In the near future, global water, energy, and food security will face significant challenges from climate change, as well as the global population growth. In light of the depletion of certain natural resources, the assurance of the security of a specific sector, such as energy, may adversely affect the security of other sectors, such as water and food supply, and consequently, environmental sustainability. As a result, conventional solutions to increase demand will no longer be an option in that they try to address the problems observed in different systems independently instead of understanding the interdependencies and interactions among them. Advances in water, energy, and food security need to be addressed within a revised framework that explicitly incorporates the key couplings among the water, energy, and food sectors. The security of the water, energy, and food production and distribution, under climate change and demand growth, may be attained by the effective leveraging of new technologies. Such an opportunity is accompanied by a set of diverse problems in engineering, economics and other social sciences, whose formulation must be first stated and the appropriate analytic tools for their solutions must be developed.
This talk focuses on the water and energy networked infrastructures. We discuss the utilization of distributed energy resources (DERs) in microgrids to provide energy and ancillary services to the grid in the day-ahead and the real-time energy and regulation markets. We characterize the interdependencies and interactions between water and energy for water supply. In addition, we present an architecture for harvesting renewable energy in the water infrastructural system.
