The present application discloses a charging control method, system and device for an electric vehicle charging station, including: by obtaining the historical daily load of the transformer and the historical daily load of the charging station, and predicting according to the historical daily load of the transformer and the historical daily load of the charging station, the transformer is obtained Forecast daily load and charging station forecast daily load, substituting the transformer forecast daily load and charging station forecast daily load into the preset formula to obtain the planned daily load of the charging pile, control the electric power of the charging pile according to the planned daily load, and judge whether the real-time total load of the transformer is is greater than or equal to the first threshold, if so, reduce the real-time total load of the transformer to the second threshold, otherwise perform the above steps again. It solves the technical problem that the charging load of the existing electric vehicle charging station is superimposed with the traditional peak load of the power grid due to disorderly charging, resulting in the shortage of power consumption in some areas and the unbalanced load of the distribution network.
Description
technical field [0001] The present application relates to the technical field of charging management, and in particular to a charging control method, system and device for an electric vehicle charging station. Background technique [0002] The construction of electric vehicle charging infrastructure is the basis for the strategic development of electric vehicles in my country. With the rapid increase in the charging power of electric vehicles, the demand for grid expansion in the construction of charging facilities shows a trend of disorderly growth. How to realize the power users and grid companies through orderly charging? The win-win benefit has become a major technical challenge. [0003] At this stage, the large-scale access of charging pile electric vehicles directly leads to the rapid growth of grid load, and due to disorderly charging, the charging load is superimposed on the peak period of traditional grid load, which further aggravates the peak-valley difference of ...
