Security of Supply with V2G Technology

The increasing adoption of electric vehicles is expected to substantially raise 
electricity demand. This could require significant grid investment to maintain secure electricity 
supply, which has traditionally been provided through infrastructure upgrades. The potential of 
smart technologies like Vehicle-to-Grid (V2G) to contribute to security of supply has prompted 
the need to quantify their impact. We hypothesize that the F-Factor methodology can 
effectively quantify V2G’s security of supply contribution. Applying F-Factor analysis to V2G 
through optimization modelling and sensitivity studies, we find that key parameters like V2G 
charger ratings, EV battery capacities, and load profile peakiness significantly influence the 
results. We conclude that the F-Factor provides a valuable tool for assessing V2G’s potential 
to enhance security of supply, with implications for more efficient grid planning in the context 
of transport electrification.
