Technical and environmental impact of electric vehicles in distribution networks

Against the background of raising C0 2 emissions, there is a great interest in electric vehicles (EVs) as replacement for internal combustion engine vehicles (ICEVs). This paperassessesthe CO 2 reduction in the UK result from EVs for years to 2030 based on two factors: future carbon density of different power generationmix in the UK driven by energy policy; and projected EV penetrations; in order to illustrate theimportant role that EVs play in the UK commitment emissions reduction targets. The battery charging of EVs will adds an extra burden on distribution networks, which may cause peak demand, voltage drop, cable thermal overloads and increase in loss. The technical impacts of EVs charging in 2030 are analyzed at residential distribution level. The possible solutions includingdemand side participation is considered to evaluate large scale integration of EVs.
