Transient Fluctuation Suppression Strategy for MMC Flexible DC Systems Based on Gain-Varying Extended Disturbance Observer

Transient Fluctuation Suppression Strategy for MMC Flexible DC Systems Based on Gain-Varying Extended Disturbance Observer

Modular Multilevel Converter Based High Voltage Direct Current (MMC-HVDC) system is an important technical means to realize grid connection and transmission of new energy. When the external disturbance occurs in the MMC-HVDC system, the submodule capacitance voltages suffer instant impact due to the...
