Abstract

Vulnerability reflects the ability to withstand cascading failures in the event of a power system failure. The power flow occurs after the power system N－1, and the system power flow redistribution increases the power flow of the system grid part, which may lead to cascading failure and large-area power outages. How to prevent the cascading failure of the system line after N－1 is necessary. From the perspective of vulnerability, this paper analyzes the vulnerability of power system lines; first of all, calculates the outage distribution factor of each branch. Based on this, the line state vulnerability index and calculation method are proposed, and the state vulnerability assessment results of each branch are obtained. Then, this paper visually analyzes the ability of a line to withstand faults and the impact of the line breaking on other line currents. Finally, the IEEE-39 node system is taken as an example to verify the feasibility of the method and the guiding significance of preventing cascading failure by calculating the state vulnerability index of each branch.
