Abstract

The invention relates to an orderly charging system and method for an electric taxi charging station, and belongs to the field of intelligent power grid control. The system is composed of a battery management system, a batter charger, a charging point, an SCADA (supervisor control and data acquisition) system/a PQ (performance quality) monitoring system, an orderly charging control center and a batter charging information database. According to the background load of a to-be-predicted power grid and the demand on the charging power of an electric taxi, the optimal charging start time and the optimal charging phase plan are formulated for each electric taxi, and the electric power of the power grid at a valley period is fully utilized for charging a power battery of the electric taxi, so that the load of a superior transformer substation can be adjusted, the difference between the peak and the valley can be relieved, the load fluctuation of the power grid can be restrained, and the economy and the efficiency of the power grid are improved. Meanwhile, according to the single phase charging manner of the taxi, the optimal charging phase can be selected via the system, so the unbalance of the three-phase load can be reduced.

Description

Technical field [0001] The invention relates to an orderly charging system and method for an electric taxi charging station. The invention belongs to the field of smart grid control. Background technique [0002] With the implementation of the government's 1,000-vehicle project in ten cities, the number of electric vehicles has increased substantially. The operating cost of electric taxis is lower than that of petrol vehicles, and it has become a trend in the taxi industry to use electric vehicles to replace petrol vehicles. As an adjustable load, the charging load of the electric taxi battery can smooth the fluctuation of the grid load, and orderly charging can avoid the large-scale impact of centralized charging on the grid after the large-scale electric taxi. [0003] The difference between the charging load of the power battery of an electric taxi and other electric loads lies in the difference between the time it takes to connect to the grid and the actual charging time, whic...
