Power Control of Offshore Wind Power System through Modular Multilevel Converter

This paper presents an Adaptive Fuzzy Sliding Mode (AFSM) Current Control of Modular Multilevel Converter (MMC) for integration offshore wind power system to on-grid network. In order to design adaptive robust control strategy,mathematical dynamic model of MMC using rotating d-q theory based upon positive and negative symmetrical components has been developed. Time-domain simulation studies are carried outin the Matlab/Simulink environment to verify the performance of the overall proposed control system. The simulation results show that the proposed controller provides the load with a set of sinusoidal, three-phase balanced voltages despite sever unbalanced voltage conditions.
