Abstract

Electrifying the transportation sector helps reducing carbon emissions. However, the need of electric vehicle to receive charging from the power grid introduces various technical impacts to the grid operation. This paper presents a comprehensive investigation of technical impacts of electric vehicle charging to Malaysian distribution grid. The charging assessment considered different power grid loadings, electric vehicle charger types, electric vehicle charging locations, and electric vehicle charging times. These factors were taken into considerations to ensure the practicality of the study. The technical impact study was implemented in a typical Malaysian distribution grid under four different scenarios with respect to the interconnection schemes outlined in the Technical Guidelines for Interconnection of Electric Vehicle to Distribution System. The studies were performed using Matlab/Simulink software. The results indicated that the charging of electric vehicles in Connection Schemes I, II, and III caused overloading of cables and substation transformer, whereas DC fast charging in Connection Scheme IV caused severe grid voltage violation.

电动汽车充电对马来西亚配电网的技术影响评估

电气化运输部门有助于减少碳排放。然而，电动汽车需要接受电网充电，这给电网运行带来了各种技术影响。本文全面研究了电动汽车充电对马来西亚配电网的技术影响。充电评估考虑了不同的电网负荷、电动汽车充电器类型、电动汽车充电地点和电动汽车充电时间。考虑到这些因素，以确保研究的实用性。这项技术影响研究是在一个典型的马来西亚配电网中，根据《电动汽车与配电网互联技术指引》中概述的四种不同的互联方案进行的。研究采用Matlab/Simulink软件进行。结果表明，方案一、方案二、方案三的电动汽车充电造成电缆和变电站变压器过载，方案四的直流快速充电造成电网电压严重超标。
