WindWEC: Combining wind and wave energy inspired by hywind and wavestar

This article studies the feasibility of combining spar-type offshore wind turbine (inspired by Hywind) and a wave energy converter (inspired by Wavestar) by performing numerical simulations in operational conditions. The dynamic responses and power production of wave energy device and wind turbine are investigated for different power-take-off systems. Integrated/coupled aero-hydro-servo-elastic time-domain dynamic simulations considering multi-bodies are applied in this paper. The results show that by choosing proper power-take-off system, it is likely to minimize effects of wave energy convertor on floating wind turbine and hence maintaining the power performance of the wind turbine while getting more power through wave energy device.
