Abstract

An approach using fuzzy theory to consider the uncertainties in the reliability evaluation of power distribution systems is presented. Combining fuzzy number operations with the network-equivalent approach, an algorithm in which the input parameters and reliability indices are expressed with trapezoidal fuzzy numbers is established to calculate the reliability indices of distribution systems. This approach can indicates the possibility distribution of reliability indices and requires a little more calculations than the conventional methods. Also a practical example indicates the availability of the proposed method.
