The concept of supply chain resilience continues to attract both industry and research
experts in the field of energy. These stakeholders continue to tackle disruptions to supply …

The development of mathematical simulation and optimization models and algorithms for
solving gas transport problems is an active field of research. In order to test and compare …

We consider optimal control problems for the flow of gas or fresh water in pipe networks as
well as drainage or sewer systems in open canals. The equations of motion are taken to be …

We develop a complementarity-constrained nonlinear optimization model for the time-
dependent control of district heating networks. The main physical aspects of water and heat …

We study the transient optimization of gas transport networks including both discrete controls
due to switching of controllable elements and nonlinear fluid dynamics described by the …

In entry-exit gas markets as they are currently implemented in Europe, network constraints
do not affect market interaction beyond the technical capacities determined by the TSO that …

Common energy system models that integrate hydrogen transport in pipelines typically
simplify fluid flow models and reduce the network size in order to achieve solutions quickly …

The simulation of gas transportation networks becomes increasingly more important as its
use-cases broaden to more complex applications. Classically, the purpose of the gas …

We propose a method for solving mixed-integer nonlinear programmes (MINLPs) to global
optimality by discretization of occurring nonlinearities. The main idea is based on using …

Detailed modeling of gas transport problems leads to nonlinear and nonconvex mixed-
integer optimization or feasibility models (MINLPs) because both the incorporation of …
