Charging station load control system, method and device and computer storage medium

Abstract

The invention discloses a charging station load control system, method and device and a computer storage medium. A charging scheduling cloud platform acquires charging power output by each charging pile and acquires outgoing line total power data of a distribution transformer or a distribution network total load switch through a distribution controller, and generates an adjusting signal to adjustthe charging pile, so that the total output power of all the charging piles is changed according to the change of the outgoing line total power data of the distribution transformer or the distributionnetwork total load switch, thereby not only being capable of avoiding operation safety accidents such as tripping and even burnout of the total load switch, but also being capable of solving the problem that the charging station cannot utilize the peak-valley idle power of the power distribution network, realizing large-power charging output of a large number of charging piles. Excessive investment of power distribution assets is avoided, economic and efficient operation of the charging station is further realized, the investment return period of the charging station is shortened, and the investment return rate of the charging station is improved.

Description

Technical field [0001] The present invention relates to the technical field of negative control, in particular to a charging station load control system, method, device and computer storage medium. Background technique [0002] As an important national development strategy, electric vehicles have now been applied to the lives of the general public. Electric vehicle charging piles, especially DC fast charging piles, are widely distributed in various parking lots as an important infrastructure for the popularization of electric vehicles. Electric vehicle charging piles are high-power electrical equipment. The capacity of ordinary civilian or commercial transformers cannot meet the requirements of multiple charging piles at the same time, and the regional grid power distribution capacity is limited or there is peak, flat and valley power, and there is a large amount of idle power in the valley section. In the peak section, the idle power is very small and difficult to use. Therefore...

AI Technical Summary

Problems solved by technology

Electric vehicle charging piles belong to high-power electrical equipment. The capacity of ordinary civilian or commercial transformers cannot meet the simultaneous charging of multiple charging piles, and the regional power grid distribution capacity is limited or there is peak and valley power, and there is a large amount of idle power in the valley. The idle power in the peak section is very small and difficult to use. Therefore, in order to meet high-power charging, it is necessary to provide sufficient distribution network capacity, resulting in high investment costs for existing charging stations and a small number of stations or charging piles.
