Resilience of Cyber-Enabled Electrical Energy and Water Distribution Systems Considering Infrastructural Robustness Under Conditions of Limited Water and/or Energy Availability

New metrics and a new methodology for determining system infrastructural-operational resilience are presented for the optimal real-time operation of two critical interdependent infrastructure systems-the water distribution systems (WDS) and the electric power system (EPS) under critical conditions of limited water and/or limited electrical energy resulting from extreme drought or electric grid failure, respectively. Operational resilience (OR) and infrastructural resilience are defined. The integrated resilience computation method is presented and utilizes results from a combined optimization-simulation framework, which involves capturing the interactions and associated dynamics between the EPS and WDS. A realistic example of the WDS and EPS is used to demonstrate the application of the resilience concepts to assess the interdependent systems' performance.
