The working efficiency of the formation vehicle-mounted power interconnection system is directly influenced by the advantages and disadvantages of the energy management method. In the face of complex application scenes, how to research an efficient energy management method of a formation vehicle-mounted power interconnection system is a critical problem which needs to be solved urgently. The Multi-Agent system (Multi-AGENT SYSTEM, MAS) is one of the hot spots of distributed artificial intelligence research and is suitable for solving decision problems in a distributed dynamic environment.

Secondly, the architecture can improve the efficiency of the formation vehicle-mounted power interconnection system. The multi-agent system can coordinate distributed power sources and loads to optimize energy consumption.
