N2 - Vulnerable transmission lines play an important role in the spread of cascading failures and blackouts, which threaten the security and reliability of power grid. To identify vulnerable transmission lines with the increasing complexity of interconnected power grid, a new index called synthetic vulnerability is discussed in this paper to identify vulnerable transmission lines, by simultaneously evaluating topological vulnerability and power flow transmission vulnerability. Furthermore, a risk evaluation metric is introduced with enhanced risky exponential utility function to quantify influences on the power grid after identified vulnerable lines trip. Numerical results on the IEEE 5-bus system and the IEEE 39-bus system show the effectiveness of the proposed indices and the identification methods.
