Costas Vournas
Constantine (Costas) Vournas is Professor Emeritus in the School of Electrical and Computer Engineering of National Technical University of Athens, Greece. He has published close to 200 papers in International Journals and Conferences and has co-authored the book “Voltage Stability of Electric Power Systems”. His research interests are in the area of power system dynamics, stability and control and include voltage stability monitoring and security analysis, renewable generation integration in power systems, and novel control applications for distribution and transmission systems. Fellow of IEEE (2005) and member of CIGRE. He received the IEEE/PES Prabha Kundur Award in 2019. He served as Region 8 Representative on the IEEE Power and Energy Society (PES) Governing Board (2011-2014). He is currently Chair of PES Greece Chapter, Past Chair of IEEE/PES Power Tech Steering Committee (2007-2019), and Chair of the IEEE/PES Power Systems Dynamic Performance Committee. Since 2021 he is Chairing the Energy WG of the IEEE European Public Policy Committee (EPPC) and is member of EPPC. From 2024 he serves as the Secretary of the Technical Council of IEEE PES
Challenges for Electrical Systems during the Energy Green Transition
The Green Energy Transition, i.e. the transition from the era of fossil fuels to the era of renewable energy sources is imposed by the necessity of maintaining the climate and human life on the planet at acceptable levels. The progress that has already been made is enormous and many times the expectations of a few decades ago. However, the change in electrical systems is only just beginning to take place: it is a transition from systems based on large power plants far from urban centers with large modern generators to distributed, dispersed systems of power generators connected via power electronic converters at all voltage levels ( high, medium, low) in distribution and transmission networks. The presentation will focus on the challenges this transition faces as well as open issues on power system control and security, computing and telecommunication tool needs, the changing consumer-producer role, and the implications for science. and the role of Electrical and Computer Engineering in the coming critical decades.
