Reliability Evaluation of Active Radial Distribution Systems Based on an Improved Classification Algorithm

Authors

Abstract

This paper presents a reliability assessment algorithm for radial distribution systems such as microgrids and distributed generation units. The effects of these units and system reconfigurations on distribution system reliability can be evaluated by using the proposed algorithm. The impacts of the location and capacity of the distributed energy resources of microgrids and sectionalizing switches on reliability indices are determined. Moreover, proper location is determined by the classification of load points in distribution system. An approach to identifying the out of the service section after a fault event is presented based on the adjacency matrices. The classification of nodes is obtained by identifying different adjacency matrices based on protective devices. At last, the reliability indices of radial distribution system are calculated.
