N2 - Electric betweenness is presented for vulnerable line identification in power system based on equivalent admittance small-world model by considering all possible transmission paths between any "plant-load" pairs together with different generation capabilities and operating modes. Whereafter, the maximal transition capability is also proposed to represent the changing of power system in cascading failures. Numeric examples of IEEE-39 system and Northwest China Power Grid show that lines with higher electric betweenness always belong to long-distance connections or vulnerable lines in power grid, while the power grid itself is more vulnerable under the attack based on high electric betweenness. Moreover, simulation of cascading failures in IEEE-39 system shows that the maximal transition capability is also valid when cooperated with the existed index, connectivity level.
