Research on MMC-HVDC system control strategy for large-scale wind farms
摘要
Abstract
Flexible HVDC (high-voltage direct current)is the key issues of large-scale wind farms,with the modular multilevel converter (MMC)being the development trend of flexible HVDC technology.In this paper,the mathematical model of MMC is set up and a novel MMC-HVDC system control strategy is proposed for large-scale wind farms.With hierarchical control, based on the novel strategy,the whole MMC-HVDC system control strategy is divided into sys-tem level control,inverter control and valve control module voltage control.Moreover,feedback linearization controller is introduced into the inner current ring of system side MMC control in or-der to enhance the dynamic performance of control strategy.The MMC converter controller structures at the system side and the wind field side are provided for the realization of the reliable access to the power grid of the large-scale wind power.Simulation results based on actual system are to verify the correctness and effectiveness of the proposed method.关键词
