Research on one-dimensional wave energy output power based on differential control and particle swarm optimization

Wave energy, as an important marine renewable energy source, has considerable application prospects, and its energy conversion efficiency is one of the key issues for the large-scale utilization of wave energy. For the wave energy device with given specifications, this paper investigates the motion law of float and oscillator under different oscillation modes and the output power variation of PTO system by establishing a mathematical model. In this paper, combining the basic laws of Newtonian dynamics, a one-dimensional forced vibration model is established in the form of a two-dimensional system of differential equations by analyzing the forces on the float and the oscillator. On this basis, this paper uses Runge-Kutta algorithm to solve the system of differential equations, and obtains the motion law of float and oscillator, and outputs the graphs of its displacement and velocity variation with time. In this paper, the single objective optimization model is solved by Monte Carlo simulation and particle swarm algorithm to obtain the optimal damping coefficient of the linear damper when the average output power of the system is maximum.
