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…
Modeling and simulation of sector-coupled networks: A gas-power benchmark
Eike Fokken, Tillmann Mühlpfordt, Timm Faulwasser +2
In this contribution, we aim at presenting a gas-to-power benchmark problem that can be used for the simulation of electricity and gas networks in a time-dependent environment. Bas…
Chance-constrained optimal inflow control in hyperbolic supply systems with uncertain demand
Simone Göttlich, Oliver Kolb, Kerstin Lux
In this paper, we address the task of setting up an optimal production plan taking into account an uncertain demand. The energy system is represented by a system of hyperbolic part…
Weighted Essentially Non-Oscillatory stochastic Galerkin approximation for hyperbolic conservation laws
Louisa Schlachter, Florian Schneider, Oliver Kolb
In this paper we extensively study the stochastic Galerkin scheme for uncertain systems of conservation laws, which appears to produce oscillations already for a simple example of…
Optimal control of compressor stations in a coupled gas-to-power network
Eike Fokken, Simone Göttlich, Oliver Kolb
We introduce a tool for simulation and optimization of gas pipeline networks coupled to power grids by gas-to-power plants. The model under consideration consists of the isentropic…
