Here we show how, based on 5G-enabled technologies, a connected power distribution grid can be split into self sufficient islands integrating self driving electric vehicles (EVs). End users form self sufficient (from the energy demand point of view) clusters called virtual power plants (VPPs), and EVs serve as energy delivery devices between different VPPs. Moreover, we show how phase-to-ground faults can be detected and isolated even in the presence of distributed energy generation, thanks to low latency communication and massive IoT.
