  • 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...

  • Experimentation of Synchronous and Variable Speed Small Scale Hydropower Systems

    Creator:
    Jackson, Elliott C.
    Abstract:
    Hydropower is the one of the oldest renewable energy technologies and is wrongly thought of today as having little room to grow. The opportunity for new hydropower capacity is immense through both technology advancement and run-of-river new stream reach projects. Despite the age of hydropower, a divide in opinion is...

  • 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...

  • 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...

  • Computing Substation Fragility as a Function of Seismic Component Failure

    Creator:
    Stark, William D.
    Abstract:
    The electrical grid of the Western Interconnection is vulnerable to earthquake damage, especially large-magnitude megathrust events, due to the unique seismic profile of the region. However, the size of the Western Interconnection makes it difficult to model seismic failure in electrical substations to the level of detail necessary to improve...

  • A methodology to reduce the strain on hydro turbines using advanced life extending control of multiple energy storage systems

    Creator:
    Brosig, Sean G.
    Abstract:
    Over the last 20 years, there has been rapid growth in the amount of installed wind power in the Pacific Northwest, specifically in the Columbia River Gorge. The variable and non-dispatchable nature of this resource requires that it be balanced in some form by other sources on the grid. In...

  • 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...

  • Determining The Impact of Photovoltaic Generation on Power Systems

    Creator:
    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...

  • 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...

  • 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...
