Vulnerability assessment is one of the effective ways to prevent cascading failures of a distribution network (DN). Considering topological structure and operation status, a comprehensive assessment method based on the technique for order preference by similarity to ideal solution (TOPSIS) is proposed to accurately identify the vulnerable parts of the DN. In the method, the improved structural vulnerability indices based on complex network theory are defined, such as degree and network efficiency. And the electrical betweenness and power flow transfer entropy are established to evaluate the st...
