A Multi-Agent Based Service Restoration in Distribution Network with Distributed Generations

The amount of distributed generation (DG) integrations in the distribution network is increasing. In order to enhance the service reliability, intentional islanding operation and coordinated operations of DG with supporting feeders can be considered to assist service restoration during fault. This paper presents a multi-agent based fault restoration system with and without DG assistance and compares its performance with centralized processing scheme. Network simulation results indicate that for fault detection, isolation and service restoration, a multi-agent system could outperform the centralized processing system. Equipped with adequate synchronizing equipment in the distribution system, coordinated operations of DG and supporting feeders could minimize the un-served load during fault.
