Abstract

In this paper, a new vulnerability metric for urban natural gas network under cascading failures are proposed, which is based on hydraulic analysis method. Simulation result of a simplified network shows that pressure-driven hydraulic method is more realistic than demand-driven hydraulic method because user’s demand is not fully satisfied under a cascading failure situation. Then the vulnerability analysis procedure is applied to a real-world natural gas network and vulnerability maps under different source assumptions are acquired. The result shows that the spatial distribution of network vulnerability depends heavily on the location of natural gas sources.
