| Outline of Final Research Achievements |
In this study, a hybrid wind-wave energy system was proposed. Firstly, a low cost semisubmersible in which wave energy converter can be installed was designed, and the stability of the floating wind turbine and the motion characteristics were analyzed. Secondly, an oscillating-water-column type wave energy converter which can be easily mounted on the semisubmersible was developed and the mathematical model was studied. Then, a 1/100 small scale model was designed and water tank tests were carried out to evaluate the performance of the numerical model. Finally, a model-based controller for wave energy converter was developed to reduce the motion of floating platform. Simulation results verified the good performance of the controller. Owing to the scaling problem that the mass of power-take-off of wave energy converter cannot be designed, and the performance of the controller was not verified by experiments.
