Comparison of Direct Drive Hydraulic and Dual-Stator Spoke Array Vernier Permanent Magnet Machines For Ocean Wave Energy Conversion

Creator:: Azam, Ridwan
Abstract:: Recently, there has been peaked interest in developing high energy producing and optimized power take-off topologies for Wave Energy Converters (WEC). As large as the potential of the oceans may seem, harnessing that energy and effectively converting it to electricity in significant amounts is a challenge. Currently, there are no...

Using EarthScope Magnetotelluric Data to Improve the Resilience of the US Power Grid: Rapid Predictions of Geomagnetically Induced Currents

Creator:: Bonner, L. Roy, IV
Abstract:: Geomagnetically Induced Currents (GICs) are quasi-DC signals that are induced in the ground during geomagnetic disturbances (GMDs) and pose a large threat to power grid infrastructure. The power industry currently attempts to mitigate GIC effects by utilizing 1-D ground electrical conductivity based electric field predictions, though conductivity can vary in...

Ocean Views: Characterizing Risk Perception, Uncertainty, and Decision-making Within the Ocean Condition Forecast System

Creator:: Kuonen, Jessica A.
Abstract:: Ocean users and marine scientists both have connections to the sea. This research explores how the nature of their connection to the sea leads to different perceptions of risk and comfort with uncertainty, and how these differences might be important to consider when one group has information another group needs....

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...

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 an Integrated Generator Power Take-of Strategy using Model Predictive Control (MPC) for Ocean Wave Energy Conversion

Creator:: Sundaram, Srinivasan Subhash
Abstract:: Model Predictive Control (MPC) has previously been investigated on ocean waveenergy converters (WEC) to improve the amount of power captured, while respectingthe system constraints. Previous research done in the same area, focused onbuilding a control scheme by using the knowledge of the past & current statesof the system and predicting...

Ground Improvement and Liquefaction Mitigation using Driven Timber Piles

Creator:: Gianella, Tygh N.
Abstract:: Seismically-induced liquefaction represents a major cause of damage to civil infrastructure and can result in significant damage following major earthquakes. Liquefaction can occur when earthquake ground motions raise pore-water pressures in loose, sandy soil, resulting in a substantial decrease of soil strength. Owing to the potential for instability following liquefaction,...

Aggregated reserve requirements of geographically diverse renewable portfolios in the Pacific Northwest

Creator:: Harpool, Scott E.
Abstract:: Increased penetration of renewable energy sources results in higher operating reserve requirements, due to the inherent variability and uncertainty of these resources. Many studies, primarily focusing on wind and solar, have determined that geographic diversity of variable renewables substantially reduces system variability and uncertainty. The Pacific Northwest is well suited...

Sizing and Performance of the Pendulum Power Take-Off Wave Energy Converter: Modularity and Chaotic Behavior

Creator:: Dizon, Chris
Abstract:: Multiple wave energy converter (WEC) archetypes exist with varying power take-off (PTO) designs in the attempt to maximize ocean energy harnessed and converted into useful energy. The pendulum PTO is popular for its simple, yet robust functionality due to its internally located components and simple operation. Additionally, this PTO does...
