Method and system for dynamically regulating and controlling power supply capacity of charging pile and related equipment

Abstract

The invention discloses a method and system for dynamically regulating and controlling the power supply capacity of a charging pile and related equipment. The method comprises the steps: acquiring an inputted regional power supply capacity parameter of a corresponding management region, and monitoring the operation parameters of a distribution network area to obtain real-time monitoring data; and according to the regional power supply capacity parameters and the real-time monitoring data, acquiring a required power supply capacity value of the charging pile cluster, and according to the required power supply capacity value, regulating and controlling the output power of charging piles. According to the method, the adjustability of the energy type load of the new energy automobile is applied, and active and dynamic power supply capacity regulation and control are performed on the charging pile cluster according to the power supply capacity of the distribution network area and the load of the corresponding management area, so that the problems of distribution transformation and line overload and the like can be effectively avoided, safe operation of a power grid is guaranteed, the distribution network construction investment is reduced, the charging facility access capability and the use efficiency of the distribution network are improved, and the stable operation of the distribution network is ensured.

Description

technical field [0001] The invention belongs to the technical field of charging of new energy vehicles, and in particular relates to a method, system and related equipment for dynamically regulating and controlling 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 shown a continuous high-speed growth trend. After the number of new energy vehicles increases to a certain proportion, most of the charging points of vehicles will be charged by public The point is transformed into a residential area or an office area to complete charging. [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 protec...

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.
