Embodiment Construction

[0029] Such as figure 1 , figure 2 and image 3 As shown, the charging scheduling method of the electric vehicle replacement station of the present invention includes the following steps:

[0030] S1 At the end of each day, the power grid dispatching department predicts the next day's load forecast curve P Lj (j=1,2,...,24) sent to the data receiving module 1 of the charging dispatching system of the electric vehicle swapping station; at the same time, the management system of the electric vehicle swapping station calculates the total capacity of the battery in each period of the 24 periods of the next day The upper and lower limits, as well as the upper and lower limits of the charging power in each period, and the obtained data and the battery capacity at the initial moment of the next day are also reported to the data receiving module 1 of the charging dispatching system of the electric vehicle swapping station, namely: the management system of the i-th electric vehicle ...

Abstract

The invention discloses a charging scheduling method for an electric automobile battery swapping station. The charging scheduling method comprises the following steps that: S1, a scheduling department sends a next day load forecast to a scheduling system at the end of each day, and a management system calculates the upper limits and lower limits of total capacity and charging power of a battery within 24 time intervals in next day and submits the limits to the scheduling system; S2, a charging scheduling system of the electric automobile battery swapping station transmits received data to a charging scheduling model building module 2; S3, a charging power instruction calculation module calculates charging power Pij of the jth time interval of the ith battery swapping station in next day by a particle swarm intelligent optimization algorithm, and a charging power instruction output module transmits the charging power Pij of the Jth time interval of the ith battery swapping station in next day to the ith battery swapping station management system; and S4, an electric automobile power transformer management system executes charging operation according to a transmitted charging power instruction according to the battery condition in the station. By the charging scheduling method, the charging demand of the battery swapping station can be met, and the peak-load shifting effect on the power grid is realized; and the requirements of power grid running and electric automobile power transformation are coordinated.

Description

technical field [0001] The invention relates to a charging scheduling method of an electric vehicle swapping station. Background technique [0002] Facing the pressure of energy and the environment, vigorously developing electric vehicles and promoting the transformation of transportation energy has attracted the attention of the governments of China and major developed countries in the world, and all countries have increased their policy support for electric vehicles. It can be expected that a large number of electric vehicle charging loads will be connected to the grid in the future. However, the disorderly charging behavior of large-scale electric vehicles may cause the phenomenon of "peak on top of peak", increase the peak-to-valley difference of the power grid, and affect the stable operation of the power grid. [0003] Electric vehicle swap station refers to a place that uses battery replacement to provide electric energy supply for electric vehicles, and is an import...
