A Method of Restoring Distribution Systems Using Adjacent Networks and Two Levels Search

Abstract

 This paper presents an adjacent feeders search based method for service restoration of distribution systems after single faults. The developed algorithm makes a search for sections that belong to adjacent feeders and comply with two conditions: have normally open equipment installed or have a three or more derivations. As soon as the sections are selected, an exhaustive search is executed to achieve the restoration plan. To demonstrate the effectiveness of the proposed method, service restoration on a typical distribution system of Taiwan Power Company is applied. The results are compared with others approaches and show that the proposed method can provide a restoration plan very efficiently even under different load levels.
