Wave Energy Linear Generator System Including a Newly Designed Wave Roller Mechanical Interface

As the demand for energy continues to grow and global climate change intensifies, prompting countries to reduce carbon emissions, wave energy generation has shown significant potential. This paper introduces a novel wave energy device incorporating a wave roller, based on the classical direct float linear generator structure, with optimizations made to its key components. The novel generation device reduces the required mover stroke in the linear generator, thereby decreasing the overall size of the system and minimizing the uncertainty of the mover’s trajectory. Additionally, the device can accommodate multiple linear generators for combined operation, enhancing the utilization of wave energy captured by a single float. Finally, the practicality of the device is demonstrated through MATLABR2021b/Simulink simulation and experimental validation.
