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...

A Permanent-Magnet Linear Generator Wave Energy Converter for Low Power Ocean Sensors

Creator:: Miles, Lillian F.
Abstract:: Renewable energy sources are becoming increasingly important due to their low environmental impact and limitless nature. This thesis explores the design of a 250 mW permanent magnet linear generator wave energy converter to power ocean sensors. While many wave energy converters exist, this is a unique application because the wave...
Resource Type:: Masters Thesis

Dynamic Composite Load Signature Detection and Classification using Supervised Learning over Disturbance Data

Creator:: Tray, Kelly
Abstract:: Load modeling that can accurately represent the dynamic behavior of generators and loads is important in the operation and planning of transmission and distribution systems. Yet, it is a complex subject in power system research communities and electric utilities. The composition of the end-use loads is changing continually based on...
Resource Type:: Masters Thesis

Methodology for evaluating mechanical power in small-scale WEC experiments

Creator:: Simmons, Asher
Abstract:: Wave energy converters (WECs) are a broad class of emerging technology that converts hydrokinetic energy into some other useful form, such as electricity. The last stage in this transformation, the power take-off (PTO) subsystem, is often not experimentally evaluated until half-way through the recommended development process. This delay in evaluation...
Resource Type:: Dissertation

Applications of Nonthermal Microplasmas in Chemical Reaction Engineering

Creator:: Kreider, Peter B.
Abstract:: Nonthermal plasmas generate high concentrations of excited species that can simultaneously exist at high energy and far from thermodynamic equilibrium, making them useful tools in chemistry and engineering. Microplasmas, roughly defined as plasmas that are generated within sub-millimeter dimensions, provide enhanced stability, improved excited species density, increased nonequilibrium properties, higher...

RF Front End Tuning Methods for Wireless Power Transfer Systems

Creator:: Keskin, Nurcan
Abstract:: Wireless power transfer (WPT) is a way to transfer power from one device to another without any wire or cable connections. Although the technology has been around for more than 100 years, it is gaining popularity in recent years due to the ever-increasing demand for faster and more frequent charging...
Resource Type:: Dissertation

Development and Experimental Hardware Validation of Novel Variable Speed Hydropower Control Schemes for Emerging Applications and Water Resource Paradigms

Creator:: Starrett, Michael A.
Abstract:: Recent opportunities for new hydropower generation in the United States have often been in non-powered dams and run-of-river type flows occurring in low-impact natural areas and unregulated conduits. At the same time, a changing water resource paradigm is challenging some existing generation in drought stricken areas where supply reservoirs behind...

Rapid Grid State Estimation using Singular Value Decomposition

Creator:: Kulkarni, Janhavi
Abstract:: Synchrophasor technology has gained great momentum with the widely adopted concept of smart grids in power systems at transmission and generation level. This has led to an improved state estimation of a power system with the advent of Phasor Measurement Units (PMU). PMUs contribute in providing real-time information about the...
Resource Type:: Masters Thesis

Extended Kalman Filter Simulink Model for Nonlinear System Modeling

Creator:: So, Ratanak
Abstract:: The objective of the work presented herein is the development of the extended Kalman filter for nonlinear system modeling. A standard Kalman filter is a well-known filter for estimating the state of a system, assuming the system is linear and it has a Gaussian distribution in its noise. In reality,...
Resource Type:: Masters Thesis

A Microgrid Design Case Study : Synchrophasor Placement and Development of a Protection Laboratory for the Oregon State University - Corvallis Campus

Creator:: Huo, Chen
Abstract:: In the past two years, Oregon State University (OSU) Corvallis campus suffered several power outages. The estimated cost of one of those outages was close to a million dollars worth of equipment and impact on research projects. Meanwhile, the campus grid operates with severely aging power assets. The reliability of...
