Multi-agent based distributed control architecture for microgrid energy management and optimization

• A new multi-agent based distributed control architecture for energy management.
• Multi-agent coordination based on non-cooperative game theory.
• A microgrid model comprised of renewable energy generation systems.
• Performance comparison of distributed with conventional centralized control.

Most energy management systems are based on a centralized controller that is difficult to satisfy criteria such as fault tolerance and adaptability. Therefore, a new multi-agent based distributed energy management system architecture is proposed in this paper. The distributed generation system is composed of several distributed energy resources and a group of loads. A multi-agent system based decentralized control architecture was developed in order to provide control for the complex energy management of the distributed generation system. Then, non-cooperative game theory was used for the multi-agent coordination in the system. The distributed generation system was assessed by simulation under renewable resource fluctuations, seasonal load demand and grid disturbances. The simulation results show that the implementation of the new energy management system proved to provide more robust and high performance controls than conventional centralized energy management systems.
