Abstract：

The phrase water-energy nexus is commonly used to describe the inherent and critical interdependencies between the electric power system and the water delivery system (WDS). In this work, an analytical framework capturing the interactions between these two critical infrastructures is examined and a mathematical model to describe the associated dynamics is developed. Based on the time-scale of the associated dynamics, the electric network behavior is represented using time-series power flows following unit commitment and optimal power flow solutions. The WDS is represented using continuity equations at the delivery junction nodes and energy equations around the delivery loops and from tanks and reservoirs to the network. An integrated simulation engine of the interdependent infrastructure systems is formulated to conduct long-term simulations. Test cases have been conducted to show the impact of mega droughts and electric supply disruptions on the two interdependent systems.
