In the evolving landscape of the Italian generation scenario, renewable generation is gradually supplanting traditional power plants, causing a reduction of electric system inertia and potential inertia shortages. This study compares two different methodologies for estimating the necessary inertia to be integrated into the Italian Transmission Network by the year 2030, aiming to constrain the derivative of frequency according to predefined thresholds. The analysis encompasses renewable and conventional sources for additional inertia provision. Furthermore, the described approaches offer optimal combinations of these technologies based on techno-economic considerations. The 2030 scenario is delineated utilizing data sourced from Terna S.p.A, the Italian transmission system operator.

Abstract
In the evolving landscape of the Italian generation scenario, renewable generation is gradually supplanting traditional power plants, causing a reduction of electric system inertia and potential inertia shortages. This study compares two different methodologies for estimating the necessary inertia to be integrated into the Italian Transmission Network by the year 2030, aiming to constrain the derivative of frequency according to predefined thresholds. The analysis encompasses renewable and conventional sources for additional inertia provision. Furthermore, the described approaches offer optimal combinations of these technologies based on techno-economic considerations. The 2030 scenario is delineated utilizing data sourced from Terna S.p.A, the Italian transmission system operator.
