摘要
Aiming at the fast service restoration requirement of active distribution network after fault, a self-healing service restoration system based on multi-agent technology is proposed. A hierarchical coordinated restoration mode is adopted in the system, and the regional service restoration process is initiated by the region agent of lower layer, while the conflict between the region agents is coordinated by the feeder agent of upper layer. The power balance and transfer capacity margin indexes are proposed, on this basis, the non-fault outage feeder is decomposed into several independent zones after the fault of distribution network is isolated, the self-healing system can restore service of outa-ge zone through microgrid aggregation, and utilize tie switch to transfer load of island zone, by which the service restoration can be comprehensively obtained. The voltage and current constraints of feeder are considered in the service restoration process to ensure the secure and stable system operation after fault restoration. A four-feeder distribution system with distributed generators is built in software of DIgSILENT, and the simulative results verify the feasibility and effectiveness of the proposed strategy. © 2019, Electric Power Automation Equipment Press.
