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 invention relates to an electric vehicle carbon reduction intelligent charging method based on a short-term carbon emission factor, and the method comprises the following steps: carrying out the linear fitting of the total carbon dioxide emission in the same time period of different days and the total power generation amount of a power system, and taking the slope as the short-term carbon emission factor of the power system in the t time period; establishing objective functions f1 and f2 by taking the data of different time periods as the basis and taking the load variance and the carbon emission of the power system as optimization cost; when the electric automobile is in an empty or flameout state for more than 40 minutes, the electric automobile is considered to be capable of being charged, information of the electric automobile capable of being charged is recorded, and a data set of the electric automobile going for charging is obtained; the charging starting time of the electric vehicle data set to be charged and the charging initial electric quantity of the electric vehicle are obtained, the charging starting time and the charging initial electric quantity serve as input, the target function serves as an optimization target, and the optimal charging starting time and the actual charging electric quantity are obtained through 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...
