Abstract
In recent years, with the excessive use of non-renewable energy sources, energy shortage has become a major problem for countries around the world, and the development of marine renewable energy has become urgent. As an important renewable energy source in the future, wave energy is one of our important research objects. This paper completes the design of the maximum wave energy output power and establishes the motion model of the float and the oscillator and the optimization model of the maximum average output power in the wave energy devices. This work helps people use wave energy reasonably and provides theoretical support for designing a new generation of wave energy equipment. In this paper, the motions of the float and oscillator in this wave energy device are modeled by Newton's theorem and Lagrange's equation, and then the displacement and velocity of the float and oscillator under the pendulum motion at different moments are solved by using the fourth-order Runge-Kutta method. The maximum average output power of the PTO system is solved by building an optimization model with a constant damping coefficient and a non-damping coefficient, followed by the traversal method and genetic algorithm.
