The renewable energy source (RES) penetration in end use must be strengthened to reach the prefixed decar-bonization targets. A penetration obstacle is represented by the Power Grid

designed with an architecture disinclined to RES unpredictability. Nowadays

different solutions are available to integrate these latter issues without affecting the Grid

among these

the reversible Solid Oxide Cell (rSOC) promises high efficiencies and the possibility to control energy fluxes in both production and storage. In this study

a series of hourly simulations based on real data were designed to evaluate the rSOC capacity to integrate a large number of RESs in the end use of three different buildings

through analyzing the possible congestion on the Power Grid. As a rSOC model we chose the Smart Energy Hub proposed by Sylfen while for the buildings we selected a school

a hotel

and an office located in Procida

Italy. The results show the rSOC capacity to integrate RES increased from 40% to 62% according to the storage capacity and the building's hourly load curve and seasonal consumptions.
