An adequate level of power system inertia and load damping is essential to ensure frequency stability following power imbalances. Prior to that, however, it is first necessary to be capable of estimating these parameters. In this paper, we propose an original method to estimate the global inertia and damping of a power system comprising conventional synchronous generators, as well as modern generation units based on grid forming and following converters, which can provide virtual inertia and load damping. The effectiveness of our approach is tested on a modified version of the IEEE39 power system with ambient noise.

Abstract
An adequate level of power system inertia and load damping is essential to ensure frequency stability following power imbalances. Prior to that, however, it is first necessary to be capable of estimating these parameters. In this paper, we propose an original method to estimate the global inertia and damping of a power system comprising conventional synchronous generators, as well as modern generation units based on grid forming and following converters, which can provide virtual inertia and load damping. The effectiveness of our approach is tested on a modified version of the IEEE39 power system with ambient noise.File in questo prodotto:
