Topological modelling and simulation of gas networks for multi-energy applications

This paper addresses the generation of a topological model of a gas network to be used in an integrated multi-carrier energy co-simulation framework. The study is based on a set of three real gas networks and emphasis is put on both a unified graph based description and a steady-state simulation carried out via an electrical circuit analogy and classical tools for circuit analysis. An isothermal assumption is also considered and validated. The proposed approach turns out to be a first step toward a simple and viable solution for the efficient co- simulation of a possibly complex energy scenario involving renewables, electrical and gas networks.
