Deterministic and probabilistic assessment of the impact of the electrical vehicles on the power grid

This paper analyzes the impact of charging of EVs (Electrical Vehicles) on a MV power grid. In order to simulate the behavior of the EV charging a battery model has been used to model the EV's charging curve. As the way how EV is charged from the grid affects critically to the voltage levels and to the saturation of the lines, two modalities of charging are presented: not-controlled charging and controlled charging. Finally, the simulations have been performed from two points of view: deterministic analysis and probabilistic analysis.
