Contingencies and Hydrogen Blending in Transmission Systems

Welcome to the first intermediate tutorial gas networks tutorial. In this new series of tutorials, you build on the expertise acquired with the beginner tutorials to further consolidate and extend your knowledge in using SAInt to solve exciting problems and challenges in fluid modeling. The ideas presented here will improve the user proficiency in creating a model in the SAInt GUI, increasing accuracy by incorporating quality and temperature, and learning new functionalities (like scripting in IronPython).

If you don’t feel conformable with some of the steps presented in the intermediate series, you have you covered. Check the beginner tutorial series, and explore the reference guide of SAInt, or go to the How-to guides. But if you don’t find what you are looking for, don’t hesitate to contact SAInt support at support@encoord.com!

This series starts by studying a dynamic scenario to investigate the impact of a contingency on the main supply entry to a gas network and the assessment of possible changes in how an electrolyzer injects hydrogen into the system. The model is developed by explicitly describing the gas quality and temperature. The first step is for the user to create a network based on a schematic system description. After the geometry and the topology are fixed, you focus on adding gas quality details and defining the thermal conditions of the system. In the third step, it is time to design the scenario and to set up the constraints describing a contingency to the supply entry point and the changes in how the electrolyzer works. The final step in this simple workflow is to visualize the results, use sessions to study variants of the base scenario, and use the scripting capabilities of the SAInt GUI.
