The invention provides an
electric vehicle charging station sequential charging control method based on a dynamic time-of-use
electricity price. According to the method, a charging time-of-use
electricity price preferential period is obtained through calculation according to the charging requirement of electric vehicles in a
charging station and the maximum charging load of a
power grid and is provided for clients, and whether charging is started immediately or charging is started till the
electricity price becomes lower is selected by the clients themselves so that the purpose of coordination control over sequential charging of the electric vehicles in the
charging station can be achieved. By means of the method, it is effectively facilitated that the electric vehicles in the charging
station are charged during a night valley
electricity price period, and accordingly
economic benefits of the
electric vehicle station can be improved. Meanwhile, the charging
peak load of the charging
station can be effectively controlled, and the negative effect of
electric vehicle charging on the
power grid is reduced to the maximum. A calculation model is simple, computational efficiency is high, and the requirement for hardware environment of a
control system is low; because the clients make decisions by themselves once the
electricity price is issued at one time, charging can be continuous and reliable, and the negative effect of frequent on-off of chargers in an existing sequential charging strategy on the service life of batteries and the chargers is effectively reduced as well.
