Sommario
Modern power systems with high penetration of renewable energy sources are increasingly exposed to significant levels of uncertainty, driven by the inherent variability and limited controllability of renewable generation. This evolving operating environment calls for advanced stability assessment and monitoring tools capable of supporting system operators in real time.In this talk, Prof. Luis F. C. Alberto will present two recent contributions from his research group addressing real-time voltage stability assessment in modern power systems.
The first contribution introduces a smooth formulation of the power-flow equations, designed to facilitate the treatment of limit-induced bifurcations and to enable the computation of robust stability margins under uncertainty.
The second contribution establishes theoretical foundations linking branch power flows to the maximum loading point of a power grid, with the ultimate goal of developing measurement-based tools for online voltage stability margin monitoring.
Biografia
Luis F. C. Alberto received his M.Sc. and Ph.D. degrees in Electrical Engineering from the University of São Paulo (USP), Brazil, in 1997 and 2000, respectively. He joined USP as a faculty member in 2002 and is currently a Full Professor in the Department of Electrical Engineering at the São Carlos School of Engineering, University of São Paulo. He was a postdoctoral visitor at Cornell University from 2004 to 2005 and later returned to Cornell as a visiting professor from 2011 to 2012. An active IEEE member since 1994 and an IEEE Senior Member since 2012, he received the Instituto de Engenharia Award in 1995 as the top student of the Engineering School at USP.His current research interests include modeling, monitoring, and stability assessment of modern power systems with high penetration of renewable generation. His contributions to power systems encompass methods for stability analysis, nonlinear control design, and observability analysis in state estimation. Professor Alberto is the co-author of Stability Regions of Nonlinear Dynamical Systems: Theory, Estimation, and Applications, published by Cambridge University Press, the author of a book on Stability Analysis of Power Systems in Portuguese, and of a book chapter on Stability and Equilibrium published in the SBA Encyclopedia of Automation and Control.
He has published more than 270 papers in journals and conference proceedings. He has also held leadership positions in scientific and professional societies, including Secretary Chair of the Brazilian Society of Automatica (SBA) from 2013 to 2014 and Treasury Director from 2019 to 2020. Within the IEEE Circuits and Systems Society, he chaired the Technical Committee on Power and Energy Circuits and Systems from 2013 to 2014 and served as Associate Editor of IEEE Transactions on Circuits and Systems II: Express Briefs from 2019 to 2023.
