ABSTRACT: Microgrid systems are built to integrate a
generation mix of solar and wind renewable energy resources that are generally
intermittent in nature. This paper
presents a novel decentralized multi-agent system to securely operate
microgrids in real-time while maintaining generation, load balance. Agents provide a normal operation in a grid-connected mode
and a contingency operation in an islanded mode for fault handling. Fault
handling is especially critical in microgrid operation to simulate possible
contingencies and microgrid outages in a real-world scenario. A robust agent
design has been implemented using MATLAB-Simulink and Java Agent Development Framework technologies to simulate
microgrids with load management and distributed generators control. The
microgrid of the German Jordanian University has been used for simulation for
Summer and Winter photovoltaic generation and load profiles. The results show
agent capabilities to operate microgrid in real-time and its ability to
coordinate and adjust generation and load. In a simulated fault incident,
agents coordinate and adjust to a normal operation in 0.012 seconds, a
negligible time for microgrid restoration. This clearly shows that the
multi-agent system is a viable solution to operate MG in real-time.
