3. Evaluation and variability of power grid hosting capacity for electric vehicles : Case studies of residential areas in Sweden
Abstract : Electric vehicles (EVs) are increasing in popularity and play an important role in decarbonizing the transport sector. However, a growing EV fleet can cause problems for power grids as the grids are not initially designed for EV charging. The potential of a power grid to accommodate EV loads can be assessed through hosting capacity (HC) analysis. READ MORE
