The distributed generation sources (DGS) offer more economic and environmental energy than traditional centralized generation. However, the loads demand for electricity can not be met simultaneously owing to the limitation of the capabilities of DGS when the microgrid is isolated from main power grid. In this paper, the method of the current power supply capacity calculating for some common micro power sources is given firstly. Thereafter, a multi-agent system based coordinated control strategy for distributed loads in microgrid is developed. When consumers need electricity, the load agent (LD Agent) is used to negotiate with distributed generation resources agent (DG Agent) whether the load can be connected to grid. When loads’ power exceeds the power supply capability, the microgrid central controller (MGCC) is used to request corresponding LD Agent to disconnect the lower grade loads according to the priorities of loads. The simulation results show that the effectiveness of the presented Multi-Agent based coordinated control strategy.
