In order to manage electric vehicles (EVs) connected to charging grids, this paper presents an orderly charging approach based on the EVs'' optimal time-of-use pricing (OTOUP) demand response. Firstly, the Monte Carlo approach is employed to anticipate charging power by developing a probability distribution model of the charging behavior of …

Electric vehicles can effectively make use of the time-of-use electricity price to reduce the charging cost. Additionally, using grid power to preheat the battery before departure is particularly important for improving the vehicle mileage and reducing the use cost. In this paper, a dynamic programming algorithm is used to optimize the battery AC …

It can be known from Section 3.1 that T start, d is the start time of TOU price valley time on day d and T start, d +1 is the start time of TOU price valley time on day d + 1. When the sun rises early in the summertime morning ( T rise, d < T end, d ), the power grid is still in valley time but the sunlight intensity had reached a high-level already.
