Problems solved by technology

The carbon emission factor is fixed, which means that the current orderly charging does not optimize the carbon emission factor as an evaluation index. Whenever an electric vehicle is connected to the grid, its carbon emission is fixed.

Embodiment Construction

[0036] Specific examples of the present invention are given below. The specific embodiments are only used to further describe the present invention in detail, and do not limit the protection scope of the present application.

[0037] The following terms are unified as follows:

[0038] s: battery level when ready to go to charging station,

[0039] s’ : Initial charging capacity: the battery capacity s minus the power consumption on the way to the charging station,

[0040] Battery empty capacity: 1- initial charge capacity,

[0041] Extra charging power: battery empty power * charging layer genetic code%

[0042] Actual charging power: the battery power of the electric vehicle after charging is completed, that is, the additional charging power + the initial charging power.

[0043] The present invention provides a kind of electric vehicle intelligent charging method based on short-term carbon emission factor, and the steps of this method are as follows:

Abstract

The present invention is a short-term carbon emission factor-based intelligent charging method for carbon reduction of electric vehicles. The method includes the following content: linearly fitting the total carbon dioxide emissions and the total power generation of the power system in the same period of time on different days, and using the slope As the short-term carbon emission factor of the power system in the t period; based on the data of different time periods, the objective function is established with the power system load variance and carbon emissions as the optimization cost f 1 and f 2 ; When the electric vehicle is empty or turned off for more than 40 minutes, the electric vehicle is considered capable of charging, record the vehicle information of the electric vehicle that can be charged, and obtain the data set of the electric vehicle that is going to charge; obtain the data set of the electric vehicle that is going to charge The charging start time of the electric vehicle and the initial charging capacity of the electric vehicle are input, and the objective function is used as the optimization goal. The optimal charging start time and the actual charging capacity are obtained by using a double-layer non-dominated genetic algorithm.

Description

technical field [0001] The invention relates to the technical field of carbon emission and electric vehicle intelligent charging, in particular to an electric vehicle carbon reduction intelligent charging method based on a short-term carbon emission factor. Background technique [0002] In recent years, with the maturity of battery technology, electric vehicles are considered to be the most promising substitutes for internal combustion engine vehicles in the field of clean transportation. Because of zero exhaust emissions, electric vehicles can help eliminate local pollution, which is a problem in overpopulated areas. Promising importance for urban areas. However, this does not mean that electric vehicles have no environmental burden at all. The indirect carbon emissions of pure electric vehicles come from the carbon dioxide produced by the combustion and consumption of fossil energy in the grid. Large burden, and may cause more carbon dioxide emissions. Therefore, the ord...
