Integrated operation control technology of MMC high and low voltage ride-through under weak grid

Integrated operation control technology of MMC high and low voltage ride-through under weak grid

In order to solve the problem of high and low voltage fault ride-through of modular multilevel converter （MMC） under weak grid，a multi-link control strategy including capacitance voltage balancing control of integral，phase-to-phase and upper and lower bridge arm，improved phase-locked loop （PLL） and...
