Charging station power distribution method, power distribution device and storage medium

Abstract

The invention discloses a charging station power distribution method, a power distribution device and a storage medium. The method includes the steps: acquiring the actual power of a transformer; judging whether the actual power exceeds the rated power of the transformer or not; calculating first power to be reduced when the actual power exceeds the rated power of the transformer; acquiring the SOC (stress optical coefficient) value and charging time T of each charging vehicle according to charging information, and calculating the reduced power of each charging pile in operation according to the SOC value and the charging time T to obtain total reduced power; judging whether the total reduced power is higher than or equal to the first power to be reduced or not; controlling the power of the charging pile in operation to be reduced according to a first preset strategy until the actual power of the transformer is lower than or equal to a preset power threshold. The load of a whole charging station on the transformer is reduced by reducing the power of the charging pile in operation, and damage to the transformer is avoided.

Description

technical field [0001] The invention relates to the technical field of power supply management of regional power grids, in particular to a power allocation method, device and storage medium for a charging station. Background technique [0002] In recent years, the number of fuel vehicles in cities has grown rapidly, and the exhaust gas of fuel vehicles has become one of the important factors for environmental problems such as urban smog and PM2.5. As a green vehicle with broad development prospects, new energy electric vehicles are being actively promoted by governments of various countries, and electric vehicles have developed by leaps and bounds. [0003] With the maturity of electric vehicle charging and swapping technology and the large-scale promotion and use of electric vehicles, the number of supporting charging equipment for electric vehicles will grow rapidly. There are two types of charging piles for household new energy electric vehicles: AC charging piles and DC...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a power allocation method, device and storage medium of a charging station to solve the problem in the prior art that the transformer load is too large during the charging peak period of the charging station, which is easily damaged and endangers the safety of the current regional power supply.
