Economic impact of investments in weather forecasts for distribution system operators: the Italian case
A larger integration worldwide of Renewable Energy Sources (RES) in the electricity distribution system is certainly desirable, to reduce CO2 emissions and to contribute to a sustainable development. However, the increasing penetration of renewable energy is a challenge for the system performance, because it affects the Power Quality (PQ) and the load management, forecasting and scheduling. To reduce the impact of intermittent energy sources on network security, it is mandatory to predict with reasonable accuracy the renewable energy variations.
