Embodiment Construction

[0033] Such as figure 1 and figure 2 Shown is an electric vehicle orderly charging control method considering new energy consumption, which is characterized in that it includes the following steps:

[0034] 1) The time-of-use electricity price mechanism is adopted to divide a day into 24 time periods by hour, and the hourly charging price is different;

[0035] 2) Update the predicted value of new energy power generation power and charging price for that period before the start of each period, and the predicted value of new energy power generation output for each period determines the charging price of electric vehicles for that period;

[0036] 3) The objective function of the optimization model is to take the minimum peak-to-valley difference of distribution network curve load and the minimum total charging cost of users as the objective function of the optimization model;

[0037] 4) Build a new energy power generation system at the charging station, and give priority to...

Abstract

The invention relates to an orderly charging control method of an electric vehicle considering new energy consumption, comprising the following steps: 1) adopting a time-sharing electricity price mechanism, dividing a day into 24 time periods according to hours, and charging prices per hour are different; 2) update that power prediction value and the char price of the new energy generation in thetime period before the start of each time period, and determining the charging price of the electric vehicle in the time period by the prediction value of the power generation capacity of the new energy generation in each time period; 3) take that minimum peak-valley difference of the distribution network curve load and the minimum total charge cost of the user as the objective function of the optimization model; 4) build a new energy generation system at that char station, giving priority to char electric vehicles with new energy sources. The purpose of the invention is to provide an electricvehicle orderly charging control method which can reduce the peak-valley difference of the electric network load and the total charge cost of the user, and is also conducive to the on-site consumption of new energy, and can effectively improve the utilization rate of renewable energy of the electric vehicle considering the consumption of new energy.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an orderly charging control method for electric vehicles considering the consumption of new energy. Background technique [0002] Insufficient fossil energy and serious environmental pollution are two major obstacles restricting social development, and fuel vehicles are the "main force" causing these two problems. Electric vehicles can replace oil with electricity, which can effectively alleviate my country's dependence on oil imports, reduce emission pollution, and improve air quality. As the number of electric vehicles continues to grow, the large-scale grid connection of electric vehicles, the lack of charging and swapping devices for electric vehicles, and their insufficient battery life bring new opportunities and challenges to the operation and control of the power grid. Moreover, electric vehicle users usually charge out of order during the peak load...
