  • 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...

  • 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...

  • Methods for evaluating the impact of renewable resource variability on grid operation and planning

    Creator:
    Halamay, Douglas A.
    Abstract:
    With the recent interest in increasing the penetration of renewable energy sources onto the power grid, there has been an unprecedented rapid deployment of wind generation, especially in the US Pacific Northwest. While wind farm developers have continued to expand their operations, power system operators are left to deal with...

  • Residential load simulation and applied load management strategies

    Creator:
    McArthur, Shaun
    Abstract:
    This work presents a residential load simulation framework that allows the user to test the effectiveness of peak reduction, peak shifting, and valley filling load management strategies on a representative residential load prior to physical smart sensor and load control deployment. The simulation methodology uses household occupancy, appliance time-of-use, and...

  • A linear test bed for characterizing the performance of ocean wave energy converters

    Creator:
    Hogan, Peter M.
    Abstract:
    Determining the performance characteristics of various ocean wave energy converters (OWEC) has proven to be difficult due to problems replicating a baseline motion profile in the ocean or wave tank to compare these devices. The linear test bed seeks to mechanically simulate the relative linear motion between the active components...

  • 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...

  • Evaluating the seismic risk and resilience of an electrical power system

    Creator:
    Chalishazar, Vishvas H.
    Abstract:
    The Pacific Northwest is part of the "Ring of Fire," which is well-known for heavy seismic activity. Numerous active faults in the area have encouraged electric grid managers in the region to more deeply contemplate and proactively intervene to support grid resilience. This research introduces Monte Carlo (MC) based power...

  • Computing Substation Fragility as a Function of Seismic Component Failure

    Creator:
    Stark, William D.
    Abstract:
    The electrical grid of the Western Interconnection is vulnerable to earthquake damage, especially large-magnitude megathrust events, due to the unique seismic profile of the region. However, the size of the Western Interconnection makes it difficult to model seismic failure in electrical substations to the level of detail necessary to improve...

  • Development of a Hybrid Simulation for an Ocean Wave Energy Converter

    Creator:
    Harris, Jesse
    Abstract:
    Ocean Wave Energy Converters (WECs) are of interest around the globe as global economies begin to shift their interest to renewable forms of energy. However, the devices are costly to construct–a quality that can be relieved through proper modeling, control, and implementation. This paper presents the numerical and hybrid simulation...

  • 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;...
