Simulation and capacity calculation in real German and European interconnected gas transport systems

Více o knize

The natural gas supply chain, from extraction to end-users, forms an intricate network operated by various companies across Europe. The liberalization of energy markets mandates that gas network operators disclose flow capacities at entry and exit points. This transparency, combined with accessible data on gas transportation infrastructures, enables comprehensive hydraulic simulations of gas flows throughout Germany and Europe. Such models are crucial for understanding the logistics and integrity of the natural gas supply system, allowing for assessments of overall gas flow, infrastructure details, and emergency analyses on national and European scales. This thesis outlines the workflow and methodologies for modeling large-scale gas grids, focusing on the German H-gas system. The developed model simulates major gas transmission systems in Germany, accounting for storage facilities. The modeling process encompasses three key aspects: network topology creation, simulation scenario definition, and capacity calculation methodologies. The author details the integration of databases and simplification approaches used in the modeling. By examining German gas consumption trends, various scenarios are simulated to analyze technical potentials at entry/exit points and the nationwide grid. The thesis also presents case studies evaluating new infrastructures and technologies related to Germany's energy transformation, highlighting bottlen
