Wave energy converters (WECs) require active control to maximise energy capture over a wide range of sea conditions, which is generally achieved by making the device resonate. The exaggerated device motion arising at resonance, however, may result in nonlinear effects that are ignored by the linear models that are typically employed. In particular, nonlinear viscous forces are significant for p...

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...

Wave energy is one of the most difficult energies to be captured among marine renewables. With technical progress, wave converters (WECs) are being tested in relatively deeper waters, which makes floating concepts almost only choice. In this paper, a two-body heaving WEC where absorbed through relative motion between outer annular and inner cylindrical buoys studied. Both experimental numerical...

This article presents an intelligent fuzzy logic controller (FLC) for controlling single-body heaving wave energy converter (WEC) or what is widely known as “Point Absorber”. The controller aims at maximizing the energy captured from the sea waves. The power take-off (PTO) limitations are addressed implicitly in the fuzzy inference system (FIS) framework. In order to enhance the WEC power captu...

Combing floating breakwaters with wave energy converters (WECs) and integrating them into very large structure (VLFS) can provide a viable option to explore economically offshore resources simultaneously protect marine structures. In this paper, the time-domain numerical model is developed based on modal expansion theory nonlinear consideration optimize design layout of an integrated system mod...

The oscillating water column wave energy converter (OWCWEC) is an established device which produces electricity by causing an ocean wave to drive air through a turbine. A system to control the operation can improve the device’s performance. In varying sea conditions, different objectives for control may be appropriate. For example, in some seas the controller might shut off the plant because th...

Wave energy can provide significant benefits as renewables acquire more share in electricity production. So far, focus for the development of wave is given to areas with resources ? 25 kW/m, moderate often not considered. Furthermore, waves have larger uncertainties associated diverse portfolio converters leading higher Levelized Cost Electricity (LCoE). This study challenges notion economic vi...

The wave energy converters are floating buoyance columns flexibly connected with the elastic platform. Hydrodynamic interactions among the colu...

The main purpose of this paper is to analyze the energy production in the Maltese islands, focusing on the employment of renewable energies in order to increase their energy independence. The main renewable source here proposed is wave energy: thanks to a strategic position, Malta will be able to produce electrical energy using an innovative type of Wave Energy Converter (WEC) based on the prot...
