  • 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...

  • Rapid Grid State Estimation using Singular Value Decomposition

    Creator:
    Kulkarni, Janhavi
    Abstract:
    Synchrophasor technology has gained great momentum with the widely adopted concept of smart grids in power systems at transmission and generation level. This has led to an improved state estimation of a power system with the advent of Phasor Measurement Units (PMU). PMUs contribute in providing real-time information about the...

  • Electromagnetic analysis of energy system devices

    Creator:
    Li, Yan
    Abstract:
    Many new applications of energy system devices have been developed to save energy, improve the controllability and stability of industrial processes, and reduce the weight, volume and cost of consumer devices. Due to the novelty of these devices, traditional empirical methods and lumped-parameter circuit theory methods are not sufficient for...

  • 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...

  • Optimal load shedding and generation rescheduling for overload suppression in large power systems

    Creator:
    Moon, Young-Hyun
    Abstract:
    Ever-increasing size, complexity and operation costs in modern power systems have stimulated the intensive study of an optimal Load Shedding and Generator Rescheduling (LSGR) strategy in the sense of a secure and economic system operation. The conventional approach to LSGR has been based on the application of LP (Linear Programming)...

  • Evaluation of dynamically controlled resistive braking for the Pacific Northwest power system

    Creator:
    Raschio, Peter J.
    Abstract:
    Today's power systems are undergoing dynamic changes in their operation. The high cost of capital improvements that include new generation and transmission projects has prompted power system planners to look for other alternatives in dealing with increased loads and overall system growth. A dynamic braking resistor is a device that...

  • 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...

  • 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...

  • Industrial power system faults

    Creator:
    Badr, Ahmad Mohamad Amin
    Abstract:
    The purpose of this thesis is to represent and calculate unsymmetrical secondary faults on a grounded wye-to-delta transformer bank. This thesis is specifically concerned with the secondary connections often encountered in industrial installations. Faults on these systems have not been adequately investigated. Three types of faults are considered, namely: 1....

  • Applications of mathematical programming techniques in optimal power flow problems

    Creator:
    Li, Ruqi
    Abstract:
    In the past two decades, a great amount of attention has been paid to investigating the economic and safe operation of power systems using modern mathematical techniques. The classic economic dispatch problem, now often called the Optimal Power Flow problem, has been formulated as a mathematical optimization problem and has...
