In recent years, automobile industries focus on the electrification and hybridization of the vehicle's production. The number of Plug in Electric Vehicles (PEV) and Plug in Hybrid Electric Vehicles (PHEV) are significantly increasing through the next years. These raises impose negative impacts on the electrical power grids. In this study, a supervision system is proposed with the aim of reducing the power losses and voltage profile improvement, thanks to a dynamic programming optimization algorithm. V2G (Vehicle to Grid) technology is introduced as benefits of vehicle electrification for electrical distribution grids.
