Latest development and key technologies of offshore wind power for grid integration.

Aiming at development trend of wind power industry and research status of grid integration of offshore wind farms, a review was given on the key technologies of offshore wind power for grid integration and latest development. First of all, influences of offshore wind power injection to safe and stable operation of power grid was analyzed systematically. Firstly, grid dispatching, voltage control and frequency regulation will be influenced. Secondly, power flow distribution will be changed. Thirdly, power quality will be effected. In order to solve these problems, some key technologies for grid integration of offshore wind power were studied in recent years, such as low voltage ride through, ramp rate control, flexible direct current transmission based on voltage source converter, reactive power compensation, automatic output power adjustment and on-line monitoring and fault diagnosis. The results indicate that offshore wind power is the main development direction of the wind power industry in the future, and grid integration is a high effective way for its large-scale exploitation and utilization. Finally, some research focus and research directions about grid integration of offshore wind power have been put forward. [ABSTRACT FROM AUTHOR]
