Smart charging of electric vehicles in buildings and electricity networks in focus in new licentiate thesis


On 15 October, Reza Fachrizal at the Division of Civil Engineering and Built Environment presented his licentiate thesis on how smart charging of electric vehicles connected to residential buildings can increase the buildings' self-consumption of photovoltaic (PV) power and at the same time enable increased connection of both charging infrastructure and PV systems to electricity networks.

Smart charging of electric vehicles means that the times for when charging begins and ends are chosen to achieve some type of goal, for example as low charging cost as possible. Reza's thesis investigated how electric vehicle charging can be optimally scheduled to times when the on-site generation of PV power is highest, both to increase the self-consumption of PV electricity in buildings and to reduce the load on the electricity networks.

The results from the thesis show that the PV self-consumption in the studied residential buildings could increase by up to 9% and that the peak power demand could be reduced by half. Smart charging also reduces losses and voltage variations in the electricity networks, which means that more electric cars can be connected without the need for grid reinforcement in residential areas.

Reviewer of the dissertation and discussion leader at the seminar was Pei Huang, postdoc in Energy Engineering at Dalarna University with a PhD from City University of Hong Kong.

The licentiate thesis, titled Synergy between Residential Electric Vehicle Charging and Photovoltaic Power Generation through Smart Charging Schemes: Models for Self-Consumption and Hosting Capacity Assessments, can be read in its entirety here.
