The modular multilevel converter (MMC) is a promising option to integrate battery energy storage systems (BESSs) into the power system. Both half-bridge submodules (SMs) and full-bridge SMs can be used to implement an MMC. For MMC-based BESS, it is important to have sufficient battery fault toleranc...
