Electric Vehicle Charger Static and Dynamic Modelling for Power System Studies

Electric Vehicles (EVs) are becoming increasingly available and expected to be a large part of the load in future power systems. EV chargers relatively new type mainly interfaced with grid through electronics. It is therefore important investigate impact they have on system dynamic behaviour. In this paper, two detailed charger models (representing typical slow fast charger) were investigated. The aim was test capability standard static—and more importantly, dynamic—load models, commonly used studies, represent static behaviour chargers. Different control parameter settings for types investigated, as limits model structures’ accurate representation. Typical sets also been provided cases where proper representation possible.
