Adaptive vector control based wave-to-wire model of wave energy converters

This study presents a complete wave-to-wire model in which a novel wave energy converter control approach based on adaptive vector control is introduced. The proposed control for maximum power absorption of the primary resource is included, as well as the grid interconnection topology and required controllers, needed for processing the power over the entire wave energy conversion chain. Thanks ...

Optimum Control of Oscillation of Wave-energy Converters

The power output from wave energy converters (WECs) may be increased by controlling the oscillation in order to approach an optimum interaction between the WEC and the incident wave. Optimally controlled WECs, designed to operate at full capacity a rather large fraction of their lifetime, may improve the economic prospects for wave power significantly. Most of the WECs discussed here, utilise j...

Coordinated Control of Wave Energy Converters Subject to Motion Constraints

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...

Forecasting for Control and Environmental Impacts of Wave Energy Converters

This work is divided in to two distinct parts. In the first part a model is developed to assess the redistribution of wave energy about an offshore array of overtopping type wave energy converters. The model is based on a classical analytical solution for diffraction about a breakwater which is modified to consider an array of dissipating, reflecting and transmitting breakwater segments, which ...
