•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.
Power grid vulnerability to targeted attack has been a focus of research after the robust yet fragile nature of complex systems was discovered. Various measures has been proposed to analyze the topological fragility since then. This paper focuses on providing a matrix which is able to find out critical elements within the system. A step by step method for building the matrix is shown. Various vulnerability measures has been discussed with examples.
