Dr Mostefa Kermadi

Mostefa Kermadi received an Engineering degree (Dipl. Ing.), M.Sc., and Ph.D. in Automatic Control from the National Polytechnic School (École Nationale Polytechnique). During his Ph.D. work, he was a Visiting Researcher at the Centre of Electrical Energy Systems, Universiti Teknologi Malaysia. After Ph.D., he joined the University of Malaya as a Post-doctoral Research Fellow at the Power Electronics and Renewable Energy Research Laboratory. Later, he became a Lecturer in the Department of Electrical Engineering at the same university. Currently, he is a Lecturer (Assistant Professor) at the School of Engineering, University of Leicester. He has been listed by Stanford University among the top 2% scientists in the world in their respective field in the year 2023. His research interests include the control of power converters, the application of artificial intelligence for power conversion and management in renewable energy systems, and the grid integration of renewable energy systems.

Dr. Mostefa Kermadi is an energetic early career researcher who has made several contributions to the field of controlling energy conversion systems using power electronics. He has authored and co-authored 30 publications in refereed international journals and more than 20 conference proceedings. His work involves pioneering research in maximum power point tracking (MPPT) for photovoltaic systems by applying artificial intelligence techniques. He holds a patent for developing an analytical modeling approach for photovoltaic arrays under partial shading conditions, which is covered by PV Magazine.

Dr. Mostefa has also worked on the robust integration of distributed photovoltaic power generators into the utility grid. He designed a half-bridge evaluation board for power converters which is currently used by many post-graduate students in their experimental test benches and enabled them getting their experimental results and publishing their works in reputable journals. As part of a consultancy project in Malaysia, the half-bridge prototype has been successfully adopted in a wireless power transfer battery charger for last-mile delivery robots developed by a Malaysian start-up company named Hello World Robotics.

His current research focus is on addressing challenges posed by the high integration of renewable energy sources and the high penetration of electric vehicles into modern power electronics-dominated grids. He is working on the development of optimal power processing techniques for grid-connected and vehicle-to-grid inverters, enhancing controller performance for both grid-forming and grid-feeding operation modes with the objective of ensuring reliable and optimal performance in both grid-connected and islanded modes.
