A multi-agent based optimal operation for microgrid

In this paper, we propose an autonomous microgrid operation by using multi-agent approach. The proposed multi-agent system consists of seven types of agent (AG). In a microgrid, load AGs act as consumers or buyers, generator AGs, photovoltaic AGs and wind-turbine generation AGs act as producers or sellers, and battery AGs act as prosumers or sellers/buyers. In order to verify the performance of the proposed system, it applied to a simple model system with different electrical power prices. From the simulation results, it can be seen the proposed multi-agent system could perform a smart-grid operation efficiently.
