E-Mobility Microgrid Laboratory at the Savona Campus of Genova University

摘要

The goal of the present paper is that of presenting the main research activities carried out at the Savona Campus of Genova University in the electric mobility and microgrid sector, with a particular focus on vehicle-to-grid (V2G) and vehicle-to-building (V2B) projects. The infrastructures of the E-Mobility & Microgrid Laboratory are described highlighting the peculiarity of having a polygeneration LV microgrid with renewable power plants, storage systems, electric and thermal loads represented by the buildings among which one acts as a prosumer, and charging points for electric vehicles (EV) with the possibility of exploiting V2G and V2B technologies. Moreover, the paper reports the Energy Management System (EMS) developed to optimally operate a portion of the aforesaid facility consisting in the prosumer building, equipped with a PV plant and a bidirectional EV charger, and connected to the microgrid. As highlighted in the result section, the attention is pointed on two different approaches used to model EV charging and discharging.
