Abstract
To improve the efficiency of the floating wave energy converters arrays, the genetic algorithm is used to optimize the 2-DOF floating wave energy converters arrays. In this paper, the 2-DOF wave energy converter and its array mathematical model are first introduced, and then the study on the construction of 2-DOF device array optimization model and its genetic algorithm solution is conducted. On this basis, the arrangement optimization calculation of 2, 3 and 5 device arrays with the area of 100 m×100 m sea area is carried out respectively. Furthermore, the optimization results of two device arrays are verified, and the mechanism for the increase of the interaction factor q of wave energy converters arrays is analyzed. The results show that the genetic algorithm can effectively optimize the array arrangement of 2-DOF devices, enhance the interaction between the devices in the array, and improve the power generation efficiency of wave energy converters arrays.
