Optimization-based Re-routing and Reserve Activation Dispatch Calculations in Natural Gas Network Models

: Computational models corresponding to supply security in natural gas networks aim to describe flows and consumption values in the case of component failures or un-forseen pipeline shutdowns. The role of natural gas reservoirs in this process has only been marginally analyzed in such models, and typically only on the level of countries, not on the level of international networks. In this paper, a computational framework is proposed to determine the resulting flows of a natural gas network following a line failure, considering the potential re-routing of available sources and reservoir activations as well. The proposed dispatch-type model is capable of explicitly considering real, and publicly available flow and reservoir data to determine the resulting flows in the case of component outages, considering the re-routing process as well.
