Quantitative supply security related significance measures for gas reservoires

Computational models corresponding to supply security in natural gas networks aim to describe flows and consumption values in the case of component failures or unforseen pipeline shutdowns. The role of natural gas reservoires in this process has only been marginally analyzed in such models, and typically only on the level of countries. In this paper we define a computational framework, which is capable of interpreting real flow and reservoir data to assign a quantitative supply security related measure to reservoires, depending on how much the given reservoir is critical in the process of restoring consumption outages in the network.
