5 ENERGIA 2020 Project - University of Genoa ( ) The project "Energy 2020 of the University of Genoa is an important R&DD project related to the concept of Sustainable Energy (renewable energy, energy saving and reduction of CO 2 emissions) and Smart City. The project, which has been developed thanks to a full public financing, is designed to implement within the University Campus of innovative energy systems aimed at reducing operating costs, CO 2 emissions and, at the same time, at creating a comfort working environment for Campus users.

6 The Smart Polygeneration Microgrid (SPM) Project Special project in the energy sector funded by the Italian Ministry of University and Research SPM is a 3-phase low voltage (400 V line-to-line) intelligent distribution system running inside the Campus and connecting: 3 mchp Gas Turbine (160 kwe, 284 kwth) fed by natural gas; 1 PV field (100 kwp); 3 CSP equipped with Stirling engines (3 kwe; 9 kwth); 1 absorption chiller (H 2 O/LiBr) with a storage tank; 2 electrical storages: NaNiCl 2 batteries (100 kwh) Lithium-ion Battery (25kWh) 2 PEV charging stations.

10 SPM OPTIMAL SCHEDULING / DAY-AHEAD OPERATIONAL PLANNING Our Energy Management System uses o costs and revenues functions; o forecast of electric and thermal energy demands; o operative constraints (equipment ratings, maximum power ramp, etc.); o forecast of the renewable units production by resorting to weather services and historical records to compute a scheduling for dispatchable sources including storage, which minimizes the daily energy costs. The optimization process has a time-horizon of 1 day (typically: the one of a day-ahead energy market session; max. time horizon is one week), subdivided in 15 (or 30 or 60) minutes time-intervals. The optimization method is based on linear programming.

11 SPM OPTIMAL SCHEDULING / REAL-TIME MANAGEMENT Based on the dispatch plan, any deviation that occurs during operation concerning with the energy exchange with the external network is shared at minimum cost among generators, storage systems, and loads, which can be controlled, so that the planned value can be met. For instance, if PV energy is less than the expected one, the lack of energy is compensated by increasing the power delivered by the energy storage system
