Abstract

The invention discloses charging station network connection control method and device. The method comprises the following steps: determining the voltage deviation of bus voltage of a distribution network before and after the access of different peak loads; establishing a functional relation between the deviation of the bus voltage of the distribution network and the peak loads; after receiving a network connection request, determining the bus voltage deviation after network connection according to current peak load; and if the bus voltage deviation after the network connection is less than orequal to a preset threshold, determining that the network is connected. Through the method and device disclosed by the invention, an effect of improving the grid stability at the power consumption peak of the charging station is realized.

Description

technical field [0001] The invention relates to the field of power grids, in particular to a charging station networking control method and device. Background technique [0002] The charging power of the DC charger of the fast charging station is large, and the daily load fluctuates greatly. Therefore, before the fast charging station is connected to the power grid, the voltage deviation calculation should be carried out according to the relevant regulations and according to the actual situation and related parameters. After its operation, it may be reliable for the operation of the power grid. Analysis and research on the influence of nature, and put forward technical measures to ensure the coordinated development of fast charging stations and power grids, so as to ensure the safe and stable operation of the power system after the fast charging stations are connected to the grid. [0003] The peak power of electric vehicles is very high during fast charging, and the distrib...
