Electrification of road transportation: implications for the electricity system

t is incumbent upon the transport sector to reduce its CO2 emissions by replacing fossil fuels with low-carbon alternatives. Suggested strategies include electrification of the road transport sector through the use of electric vehicles (EVs) with static charging, electric road systems (ERS), and the use of electricity to produce fuels. Electrification of the transport sector will create new electricity load profiles that depend on the time of consumption and the amount of electricity used in EVs. EVs can also contribute with flexibility to the electricity system – a feature that will be of increasing importance with a higher share of variable renewable electricity (VRE) in the electricity system. The overall aim of this thesis is to investigate how electrification of the transport sector affects the electricity system with respect to the demands for energy and power on different geographical and temporal scales. In this work, a vehicle energy consumption model is developed to estimate the variations of the energy and power demands according to time and location for the transportation work on a highway (the E39 in Norway). Furthermore, charging of passenger EVs and ERS is included in several electricity system models, to investigate how EVs influence investments in electricity generation capacity and VRE integration.
