文从大面积停电角度出发给出了复杂电力系统的脆弱性定义, 在此基础上利用复杂电力系统具备大量数据信息源的特点, 首次提出了描述受到各种攻击时系统脆弱性和系统数据信息源关系的四层集合模型。同时, 本文根据该模型, 运用关联聚类方法建立了一套新的、客观和实用的复杂电力系统脆弱性评估的指标体系和评估方法, 通过对国内某大型省级电力系统的评估算例说明了该方法可以有效找出复杂电力系统的脆弱点集合。

Abstract：The key to the vulnerability assessment of complicated power system is finding the vulnerabilities which could cause the large-area power outages under attacks. In this paper the concept of vulnerability of complicated power system is defined, and based on the definition and the feature that the complicated power system has a lot of data sources, a four-level set model which describes the relationship between the attacking methods and the vulnerability of complicated power system is first proposed. According to the model, a new, objective, practical vulnerability assessment indices and method of power system by use of relational cluster are built. The assessment result of a province power system demonstrates vulnerability set of the complicated power system could be found by the new method.

Key words： Vulnerability of complicated power system vulnerability assessment data source four-level set model relational cluster
