TL;DR: In this article, the mean annual power absorption of a selection of eight Wave Energy Converters (WECs) with different working principles is derived based on numerical modeling. But, despite very different working principle and dimensions, power performance of the selected devices vary much less than the average power absorption.

TL;DR: In this paper, the authors focus on two aspects of systems for wave energy conversion: how to model such systems, and how to control their motion, which is crucial for the primary power conversion.

TL;DR: Two different upper bounds for absorbed power are applied in a ‘Budal diagram’ and it appears that, for a single WEC unit, a power capacity of only about 0.3 MW matches well to a typical offshore wave climate, and the full physical volume has to be significantly larger than the swept volume, unless phase control is used.

TL;DR: In this paper, an oscillating water column (OWC) inside a fixed vertical tube of small circular cross-section was tested by small-scale testing and the results showed that phase control may substantially increase the power absorption in point-absorber wave energy converters.
