The development of an analytical method used for conducting a power flow analysis on a DC power system containing multiple motor-drive loads is presented. The method is fast, simplistic, easy to implement, and produces ...

An Analytical Study of a Grid Connected Direct Drive Permanent Magnet Generator Wind Turbine: Modeling and Simulation

Bugg, Carl (2018-11-14)

Wind is clean, free and a readily available energy source. Around the world, every day, wind turbines are capturing the wind’s power and converting it to electricity. There is considerable interest in wind power as a ...

Control, Modeling, and Analysis of Inverter-Based Resources

Baker, William (2021-11-23)

The increased penetration level of Inverter-Based Resources (IBR) presents new challenges to the planning and operation of electric grids traditionally designed, protected, and operated based on the inherent characteristics ...

Dynamic Model Development and System Study of Ternary Pumped Storage Hydropower

Dong, Zerui (2019-04-18)

The conventional role of pumped storage hydropower (PSH) is energy storage: it generates power when it operates as a hydro turbine, and store energy from the electric grid when pumping water from the lower reservoir to the ...

Evaluation of Low Frequency Communication Techniques for Load Phase Identification

Geiger, Daniel, II (2011-11-14)

This is a discussion on the process of implementing a system for power line communication (PLC). A PLC system is desired as it will allow for phase identification of the load and the transmission of data from the load ...

Identification of Individual Contributions to Total Flicker Levels in Electric Power Systems

Gosnell, Ryan (2010-04-02)

Total flicker levels in an electric power system can be contributed to from multiple sources of flicker. Methodologies for allocating portions of this total flicker level to the responsible loads are studied. The representation ...

A Method to Discriminate Between Flicker Sources

Geiger, Daniel, II (2015-07-29)

This work is a discussion on discriminating between multiple flicker producing sources that are connected electrically close together in the power system. IEC 61000-4-15 provides a thorough description on how to build a ...

A Methodology for Estimating the Parameters of Steam Turbine Generator Shaft Systems for Subsynchronous Resonance Studies

Sambarapu, Krishna (2012-07-31)

The increase of coal and nuclear power steam turbines over the past few decades combined with transmission line series capacitors creates a potential drawback known as subsynchronous resonance (SSR) by increasing the risk ...

Modeling a Fuel Cell System for Residential Dwellings

Trueblood, Christopher (2006-05-15)

Fuel cells produce electricity by combining hydrogen and oxygen to form water. Fuel cells have unique electrical characteristics and performances that warrant examination and discussion. From the hydrogen source to the ...

Online In-Situ Estimation of Network Parameters Under Intermittent Excitation Conditions

Taylor, Jason (2008-08-15)

Online in-situ estimation of network parameters is potential tool to evaluate electrical network and conductor health. The integration of the physics-based models with stochastic models can provide important diagnostic ...

Optimization of High Power Gallium Nitride Based Point of Load Converters for Data Center Power Supply Chains

Jenkins, Luke L. (2015-04-30)

Wide-bandgap semiconductors are enabling higher efficiency, greater power density, smaller size, and higher switching frequency than traditional Si semiconductors. This work shows the development of an over 96% efficient ...

Power Management of a Grid Forming Enabled Hybrid Energy System

Ezeodili, Echezona (2021-12-03)

Hybrid power generation systems that combine different renewable energy sources and energy storage systems offer an environmentally friendly alternative to conventional power generators for stand-alone applications. However, ...

Power Quality Standard Comparison between China, IEEE, and IEC

Zheng, Tianxu (2018-11-15)

This thesis compares power quality standards and measurement methods of the U.S. and China. These standards specify the power quality parameters (harmonics, flicker, unbalance,etc.), that are dedicated to ensure the ...

Predicting Generator Coupling Using Power System Impedance Matrices

Sayler, Kent (2006-05-15)

The combination of power flows on multiple lines constitutes a flowgate. Transmission flowgates are one tool being used to deal with wide-area stability issues because experience with dynamic simulation suggests that ...

Reactive Power Compensatioin Device Design with Utilization of an Integrated Circuit Controller
