Use Case description
The pilot project proposed is related to the distribution grid of San Severino Marche, a town of about 13,000 inhabitants in the Macerata province. In the past, the area reported a hydro resources exploitation while, recently, photovoltaic generation penetration rises year after year. Moreover, due to the agricultural activities, good opportunities are also related to biomasses. Vice-versa, the energy needs of the loads are quite limited, consequently a reverse power flow regularly occurs. In such a scenario, the main goal of the Distribution system operator (DSO) is the effective management of the Distribution Grid and the maximization of the hosting capacity. Actually, distribution networks are built as radial systems, but with the possibility of back-feeding during contingencies. They have some advantages over meshed networks, such as lower short-circuit currents and simpler switching and protecting equipment. On the other hand, the radial structure provides less overall reliability. Nowadays, DSOs have the opportunity to change the topology of their grids in order to obtain an optimal configuration, in terms of losses or other operational indicators (Quality of Service, Hosting Capacity, etc.). To this purpose, it is pivotal to perform an accurate estimation of the state of network, in real time, but also on a predictive base.
ASSEM SPA will cooperate with POLIMI, UNE and Energy@work in order to activate a Pilot Use Case on the distribution grid of S. Severino Marche. The goals will be related to the advanced monitoring of the grid, to the forecast of the power flows and, consequently, to the day ahead topology optimization of the grid. Generators will be consequently managed by the electric protection and remote control system of the DSO and exploited in order to optimize the grid reliability and efficiency. Moreover, an innovative platform will be activated to evaluate the effectiveness of a coordinated control of Medium Voltage generators performed by the DSO in order to provide ancillary services to the main grid. Eventually, storage mobile apparatuses will be tested both in the DSO perspective and in the final user one.
