Distributed Restoration system applying Multi-Agent in distribution automation system

Abstract

In this paper, as make up for the weak points of the centralized restoration in DAS, distributed restoration method applying multi-agent is proposed for increasing the efficiency and saving time of the restoration time of blackouts. Distribution restoration method is difficult to deal with a fault quickly because DAS manage, judge and order the states of distribution network after gathering all information from FRTUs when the fault occurs. If Feeder Remote Terminal Unit (FRTU) in distribution network performs restoration and separates minimized fault section itself by exchanging information using communication to each other, the efficiency and time of the restoration can be enhanced by much. In the case studies, this paper is proposed a distributed restoration method which can make up the weak points of the centralized restoration in DAS by converting FRTUs into multi-agents. The proposed method has been testified in Gochang power test field in Korea and the result in the restoration shows its performance.
