Potential Impact of Electric Vehicles on the Electric Supply System. A Case Study for the Province of Milan, Italy

Abstract

The study analyses the impact of the electric vehicles¿ recharging activities on the electric supply system for the Province of Milan with a 2030 time horizon. In particular, the impact is seen both in terms of total electric energy consumption and in power requested to the grid. Because of the long recharging time required by the cars batteries, the probability to have thousands of cars contemporary plugged-in is not negligible.\nThe key issue of the study is a more plausible (in the authors¿ opinion) estimation of the potential electric vehicles market share evolution in the time period considered.\nThe results obtained clearly show that without an appropriate regulation (e.g. the intelligent integration of electric vehicles into the existing power grid as decentralized and flexible energy storage), electric vehicles could heavily impact on the daily requested electric power.
