Power distribution system, capacity sharing system, master station, sub-station, method and equipment

Abstract

The invention relates to the technical field of charging and power conversion, in particular to a power distribution system, a capacity sharing system, a master station, a sub-station, a method and equipment and aims to solve the problem how a charging facility is additionally arranged on the basis of capacity of a traditional power grid and achieve power optimization and utilization of the powergrid. The capacity sharing system comprises a terminal group, the master station and a server, wherein the terminal group comprises a first sub-station, a second sub-station and a guidance box, the master station is used for receiving power utilization data acquired by the first sub-station and a charging request acquired by the second sub-station in the corresponding terminal group ad calculatingand sending a charging instruction to the corresponding sub-station, the second sub-station is used for receiving the charging instruction of the master station and generating and issuing a control instruction to the guidance box, the guidance box is used for charging an output power of the charging facility according to the control instruction, the master station is further used for uploading charging service data to the server, and the server is used for judging a running state of a power distribution system according to the charging service data. By the capacity sharing system, electric energy sharing and ordered charging in a special region are achieved, and moreover, the system is more stable to run.

Description

technical field [0001] The invention relates to the technical field of charging and swapping, and in particular to a power distribution system, a capacity sharing system, a master station, a substation, a method and a device. Background technique [0002] With the popularity of new energy vehicles, how to effectively supply energy for new energy vehicles with insufficient energy has become the focus of attention of car owners and major manufacturers. Among them, the construction of charging facilities (such as the construction of charging piles that can provide charging power for electric vehicle batteries) is one of the mainstream solutions to solve the above problems. Taking charging piles for electric vehicles as an example, charging piles are widely installed in parking lots, residential quarters, large shopping malls, and service areas due to their small footprint, low cost, and ease of use. When using the charging pile, the user only needs to pull out the charging gun...

AI Technical Summary

Problems solved by technology

If it is necessary to build charging facilities in a centralized and large area, it is difficult to find a place that can provide corresponding power supply capacity

Even if the charging facilities are put into use, they will be limited by the rated power of the grid

This problem is particularly prominent in the existing parking lot and the charging pile expansion project of the old community: the power consumption capacity of the existing parking lot or the old community is usually planned, and the capacity cannot be increased under normal circumstances. If a large number of charging facilities are added due to the increase in capacity, it is likely to cause an impact on the power grid due to the simultaneous use of multiple charging facilities, resulting in large-scale power outages, which not only affect the daily life and normal travel of users, but also cause power outages. Frequent hair loss is also not conducive to the use of electric vehicles
