Towards implementation of Plug-and-Play and distributed HMI for the FREEDM system with IEC 61499

This paper presents an implementation of Plug-and-Play for the FREEDM system with IEC61499 function blocks. The FREEDM system is the envisioned next generation power distribution infrastructure which integrates DRER/ER with the legacy grid and is enabled by novel power electronics and distributed control. Plug-and-Play device integration is one of the key features of the FREEDM system that allows distributed renewable energy resources and distributed energy storage devices to be added or removed from the FREEDM distributed intelligent devices seamlessly. IEC61499 is an open standard for designing distributed control systems, which is investigated in the FREEDM project as an underlying system-level software architecture. Plug-and-Play is achieved by dynamic reconfiguration in IEC61499 to create the necessary function blocks during runtime for enabling Plug-and-Play between the DRER and the DGI devices. The developed Plug-and-Play technology is incorporated into the FREEDM infrastructure implemented in IEC61499 function blocks.
