Title: Introduction to power system stability issues – RTE’s perspective

Abstract: The presentation will be a short introduction to issues faced by Transmission System Operators (and in particular RTE) related to power system stability and their evolution due to the large integration of power electronics interfaced resources. A particular focus will be put on the slow interactions between converters that would be a concrete challenge in France in five to ten years, and to the related open questions.

Bio: Adrien Guironnet received the M.A.Sc. degree from the KTH Royal Institute of Technology, Stockholm and Ecole Supérieure d’Electricite, Paris, in 2012. Since then, he has been with Réseau de Transport d’Electricité (RTE), R&D department, holding different positions around power system simulation tools and stability issues. He is currently coordinating the research efforts around power system stability.

Title: High-fidelity modeling in modern power grids — analysis, stability, and control

Abstract: With the rapid incorporation of converter interfaced generation in the grid, the time scales over which power system dynamics take place get more convoluted. For example, the dynamics of inverter controls occur on time scales that overlap with those of transmission lines in ways that weren’t the case for synchronous machines. Therefore, at the time to perform a power system analysis, there are new questions arising regarding what degree of model fidelity is necessary for a given analysis. In this talk, Gabriel will present work on modeling for power systems stability analysis. In particular, we look at the effect of transmission line and load modeling. We use models for transmission lines that capture higher bandwidths and frequency dependence not captured by common models, and we use dynamic power electronic load models to represent the large amount of power electronic loads also on the grid. We pay close attention to how our choices of models affect the small signal and transient stability conclusions we arrive at, and what might be the most appropriate model for the different analyses.

Bio: Gabriel  Enrique Colon-Reyes is a PhD candidate in the Electrical Engineering and Computer Sciences Department at the University of California, Berkeley in the USA. He expects to graduate in May 2025. He obtained his Bachelor of Science in Electrical Engineering from University of Puerto Rico, Mayagüez in 2019 and received the Georg Simon Ohm award for best EE student. Gabriel’s research interests are in using mathematical analysis tools to solve modern power systems problems related to the growing amounts of converter interfaced generation (CIG) in power grids. More specifically, Gabriel has worked on i.) hybrid control strategies for modeling and controlling grid-forming inverters, ii.) transmission line modeling and their effect on stability analysis of power systems, and is currently working on iii.) load modeling and their effect on stability analysis of power systems iv.) system grid strength and load models and their effect on power system stability. Lastly, Gabriel has won several awards during his student career, most recently the 2024 Evergreen and 2024 Demetri Angelakos awards from the UC Berkeley EECS department for mentorship, and community building.
