The balance between power supply and load demand is an important requirement for the stable operation of a microgrid.An energy coordination control strategy is presented based on a multi-agent system（MAS）under the island mode in a noncooperative environment.Considering distributed generation interests，each agent interacts and collaborates to achieve the overall goal of the system.The MAS design framework，typical distributed generation agent and load agent models，energy coordination control strategy based on priority list，and the dominant agent algorithm are proposed.An example of a particular microgrid is performed to discuss the agent behavior characteristics.The results verify that the coordination control strategy can dispatch energy flexibly in real time and ensure stable and economical operation of the microgrid.
