A Novel Transmission Line Vulnerability Evaluation Method Based on Complex Network Theory

As further development on the applications of CN (complex network) theory, evaluation of transmission line vulnerability requires the consideration of physical attributes of power system, instead of simply considering its topology features, which helps to deduce more precise predictions for the stability of power system. This paper introduces a novel and efficient evaluation method based on CN theory to evaluate influence of line faults to the static stability of power system, comprehensively considering the factors of system load level, power capacity utilization rate of transmission lines and worldlet features. The method is illustrated in the IEEE118 bus system.
