The use of diesel generators to supply electricity to small remote islands is both costly and environmentally troublesome. On the other hand, small island networks pose peculiar stability and reliability problems when renewable energy sources are added. This paper regards the installation of a hybrid power plant (photovoltaic, plus lithium battery and synchronous condenser) in Giglio island, to replace existing diesel units. This paper discusses the general overview of the project and presents steady-state and dynamic simulations of the proposed energy system.

Electricity in small remote islands is generally supplied by 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 Giglio (a small island in the Tyrrhenian Sea), with an hybrid power plant which includes a photovoltaic power plant and a lithium battery energy storage system.
