Phd Ahmed ZAMA “Modeling and Control of Modular Multilevel Converters (MMCs) for HVDC applications”
Common understanding today is that the challenges to develop the SuperGrid are huge at many levels (e.g.: political, societal, economical, financial, scientific, technical…). It is also commonly accepted that the SuperGrid will require novel technologies (breakers, cables, converters…) and operating principles (e.g.: transition from a more passive essentially AC-based power system to a more active AC/DC-based one). This thesis deals with the development of a key actor for SuperGrid technology, that is, AC/DC converters.
