Abstract :
An artificial neural network (ANN) approach is presented for evaluating the reliability of distribution systems. A three-layer feedforward network with the backpropagation learning rule is constructed. The developed ANN is used to predict the distribution system reliability from the historic data. The system average interruption frequency index (SAIFI) and the system average interruption duration index (SAIDI) of a real distribution system are computed and compared with results generated by the network method. It was found that the deviation of the results computed by the proposed approach is below 1% and the required running time on a SUN network environment is less than 2 s. Handling the distribution system configuration changes induced by overloading or faults, the ANN approach demonstrates an advantage over the network method
