This thesis presents a method for capturing the sea wave energy by using an integrated flywheel and generator. The suggested method reduces the torque and voltage fluctuations following the sea wave fluctuations. The sea waves are the huge source of renewable energy that can be justify; LINE-HEIGHT: normal; MARGIN: 0cm 0cm 8pt" The validity of the model and performance of the suggested algorithm are verified and evaluated through simulation of a sea wave energy harvester with practical data. The simulation results confirms the validity of the model by comparing the dynamic test results with available test results of a buoy. It also shows the capability of the suggested algorithm in tracking of the maximum power point, corresponding to a sea wave with a sinusoidal pattern.
