Feedback in Combined Dynamic Gas and Electricity Networks

Welcome to the first intermediate-level coupled networks tutorial. In this new tutorial, your modeling skills and your knowledge of SAInt are pushed to the next level! You start here to demonstrate how to solve exciting combined simulation problems by coupling gas and electric systems, exploring their interaction and dynamics, and assessing spill-over effects and feedback. The ideas presented will describe SAInt’s approach to combined simulation, assist you in creating a coupled system in the GUI, and showcase how to create feedback loops.

The term "combined simulation" is different from "co-simulation". A combined simulation is the joint simulation of strongly coupled and interconnected systems, a single mathematical problem, considering the constraints on each system and the coupling equations, is formulated and solved for every time step. A co-simulation is the joint and coordinated simulation of loosely coupled stand-alone simulations with their suitable solver, already well-established tools, and semantics. See Sergi and Pambour (2022) for more details on SAInt and combined simulations.

If you don’t feel conformable with some of the steps presented in this intermediate series, you have you covered. Check the beginner tutorial series, explore the reference guide of SAInt, or go to the How-to guides.

This series starts by laying down the steps you must follow in SAInt to create a coupled system. The concept and requirements of a "coupled scenario" are then introduced, and combined simulations are carried out by means of multiple examples. The final step covers more advanced material on implementing bidirectional relationships and feedback loops.
