Node Importance Analysis Of A Gas Transmission Network With Evaluation Of A New Infrastructure By Progasnet

We present a probabilistic approach for identification and ranking of important gas network components from the security of supply point of view. We perform a probabilistic risk analysis of a regional European gas transmission network under selected attack scenarios. Moreover, in order to evaluate security of supply consequences of a new gas infrastructure project, this analysis is performed twice: before and after the infrastructure project. The results of 1 million of Monte-Carlo simulations under the attack scenarios clearly indicate various gas supply consequences. Thus, the obtained list of most critical components includes suitable candidates for the protection of infrastructure.
