Plug-in electric vehicles are the currently favoured option to decarbonize the passenger\ncar sector. However, a decarbonisation is only possible with electricity from renewable energies and\nplug-in electric vehicles might cause peak loads if they started to charge at the same time. Both of\nthese issues could be solved with coordinated load shifting (demand response). Previous studies\nanalysed this research question by focusing on private vehicles with domestic and work charging\ninfrastructure. This study additionally includes the important early adopter group of commercial fleet\nvehicles and reflects the impact of domestic, commercial, work, and public charging. For this purpose,\ntwo models are combined that capture the market diffusion of electric vehicles and their charging\nbehaviour (ALADIN), as well as the load shifting potential of several new energy technologies\n(eLOAD). In a comparison of three different scenarios, we find that the charging of commercial\nvehicles does not inflict evening load peaks in the same magnitude as purely domestic charging of\nprivate cars does. Also, for private cars, charging at work occurs during the day and may reduce the\nnecessity of load shifting while public charging plays a less important role in total charging demand\nas well as load shifting potential. Nonetheless, demand response reduces the system load by about\n2.2 GW or 2.8% when domestic and work charging are considered when compared to a scenario with\nonly domestic charging where a new peak might be created in the winter hours due to load shifting\ninto the night.
