He is an emeritus professor of the Department of Electrical and Computer Engineering of the Aristotle University of Thessaloniki (AUTH), where he served from 1985 to 2023 consecutively at all faculty levels, and from 2002 at the rank of professor with the subject "Design and Operation of Electrical Systems Energy". He holds a degree in Mechanical - Electrical Engineering from the National Technical University of Athens (1979) and a PhD in Electrical Engineering from the Georgia Institute of Technology, USA. (1984). He was the president of the Department of Electrical and Computer Engineering of the AUTH (2020-2022), the Deputy Chairman of the Energy Resources Management Engineering Department of the AUTH based in Kozani (1999-2004), the Director of the Electricity Sector of the AUTH EECE Department ( 1997-1999 & 2008-2010) and director of the Electrical Energy Systems Laboratory of the DEECE of the AUTH (2006-2010 & 2016-2019). He was the scientific manager of 35 research projects funded by various bodies (European Commission, GGET, NSRF, Greek energy industry). He has written a scientific book and more than 200 scientific articles in international journals and conferences. He was a member of the editorial board of scientific journals (IEEE Transactions on Power Systems, IEEE Transactions on Smart Grid, IEEE Transactions on Sustainable Energy, IET Renewable Power Generation and Journal of Modern Power Systems and Clean Energy), member of scientific committees of international conferences (IREP, PSCC , ISGT, ISAP, etc.) and invited speaker at many scientific conferences. He is a Life Fellow of the IEEE and an honorary member of the T.E.E.
Electricity Markets
Socioeconomic forces and technological developments have led to the restructuring of electricity systems in many regions of the world, transforming them from vertically integrated regulated monopolies to competitive systems based on the free market. Competitive electricity markets represent perhaps the most demanding supply chain. Electricity presents important peculiarities as a tradable product: it requires immediate delivery, its transportation is problematic, its price shows large fluctuations even within the same day, which are not visible to a large part of the demand, which remains apathetic to price fluctuations. Despite these obstacles, the past twenty-five years have seen exciting developments in the design and operation of competitive electricity markets. In my talk, after a brief review of the history of electricity system restructuring, I will outline the key challenges in designing and operating competitive electricity markets. I will review the key elements and alternative approaches adopted in different systems and discuss what we have learned so far in this area. I will also discuss the new challenges due to the mass integration of renewable energy sources.
