Once modular multilevel converter (MMC) dc-side short-circuit fault occurs, the conventional fault ride-through (FRT) strategy indeed eliminates dc fault current quickly with the utilization of full-bridge submodules. Thereupon, ac-side active power declines sharply. However, instantaneous high power outage will cause ac-grid power and frequency …
