Service Restoration Strategy of Distribution Network Based on Multi-agent and 5G Communication Technology

Multi-agent technology is widely used in the protection and control of distribution network because of its decentralized coordination advantages, but it is limited by communication conditions and cannot be widely promoted in distribution networks where the fiber optic laying rate is not high. With the in-depth research and commercial emergence of 5G, it gives a broad prospect for the application of multi-agent technology in distribution networks. In this paper, a service restoration strategy of active distribution network based on 5G wireless communication and multi-agent technology is proposed. The multi-agent system consists of a hierarchical coordination control model consisting of Feeder Agent (FA) and Region Agent (RA). The information is transmitted using 5G communication channel. Each RA designed with suitable control architecture can implement restoration, which guarantees the celerity of restoration. By building a 4-feeder system with distributed power on PSCAD, the feasibility and effectiveness of the proposed strategy in this paper are verified.
