A method, system and related equipment for dynamically regulating the power supply capacity of a charging pile

Abstract

The invention discloses a method, a system and related equipment for dynamically regulating the power supply capacity of a charging pile, wherein the method comprises: acquiring the entered regional power supply capacity parameters corresponding to the management area, and monitoring the real-time monitoring of the operation parameters of the distribution network station area. According to the regional power supply capacity parameters and the real-time monitoring data, the required power supply capacity value of the charging pile cluster is obtained, and the output power of the charging pile is regulated according to the required power supply capacity value. This application applies the controllability of the energy-based load of new energy vehicles, and actively and dynamically controls the power supply capacity of the charging pile cluster according to the power supply capacity of the distribution network station area and the load of the corresponding management area, which can effectively avoid the distribution transformer and line overload. To ensure the safe operation of the power grid, reduce the investment in the construction of the distribution network, improve the ability and efficiency of the distribution network to access charging facilities, and ensure the smooth operation of the distribution network.

Description

technical field [0001] The invention belongs to the technical field of charging of new energy vehicles, and in particular relates to a method, a system and related equipment for dynamically regulating the power supply capacity of a charging pile. Background technique [0002] With the development of quality of life and technology, in recent years, the percentage of new energy vehicles in the total number of vehicles has continued to grow rapidly. After the number of new energy vehicles increases to a certain proportion, most of the charging points of vehicles will be charged by the public. The point is transformed into a residential area or office area to complete the charging. [0003] The charging demand of a large number of new energy vehicles will cause huge pressure on the power supply load of the distribution network. The large-scale charging load and the residential electricity load are superimposed, and the existing distribution network is difficult to carry, which w...

AI Technical Summary

Problems solved by technology

[0003] The charging demand of a large number of new energy vehicles will put a huge pressure on the power supply load of the distribution network. The large-scale charging load will be superimposed on the residential electricity load. Power outages caused by overload protection in the residential distribution network, or more serious transformer damage, causing more serious safety risks and economic losses

[0004] The existing solutions are adding transformers or power distribution rooms, but the cost of building a new system is too high; or planning and constructing charging piles according to the remaining capacity of power distribution in the community, which cannot fundamentally solve the problem of overload

[0005] Therefore, how to effectively solve the problem that the line is easily overloaded when the charging demand of new energy vehicles is large needs to be solved urgently.
