Electric vehicle use in public fleets: The case of the Genoa University

Abstract

Abstract-Electric mobility is assuming a central role in the new world energy scenario where Renewable Energy Sources (RES) have increased their contribution to the electricity production, mainly due to the fact they are characterized by a reduced environmental impact; in the aforesaid context, Electric Vehicles (EVs) can play a significant role to facilitate the integration of RES into the power grid, also within smart grid infrastructures. Public administration represents one of the sectors that can mostly benefit from the use of the EV technology in its fleets; in many countries governments have introduced incentive policies to support the spread of the electric mobility and car manufacturers are developing EVs for urban transportation users. In this paper, the attention is focused on a smart microgrid project developed at the University of Genoa and based on the integration of RES, EVs and storage systems. In particular, the attention is here pointed on the use of the EVs to highlight the different habits of recharge adopted at the Genoa University. The paper describes the smart microgrid test-bed facility at the Savona Campus and reports the most significant results relative to an experimental campaign conducted on EVs.

Electric Vehicles Charging Optimization to Improve the Insertion Considering the Brazilian Regulatory Framework

“…The project counts with two charging stations on the Savona campus, which allows collection of data to be used in studies about the impacts of EVs on the electricity grid. 50 Therefore, as shown by the result of this current study in Brazil, it should be possible to use the region's low charging characteristics to encourage the sale of EV based on specific public policies. Moreover, it would be possible to stimulate EV market growth in the country without a significant impact on the electricity grid.…”

“…One example is the project “Energia 2020” developed by a public partnership between the Government of Italy and the University of Genoa. The project counts with two charging stations on the Savona campus, which allows collection of data to be used in studies about the impacts of EVs on the electricity grid …”

Efficient Automation of an HEV Heterogeneous Fleet Using a Two-Stage Methodology

“…Constraint (13) stands for the non-negativity condition of , , . To avoid charging at the starting intersection i ( , = -1), during the first delivery, and for the subsequent deliveries with intersection i ( , ≥ 0) in which there is no charging station ( = 0), (14) is used. The recharge energy, , , , is calculated in (15) which depends on the variables , , and , , at intersection i which is equipped with charging station, = 1.…”

“…In [13], a sensitivity analysis has been done to find the optimal charging process of the EV fleet and the flow exchange between the power grid and EVs. In [14], optimal recharging of EVs considering the different habits of owners was a part of a smart microgrid project in order to manage energy usage, fuel costs, and carbon dioxide emissions, while, as a storage device, addressing the fluctuations of renewable energy output. In [15], a predictive management system was proposed for optimal charging of the HEVs fleets while the charging station was equipped with PVs taken into account the distribution network restrictions.…”

Feasibility analysis of a solar‐assisted electric vehicle charging station model considering differential pricing

“…4 They can be an excellent alternative for fleets used in tertiary sector and by public administrations, with the purpose to reduce fuel costs, primary energy consumption, and carbon dioxide emissions. 5,6 Some common concerns for the same have surfaced such as long charging time and limited battery capacity. 7 As a result, convenient charging has become a high priority to ensure a quick and smooth transition.…”
