Efficient Electrical Power Improvement by Oscillating Buoy Wave Energy Converter

The oscillating buoy wave energy converter which includes output power, annual electricity production and energy conversion efficiency. It is helpful to the performance test of the device and contributes to the dispatch control of the complex power and the study of the stability of the local power grid. To derive the prediction models, it is necessary to analyze the force on the buoy and the heaving motion. On this basis the torque and rotating speed models are given. Then the output power, annual electricity production and energy conversion efficiency models are built. Wave data are imported into the models to be simulated with MATLAB and the predicted values are obtained. Finally, the model of the wave energy converter integrated into power grid is built with Simulink and the results of the simulation verify the correctness of the previous models
