  • Bayesian Reinforcement Learning Based Control For Ocean Wave Energy Conversion

    Creator:
    Ghorban Zadeh, Leila
    Abstract:
    This work – in which three peer-reviewed academic papers are presented – addresses the ap-plication of Bayesian Reinforcement Learning to the control of a class of ocean wave energy conversion systems. The first paper presents a comparison of a Reinforcement-Learning (RL) based wave energy converter controller against standard Reactive Damping...

  • 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...

  • Ground Gen Airborne Wind Energy Conversion Systems: Tools for Conceptual Design and Rapid Prototyping

    Creator:
    Muschler, Alexander
    Abstract:
    Airborne Wind Energy System (AWES) are quickly coming to fruition, with increased energy production while reducing the cost of implementation and materials. This thesis develops a new computational model for a tethered AWES and characterizes a new rapid prototyping method with the objective of supporting the design and rapid prototyping...

  • 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...

  • Testing of wave energy converters using the Ocean Sentinel Instrumentation Buoy

    Creator:
    Lettenmaier, Terrance
    Abstract:
    Ocean testing of Wave Energy Converter (WEC) prototypes is necessary to facilitate commercial WEC development. The Ocean Sentinel Instrumentation Buoy, completed in August 2012, provides a stand-alone load for WEC prototypes during ocean testing. The first part of this work was to develop the power conversion and data acquisition equipment...

  • A methodology to enable wind farm automatic generation control

    Creator:
    Han, Hai-Yue
    Abstract:
    Over the last decade the increase in penetration of wind power and its variable nature has begun to add considerable stress to and threatened the stability of the nation's grid. In order to continue growth wind farms will need to have the ability to participate in the same grid frequency...

  • Sustainable building design framework : an integrated approach

    Creator:
    Piacenza, Joseph R.
    Abstract:
    This paper combines two research publications working toward the development of an integrated framework for commercial sustainable building design. Current methodologies utilize a traditional architectural top-down approach to sustainable building design practices that consumes financial and temporal resources early in the design process. By identifying the array mechanical subsystems required...

  • Design Optimization of a Structurally Flexible Wave Energy Converter with a Direct Search Algorithm

    Creator:
    Berrier, Austin S.
    Abstract:
    Several wave energy converter designs have been recently proposed that are made of flexible materials. Flexible devices are able to generate electricity by being stretched, and are intended to simplify deployment and maintenance concerns over existing wave energy devices. Due to the relative infancy of flexible wave energy converters, however,...

  • 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...
