Real-Time Simulation in Modern Power Systems: Conceptual Foundations, Industrial Implementation and Strategic Impact
The lecture will address real-time simulation not merely as a technological tool, but as a paradigm shift in the way modern power systems are researched, designed, and validated. From a conceptual and strategic perspective, it will discuss what real-time simulation truly is—and what it is not; its role as a bridge between mathematical modeling and industrial hardware; the difference between offline simulation and HIL/PHIL validation; its advantages in the development of protection, converters, and systems dominated by power electronics; as well as its current limitations and areas of opportunity.
I believe this perspective—integrating theoretical foundations, practical implementation with industrial equipment, and experience in advanced experimental validation—can offer a high-level technical and strategic vision aligned with the current challenges in power, electronics, and computing.
About Dr. Segundo-Ramírez
Dr. Segundo research focuses on the advanced modeling, stability analysis, control, and protection of converter-dominated power systems, addressing phenomena such as harmonic and electromagnetic stability, resonances, grid–converter interaction, small-signal analysis, bifurcations, and electromagnetic transient studies, with particular emphasis on transmission lines. His recent work centers on adaptive remedial action schemes, stability-boundary analysis in systems with high renewable penetration, grid-forming/grid-following converter integration, and digital twins for wide-area stability, protection, and control—developments validated experimentally under conditions representative of real operation. He has published more than 50 articles in prestigious international indexed journals and has led applied research projects funded by SECIHTI, in partnership with the mining industry, Schweitzer Engineering Laboratories, and national and international universities.
He is co-founder and Research Director of AZTEKNIA, and since 2011 has directed the Power Systems Laboratory, equipped with real-time digital simulation platforms (RTDS and OPAL-RT), reconfigurable power electronics, industrial digital relays, and HIL, CHIL, and PHIL capabilities. A member of Mexico’s National System of Researchers (SNII, Level I) since 2011 with a PRODEP profile, he has directed 8 doctoral, 20 master’s, and 4 undergraduate theses. He was also co-responsible for creating the Master’s in Power Systems in collaboration with Schweitzer Engineering Laboratories (SEL de México)—the first graduate program in Mexico structured in direct partnership with the power industry, and later the first offered online in this specialty—and has served as its academic coordinator, as well as coordinator of the graduate program in electrical engineering.
