Wave Energy Converter Modeling in the Time Domain: A Design Guide

Creator:: Bosma, Bret
Abstract:: As the ocean wave energy field continues to mature, developers need a generic modeling methodology to test their designs before building prototypes. A design methodology for a first-pass time-domain simulation is a goal of this work. Built on results from the frequency domain analysis, the general procedure for obtaining time...

On the design, modeling, and testing of ocean wave energy converters

Creator:: Bosma, Bret
Abstract:: Ocean wave energy converter technology continues to advance and new developers continue to emerge, leading to the need for a general design, modeling, and testing methodology. This work presents a development of the process of taking a wave energy converter from a concept to the prototype stage. A two body...

Performance Analysis of a Utility-Scale Wave Energy Converter

Creator:: May-Varas, Nicholas A.
Abstract:: A six degree of freedom (6DOF) point-absorber wave energy converter (WEC) called LUPA is being developed at Oregon State University. This research focused on analyzing a full- scale LUPA, called LUPA20, to answer the following questions: 1) How does a full-scale WEC perform due to various factors; 2) What are...

Design and Simulation of Nonlinear Control Strategies for Heaving Point Wave Energy Converters in WEC-Sim

Creator:: Glennon, David N.
Abstract:: As the sources of our electricity shift from centralized and carbon emitting, to a portfolio of distributed, clean-energy sources, the wave energy converter (WEC) has become a topic of exploration and development for providing coastal communities electric power. Part of this trend has included an effort to create open source...

Hydrodynamic Modeling of Submerged Wave Energy Converters: Power Take-Off Mooring Configuration Effect on Power Performance

Creator:: Meek, Moira H.
Abstract:: Wave energy converters (WECs) show promising potential to significantly contribute to global renewable energy goals. Numerous WEC designs have been proposed and investigated, but wave energy conversion technology has yet to reach convergence in the same way wind or solar has. Of the designs currently in existence, surface-piercing WECs are...

Wave Tank Testing and Model Validation of an Autonomous Wave Energy Converter

Creator:: Bosma, Bret, Lewis, Tim, Brekken, Ted K. A., and von Jouanne, Annette
Abstract:: A key component in bringing ocean wave energy converters from concept to commercialization is the building and testing of scaled prototypes to provide model validation. A one quarter scale prototype of an autonomous two body heaving point absorber was modeled, built, and tested for this work. Wave tank testing results...

Comparison and Validation of Hydrodynamic Theories for Wave Energy Converter Modelling

Creator:: Leary, Matthew M.
Abstract:: A wide variety of hydrodynamic theories are utilized to approximate a Wave Energy Converter’s (WEC) equation of motion. Numerous theories have been refined in order to improve numerical approximations of WEC dynamics. When incorporating refined hydrodynamic theories into numerical models, there are distinct impacts on WEC rigid body motions, cable...

Application of Nonlinear Model Predictive Controller for Ocean Wave Energy Conversion Systems

Creator:: Haider, Ali S.
Abstract:: This work addresses the application of Nonlinear Model Predictive Control (NMPC) to a class of ocean wave energy conversion systems in which the cost functional is not in a standard quadratic form, and the WEC model includes the nonlinear effects, such as the hydrodynamic viscous drag. The NMPC implementation is...

Time-domain modeling of heaving point absorber wave energy converters, including power take-off and mooring

Creator:: Ruehl, Kelley
Abstract:: Wave energy conversion is still in its infancy, and in order for it to become a commercially viable technology, developers, investors and utilities need to estimate a Wave Energy Converter's (WEC's) performance for the wave climate of a potential installation site. With the goal of estimating a design's power output...
