Spatial repetitive controller for improved steady state performance of droop regulated modular multilevel converter in wind farm application

Abstract

Modular Multilevel Converters (MMC) are emerging as a promising technology for high power conversion at high voltage levels. When frequency droop regulated MMC is used as a front-end converter to integrate wind farm into HVDC grid, variation in the fundamental operating frequency results in the change of circulating current harmonic frequencies. Due to this… (More)
