Summary:Reliability assessment of power systems is very vital particularly in the market-driven environment. As the power systems are nonlinear and large-scale systems, extracting their reliability indices involves much uncertainty. Calculation of power system reliability using stochastic methods is a complex and relatively difficult procedure. However, using fuzzy logic methods it would be possible to calculate the reliability in accordance with the existing uncertainties. In this paper, a new fuzzy logic based method is proposed to calculate the reliability indices of composite power systems. Then, the suggested method is examined on a sample network as a case study.
