Abstract Based on the complex network theory, this paper proposes a critical lines evaluation method for power network according to the cohesion degree of network. This method focuses on the overall state of the power network, the connectivity between nodes in the power network and the numbers of nodes in the network. It can measure the importance of each transmission line in power network by observing the change of cohesion degree of power network before and after transmission line breaking. Because of the comparison between the calculation results of this paper and the results of the existing critical lines evaluation schemes based on the network performance in the literature, the simulation on the topological structure and dynamics, the reasonable and effective of the method is proved.
