Vehicle-to-Grid for peak shaving in a Medium Voltage Grid with PV plants

Abstract

The global energy challenges impose important changes in electric energy production and transportation sectors, especially for developed countries. Today, the European road good transport sector and private mobility sector are crowded by different engine technologies which are evolving as real alternatives to internal combustion engine vehicles: in future years, an increase of electric vehicle penetration is expected. In this work, the effect of an electric vehicle fleet is simulated on a medium voltage grid, to analyze which are the effects of road transport sector electrification. A solution able to combine the batteries of electric vehicles and photovoltaic generators is proposed. Results of simulations on vehicle to grid application for peak shaving and considering profit criteria based on Day Ahead Market are discussed.
