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...

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...

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...

Impacts of Prediction on Wave Energy Converter Control

Creator:: Comard, Colin Q.
Abstract:: Ocean waves provide a promising source of renewable energy for the North American electric grid. However, ideal control of wave energy converters (WECs) requires perfect forecasting of future wave conditions, and waves can be unpredictable. This paper presents a comparison of three different prediction methods and analyzes their performance in...

A remotely operated, autonomous wave energy converter system

Creator:: Lewis, Timothy M.
Abstract:: The potential for electric energy generation from ocean waves is substantial and much research is being conducted on the conversion process as a renewable, grid-connected, power source. Some of the same attributes that make wave energy harvesting attractive as a grid-connected source also make it attractive as a remote, or...

Development of adaptive damping power take-off control for a three-body wave energy converter with numerical modeling and validation

Creator:: Zhang, Zhe
Abstract:: The performance of the power take-off (PTO) system for a wave energy converter (WEC) depends largely on its control algorithm. This paper presents an adaptive damping control algorithm that improves power capture across a range of sea states. Validation for the numerical model was performed using data from two sources;...

Validation of Wave Energy Converter Models and the Development of Control Strategies in WEC-Sim

Creator:: So, Ratanak
Abstract:: When the term renewable energy is mentioned in a conversation, wind, solar, and hydro energy typically come to mind. However, there is one major resource that has remained mostly untapped: wave energy. Wind and solar power technologies are well established around the world but they cannot generate electricity all the...
