  • Risk and Uncertainty Quantification Methods in Electrical Power Systems

    Creator:
    Johnson, Brandon S.
    Abstract:
    Load flow studies are one of the most essential engineering applications for grid operators because they provide a clear picture of the operating conditions of the power system. Traditionally, the load flow problem is assumed to be deterministic; that is, the system variables contain no randomness. Unfortunately, this assumption is...

  • Partitioning Techniques to Improve Resilience and Cyber Security in Electric Grid Infrastructure

    Creator:
    Huo, Chen
    Abstract:
    With the increasing penetration of renewable energy integration and potential threats from natural disasters, modern electric power system have been significantly exposed to both small- and large-scale disturbances. Traditional performance metrics including indices of reliability, stability, and security are no longer adequate to describe a power network. Infrastructure properties like...

  • Development of Machine Learning Tools for Increased Reliability of the Electrical Grid

    Creator:
    Dieter, Keaton J.
    Abstract:
    The electrical grid serves as one of the major lifelines to our society. We have come to expect electricity to be available when we want it. But the system that delivers power to us is very complex and made up of many individual pieces. Maintaining and operating this system reliably...

  • Dynamic Load Model Placement and Development with Case Study of Microgrid in Nome, Alaska

    Creator:
    Cicilio, Phylicia
    Abstract:
    Dynamic modeling is key to the successful operation and reliability of electrical grids by evaluating transient stability. Developing dynamic load models and identifying where they are necessary is a challenging task as loads are an aggregation of individual devices that change throughout the year. This thesis investigates how to develop...

  • Evaluating the Effects of System Operators’ Response on the Propagation of PowerSystem Cascading Failures

    Creator:
    Hennessy, Conor F.
    Abstract:
    The majority of power system cascading models assume that system operators will react perfectly and timely to an electrical event. However, as evidenced by several blackouts in the last decades, the inadequate system operators’ situation awareness and response can contribute significantly to the severity of an electrical disturbance. Under these...

  • Toward Automated Decision-Making in Power Systems Wide-Area Protection

    Creator:
    Meier, Richard John
    Abstract:
    In recent years there have been many improvements in the reliability of critical infrastructure systems. Despite these improvements and despite targeted efforts to improve the operation and control of the electric grid, the power systems industry has seen relatively small advances in this regard. For instance, today's power system is...

  • Bitmap Indexing : Energy Applications and Improvements

    Creator:
    McCamish, Benjamin
    Abstract:
    Large databases and data warehouses are becoming prevalent for the storage and management of energy data. Accelerating the rates at which data can be retrieved is beneficial not only to allow for more efficient search of the data, but also to be integrated with other energy system tools. In this...

  • 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...

  • Power Grid Modeling Using Graph Theory and Machine Learning Techniques

    Creator:
    Duncan, Daniel
    Abstract:
    Graphs have a wide variety of real-world applications. In the area of social networks, graphs are composed of individuals and their relationships with others. Analysis of social networks led to the discovery of the small-world phenomena, which is also known as six degrees of separation. Our analysis is focused on...

  • Usable and Scalable Querying of Scientific Datasets

    Creator:
    McCamish, Benjamin J.
    Abstract:
    Scientists and engineers have to analyze and query multiple large databases. Analysis over databases created by phasor measurement units can provide insight into the health of the grid, thereby improving control over operations. Realizing this data-driven control, however, requires validating, processing and storing massive amounts of PMU data efficiently, which...
