Perspectives on Damping Strategy for Heaving Wave Energy Converters

Systematic Design of a Heaving Buoy Wave Energy Device

Oscillating type devices constitute a major class of offshore wave energy converters. In view of the characteristic of the wave energy in China that is low in energy density, a new heaving buoy wave energy device is designed. The paper introduces the basic components of the device, including buoys, support platform, submerged platform, anchor system and hydraulic power take-off, addresses the s...

Grid Connection Improvements by Control Strategy Selection for Wave Energy Converters

In this paper a wave-to-wire approach to model the exploitation of ocean energy by point absorbers in heave is presented. Attention is focused on the impact that the control strategy of the Wave Energy Converter (WEC) has both on the power performance of the single device and on the grid power quality at the connection point, when point absorbers are arranged in wave farms. Two different contro...

New Perspectives on Wave Energy Converter Control

This work examines some of the fundamental problems behind the control of wave energy converters (WECs). Several new perspectives are presented to aid the understanding of the problem and the interpretation of the literature. The first of these is a group of methods for classifying control of WECs. One way to classify control is to consider the stage of power transfer from the wave to the final...

Interactions Between an Oscillating Wave Surge Converter and a Heaving Wave Energy Converter

In this paper, we investigate the mutual hydrodynamic interactions between two different kinds of devices, namely, an Oscillating Wave Surge Converter modeled as an oscillating flap and a generic Heaving Wave Energy Converter modeled as a vertical truncated cylinder. A three-dimensional mathematical model based on linear potential flow theory is developed. It is assumed that the effects of the ...
