Problems solved by technology
However, due to the limited capacity of the charging station, all the charging piles in the charging station will output full power at the same time, and the operating power of the grid-connected point output by the charging station will exceed the limit value, which will easily lead to the failure of the charging station. The transformer is overloaded, overheating and voltage fluctuations will affect the stable operation of the charging station, and may even lead to serious charging failures and other major safety issues

The present application relates to a power control method, device, computer equipment and storage medium of a charging pile. The method includes: acquiring the current operating power of the charging station and the current operating power of the charging piles in the scheduling set; if the current operating power of the charging station is greater than the preset maximum charging power, then determining the current operating power Determine the overpower of the charging station by the difference between the maximum charging power of the charging station; obtain the remaining charging power of the electric vehicles connected to each charging pile, and determine the remaining charging power proportion of each electric vehicle; according to the remaining charging power proportion of each electric vehicle and The product of the overpower of the charging station determines the power adjustment amount of each corresponding charging pile; according to the difference between the current operating power of each charging pile and the power adjustment amount, the target operating power of each charging pile is determined; The charging pile performs power control. By adopting this method, the operating power of the grid-connected point of the charging station is prevented from exceeding the limit value.
Description
technical field [0001] The present application relates to the technical field of system power control, and in particular, to a power control method, device, computer equipment and storage medium of a charging pile. Background technique [0002] Against the background of increasingly tight environmental protection and energy supply, the electric vehicle industry in the field of new energy has developed rapidly. As the use of electric vehicles is increasing on a large scale, my country needs to build or expand a large number of electric vehicle charging stations to meet the charging needs of electric vehicles, resulting in the construction speed of charging stations is much higher than the construction speed of the power grid system. Under the circumstance that the existing power capacity is limited, the charging safety of electric vehicles has become an important consideration in the construction of electric vehicle charging stations. [0003] At present, my country mainly s...
