目前电动汽车接入电网充电的规模越来越大,使得配电网负荷组成及其特性发生变化,因此对传统的常规电网规划策略提出新挑战.对此,提出概率性分析方法,通过特性曲线拟合,研究充电负荷接入对配变的影响,为解决大规模电动汽车接入电网充电所带来的配电网相关参数变化问题提供了新思路,有助于传统电网规划进行更具适应性的策略调整.
Method of Analyzing the Influence by Connection of Charging Load to Distribution Transformer in Typical Scenarios
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.
