The Modular Multilevel Converter (MMC) system has many advantages over conventional voltage source converters and therefore can be used in dc power transmission, micro grid, or renewable energy applications. While MMC’s distinctive topology offers many new features, it also necessitates a sophisticated controller to deal with extra control requirements. This paper presents a control scheme with...
