Charging Control Strategy to reduce the remaining capacity of electric buses

In order to solve the electric buses remaining excess capacity at the end of work and the economic operation problems of the power grid, the too large load and the higher harmonic content during the noon to complement the power collectively. In this paper the electric bus charging station is the study object, analyzes the negative effect on the gird due to the too much electric buses remaining battery, present a charging control policy to reduce the remaining battery of electric buses depending on the TOU (time of use) and the running characteristics of bus charging stations. The simulation based on practical cases indicated that the policy can be a good way to decrease the remaining battery at the end of work, reduce the grid maximum load and cut the cost of the bus charging station.
