Critical node identification of smart power system using complex network framework based centrality approach

A method of critical node identification in a power system is presented in this paper. Maximum flow in a network is used to measure centrality of various nodes in the power system. The proposed approach is an improvement of previous methodology in the sense that it does not take into consideration shortest electrical distance as path to flow power. Instead of using normal steady-state condition maximum possible flow is considered. Simulation of various standard test systems are carried out to identify critical nodes.
