Water distribution systems (WDSs) are energy intensive infrastructures that rely on water storage plants and variable speed pumps for delivering to the end consumers. The WDSs represent suitable candidates enhancing flexibility of power operation through optimizing flexible components (pumps tanks). However, have traditionally been treated as infrastructure uncoupled from system operators' efforts minimize cost supplying electricity demand. In this paper, we propose a model integrating in...

Handling the variability and uncertainty associated with integrating large capacities of renewable energy sources (RES) into power grid is a challenge that increasingly influencing systems operation. At same time, growing need for desalinated water in arid areas increases importance suitable sustainable operation desalination plants. However, as system operators have traditionally operated their isolation, there lack understanding interdependence interactions between these two systems. This...

Abstract Around 60% of households in Texas currently rely on electricity for space heating. As decarbonization efforts increase, non‐electrified could adopt electric heat pumps, significantly increasing peak (highest) demand winter. Simultaneously, anthropogenic climate change is expected to increase temperatures, the potential summer waves, and associated cooling. Uncertainty regarding timing magnitude these concurrent changes raises questions about how they will jointly affect seasonality...
