This article proposes a non-linear vibro-impact mechanism, integrated inside semi-submerged cylindrical buoy to form self-contained and self-referenced wave energy converter (VIWEC), for performance enhancement. A mathematical model of the VIWEC is derived, considering linear wave-buoy interaction mechanics. Numerical simulations are conducted investigate influence mechanism on VIWEC's dynamics...

This paper concerns the absorption of energy from two-dimensional water waves propagating over fluid constant depth by a wave converter consisting small buoyant floating rafts constrained to move in heave motion and attached bed with springs dampers. Under shallow approximation motion, it is shown that spatially-varying spring damper settings allow all be absorbed frequencies. The basis design ...

Harvesting energy from ocean waves remains an untapped resource, and it is considered a new methodology in renewable energy, especially Malaysia. This research based on project at Kuantan Port that used Wave Energy Converter (WEC) as platform to generate convert into electricity. The purpose of this conduct risk assessment before the execution by referring International Organization for Standar...

Abstract: In this paper, a generic coordinated control method for wave energy converters is proposed, and the constraints on motion amplitudes and the hydrodynamic interaction between converters are considered. The objective of the control problem is to maximize the energy converted from ocean waves, and this is achieved by coordinating the power take-off (PTO) damping of each wave energy conve...
