Resilience assessment methodology of natural gas network system under random leakage

Qiangqiang Jiang et al.

Summary: Natural gas accounts for more than 20% of global primary energy demand. A new methodology combining Monte Carlo simulation and hydraulic analysis of an unsteady flow is developed to evaluate the resilience of the natural gas network system (NGNS) under random leakage conditions. The proposed methodology considers the compressibility of natural gas and resolves system uncertainty in damage and recovery states through batch simulation.
