THE POTENTIAL FOR LOAD SHIFTING WITH FLEXIBLE EV CHARGING AT OSLO AIRPORT GARDERMOEN

Flexible charging as a load-shifting asset was explored using energy data from a parking facility with electric vehicle (EV) chargers at Oslo Airport Gardermoen (OSL) in Norway. The parking facility is an interesting candidate for flexible charging, as 60% of the charging sessions last for more than 24 hours. We investigated the potential to reduce the building’s peak load using scheduled EV charging. Monte Carlo simulations were used to model load shifting of EV charging based on historical parking data. Several scenarios were simulated, with variations in charging power, volume, duration, and the number of charging sessions. In every scenario the method successfully reduced the building’s highest loads, and in most scenarios the simulation almost completely avoided charging during the peak load hours. Overall, the study shows that there is a large amount of power flexibility in parked EVs at OSL, and that relatively simple distribution methods for charging can reduce the highest loads. Even with a larger number of charging sessions, the method used in this study would lower peak loads, although the uncertainties are greater for these scenarios.
