Sustainability of the Renewable Energy Extraction Close to the Mediterranean Islands

open access: yesEnergies, 2017
The aim of this work is to explore the possibility of transitioning a fuel powered island to a renewable powered one. This transition is analyzed for the real MV/LV distribution system of the island of Pantelleria, in the Mediterranean Sea. Particularly,

Point absorber wave energy converters in regular and irregular waves with time domain analysis [PDF]

open access: yes, 2016
A discrete control of latching is used to increase the bandwidth of the efficiency of the Wave Energy Converters (WEC) in regular and irregular seas. When latching control applied to WEC it increases the amplitude of the motion as well as absorbed power.

Investigation of Vertical Slamming on Point Absorbers [PDF]

open access: yesVolume 6: Nick Newman Symposium on Marine Hydrodynamics; Yoshida and Maeda Special Symposium on Ocean Space Utilization; Special Symposium on Offshore Renewable Energy, 2008
This paper focuses on the impact of vertical slamming on floating point absorber systems and the associated pressures that might be expected when these phenomena occur. In a first part it will be shown how the occurrence probability of slamming can be reduced by implementing a slamming restriction, i.e.

A Flexible Chain Proposal for Winch-Based Point Absorbers

open access: yesJournal of Mechanical Design, 2018
Ocean wave power is a promising renewable energy source. It has, however, been difficult to find a cost-effective solution to convert wave energy into electricity. The harsh marine environment and the fact that wave power is delivered with large forces at low speed make design of durable mechanical structures and efficient energy conversion challenging.

Bottom slamming on heaving point absorber wave energy devices [PDF]

open access: yesJournal of Marine Science and Technology, 2010
Oscillating point absorber buoys may rise out of the water and be subjected to bottom slamming upon re-entering the water. Numerical simulations are performed to estimate the power absorption, the impact velocities and the corresponding slamming forces for various slamming constraints.

Degrees of freedom effects on a laboratory scale WEC point absorber

open access: yesInternational Marine Energy Journal
There are many archetypes of wave energy converters (WEC) that vary widely in operating principles, geometry, controls, number of bodies, and degrees of freedom (DOF).

Optimal Constant DC Link Voltage Operation of aWave Energy Converter

open access: yesEnergies, 2013
This article proposes a simple and reliable damping strategy for wave powerfarm operation of small-scale point-absorber converters. The strategy is based on passiverectification onto a constant DC-link, making it very suitable for grid integration of the

Cost-Based Design and Selection of Point Absorber Devices for the Mediterranean Sea

open access: yesEnergies, 2018
Sea wave energy is one of the most promising renewable sources, even if relevant technology is not mature enough for the global energy market and is not yet competitive if compared with solar, wind and tidal current devices.

Research on vibration reduction performance of dynamic vibration absorber based on damping characteristic of a new material

open access: yesAdvances in Mechanical Engineering, 2020
The absorbing effect of traditional dynamic vibration absorber (TDVA) is satisfactory only when the natural frequency is close to the excitation frequency.
