Abstract:
Abstract: In view of the problem that the power supply capacity of most residential areas can not meet the problem of more electric vehicles charging, a method of satisfying the orderly charging control of a larger private electric vehicle in the residential district is proposed without increasing the existing power distribution capacity of the residential district. This method is based on the analysis of the history of private electric vehicles in the residential area, the law of living electricity and the historical data of residential quarters. Based on the peak-valley TOU(Time-Of-Use) tariff guidance, the control method of the electric vehicle ordered charging is carried out by using the bifurcation time. Finally, an example is used to verify the electric vehicle charging of a residential district in Lanzhou. The results show that the method can effectively reduce the peak-valley difference of the power grid load and the overload rate of the distribution network in the district, which makes the admission capacity of the electric vehicle greatly improved.
