Abstract: “This paper develops a hybrid system for solving a service restoration problem in a distribution system using genetic algorithm (GA) and expert systems (ES). The main of objective in problem of finding the optimal state of a sectionalizing switch on faults occurred is to restore as many loads as possible by transferring de-energized loads via network reconfigurations to other supporting distribution feeder without violating operating and engineering constraints. The Expert System to collect data from users. For analysis and the variables that are associated with the processing. And Genetic algorithm will process the results from an expert system modules. The feasibility of the developed algorithm for service restoration is demonstrated on distribution network with promising result.”
