Dr. Vasileios Kleftakis received his Diploma and Ph.D. in Electrical Engineering from the School of Electrical and Computer Engineering, National Technical University of Athens (NTUA). His Ph.D. research area was LVDC systems focusing on DC Microgrids and DC railway systems. His research interests also include: Real-Time simulation, Distributed Generation, Microgrids, management of regenerative energy (braking energy) and storage integration into DC railway systems. He was a member of CIGRE WG C6.30 “The Impact of Battery Energy Storage Systems on Distribution Networks”. Moreover, he was a member at IEC System evaluation Group committee (IEC-SEG4) with title ”Low Voltage Direct Current Applications, Distribution and Safety for use in Developed and Developing Economies”. He has participated in several European projects (e.g. Sustainable, DERri, NobelGrid) and national projects.
