Coordination Control Based on Multi-agent for DC Micro-grid

In order to achieve the energy management of DC micro-grid, a multi-agent control method is proposed in this paper. The designed intelligent agent system has two layers. The lower layer agent is composed of photovoltaic power agent, wind power agent, energy storage agent and load agent. Those lower agents collect the data from field devices, and each agent analyzes the data, then the information from each agent is uploaded to the upper agent that works as center control agent. The upper agent deals with all information from each lower agent and produce control commands. Then the commands are sent to respective lower agents, and are carried out at field devices that correspond with lower agents respectively. An experiment based on JADE platform is done to verify the possibility of proposed control method. Experimental results show the designed multi-agent can realize the coordination control of the DC micro-grid.
