Wave energy, as a novel form of renewable energy, holds promising potential for efficient electricity generation. Regarding oscillating buoy-type wave energy converters, many countries have already put prototypes into use, indicating a broad technological outlook for wave energy utilization. This study introduces an array float type wave energy generation system, develops a three-dimensional model of an individual buoy, and evaluates the buoy’s vertical motion response characteristics at varying draft depths using the hydrodynamic analysis software AQWA. Subsequently, finite element analysis is employed to appraise the structural integrity of the buoy. The wave energy generation system featuring array buoys undergoes power generation simulation using Matlab/Simulink, furnishing valuable data for the advancement of such systems.
