  • 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...

  • Modeling, simulation, and analysis of two hydraulic power take-off systems for wave energy conversion

    Creator:
    Casey, Sean (Sean Michael)
    Abstract:
    Hydraulic power take-off (PTO) systems have been implemented in several wave energy converter (WEC) designs in recent years. Two popular hydraulic PTO configurations coupled to a point absorber hydrodynamic model are simulated in waves representative of an energetic sea state likely to be found in deep waters off the coast...

  • Predicting deep water breaking wave severity

    Creator:
    Hovland, Justin
    Abstract:
    Ocean Wave Energy Converters (WECs) operating on the water surface are subject to storms and other extreme events. In particular, high and steep waves, especially breaking waves, are likely the most dangerous to WECs. A method for quantifying the breaking severity of waves is presented and applied to wave data...

  • Real-Time Estimation and Prediction of Wave Excitation Forces for Wave Energy Control Applications

    Creator:
    Ling, Bradley A.
    Abstract:
    Wave energy is emerging as a new potential source for renewable energy generation. However, wave energy technology is not currently cost competitive with other more mature renewable energy sources such as wind and solar. One approach that researchers and developers are taking to reduce the cost of wave energy is...

  • Wave Energy Converter Array Optimization : Algorithm Development and Investigation of Layout Design Influences

    Creator:
    Sharp, Christopher J.
    Abstract:
    Realizing the vast amount of energy available in ocean waves, an industry has emerged that is progressing towards the deployment of grid–connected wave energy converters. Likely to be deployed in arrays, a challenge to the wave energy industry is maximizing the energy production of such arrays. We have been developing...

  • A Conceptual Design Tool for High-performance Wave Energy Converters for Blue Economy Applications

    Creator:
    Roach, Aeron L.
    Abstract:
    Much like wind energy in its early years, marine energy has vast potential, and wave energy converter (WEC) concepts are constantly in development. Consequently, wave energy faces many challenges for expansion and has a wide-ranging design space of WEC concepts. The large design space demands new methods for understanding the...

  • The effects of ocean variability and breaking waves on wave energy converter reliability and survivability

    Creator:
    Brown, Adam
    Abstract:
    The reliability and survivability of a wave energy converter (WEC) is highly dependent on the variability and non-linearity of the ocean itself. Ocean variability occurs on many time scales. Climate variability occurs decade-to-decade, and year-to-year in the number and intensity of winter storms. Seasonal variation of wave height and period...

    Creator:
    Boren, Blake C.
    Abstract:
    Presented is an investigation into the modeling, active control design, and simulation of a generic horizontal pendulum wave energy converter, known as a PWEC. A description is provided of the dominant attributes PWECs have, showcasing their promising potential as wave energy converters. Seeking to further promote this potential, an active...

  • Towards reliable and survivable ocean wave energy converters

    Creator:
    Brown, Adam C.
    Abstract:
    Ocean wave energy is a new and developing field of renewable energy with great potential. The energy contained in one meter of an average wave off the coast of Newport Oregon could supply dozens of homes with electricity. However, ocean waves are usually quite irregular which leads to large bursts...

  • Optimizing ballast design of wave energy converters using evolutionary algorithms

    Creator:
    Colby, Mitchell
    Abstract:
    Wave Energy Converters (WECs) promise to be a viable alternative to current electrical generation methods. However, these WECs must become more efficient before wide-scale industrial use can become cost-effective. The efficiency of a WEC is primarily dependent upon its geometry and ballast configuration which are both difficult to evaluate, due...
