“…From Figure 6(a) it can be seen that, in the range of [1, 3] m, the larger the radius of the buoy, the more wave energy it captures, which agrees with the conclusion in Ref. [4] for the constant draft to radius ratio. In addition, it is found that the range of wave frequencies considered is 0.2–0.3 Hz.…”

“…Many different types of WECs have been designed, but only a small proportion of these have reached the full‐scale prototype stage so far [2]. Among the various forms of WECs, point absorber WECs have attracted extensive attention because of their simple structure and high conversion efficiency [4], which consist of single‐body and two‐body point absorber types.…”

The parametric study and optimization of a two-body wave energy converter (WEC) for the wave and current conditions in the region of Zhaitang Island (China) is presented. Nine parameters are considered, and their influence on the power captured by the two-body WEC is investigated following both single-parameter and multi-parameter approaches. A backpropagation neural network model is developed and applied to predict the captured power for any given values of the nine parameters and the wave frequency. Then the robust design method, also known as the Taguchi method, is implemented to study the comprehensive effects of the parameters on the power output of the device. Moreover, scale model experiments are conducted to verify and confirm the influence of the principal parameters on the power output. Combining numerical simulations, a neural network model and experimental work, this study provides an optimization programme for the main parameters of the device in the target sea region and, at a more general level, references for two-body WEC designs based on specific sea states.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Furthermore, they found that increasing the mass of the float did not have a meaningful effect on the power output of the WEC (Erselcan and Kükner, 2020). Gomes et al optimized the hull design of a two-body point absorber using a GA to maximize the extracted energy, but the obtained dimensions of the WEC were impractical.…”

“…Considering the design constraints, the dimensions of the WEC hulls were optimized mainly to improve the performance and reduce the hull size, i.e., cost. Results showed that geometry optimization could significantly improve the absorbed energy (Esmaeilzadeh and Alam, 2019;Gomes et al, 2012;Renzi et al, 2017;Colby et al, 2011). If the PTO control strategy is optimized simultaneously with the geometry using multi-objective optimization, it may result in better solutions (Garcia-Teruel and Forehand, 2021b).…”

“…The authors apply numerical modelling in order to optimize the diameter and draft of the cylindrical buoy, using the wave data for nearshore region of Rio de Janeiro, Brazil. Point absorber with floating buoy and hydraulic power take-off system are studied in [4]. In this study a parametric optimization is carried out to find an optimal design for maximum energy harvesting in a target area off the Turkish coast of the Black Sea.…”

In this work, a single degree of freedom resonant converter model is proposed and theoretical studies of the converter are carried out. The converter is suitable for waves with height of up to 2 m and period of up to 5 seconds, such as the waves on the western coast of the Black Sea. It is shown that at resonance its power increases significantly and approaches the theoretical values of the power of the swell. In high waves (up to 5 m) its efficiency decreases, but its power remains relatively constant and equal to about half of its power at resonance.
