High-power recharging pools are going to be widely deployed on the highways to guarantee a fast recharge for electric vehicles. These infrastructures may ask the grid for significant levels of power, which the grid may not be always capable to provide. In this context, stationary storage can provide peak power during the charging session, limiting the maximum power request to the grid and avoiding the need for an upgrade to the grid connection. This paper carries out the modelling and simulation of a high-power recharging pool connected to the LV distribution network and coupled with a stationary storage system. A technical-economic analysis is conducted for two different storage configurations: high-capacity storage and peak-shaving storage. Results show that the peak-shaving solution, at present, is the most convenient. In addition, it is observed that a reduced size could still support the EV recharge, with a reasonable additional waiting time, while improving the return of the investment.

Abstract
High-power recharging pools are going to be widely deployed on the highways to guarantee a fast recharge for electric vehicles. These infrastructures may ask the grid for significant levels of power, which the grid may not be always capable to provide. In this context, stationary storage can provide peak power during the charging session, limiting the maximum power request to the grid and avoiding the need for an upgrade to the grid connection. This paper carries out the modelling and simulation of a high-power recharging pool connected to the LV distribution network and coupled with a stationary storage system. A technical-economic analysis is conducted for two different storage configurations: high-capacity storage and peak-shaving storage. Results show that the peak-shaving solution, at present, is the most convenient. In addition, it is observed that a reduced size could still support the EV recharge, with a reasonable additional waiting time, while improving the return of the investment.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
