Embodiment 1

[0088] An orderly charging scheduling method based on electric vehicle charging load forecasting, such as figure 1 shown, including the following steps:

[0089] A) Obtain the probability density curve of the daily mileage of the electric vehicle and the probability distribution function of the initial charging time through statistics, calculate the initial state of charge probability curve when the electric vehicle is charged, and obtain the charging time required by combining the charging power of the electric vehicle.

[0090] The probability density curves and initial charging time probability distribution functions of electric private cars, electric taxis, and electric buses are respectively counted and obtained.

[0091] B) Obtain the daily charging load curve of the electric vehicle according to the probability distribution function of the initial charging time, the initial state of charge probability curve, and the charging power.

[0092] According to the characteris...

Abstract

An ordered charging scheduling method based on electric vehicle charging load prediction comprises the following steps: A) calculating an initial state-of-charge probability curve when an electric vehicle is charged, and obtaining a time length required by charging in combination with the charging power of the electric vehicle; B) obtaining a daily charging load curve of the electric vehicle; C) taking the minimum charging cost of the user side and the minimum load peak-valley difference of the power grid side as objective functions, and establishing an electric vehicle ordered charging optimization model in the district; D) calculating the optimal solution of the objective function of the orderly charging optimization model of the electric vehicles in the area under the constraint condition, and taking the optimal solution as a charging scheduling method. The invention has the substantive effect that the electric vehicle charging load prediction model is established on the basis of detailed research on the charging load characteristics of various electric vehicles. The minimum charging cost of the user side and the minimum load peak-valley difference of the power grid side are taken as an objective function, an electric vehicle ordered charging optimization model is established in the district, and the objective function is solved to obtain the optimal ordered charging scheduling method.

Description

technical field [0001] The present invention relates to the field of charging scheduling, in particular to an orderly charging scheduling method based on electric vehicle charging load prediction. Background technique [0002] With the increasing penetration of electric vehicles, the charging load of electric vehicles has gradually become an important load in the regional power grid. Due to the randomness of electric vehicle charging load in time and space, its access to the grid will inevitably have a certain impact on the grid. In view of the phenomenon of "peak-on-peak" load caused by the disorderly access of electric vehicles, real-time electricity prices are adopted to encourage charging behavior, and the charging sequence of each user is reasonably arranged, so that electric vehicle users can complete charging as much as possible during the low-load period. .
