Wave energy converter control by wave prediction and dynamic programming
We demonstrate that deterministic sea wave prediction (DSWP) combined with constrained optimal control can dramatically improve the efficiency of sea wave energy converters (WECs), while maintaining their safe operation. We focus on a point absorber WEC employing a hydraulic/electric power take-off system. Maximizing energy take-off while minimizing the risk of damage is formulated as an optima...
متن کاملNew 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...
متن کاملExperimental Evaluation of IRWEC1, a Novel Offshore Wave Energy Converter
This paper describes the innovative offshore point-absorber wave energy converter (WEC), IRWEC1, under development by the Hydrodynamics, Acoustics and Marine propulsion Group at Babol Noshirvani University of Technology. Totally enclosed in an outer shell, with no external moving parts, IRWEC1 is completely sealed which make it a robust and trustable system. Important motion for this WEC is the...
متن کاملStochastic Control of Inertial Sea Wave Energy Converter
The ISWEC (inertial sea wave energy converter) is presented, its control problems are stated, and an optimal control strategy is introduced. As the aim of the device is energy conversion, the mean absorbed power by ISWEC is calculated for a plane 2D irregular sea state. The response of the WEC (wave energy converter) is driven by the sea-surface elevation, which is modeled by a stationary and h...
متن کاملTurbine development for the Wave Dragon wave energy converter
The Wave Dragon is a wave energy converter of the overtopping type which has been developed by a European consortium during the last five years. It uses a set of low head water turbines as power takeoff system. In the course of a two year research programme the basic conception of the turbines has been established, the turbine geometry has been designed and a model turbine has been built and te...
