Hazards SEES: GIC Hazard Prediction: From the Solar Wind to Power System Impacts

 Led by Dr. Thomas Overbye of the University of Illinois at Urbana-Champaign, this project is intended to improve the scientific understanding of the processes governing the impacts on our power distribution system of severe solar storms. The team is studying the relationship between solar wind drivers and magnetic field perturbations on the ground, developing improved models of induced electric fields, and enhancing prediction capabilities for GIC hazards. The team is developing algorithms that both advance the science of induced electric fields and operate as a predictive tool of GIC hazards in the bulk power system, including transformer heating and damage and loss of voltage stability. Impact models are being developed, enhanced, and validated to provide better prediction of the effects of GMDs on power systems for both real-time response and longer-term resilience.
