Vulnerability Assessment System of Complicated Power System Based on Four-Level Set Model
Hbepc Wuhan · 2013
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.
