Abstract:This paper presents a fuzzy version for evaluating the reliability of complex power systems. In the proposed algorithm, fuzzy set theory was used to evaluate the coefficients of different terms in reliability expression. The coefficients of the reliability expression are composed of system tie/cut sets and link capacities. The proposed algorithm has made it possible to on-line power system security assessment depends on the system history and past experience. The entire logic of the algorithm is explained in detail and verified through a numerical example.
