Day-Ahead Economic Dispatch of Coupled Desalinated Water and Power Grids Incorporating Pure Electric Vehicles

Water and electricity are closely interdependent essential sources in human life that affect socio-economic growth and prosperity. In other words, electricity is a fundamental resource to power a seawater desalination process, while fresh water is used for cooling this power plant. Therefore, mutual vulnerability of water treatment and power generation systems is growing because of increased potable water and electricity demands especially during extremely-hot summer days. Hence, this papers presents a novel framework for day-ahead economic dispatch of coupled potable water and electricity production facilities incorporating aggregated plug-in electric vehicles as energy storage technologies. A mixed integer non-linear programming problem is solved to minimize total water treatment cost of water only units and co-producers and total fuel cost of power only plants and co-generators while considering all operational constraints of co-producers, power and desalination plants
