  • 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...

  • Power system reliability and power quality assessments with grid-connected wave energy converters

    Creator:
    Boller, Michael D.
    Abstract:
    Generating abundant, renewable energy from Earth’s oceans is an attractive option for meeting increasing energy demand. Marine renewable energy also comes with the variability of renewable sources, which impact the reliability and power quality of the electrical grid. On a transmission-level, this dissertation looks at ensuring reliability of the power...

  • Zonal Resource Adequacy for Voltage Control

    Creator:
    Boller, Michael D.
    Abstract:
    In a power system, operators maintain voltage stability through adequate reactive reserves. Maintaining and accessing an efficient allocation of reactive reserves is prohibitively complex because of reactive line losses, the variety of reactive resources, and either limited or variable reactive outputs from renewable sources. By clustering the system into smaller...

  • 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...

  • Design and Implementation of a Frequency Controlled Electric Hot Water Heater Retrofit Thermostat

    Creator:
    Johanesen, Mackenzie S.
    Abstract:
    This design of a Grid Friendly Electric Hot Water Heater Thermostat was built for the Electrical and Computer Engineering Senior Design course, ECE44x. The design enables hot water heaters to respond to imbalances in the grid seen through deviations from standard grid frequency by varying the power output to the...

  • 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...

  • Design and Simulation of Nonlinear Control Strategies for Heaving Point Wave Energy Converters in WEC-Sim

    Creator:
    Glennon, David N.
    Abstract:
    As the sources of our electricity shift from centralized and carbon emitting, to a portfolio of distributed, clean-energy sources, the wave energy converter (WEC) has become a topic of exploration and development for providing coastal communities electric power. Part of this trend has included an effort to create open source...

  • Impacts of Prediction on Wave Energy Converter Control

    Creator:
    Comard, Colin Q.
    Abstract:
    Ocean waves provide a promising source of renewable energy for the North American electric grid. However, ideal control of wave energy converters (WECs) requires perfect forecasting of future wave conditions, and waves can be unpredictable. This paper presents a comparison of three different prediction methods and analyzes their performance in...

    AL-Anazi, Falah
    Abstract:
    The National Conference of State Legislatures NCSL declares that 29 states have been active in adopting and increasing renewable portfolio standards. Present renewable portfolio standards require utilities to increase integration of renewable energy sources such as photovoltaic (PV). The increased penetration of PV systems is expected to destabilize the power...
