Experiment on distributed cooperative control with multi-agent system for a single-phase microgrid

In a microgrid, electric generation is based on combination of small generators and renewable resources such as solar and wind. The operating conditions of the microgrid are dynamically altered by both the load and the intermittent nature of the renewable resources. To maintain the voltage and frequency stability of such microgrid, this paper presents distributed cooperative control of a microgrid using multi-agent system. The multi-agent system is implemented by using Mobile-C based on Client-Server architecture, and Ch and Embedded Ch as the agents run time. Serial communication is implemented for data exchange between agents and microgrid elements. To validate the effectiveness of the proposed control system, two scenarios have been experimented. The experimental results demonstrate the generator connecting/disconnecting and load shedding ability of the microgrid.
