Multiagent-based decentralized operation of microgrids considering data interoperability

Transition from conventional power distribution to active distribution networks requires extensive integration of decentralized microgrid control capabilities with on-demand industrial data interoperability. This paper presents a decentralized hierarchical microgrid operation scheme with a multiagent framework using IEC 61850 and the foundation for intelligent physical agents (FIPA) standards. The conducted studies are mainly focused on secondary and tertiary control levels. Secondary control deals with the operational reliability of the microgrid with a decentralized remote interaction between distributed energy resources (DER) and microgrid operator. Tertiary level " presents the aggregated operation of multiple microgrids aiming to enhance the reliability of the host grid with ancillary services. Experimental results are presented in a laboratory based test bed involving actual intelligent electronic devices (IED) and multiple microgrids.
