Distribution system restoration using fuzzy multi-criteria evaluation

This paper presents algorithm for distribution system restoration of out of service area after the identification of fault and isolation of faulted area. Power system restoration is multiobjective, multi constraint problem so various objectives like minimization of switches, minimization of maximum loading among laterals and feeders has been studied. Various restoration plans are obtained after switching operations and simple numerical operations followed with fuzzy multicriteria evaluation. To demonstrate the proposed algorithm a typical distribution system of Taiwan Power Company was examined.
