Urban scale photovoltaic charging stations for electric vehicles

An energy integration between photovoltaic (PV) systems and electric vehicles (EVs) can help to overcome problems related to the feasibility of a more sustainable mobility, most of all in urban context. This paper aims to examine the potential and the technical benefits of using PV systems as energy supplier for charging EVs. For this purpose, an urban scale integrated system is presented through a mathematical model that considers the power flows related to the PV generator, the charging station, and electric grid. The most significant result is the evaluation of the self-consumption in order to optimize the interaction between the PV system and charging station for EVs. This analysis has been conducted for different vehicles typologies and different PV installations, giving rise to more than 9000 different cases and allowing to consider the wideness of the self-consumption range for different months
