Abstract:

Compared with that of the existing offshore wind farms, the impact of deep-sea offshore wind farms on the operation reliability of power systems is more complex due to varied oceanic and climatic conditions. In order to analyze the operation reliability of large-scale deep-sea offshore wind power integration, a reliability assessment model considering the effects of mesoscale eddies and tropical cyclones is proposed, which is used to evaluate the internal mechanism between critical marine factors and system reliability. The effects of mesoscale eddies, tropical cyclones, and corresponding air-sea interactions in the East China Sea on system reliability are analyzed by using the modified Roy Billinton test system (RBTS). The simulation results show that the mesoscale eddies and tropical cyclones have a significant influence on the reliability of the wind power integration system, and the influence shows a seasonal trend. Furthermore, an energy storage system is applied to the simulation case to improve the reliability level and reduce the negative impacts.

Key words:offshore wind power; power system; mesoscale eddy; tropical cyclone; air-sea interaction; reliability assessment
