Bidirectional Power Flow between EV and Grid Charge Scheduling, Optimization based on Queuing Model

Abstract: The adoption of electric cars (EVs) is projected to raise smart grid demand to meet diverse EV charging requirement. Therefore, the EV charging process at the supply station must be controlled in such a way that EV satisfaction level is increased when smart grid stability is maintained. The bidirectional power transfer between electric vehicles and the grid, i.e., Grid-to-Vehicle (G2V) and Vehicle-to-Grid (V2G), is described in this article. We capitalize on EVs’ unused electric power and offer an EV load control approach based on EV charging and discharging harmonization. A peak load management model (PLM) is proposed for scheduling EV charging and discharging services based on power demand, as well as the moment and place where each EV must be served. An Electric Vehicle Supply Equipment (EVSE) model also designed to help EVs find a charging station based on queuing theory. Finally, MATLAB simulations are used to verify and confirm the suggested approach’s efficacy.
