Abstract: In this paper, we devise a mitigation strategy against cascades considering the vulnerable transmission lines. Firstly, we convert the complex grid into its dual graph, and then rank the vulnerability of transmission lines by the modified theory of structural holes named M-Burt method. Finally, the mitigation strategy is used to upgrade the transmission line capacities utilizing the identification results in the system evaluation to bring about the mitigation. The simulations on the IEEE-39 bus system and the IEEE 118 bus system show that the M-Burt method can identify the vulnerable transmission lines effectively and the mitigation strategy by the M-Burt method can reduce the power blackout risks drastically.
