Dynamic Thermal Rating and development of Renewable Energy Zones in Siciliy

Sicily, an Italian region in the south of Italy, is candidate to become an energy "hub" in the Mediterranean in the coming years. Its geographical location, between the African continent and Europe, makes it a crucial hub for the distribution of electricity flows. The region has a high potential for exploiting renewable energy sources. Inspired by the Australian “Renewable Energy Zones” model, identifying existing Renewable Energy Zones (REZs) and properly designing future REZs on the territory will simplify and enhance the operation of the grid.A very effective tool in managing REZs is Dynamic Thermal Rating (DTR) technology. This technology allows dynamic rating on the high voltage transmission system, ensuring the maximum allowable current is transported while preventing the annealing of the electrical conductor and adhering to all necessary safety parameters.In the work carried out in collaboration with Terna S.p.A (Italian Transmission System Operator), the goal was to assess the application of this technology on the Sicilian electricity grid, to reduce potential network congestion and system inefficiencies.The results obtained demonstrate the significant potential of Dynamic Thermal Rating in Sicily. These devices would allow a substantial increase in the current flow on electrical lines without violating safety limits.
