In view of the increasing penetration rate of the distributed energy resource (DER) in the power system

while DER operated in island mode has a new effect on fault self-recovery of distribution network feeder

a multi-agent system (MAS) for fault self-recovery of distribution systems in the active distribution network (ADN) based on IEC 61850 is proposed. The MAS is composed of leader agents deployed in sectionalized switches of the feeder and member agents deployed in other components of the feeder. Based on the information model of IEC 61850

mainly the function layout and communication process between agents in the autonomous region are studied

with the fault location

isolation and supply restoration in the breakdown region accomplished through communication and negotiation between agents. The MAS not only takes into account the framework of ADN and the characteristics of load power supply in each section

but also gives considerations to the compatibility and practicality of IEC 61850 used in ADN. As illustrated in the simulation results

the proposed MAS satisfies the demand of interoperability and configurability in ADN so that the reliability and security of ADN power restoration is guaranteed. This work is supported by National Natural Science Foundation of China (No. 61170191
