Complex network framework based dependency matrix of electric power grid

For large scale analysis of power grid using complex network framework a network matrix is formed. The elements of the matrix represents the pair dependency of various buses of the system. This matrix could be used as a measure of centrality of various buses of a power system. A simple test system is used to illustrate the idea behind the dependency matrix of the power system as well as to demonstrate the building procedure. Various standard IEEE test systems are used to find out network dependency matrix for those systems.
