With the fast development of offshore wind farm, the costeffective collection and transmission of large-scale offshore wind power has been an increasing concern. To better integrate the HVDC technology to the future offshore wind farms, advanced concepts of DC-DC power conversion and DC wind turbines can be extended to all-DC wind farm design. The state-of-art of three key technologies of the offshore all-DC wind farm with parallel connection are studied, including AC-DC power conversion of DC wind turbine, DC-DC power conversion of offshore step-up substation, and operation and control of offshore DC wind farm. A recommended configuration of offshore all-DC wind farm is proposed based on the modular multilevel converter. Suggested future work is also given based on the development trends of these key technologies.
