摘要
Abstract
To study the mechanism of cascading failures in a power grid,it is necessary to find out the key vulnerable lines propagating cascading failures. Firstly,an index system that contains voltage deviation,power flow coefficient and electric betweenness is built,considering the network structure and the real-time operation state of the system. Then, the objective data and subjective opinion of experts are combined,and a line vulnerability assessment method is pro-posed. Numerical example results show that the proposed indexes can overcome the deficiency of the existing ones that do not take the states of the grid structure and operation into account,which proves the feasibility of the assessment method.关键词
