Abstract Aiming at the demand of key link identification in power system security defense, the paper puts forward the concept of grid key line sequence. Based on the structural vulnerability indexes and network performance indicators, this paper constructs the comprehensive importance index of line sequence and selects key line sequence in combination with the multiple attribute decision making method. Regarding multiple attribute optimization and sort of large-scale line sequences, particle swarm optimization algorithm is given. Taken IEEE 39-node system and Hebei southern power gird as examples, the experimental results of searching key line sequences show that the proposed method can effectively filter the system key line sequences and provide guidance for power grid cascading failure prevention.

Key words： Power system line sequence key line multiple attribute decision making particle swarm algorithm
