Modelling the Impact of Water Constraints on Electric
Power Generation

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

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.
