Cover Story: This paper provides an assessment of the technical and economic impacts of a microgrid at the building level, considering photovoltaic generation, battery storage and the use of electric vehicles in a vehicle-to-building system. Several tests were conducted using real on-site data to calculate the overall efficiencies of the different assets during their operation. An economic assessment was carried out to evaluate the potential benefits of coordinating battery storage with a vehicle-to-building system regarding the flexibility and cost-efficient operation of the microgrid. The results show that these two systems effectively increase the levels of self-consumption and available flexibility. Furthermore, economic benefits are highly dependent on the variability of tariffs and the costs of energy storage systems, as well as the efficiency of the equipment used in the conversion chain.
