Research on Sequential Charging Control Strategy Considering Charging Continuity of Electric Vehicle

Abstract

firstly, this paper establishes the disordered charging model of electric vehicle, and establishes the objective function from the perspective of safe operation of power grid to calculate the expected charging load of electric vehicle. On the premise of considering the charging continuity of electric vehicle users, the control strategy of orderly charging of electric vehicles is designed. Based on the control strategy, the charging load models of different models of electric vehicles are optimized, and the operation benefits of power grid and the economic benefits of electric vehicle users before and after optimization are analyzed. Finally, through the case analysis, it further shows that the control strategy can not only ensure the continuous charging of electric vehicle users, but also improve the power grid operation efficiency and reduce the power consumption cost of electric vehicle users, and has the effect of peak shaving and valley filling.
