Charging control method for electric vehicles in charging station

Abstract

The invention discloses an orderly charging control method for electric vehicles in a charging station. The method comprises the steps of: building a vehicle charging model through employing the charging energy and charging price of each vehicle in each time period as the input and the charging income of each vehicle as the output; constructing a charging station model by taking the charging electricity price of each vehicle, the electricity purchasing price of the charging station and the charging energy of each vehicle in each time period as input and taking the charging income of the charging station as output; optimizing the charging station model according to a charging electricity price constraint and the balance constraint of the vehicle charging energy, and determining the optimalcharging electricity price; determining an aggregated game model of vehicle charging according to the vehicle charging model and the optimal charging electricity price; and solving the aggregation game model by using a distributed solving algorithm to determine the charging plan of each vehicle. According to the method of the invention, the aggregation game model of vehicle charging is established, the coupling relationship between the charging vehicles is processed, the optimal charging plan is made for the vehicles in the charging station, and the charging operation efficiency of the vehicles in the charging station is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle charging, in particular to a charging control method for electric vehicles in a charging station. Background technique [0002] In recent years, with the deterioration of environmental problems and the sharp decline in fossil energy reserves, new energy vehicles represented by electric vehicles have gradually attracted people's attention. According to statistics, as of 2018, the number of new energy vehicles in the country reached 2.61 million, of which the number of pure electric vehicles was 2.11 million, accounting for 81.06% of the total number of new energy vehicles; in the future, the penetration rate of electric vehicles will be further expanded , thus adding a batch of power loads at the distribution network level. The charging load characteristics of electric vehicles are different from those of traditional electricity loads: on the one hand, the distribution of charging loads of electri...

Problems solved by technology

The traditional orderly charging scheme for electric vehicles generally assumes that the charging station can fully control the charging plan of the vehicle. The car owner needs to report the arrival and departure time, as well as the charging demand and other information to the charging station. optimization; this orderly charging scheme ignores the decision-making autonomy of electric vehicle owners, and at the same time, it will lead to the leakage of private information such as the owner's driving plan. shortcoming
