DC current oscillations reduction in MMC-HVDC system

Modular multilevel converter (MMC) is a type of voltage source converter (VSC) that offers several advantages, permitting it a suitable technology in high voltage direct current (HVDC) transmission systems. The conventional non-energy based control method; current does not manage capacitor energies inside MMC modules and produced DC current ...
