  • DC notch filter offset cancellation for direct-conversion receivers

    Creator:
    Pan, Dongling
    Abstract:
    Direct-conversion architecture would dominate the modern low power wireless receiver architecture if problems such as offset cancellation, even-order distortion, and flicker noise were solved. Among those problems, offset is the most serious one. This thesis will discuss and analyze one approach to cancel offsets in direct-conversion receivers. First, we explain...

  • Efficient RF energy scavenging and ultra-low power management for powering wireless sensor nodes

    Creator:
    Arumugam, Vikrant P.
    Abstract:
    As the demand for real-time information in engineering and health care systems keeps increasing, the need for wireless sensor nodes is also continuously increasing. As a result, the cost and effort involved in installing and maintaining batteries to power the numerous sensor nodes is growing exponentially. Providing a cost effective...

  • Analysis and optimal sizing of an energy storage system for wind farm applications

    Creator:
    Yen, Zuan Z.
    Abstract:
    Modern wind energy is the technology of choice with a short payback period for increasing renewable energy portfolios. Bonneville Power Administration (BPA), a United States power authority in the Pacific Northwest expects to increase their wind energy capacity from 2,000 megawatts to 6,000 megawatts within the next five years. Currently...

  • 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 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...

  • Methods for short-term prediction of wind speeds in the Pacific Northwest Columbia Gorge wind farm region

    Creator:
    Davidson, James D.
    Abstract:
    Variable electrical generation (VG) sources such as wind farms are an increasing percentage of total electrical generation in the Bonneville Power Administration (BPA) balancing area and are starting to impact the ability of the regional balancing authority to control the electric grid. Wind farms are not dispatchable and challenge historical...

  • The wave energy resource of the US Pacific Northwest

    Creator:
    Lenee-Bluhm, Pukha
    Abstract:
    The substantial wave energy resource of the US Pacific Northwest (i.e. off the coasts of Washington, Oregon and N. California) is assessed and characterized. Archived spectral records from ten wave measurement buoys, operated and maintained by the National Data Buoy Center and the Coastal Data Information Program, form the basis...
