Abstract:

Electric vehicles provide a significant opportunity for reducing the consumption of fossil energy and the emission of carbon dioxide. With more and more electric charging facility integrated in the power systems， the impact on the power system distribution network and power quality cannot be ignored now. This paper analyzes the typical mode of charging infrastructure integrating to the distribution network，the prediction of the power demand and power load of the charging infrastructure， and the acceptance ability of power grid. The influence of charge load in different scenarios is analyzed， including residential areas， public parking， exclusive bus stations and exclusive taxi stations， and then the principles of power grid construction planning are proposed， which will provide references to large-scale electric vehicle charging facility integrating to distribution network.

Key words: electric vehicle, charging infrastructure, charging load, distribution network
