Topology Identification Method Based On Multi-Agent For Outage Areas In Multi-Contact Distribution Network

Distributed intelligent feeder automation (DIFA) can achieve the second level power recovery. However, it is difficult to obtain the topology information, when it applied to multi-contact distribution network. To solve the problem, this paper proposes a topology identification method based on multi-agent for outage area in distribution network. In the method, topology information is distributed in each intelligent terminal and the generation process contains three kinds of agents: internal topology publishing agent, external topology calling agent and topology generation agent, which complete the topology configuration of local intelligent terminal, topology acquisition of other intelligent terminal and topology concatenation of outage area. After the fault isolation in multi-contact distribution network, through the interaction between the three kinds of agents, the intelligent terminal generates the topology structure of outage area. The method has the advantages of clear logic and fast topology generation speed, which lay the foundation for the application of DIFA in multi-contact distribution network.
