Embodiment

[0055] figure 1 It is a flow chart of the orderly charging control method for electric vehicles based on the peak-valley time-of-use electricity price of the present invention.

[0056] In this example, if figure 1 As shown, a method for controlling the orderly charging of electric vehicles based on the peak-valley time-of-use electricity price of the present invention comprises the following steps:

[0057] S1. Initialize the virtual charging station;

[0058] S2. Determine whether there is an electric vehicle connected to the charging station. When an electric vehicle is connected to the charging station, the system will automatically obtain the arrival time T of the electric vehicle b , remaining battery power SOC and total battery capacity B;

[0059] S3. The charging station requires the user to first input the estimated departure time T d and the expected power SOC at the end of charging e , the system predicts whether the electric car can reach the user's expected ...

Abstract

The invention discloses an electric automobile orderly charging control method based on a peak-valley time-of-use tariff. According to electric automobile charging characteristics and user traveling habits, the charging demand of an electric automobile is obtained through Monte Carlo simulation, an electric automobile orderly charging optimization strategy is established, a two-stage optimizationmodel with the lowest electric automobile total charging cost and the minimum power distribution network load peak-valley difference as targets is established, so that the purposes of the optimal charging cost and power grid load peak-valley difference leveling are achieved, the economical efficiency of a user and the stability of a power grid are guaranteed, finally, the two-stage optimization model is solved through erection of CPLEX based on MATLAB, the solving speed is high, efficiency is relatively high, influence of disorderly charging on the power grid is effectively reduced, and orderly charging control of the electric automobile is achieved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and more specifically relates to an orderly charging control method for electric vehicles based on peak-valley time-of-use electricity prices. Background technique [0002] In order to reduce the environmental pollution of traditional fuel vehicles and reduce the consumption of petroleum resources, electric vehicles have been developed rapidly. Electric vehicles have incomparable advantages over traditional fuel vehicles in terms of energy saving, emission reduction, and climate warming control. However, the charging locations and charging times of electric vehicles are scattered and random. With the rapid increase in the number of electric vehicles, This will inevitably have a non-negligible impact on the operation of the grid, so orderly control of charging behavior is required. [0003] Aiming at the orderly charging of electric vehicles, scholars at home and abroad have carried out...
