Research on EV Ordered Charging Considering TOU Price

Large-scale of electric vehicles (EVs) for charging will affect grid operation, disordered charging will have significant impact on the grid. This paper presents ordered charging mathematical model considering the smallest charging fees for EV users, a genetic algorithm is used to get optimization solutions. Monte Carlo method is used to simulate EV charging user behavior, analysis of disordered and ordered charging simulation results are compared under different charging mode. Simulation results show that ordered charging has huge roles in reducing the cost of user charge, reducing the peak-valley difference, improving load stability and users satisfaction. The results of example show the rationality of this model and algorithm.
