Impact analysis of Plug-in Electric Vehicles on an electric distribution network

This paper analyzes the effect in a distribution network caused by massive recharging of Plug-in Electric Vehicles (PEV), based on a probabilistic model of consumption for PEV, which is added to the residential demand to evaluate some electrical system parameters, such as voltage levels, technical losses and maximum circuit capacity. Additionally, the behavior of the same parameters is corroborated through a sensitivity analysis, for which the PEV penetration varied between 10% and 100%. Based on these results, possible strategies to reduce the effect of the PEVs connection on safety, reliability and stability of the distribution system are proposed.
