Risk Assessment of Transmission Lines Based on Complex Network and Fuzzy Probability

Abstract:

Article Preview

This paper proposed an innovative way based on the complex network theory and fuzzy mathematics. A new index is introduced to evaluate the performance of power lines, which is more consistent with the physical characteristics of the actual power system. Fuzzy mathematics is proposed to the risk assessment in order to describe the uncertainty of the grid. This method considers both the membership degree of lines and the probability of failure. The result not only can determine the influence of the line, but also analyze the sphere of the fault line in power grid. This method is illustrated in the IEEE-39-bus, which demonstrates its effectiveness.
