Multi-agent Distributed Cooperative Control of Multi-energy Complementary Microgrid

With the increasing use of distributed energy, the concept of microgrid has been proposed and used to coordinate the management of single distributed energy and load. For the large grid, the microgrid is represented as a single manageable unit, which meets the reliability and security requirements of customers. The microgrid can be connected to the power grid or disconnected from the main power grid, and operates in island mode in case of grid failure or need. Therefore, it is very important to ensure the power quality in the island microgrid. However, few people have studied multi-agent distributed cooperative control of multi-energy complementary microgrid (MECM for short here), so this paper focused on this topic. Firstly, this paper introduced the MECM and microgrid control mode, then analyzed the multi-agent system, and then discussed the distributed generation and distributed management control system. At the end of this paper, the multi-agent distributed cooperative control of building MECM was analyzed, and the feasibility conclusion was drawn. In the micro-grid scenario of load change in grid-connected operation mode, this paper simulated the coordination and scheduling process of each agent layer and found that the coordination control system proposed in this paper had great stability. In the island operation mode, the multi-agent distributed cooperative control system based on MECM can well adapt to the sudden change of microgrid load even in the autonomous operation. The power of micro-source without radio wave change was maintained at 80kW. At present, microgrid had a relatively wide application space, and also had a relatively broad application prospect in the development of collaborative control system.
