Alberto started his professional career in 1989 with London Economics, an international economic consultancy, where he was eventually in charge of the industrial economic advisory practice.
Between 2003 and 2005 Alberto acted as an adviser to the Italian Government on environmental policy issues. Since 2004, he is an adviser at the Florence School of Regulation, where he regularly teaches on energy regulation and market design.
Alberto holds a Degree in Economics from Bocconi University in Milan and an MSc in Econometrics and Mathematical Economics from the London School of Economics, University of London.

Dr. S. Mark Halpin

Mark Halpin

Dr. S. Mark Halpin has been a driving force in the development of uniform power systems and power quality standards that promote worldwide reliability and safety.

He has worked tirelessly to create international standards that advance the state of the art of power systems engineering. His work in both the IEEE Power Engineering and IEEE Industry Applications Societies resulted in the creation of nearly 40 IEEE power standards.  Besides authoring or contributing to the IEEE Color Book series of power standard, he also initiated a major reorganization of the series, thus enhancing its usefulness to practicing engineers and engineering students.  He is also involved in Cigre and IEC activities where he has served as convener of numerous Working Groups dedicated to power quality concerns.  He is presently the Convener of IEC TC77/SC77A/WG2 dealing with voltage fluctuations and flicker.

Dr. Halpin, who is the Alabama Power Company Distinguished Professor of Electrical and Computer Engineering at Auburn University in Auburn, Alabama, has made many other related contributions. These include pioneering methods for both power quality measurement and techniques to identify areas of bulk power transmission systems subject to voltage and angular stability problems.

An IEEE Fellow in 2005 “For contributions to remote power quality measurements and standards,” Dr. Halpin received the 1998 IEEE IAS Outstanding Young Member Award and an IEEE Third Millennium Medal.  In 2006, he received the IEEE Charles Proteus Steinmetz Award “For leadership in the development and revision of power systems and power quality standards”  and he received the IEC 1906 Award in 2017 “For his dedication and his outstanding contribution to EMC standardization in the field of low-frequency conducted disturbances, in particular concerning voltage fluctuations and flicker.

Dr. Leszek S. Czarnecki


Leszek S. Czarnecki, IEEE Life Fellow, Alfredo M. Lopez Distinguished Professor at Louisiana State University, Titled Professor of Technological Sciences of Poland, granted by the President of Poland. He received the M.Sc., Ph.D. and Habilitation Ph.D. degrees in electrical engineering from the Silesian University of Technology, Poland. For two years he was with the Power Engineering Section, Division of Electrical Engineering, National Research Council (NRC) of Canada as a Research Officer, and for two years with the Electrical Engineering Dept. at Zielona Gora University of Technology, Poland. In 1989 Dr. Czarnecki joined the Electrical and Computer Engineering Department of Louisiana State University, Baton Rouge. For developing a power theory of three-phase systems with nonsinusoidal and unbalanced voltages and currents and for methods of compensation of such systems he was elected to the grade of Fellow IEEE in 1996. Development of the Currents’ Physical Components (CPC) – based power theory which explains all physical phenomena that specify power properties of electrical systems and creates fundamental for compensation systems of any complexity, was the major professional Dr. Czarnecki’s contribution to electrical engineering, for which he was nominated to the IEEE Proteus Charles Steinmetz Award. Dr. Czarnecki was decorated by the President of Poland, for his public activity in the United States, aimed at the acceptance of Poland in NATO, with the Knight Cross of the Medal of Merit of the Republic of Poland. Involved in mountaineering and underwater photography. He claimed, without oxygen support, Lhotse (No. 4 of the World) in the Himalayas (8350m); the main ridge of the Ruwenzori in East Africa (19 summits of average high of 5000m), Kilimanjaro and Mt. Kenya; traversed on ski (500km) Spitsbergen in the deep Arctic; claimed in Alps and in Andes; claimed solo McKinley, the highest mountain in North America. (,

Dr. Wilsun Xu


Dr. Wilsun Xu is currently a chair professor in the University of Alberta, Canada. He obtained B.Eng. from China in 1982, M.Sc. and Ph.D. from Canada in 1985 and 1989 respectively.  Dr. Xu worked as an electrical engineer in Canadian power industry for 7 years before joined the University of Alberta as a faculty member in 1996.  Dr. Xu is an expert in power quality. He was elected to IEEE Fellow in 2005 and a Fellow of Engineering Institute of Canada in 2006 for outstanding contributions to power quality research. Since 2008, he has been holding the position of Senior Industrial Research Chair in Power Quality awarded by the Natural Sciences and Engineering Research Council of Canada. Dr. Xu serves frequently as a panelist, seminar speaker in IEEE and other conferences, and as a consultant for industry. He is currently the Editor-in-Chief of the IEEE Transactions on Power Delivery and a board member of the Alberta Power Industry Consortium, Alberta, Canada.

Dr. Alfredo Testa
