Adaptive Single- and Multilevel Stochastic Collocation Methods for Uncertain Gas Transport in Large-Scale Networks
Jens Lang, Pia Domschke, Elisa Strauch
In this paper, we are concerned with the quantification of uncertainties that arise from intra-day oscillations in the demand for natural gas transported through large-scale networ…

Fast and Reliable Transient Simulation and Continuous Optimization of Large-Scale Gas Networks
Pia Domschke, Oliver Kolb, Jens Lang
We are concerned with the simulation and optimization of large-scale gas pipeline systems in an error-controlled environment. The gas flow dynamics is locally approximated by suffi…

Entropy-Preserving Coupling of Hierarchical Gas Models
Pascal Mindt, Jens Lang, Pia Domschke
This paper is concerned with coupling conditions at junctions for transport models which differ in their fidelity to describe transient flow in gas pipelines. It also includes the…
