Electrical vehicle charging strategy for electric road systems considering V2G technology

The accelerated adoption of electric vehicles (EVs) introduces a substantial amount of load to the power grid. The electric road system (ERS) emerged as a promising solution to decarbonize heavy good vehicles and extend the driving range of EVs, will further complicate the operation of power grid. Therefore, optimal scheduling of EV charging in ERS is vital in minimizing the impact of variable EV loads to the power grid that provides power supply to the ERS. This paper proposes a charging strategy based on load floating (LOF) electricity price. The approach divides a day into different time periods, counting the grid-connected and off-grid time of vehicles, and then establish dispatching and charging cost models, based on which the EV charging cost is minimized. The simulation results confirm the efficiency of the proposed scheduling strategy.
