Abstract: Aiming at using offshore renewable energy effectively, hybrid offshore wind and tidal current power generation system was researched. Complementarity of offshore wind and tidal current power was analyzed from the perspective of time and space qualitatively, and advantages of the pile platform common used by the two generation systems were explained briefly. Topology of hybrid offshore wind and tidal current power generation system was analyzed, simulation model of the system was build, and main evaluation indexes were introduced. Capacity allocation optimization of hybrid offshore wind and tidal current power generation system in Guishan waterway of Zhoushan was accomplished by HOMER. Sensitivity analysis of wind and tidal current speed was conducted. The optimization results indicate that hybrid offshore wind and tidal current power generation system is more costeffective when the system satisfies the set constraint condition. The results illustrate the applicability of offshore wind power generation system, tidal current power generation system and hybrid offshore wind and tidal current power generation system.

Key words: hybrid offshore wind and tidal current power generation system; capacity allocation；HOMER; sensitivity analysis
