Modular Multilevel Converters (MMCs) are a type of power electronic converter used for medium- and high- voltage direct current convertion, consisting of a multitude (up to several hundreds) of series-connected sub-modules of relatively low voltage rating.
The three MMC legs on the right side of the model are operating as inverters and are connected to the three phases of the Constant impedance load . The rated voltage of the load is 230kV, its frequency is 60 Hz, and its rated power is 1000 MVA. This side of the model is referred to as the Inverter side.
The MMC is an emerging topology for high-power and high-voltage VSC application ; it is suitable for either HVDC transmission or FACTS applications [24, 25]. For very high-power applications, an MMC is also an alternative, and potentially preferable, to a multilevel converter .
