Charging Navigation Strategy of Electric Vehicles Considering Time-of-Use Pricing

摘要

This paper proposes a charging navigation strategy of electric vehicles (EVs) considering time-of-use (TOU) pricing, which takes into consideration both the charging demand of EV users and the revenue of EV charging station (EVCS) operators. Firstly, a spatial-temporal distribution of EVs in a day is given by a traffic simulation method. Then, by considering the impact of TOU price on charging navigation, an EV strategy including charging probability, charging energy, and charging station selection is proposed to minimize the costs of EVs. Based on the EV strategy, the optimal TOU charging price is formulated by EVCS operators to maximize the revenue under the given pricing rule. The simulation results show that the proposed method is not only beneficial to EVs and EVCSs, but also can effectively reduce the peak-valley difference of load profile and achieve the goal of peak load shifting.
