- Abstract
The objective of security analysis is to find the weak link of distribution network. The K(N - 1 +k) criterion based on the characteristics of distribution network was proposed for distribution network security analysis. According to the K(N - 1 +k) criterion, the electrical devices in the contingency set can be classified into two kinds. The first kind meets the requirement of the K(N - 1 +k) criterion. The rank preference optimal ordering (RPOO) was proposed to evaluate the damage degree of power system. The second kind does not meet the requirement of the K(N - 1 +k) criterion, and it is the weak link of distribution network. A numerical experiment shows that the method is efficient and feasible, and the proposed method can provide assistant decision-making for safety precautions.
