Probabilistic Vulnerability Assessment of Transmission Lines Considering Cascading Failures

The prevention of cascading failures and large-scale power outages of power grids by identifying weak links has become one of the key topics in power systems research. In this paper, a vulnerability radius index is proposed to identify the initial fault, and a fault chain model of cascading failure...
