To implement China's maritime power strategy, the development and utilization of wave energy technology has progressed rapidly. Among these, hydraulic wave energy power generation technology holds advantages for large-scale development. However, this technology still faces the issue of discontinuous power output, making the electricity difficult to utilize. To address this, a hydraulic system energy storage and energy conversion control model was constructed. Analysis revealed that the fundamental reason for the discontinuous total power generation under the current hydraulic autonomous control valve method is that the generator's start and stop times are not adjusted in real-time according to the current wave energy size, failing to utilize the energy storage capacity of the hydraulic system. A method was proposed to predict wave energy in real-time and dynamically calculate the generator's start-stop pressure setpoints and operation times. Through simulation experiments, the number of interruptions in wave energy power generation was significantly reduced, and the fluctuation amplitude decreased, achieving continuous and stable power output. This lays a solid foundation for subsequent electrical energy conversion.
