A hybrid system for service restoration using expert system andgenetic algorithm

摘要

This paper develops a hybrid system for solving a servicerestoration problem in distribution systems using expert systems andgenetic algorithms. The main objective in service restoration procedureis to restore as many loads as possible by transferring de-energizedloads via network reconfigurations to other supporting distributionfeeders without violating operating and engineering constraints. Theexpert system determines switch operations to expand the supply marginof power sources in a case where the total power source capacity is notenough to restore the whole out-of-service areas. The genetic algorithmdetermines a part of out-of-service area for each power source. Thefeasibility of the developed algorithm for service restoration isdemonstrated on a distribution network with promising results
