Integrating renewable energy sources in the Tuscan Archipelago

摘要

Electricity generation in small remote island is generally performed using diesel generators, leading to high energy cost and significant local pollution; the integration of renewable energy sources in such small networks is hindered by stability and reliability issues, as well as environmental constraints. The paper deals with the replacement of diesel generation in Giannutri and Giglio islands (two small islands in the Tyrrhenian Sea), with a hybrid power plant, including photovoltaic power plants and energy storage systems. Steady state and dynamic simulations have been carried out, in order to verify network reliability and stability; moreover, environmental impact assessment and authorization issues have been also considered. Environmental impact assessment and authorization issues are also considered, evidencing that the smart island project will introduce significant advantages both in pollution terms and of energy cost.
