This paper presents the envisioned next generation power distribution system architecture, the so called FREEDM system. The presented system enables the plug-and-play of distributed renewable energy resources and distributed energy storage devices, therefore functions as the “energy internet”. The recent technical developments are summarized in this paper, with emphasis on the distributed grid intelligence, solid state transformer, DC microgrid, and fault isolation device. It is demonstrated that the FREEDM system is a highly attractive candidate for the future power distribution system. |
