Research on how the arrangement of arrayed PA-WECs influences to their electric power generation

This paper describes the relationship between an arrangement of Point Absorber Wave Energy Converter (PA-WEC) and power generation. In an array of PA-WECs, complex hydrodynamic interaction occurs. The interaction affects both increase and decrease of wave power density among PA-WECs. When aiming to maximize the generated electric power, it is necessary to appropriately select the control force of the generator in consideration of the positive effect of hydrodynamic interaction. This paper presents a numerical solution of the control force parameter for maximizing the generated electric power of the multi PA-WECs, taking into account the hydrodynamic interaction among PA-WECs in both diffraction and radiation problems. Then, numerical studies are carried based on the proposed method. From these results, the effects of the distance between PA-WECs and the number of PA-WECs in a linear arrangement on the generated electric power are discussed. In addition, the sensitivity of the arrangement of PA-WECs to the generated electric power is considered.
