PhD student Samith Sirimanna with Advisor K. Haran Magnet eddy currents are generated from two main sources in permanent magnet synchronous machines: spatial and time harmonics. Discrete winding distribution in the stator generates spatial harmonics that are asynchronous with the main rotor field while inverter switching creates time harmonics in the current waveform. Generally, resistance-limited […]
Progress Report – Illinois Solar Decathlon’s RENU-House
We are thrilled to report that the Illinois Solar Decathlon construction of the RENU House is mostly complete. A public exhibition showing our progress was held on April 15 and 16. We would like to express our gratitude to CEME for their support, which has enabled us to turn this project into a reality. Illinois […]
Illinois Formula Electric
“Illini Formula Electric (IFE) is the University of Illinois Urbana-Champaign’s electric Formula SAE team. We design, build, and race electric formula cars. Every summer, our vehicle competes at the Formula SAE competition organized by SAE International. The team competes in a variety of static and dynamic events such as design, presentation, cost, acceleration, skidpad, autocross, […]
Reduced-Order Modeling of Inverter and Synchronous Generator based Power Networks
MS student Ethan Wllliams with Advisor A. D. Domínguez-García. Stability has become an increasing concern with the growing penetration of renewable energy sources into power systems because of the decrease in system inertia as synchronous generation is replaced by inverter-based generation and other aspects. Specifically, given the wide variety of control strategies implemented for inverter-based […]
Real Time Modeling of the University of Illinois Urbana-Champaign Power Grid
MS student Ethan Wllliams with Advisor A. D. Domínguez-García. Typhoon HIL, a controller-hardware-in-the-loop simulation platform, can accurately capture power-system dynamic phenomena occurring at super-fast time scales (microseconds), much faster than conventional simulators such as MATLAB/Simulink. Further, Typhoon HIL provides a flexible development environment where power systems and associated components can be modeled and easily configured, […]
A Resilient Distributed Platform for Microgrid Control Environmental Security Technology Certification Program
PhD student Eric Silk with Advisor A. D. Domínguez-García. The goal of this project is to develop and demonstrate a software framework for the control of microgrids by using distributed algorithms. My contributions thus far have largely involved applying modern software practices to convert existing code to a platform-agnostic implementation, i.e., one that run on […]
A Quasi-Newton Algorithm for Solving the Power-Flow Problem in Inverter-Based Power Systems.
PhD student Temitope Amuda with Advisor A. D. Domínguez-García. Commercial power-flow solvers compute the solution to the single slack-based power-flow problem using conventional approaches such as the Newton-Raphson or the Gauss-Seidel methods. In the conventional power-flow formulation, a single bus with a fixed normalized voltage and angle is dedicated to carrying all the slack in […]
Primary and Secondary Control of Dispatchable Virtual Oscillator-Controlled Grid-Forming Inverters
PhD Student T.G. Roberts with Advisor A. Domínguez-García Grid Forming Inverters (GFMs) are a promising technology for replacing synchronous generators to sustain system voltage and frequency in microgrids with low inertia. In the U.S. bulk power grid, inertia from rotating generators helps resist sudden changes or fluctuations in frequency. Currently, grid following inverters (GFLs) do […]
Extracting Power from ECEB Research Solar Panels Using Distributed Controllers
Intern Zhan Su and PhD Student Matthew Qi with Advisor A. Banerjee Illinois’s Electrical and Computer Engineering Building has sixty 400W solar panels dedicated solely for research. This project, funded by the Grainger CEME, aims to create an efficient, reliable, and safe hardware framework to extract power from these solar panels and feed it to […]
200-kW Integrated Generator-Rectifier Prototype for Wind Energy Systems
Post-doc Debranjan Mukherjee with Advisor Dr. Arijit Banerjee Offshore wind energy conversion systems are getting increased attention due to high and steady wind potential and minimum environmental effects. Our group has proposed an integrated generator-rectifier architecture. The generator considered has multiple three-phase ac ports. Most of these ports are connected to diode-bridge rectifiers while one […]
