Modeling and Simulation of Sector-Coupled Energy Networks: A Gas-Power Benchmark

Efficient simulation of coupled gas and power networks under uncertain demands

“…Several different conditions exist, see [33,44,45]. Yet, for the purpose of real-world gas pipelines, [24] seems to indicate that coupling via equality of pressure is sufficient for the expectable accuracy of the whole modelling approach. Therefore, consider a node n ∈ N G with K adjacent arcs.…”

“…Gas power plants are also modelled as arcs in the graph connecting a power node and a gas node. They transform gas into power at a linear rate and also power into gas at a (different) linear rate as was done in [24]. At the switching point, we smooth the resulting kink with a polynomial.…”

“…This has no physical counterpart and is done purely for numerical reasons. Note that due to technical reasons, our polynomial maps gas flow to power instead of the other way around as was chosen in [24]. For the power output of the gas power plant, there holds…”
