ECE – 590 I POWER & ENERGY SYSTEMS SEMINAR Monday, March 14, 2016, 4:00 – 5:00 p.m., Room 2017, ECEB Modelling the Impact of Water Constraints on Electric Power Generation Desiree Phillips Department of Electrical and Computer Engineering University of Illinois at Urbana-Champaign Abstract As part of an interdisciplinary project with the Department of Civil and Environmental Engineering at Illinois, we are involved in a project to examine the relationship between the electric power grid and other United States critical infrastructures. We report in this presentation on the scope of the project. We start with the water-energy nexus and deploy extended models of the electric grid to quantify the interdependent nature of water and energy supply infrastructures from the optimal-power-flow (OPF) perspective. The extended models that we will develop will be able to analyze the response of grid operations to water constraints, considering both limited water availability and degraded water quality. Compensation for High Impedance Line Drop In Power Network Equivalents Wonhyeok Jang Department of Electrical and Computer Engineering University of Illinois at Urbana-Champaign Abstract The construction of equivalent power system models entail creation of the equivalent lines are and some of them may have high impedance. Typically, such high-impedance lines are dropped for simplicity from the models as they have very low power flows. Such dropped lines impact the accuracy of the equivalent system representation of the original network. This presentation describes the needed compensation for these line drops so that the flows on the retained lines in the equivalent system are close as to those in the original network.
