Seismic Reliability Evaluation of Interdependent Water and Power Supply Networks
Seismic reliability assessments of water and power supply networks are typically conducted under the assumption of system independence. This article introduces a novel framework for evaluating the seismic reliability of interdependent water and power supply networks, grounded in a comprehensive analysis of their interdependence mechanisms. The proposed framework integrates network flow theory and the Monte Carlo simulation method, leveraging network flow theory to determine the functional status of various system nodes and employing Monte Carlo simulations to account for random factors such as earthquake intensity. The practicality of the framework is validated through a case study in Shangcheng District. The numerical results reveal that: (1) the proposed method effectively evaluates the seismic reliability of interdependent water and power supply networks, and (2) the interdependent mechanisms and network topology significantly impact the seismic reliability of these networks.
