Application of centrality measures of complex network framework in power grid

The classical definitions of various centrality measures are modified to incorporate electrical parameters of the power grid. In this paper three distinct measures of centrality are presented and they are described with suitable examples. The usefulness of these measures are described. Various standard test systems are simulated to find critical nodes of the system. Complex network is a new area of research in power system. Simulation of several systems suggests that the definitions proposed in this paper can be used as a standard.
