Abstract for: Modeling of Natural Gas Networks for Consequence Analysis

Modeling infrastructure systems has long served an important role in helping system owners/operators and governments identify systemic risk and apply resources and planning, where necessary, to mitigate said risk and allow for more resilient infrastructure systems. Sandia’s NetFlow Dynamics model (NFD) is a network-based dynamic modeling system designed to capture the performance of regional- to national-scale natural gas pipeline networks in response to disruptive events. Originally developed to model crude and refined petroleum products pipelines, it has recently been applied to natural gas networks to study complex, time-dependent interactions in production, transport, storage, and consumption. NFD can be applied in support of a range of problems and has been validated against previous incidents.
