  • 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...

  • 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...

  • Simplified WECC modeling for frequency response, wind integration, and energy storage

    Creator:
    Bhattacharji, Pranathi
    Abstract:
    The primary objective of a grid is to maintain a balance between generation and load. If these quantities are not in balance with each other, severe damages such as voltage fluctuations, low power quality, power outages or even cascaded blackouts may occur. Hence one of the primary factors that holds...

  • Digital simulation of a load-peaking generation station located in a tidal estuary

    Creator:
    Husband, James Harris
    Abstract:
    This simulation is a model for a tidal power-peaking plant that can be used to determine the electrical peaking generation for a given set of conditions. The simulation internally contains a tide producing function for a specific year, the hydraulic characteristics of the plant, and the plant's machines' characteristics. The...

  • Nonlinear neural control with power systems applications

    Creator:
    Chen, Dingguo
    Abstract:
    Extensive studies have been undertaken on the transient stability of large interconnected power systems with flexible ac transmission systems (FACTS) devices installed. Varieties of control methodologies have been proposed to stabilize the postfault system which would otherwise eventually lose stability without a proper control. Generally speaking, regular transient stability is...

  • Exploring security metrics for electric grid infrastructure leveraging attack graphs

    Creator:
    Patapanchala, Panini Sai
    Abstract:
    Electric grid is a critical cyber-physical infrastructure that serves as lifeline for modern society. With the increasing trend of cyber-attacks, electric grid security has become a significant concern. Electric grid operators are working hard to reduce the risk of these attacks towards the system. Having security metrics for monitoring the...

  • Design of robust infrastructure systems incorporating user behavior

    Creator:
    Piacenza, Joseph R., III
    Abstract:
    Infrastructure systems are a critical component supporting today's modern society. From power grids to traffic networks, we rely on these systems to perform as intended, despite the various sources of uncertainty present in their operation. Designing for system robustness can help mitigate the impact of failures caused by unexpected events....

  • Development of biomimetic control strategies for the optimal use of renewable sources and energy storage systems

    Creator:
    Hapke, Hannes Max
    Abstract:
    In the year 2007, the worldwide energy consumption accumulated to a total of 16.5 billion MWh. While the resources of conventional energy production cause environmental damage, renewable energy sources like solar or wind power offer a solution to substitute for coal or nuclear generated power. Countries like Denmark and Spain...

  • Proof of concept of the use of RAVEN and RELAP5-3D for risk informed safety margin characterization

    Creator:
    Riley, Thomas H.
    Abstract:
    This project was a proof of concept of the use of the RAVEN software, a tool developed for the Risk Informed Safety Margin Characterization (RISMC) approach, with RELAP5-3D. This novel approach combines older probabilistic and mechanistic approaches to look at how and why the complex systems of a nuclear power...
