Research on MMC-HVDC multi-objective model predictive control strategy under asymmetric faults
Energy Reports, 2020 When an asymmetric fault occurs on the AC side of the MMC-HVDC system, a large number of non-characteristic harmonics will be generated on both sides of the system, which will affect the operation of the system.
