The application of multi agent system in microgrid coordination control

Microgrid, a new type of power-supplying mode, has promising future. But it can hardly be controlled in a traditional way due to its distributed characteristics and considerable control capabilities over the network operation. In order to solve this problem and improve the efficiency and reliability level of Microgrid, a Multi Agent-based control framework is originally presented in this paper. A three-layer Multi Agent System (MAS), including main grid agents, Microgrid agents and component level agents, is established based on the proposed hierarchical coordinated control strategy. Thereafter, an agent control model, aiming at maximum efficiency of MAS, is introduced under the premise of MAS´s voltage stability and power balance. Accordingly, the special functions and control strategies of each agent are discussed in details as well. A simulation example of a particular Microgrid is performed to demonstrate the effectiveness of MAS.
