Reliability Evaluation of Pilot Virtual-Mesh FREEDMSs by SST Series and Three-Port Power Hub Parallel Energy Routers

Integrating FREEDMS and an energy router help overcome the variability and intermittency of renewable resources for energy Internet development. Due to the developed information technology interconnection approach, energy routers are expanding with more and more multi-port topologies, which can be considered as a point-to-point connection approach. In this paper, another connection approach is proposed. On the other hand, recently, SST (series) and three-port power hub (parallel) approaches as energy routers for FREEDMS have been getting more and more attention. However, the existing literature focusing on the reliability of FREEDMS infrastructures still needs to be addressed. The FREEDMS infrastructure enhances the smart grid's reliability and resilience to support power to communities, so its reliability evaluation is critical to determine its superiority. This paper addresses and compares the reliability evaluation of existing energy routers by SSTs and Three-Port Power Hubs. Instead of series one, the Pilot Virtual-Mesh FREEDMS infrastructure and a parallel energy router approach are proposed.
