The Optimal Charging Strategy of EV Rational User Based on TOU Power Price

This paper deals with the optimal charging strategy of electrical vehicle (EV) rational user with different time and mileages based on time-of-use (TOU) power price. Four types of EV response model are established and the optimal charging strategy of rational user is given based on five period of charging price and three period of discharging price. Under the price, the paper calculates charging, load and network loss. The power load and network loss are calculated to ensure the superiority of the proposed strategy. The simulation results show that the optimal charging strategy proposed not only reduce the cost of EV users but also reduce the power network loss rate. It achieves the win-win goal of EV users and electric power company.
