A point absorber is a device converting the sea wave energy into electricity (WEC). Its movement in the vertical direction captures the main part of the absorbed power. In order to get power from other oscillation modes, more tethers have been added in the studied device. After a system's linearization with Taylor's expansion, an analysis in function of the moorings length and the incoming wave frequency was done. Using a MATLAB optimization process, the parameters which maximize the extracted power were found in each case. Furthermore, a comparison among this device and a single tether one is presented. The proposed WEC can achieve up to 50% more power production than generic point absorbers.

Abstract
A point absorber is a device converting the sea wave energy into electricity (WEC). Its movement in the vertical direction captures the main part of the absorbed power. In order to get power from other oscillation modes, more tethers have been added in the studied device. After a system's linearization with Taylor's expansion, an analysis in function of the moorings length and the incoming wave frequency was done. Using a MATLAB optimization process, the parameters which maximize the extracted power were found in each case. Furthermore, a comparison among this device and a single tether one is presented. The proposed WEC can achieve up to 50% more power production than generic point absorbers.| File | Dimensione | Formato | |
