Renewable Energy Penetration Strengthened Using a Reversible Solid Oxide Cell Installed in a Building

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.
