Abstract:A vulnerability assessment method based on organizational betweenness is proposed. Based on electrical network theory, firstly nodal injection current influencing factor index is deduced, the degree of transmission line interference is quantified. Combined with the comprehensive degree index of branches connectivity, the index of organizational betweenness of lines is defined. The simulation results of IEEE 39 node system show that the proposed method can effectively identify vulnerable lines in the power grid from the perspective of structuredness.
