Abstract
This study investigates the joint water–power system resilience of an irrigation district in southeastern Idaho. Irrigation districts face difficulties in the delivery of water to farmers under drought conditions, during equipment failures, or unplanned infrastructure disruptions. The resilience of interconnected water and power systems can be better analyzed and understood through an integrated approach, using a model that connects the dependencies between the two halves of the system. Using a multi-agent system model capturing both water and power system components, as well as their linkages, we capture the interdependencies of these systems and highlight opportunities for improvement when faced with disruptions. Through simulation scenarios, we examine the system resilience using system performance, quantified as the percentage of met demand of the power and water system, when subjected to drought water year, an unforeseen water demand increase, power outage and dam failure. Scenario results indicate that the effects of low flow years are mostly felt in the power system; unexpected increases in water demand marginally impact irrigation system performance; dams and pumps present vulnerabilities of the system, causing substantial unmet demand during disruptions. Noting the interdependencies between the water–power system halves while leveraging an integrated simulation allows for an insightful analysis of the system impacts during disruptions.
Highlights
Power and water infrastructure systems rely on their interdependence to ensure their service requirements, i.e., to meet power and water demand requirements, respectively.Generating units available in power systems should be dispatched appropriately to ensure a reliable delivery, whenever, wherever and of whatever quantity to consumers, which can be of commercial, industrial, and residential types
The model offers a more functional oriented representation of both the power system andthe thepower water we present in this paper offers a more functional oriented representation of both system, with detailed operation and co-management features with contingency composystem and the water system, with detailed operation and co-management features with nents represented
We examine the system resilience, via system performance, of this study is that it focuses on rural area community, relying on community-man measured as explained in Section 2, when subjected to drought year, unforeseen water demand increase, power outage and dam failure
Summary
Power and water infrastructure systems rely on their interdependence to ensure their service requirements, i.e., to meet power and water demand requirements, respectively.Generating units available in power systems should be dispatched appropriately to ensure a reliable delivery, whenever, wherever and of whatever quantity to consumers, which can be of commercial, industrial, and residential types. The same phenomenon is observed in water systems, with water sources designed to supply demands, which can be of nonirrigation (residential, commercial, and industrial, etc.) and irrigation types. The purpose of the project is to supply water water to the land, to build a reliable source of power, and provide opportunities to develop to the land, to build a reliable source of power, and provide opportunities to develop farmland in the area. The dam supplies irrigation water to the Snake River valley in farmland in the area. Dairy, potatoes, beets, beans, grains, and irrigated pasture are important important agricultural uses for the water supplied to the district. In addition to irrigation agricultural uses for the water supplied to the district. Surplus power beyond the Bureau of Reclaof Reclamation (BoR) needs is marketed in the Federal Southern Idaho Power System, mation (BoR) needs is marketed in the Federal Southern Idaho Power System, overseen overseen by the Bonneville Power Administration [31]
