Finally, through the modified IEEE39 node AC/DC hybrid power grid, the results show that the proposed method can effectively identify the key lines in the development of cascading faults in the AC/DC hybrid power grid. According to the probability of the line in the fault sequence, modify the local criticality, calculate the comprehensive criticality of the line, and identify the key line. The local criticality of the line in a specific fault chain is calculated based on the improved fuzzy analytic hierarchy process. The propagation relationship of the line in the cascading faults and the fault characteristic indexes such as electrical structure degree, weighted power flow transfer entropy, voltage offset, and load loss are comprehensively considered. The cascading faults of the AC/DC hybrid power grid are simulated, and the cascading fault sequence is obtained. Aiming at the risk of a large outage caused by cascading faults of the AC-DC hybrid power grid, a data-driven identification method for key lines of the AC-DC hybrid grid is proposed.
