  • 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...

  • 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...

  • Dynamic modeling and mitigation of cascading failure in power systems

    Creator:
    Song, Jiajia
    Abstract:
    Recent blackout events consistently show that a variety of mechanisms are involved in cascading outages. These cascading mechanisms are irregularly modeled and validated within the existing literature and industry practices. Understanding the relative significance of these different mechanisms is important for choosing which one(s) needs to be modeled for specific...

  • A multiscale approach to bacterial adhesion

    Creator:
    Ostvar, Sassan
    Abstract:
    This work is an attempt to develop a simple physical description for the initial interactions between a bacterial cell and a substrate surface. This is done by adopting a view that regards bacterial surface biomolecules not as secondary and add-on contributors to the potential energy function that characterizes the overall...

  • 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...

  • 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...

  • 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,...

  • 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...

  • 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...

  • Static and cyclic response of ecoroof soil

    Creator:
    Kraupa, Travis J.
    Abstract:
    Green technology in the United States has been on the rise over the past few decades in the United States. However, certain green technologies have been developed in the absence of design standards. Ecoroofs, which are vegetated soil masses placed on the top of a building’s roof structure, present several...
