Real Time Modeling of the University of Illinois Urbana-Champaign Power Grid
MS student Ethan WIlliams with Advisor A. 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, allowing for testing and validation of control schemes under multiple disturbance scenarios. Leveraging the software’s ability to allow for real-time simulation, this project aims to replicate and build upon a model developed in GE PSLF (transmission planning software) of the University of Illinois Urbana-Champaign power system and its associated power monitoring and control system. The goal is to expand upon tested operating scenarios in the original model and potentially develop recommendations for improvements to the control scheme. Preliminary progress has been made in building standardized models for the various components within the power system, which were utilized in the original GE PSLF model. Models of the “GGOV1” governor, “AC5A” exciter, and “GENQEC” synchronous machine, as shown in Figure 29, have been created and are incorporated to represent steam and gas turbines in the campus power grid. Currently, this project is inactive, but the developed models will accelerate the process of building the full model for the campus grid in the future.
