Resumo: The inertia of a power system provided by synchronous generators is considered a key aspect for stability. Since the beginning of the century, the decommissioning of synchronous generators has been going on at a steady pace, thus threatening stability. The importance of estimating the available inertia in a power network by synchronous generators and mainly the “black-one” by virtual synchronous generators emulation by inverter interfaces renewable sources has thus steadily increased. This is reflected in the large amount of research on this topic that one can
find in the scientific literature. Limited to the “Scopus” abstract and peer-reviewed article citation database, those including the “inertia” and “power system” keywords in their abstract have increased from just 30 in 2000 to 1200 in 2022. Even if the literature regarding this topic is vast and rapidly growing, the problem is still open despite the tireless work of numerous research groups.

Over the last three years, together with, but not only, the researchers of the group I belong to at the Polytechnic of Milan, I have addressed this challenging problem from different perspectives. We proposed several solutions by fully exploiting concepts deriving from circuit theory and simulation, analysis of non-linear dynamical systems, deep learning, and optimization. We had the opportunity to be partially supported by the Italian MUR through a PRIN 2022 project and by Terna S.p.A., the Italian transmission system operator. In this presentation, I would like to briefly share the results of our research.

Short Bio: Federico Bizzarri (Senior Member, IEEE) was born in Genoa, Italy, in 1974. He received the Laurea (M.Sc.) five-year degree (summa cum laude) in electronic engineering and the Ph.D. degree in electrical engineering from the University of Genoa, Genoa, Italy, in 1998 and 2001, respectively. Since October 2018 he has been an associate professor at the Electronic and Information Department of the Politecnico di Milano, Milan, Italy, where he had been a research assistant since June 2010. In 2000 he was a visitor to EPFL, Lausanne, Switzerland. From 2002
to 2008 he was a post-doctoral research assistant in the Biophysical and Electronic Engineering Department of the University of Genova, Italy. In 2009 he was a post-doctoral research assistant in Advanced Research Center on Electronic Systems for Information and Communication Technologies “E. De Castro” (ARCES) at the University of Bologna, Italy. His main research interests are in the area of computational electrical engineering. It translates into the study, modeling, and computational analysis of complex electrical and electronic systems. He is a research fellow of
the Advanced Research Center on Electronic Systems for Information and Communication Technologies “E. De Castro” (ARCES) at the University of Bologna, Italy. He served as an Associate Editor of the IEEE Transactions on Circuits and Systems I and he received the 2012-2013 Best Associate Editor Award of that journal. He is currently serving as an Associate Editor for the IEEE Open Journal of Circuits and Systems and he received the 2023 Best Associate Editor Award of that journal. He is currently the Chair of the IEEE Nonlinear Circuits and System Society
Technical Committee.
