Analysis of the Integration of an Electric Bus and an Electric Vehicle with Grid-Connected PV Systems and a Storage System

This paper aims to analyze the electricity consumption of an electric bus (eBus) and a passenger electrical vehicle (EV) in order to investigate the viability of powering such vehicles with grid-connected solar photovoltaic (PV) systems. The integration of a battery to the system is also explored, with the analysis of two different energy management strategies. The analysis is based on energy production data of building-integrated PV systems in the Fotovoltaica/UF SC laboratory (www.fotovoltaica.ufsc.br), and consumption measurements of the laboratory's eBus, which makes 5-daily-round trips of 52 km each, and a Renault Twizy electric vehicle. The results showed that the PV systems can play an important role in reducing the high-load demand generated by electromobility. However, the addition of a battery for storing the surplus of PV energy would be advantageous to decrease the grid consumption and reduce the dependence of the public grid, demonstrating both technical and economic benefits.
