The purpose of this work is to evaluate the energy impact on the distribution network at the point of connection of an electric plant of a railway car park where some charging points for electric vehicles have been installed.

Scopo del presente lavoro è valutare l’impatto energetico apportato alla rete di distribuzione nel punto di allaccio dell’impiato elettrico di un parcheggio ferroviario nel quale sono stati predisposti alcuni punti di ricarica per veicoli elettrici. La prima parte presenta una summa circa l’attuale stato di sviluppo della mobilità elettrica, descrivendo le varie tipologie di veicoli elettrici, le infrastrutture di ricarica e le possibili applicazioni nelle Smart Grid. Nella seconda parte, invece, viene simulata una possibile curva di carico del parcheggio in esame e, sul principio della tecnologia Vehicle-to-Grid, è stato messo a punto un opportuno algoritmo che, sfruttando la possibilità di un flusso energetico bidirezionale tra i veicoli parcheggiati e la rete elettrica, va a ribilanciare la curva di carico dell’impianto sotto esame al fine di evitare pericolosi picchi di assorbimento, di norma difficilmente gestibili dal DSO. Il lavoro presenta anche l’accoppiamento con un impianto fotovoltaico progettato ad hoc per il parcheggio.

Abstract
The purpose of this work is to evaluate the energy impact on the distribution network at the point of connection of an electric plant of a railway car park where some charging points for electric vehicles have been installed. The first part presents a summary of the current state of development of electric mobility, describing the various types of electric vehicles, the charging infrastructure and the possible applications in Smart Grids. In the second part, instead, a possible load curve of the car park in question is simulated and, based on the principle of Vehicle-to-Grid technology, an appropriate algorithm has been developed. Such algorithm, exploiting the possibility of a two-way energy flow between the connected vehicles and the electricity grid, perform a Peak Shaving of the load curve of the plant under examination in order to avoid absorption peaks normally difficult to manage by the DSO. The work also presents the coupling with a photovoltaic system designed specifically for the car park.File | Dimensione | Formato | |
