Research on the Output Power Model of PTO System Based on Golden Division Method and GA

The wave energy device is an energy conversion device that can utilize wave energy from marine renewable energy sources. In this paper, based on the float and oscillator motion model, the value of the damping coefficient is expanded to an optional interval. Secondly, according to the definition of power, the equations of the average output power and linear damping coefficient of the PTO system are derived, the optimization model is constructed, and the maximum output power and the corresponding linear damping coefficient are obtained by using the golden partition method and the genetic algorithm in the one-dimensional search algorithm to solve respectively. In this paper, two different algorithms are used according to the functional characteristics of the output power model of the PTO system in different cases, which reduce the amount of operations while ensuring a more accurate solution.
