Semi‐hot redundant control method for modular multilevel converter‐based high‐voltage direct current systems under submodules fault

Abstract A modular multilevel converter‐based high voltage direct current (MMC‐HVDC) system involves a large number of cascading submodules (SMs). The failure of SMs may critically degrade the system performance. Therefore, several redundant SMs can be incorporated and reasonably controlled to ensur...
