Bus dependency matrix of electrical power systems
A method for identifying critical nodes for smart and bulk power transmission grid environment is presented in this paper. A new model based on bidirectional power flow is considered. Applicability of these methods in smart grid environment is evaluated. The consequence of removing critical nodes found from the analysis is discussed. The efficacy of bidirectional model is studied through rank similarity analysis.
