In addition, he has conducted more than thirty research projects with Iranian power companies. Dr. Eidiani is an Associate Editor for the IET Journal of Engineering (JOE), and Journal of Electrical Engineering & Technology (JEET), and an Editorial Board for the International Journal of Applied Power Engineering (IJAPE), and 9 other journals. He has been a Board Member of Khorasan Electric Generation Company. Dr. Eidiani is the Editor-in-Chief of the International Journal of Energy Security and Sustainable Energy. He is the author of "Fundamentals of Power Systems Analysis I: Problems and Solutions" published by Taylor & Francis Group. Kumars Rouzbehi (Senior Member, IEEE) Received his Ph.D. degree in Electric Energy Systems from the Technical University of Catalonia (UPC), Barcelona, Spain, in 2016. Prior to this, he was an academic staff at the Islamic Azad University (IAU), Iran, from 2002 to 2011. In parallel with teaching and research at the IAU, he was the CEO of Khorasan Electric and Electronics Research Company, from 2004 to 2010. From 2017 to 2018, he was an Associate Professor at the Loyola Andalucía University, Seville, Spain. In 2019, he joined the Department of System Engineering and Automatic Control, University of Seville, Spain. He is the patent holder for AC grid synchronization of voltage source power converters and has contributed to over 100 technical publications, including books, book chapters, journal papers, and technical conference proceedings. Professor Rouzbehi has been a TPC Member of the International Conference on Electronics, Control, and Power Engineering (IEEE.ECCP), since 2014, a Scientific Board Member of the (IEA) International Conference on Engineering and Management, since 2015, and a TPC Member of COMPEL 2020. He is an Associate Editor of the IEEE Systems Journal, IET Generation, Transmission and Distribution, IET Renewable Power Generation, High Voltage (IET), and IET Systems Integration. He received the Second Best Paper Award 2015 from the IEEE Power Electronics Society, IEEE Journal of Emerging and Selected Topics in Power Electronics.
