Measurement-Based Operational Reliability Tools PhD student Kai Van Horn with advisers A. Domínguez-García and P. Sauer Real-time operational reliability assessment is a key component of system operators’ strategies for maintaining grid reliability. Such assessment requires tools that can provide system operators with up-to-date information about current operating conditions, e.g., transmission lines at their thermal limits, […]
Optimal PMU Placement for Quickest Line Outage Detection and Identification
Optimal PMU Placement for Quickest Line Outage Detection and Identification PhD student Xichen Jiang with adviser A. Domínguez-García Timely line-outage detection for power system transmission line outages is crucial for maintaining reliability in the power grid. Currently, many of the methods for online power system monitoring rely on a system model that is obtained offline, […]
Quantifying the Impacts on Reliability of Coupling between Power System Cyber and Physical Components
Quantifying the Impacts on Reliability of Coupling between Power System Cyber and Physical Components PhD student Jiangmeng Zhang with adviser A. Domínguez-García The operation of most modern electrical energy systems is dependent on a cyber infrastructure encompassing sensing, communication, and control devices (cyber components); however, there is no systematic method to evaluate the impact of […]
Applying Differential Power Processing to Series-Stacked Processors for Efficiency Improvement in a Multi-Processor Server or System
Applying Differential Power Processing to Series-Stacked Processors for Efficiency Improvement in a Multi-Processor Server or System PhD student Andrew Stillwell with advisers R. Pilawa-Podgurski and P. Sauer As the capabilities of the internet and cloud services grow, so too grows the demand for data centers. These centers are increasingly taking up a larger percentage of […]
An Active-Power Load-Sharing Controller for Frequency Regulation in Inverter-Based Microgrids
An Active-Power Load-Sharing Controller for Frequency Regulation in Inverter-Based Microgrids PhD student Madi Zholbaryssov with adviser A. Dominguez-Garcia We propose a generation control strategy for lossless microgrids with inverter-interfaced generators. In particular, we address the problem of obtaining a desired active-power load sharing while regulating the frequency to some nominal value. The proposed control strategy […]
Distributed Frequency Control of Inertia-Less AC Microgrids
Distributed Frequency Control of Inertia-Less AC Microgrids PhD student Stanton T. Cady with adviser A. Domínguez-García The focus of this work is to develop and simulate […]
LOAD FLEXIBILITY MODELING AND CONTROL
LOAD FLEXIBILITY MODELING AND CONTROL PdD student Justin Hughes with adviser A. Domínguez-García Frequency regulation is becoming increasingly important with deeper penetration of variable generation resources. Flexible loads have been proposed as a low-cost provider of frequency regulation. For example, the flexibility of loads with inherent thermal energy storage resides in their ability to vary […]
Quantifying Photovoltaic Frequency Content and Determining Filtering Potential for Stochastic Solar Resources Using HVAC Drive Control
Quantifying Photovoltaic Frequency Content and Determining Filtering Potential for Stochastic Solar Resources Using HVAC Drive Control Daily 5 kHz rooftop solar data was previously collected for two years from two rooftop solar panels on Everitt Laboratory (see Figure 1). Continued analysis revealed the location and type of recording errors, inconsistencies, and missing data. Figure 2 […]
Modeling of Solar Costs and Sensitivity
Modeling of Solar Costs and Sensitivity MSEE/MBA student Mark Hagge with adviser P. Krein A discounted cash flow model of solar panel installations was built in Excel to provide a direct, readily understood, and open cost analysis of PV systems. It was used to evaluate the current economic state of solar panel adoption across the […]
A Stochastic Approach to Asynchronous Differential Power Processing for True Maximum Power Point Tracking of Photovoltaic Sub-modules
A Stochastic Approach to Asynchronous Differential Power Processing for True Maximum Power Point Tracking of Photovoltaic Sub-modules MSEE student Felix Z. Hsiao with adviser R. Pilawa-Podgurski Modules and sub-modules must be biased at the correct voltages and currents in order to extract the maximum power from photovoltaic (PV) systems. Since these operating points change dynamically […]
