Impact of Electric Vehicles on an Unbalanced Distribution Grid with Renewables


Electrification of transportation1 is one of the main drivers for carbon reduction in modern societies. Most countries today are providing incentives for the replacement of conventional ICE cars with electric or hybrid ones.

These cars will be hosted in the existing Distribution Networks (DNs) and might cause severe issues related to congestion and power quality. If these problems are not analysed and addressed, the penetration of EVs will be hindered and delayed.


In this project, you have to analyse the impact of EVs on an unbalanced distribution network with increased penetration of renewables2. This will involve understanding the structure of DNs and their limitations, modeling of different power components, and analysing power quality issues. Moreover, you will need analyse the impact of different combinations through a stochastic method to account for uncertainty. Some references are 3 and 4.

This project requires excellent programming and analytical skills. It is in collaboration with EAC.
