Abstract

AbstractThis chapter proposes a smart charging model of EVs for more efficient integration of EVs and PVs in distribution networks. The exiting EVs demand profiles of residential and public EV chargers are modified such that the existing network assets are utilized more efficiently. To study the mutual impacts of EVs and PVs penetrations as well as smart charging behavior of EVs, two cases are considered. In the first case, the EV profile is optimized without any PVs injections, while in the second case PVs impact on the network’s hosting capacity for EVs is studied. A flexibility factor is defined for EVs demand profile that can facilitate a range of modified charging profiles to realize EVs’ smart charging behavior. The model is implemented on the IEEE 69-bus MV feeder and the obtained results imply that for the modified EVs’ behavior, the existing network’s capability to supply more EV can increase significantly.KeywordsElectric vehicle (EV)Photo-voltaic (PV) generationDistribution networkEV demand profileHosting capacitySmart charging
