Nowadays the continuously increasing scale of grid connection of charging electric vehicles has brought changes to load composition and characteristics of distribution networks and new challenges to the conventional grid planning prin-ciples.This paper proposes a probabilistic analysis method to study the influence of grid connection of charging load on dis-tribution transformer through characteristic curve fitting.This method may provide new inspiration for handling the pa-rameter changes of distribution networks caused by large-scale grid connection of charging electric vehicles,and facilitate the adjustment of conventional grid planning strategies for higher adaptability.
