Benefit-Cost Optimization of Resilient Lifeline Networks
Publication: Lifelines 2022
ABSTRACT
Critical infrastructure or lifelines are an essential requirement for society, but measuring, configuring, and designing a lifeline to achieve resilience is a complex and challenging task. We examine urban water and electric power distribution resilient grid concepts using an idealized region typical of a mid-sized US city, stressed by earthquakes of increasing intensity. The damaged water network is hydraulically analyzed for demands due to leaks, breaks, and post-earthquake fires in a pressure driven analysis (PDA). Electric networks are similarly examined considering seismic retrofitting of electric substations. We find: (1) resilient water grids have a benefit-cost ratio (BCR) of about 6:1 to 8:1 for high seismicity regions, such as Los Angeles and San Francisco, with lower values for Seattle and Portland; (2) a major benefit of a resilient water grid is improved supply of firefighting water; (3) resilient power grids have a BCR exceeding 8 for the high seismicity regions; and (4) resilient grids will significantly reduce time to restore water and electric power supply.
