LF Energy Summit Europe 2026

Dynawo is an Open-Source, production-level dynamic simulator developed by RTE, now in use for operations planning processes. It is also the reference tool for validating the compliance of new projects to grid code requirements in France. Dynawo comes with an extensive library of RMS models written in Modelica, including a complete suite of generic models (WECC, IEC) for inverter-based resources.

This Tutorial will benefit anyone who is interested in using and/or extending Dynawo's *model library* but is finding that Dynawo (the *simulator*) has a steep learning curve. In particular, we will be presenting new tools designed for facilitating the uptake of Dynawo's models, demonstrating a few use-cases:
* Usage within pure Modelica: solving the initialization problem
* Usage of Dynawo via PyPowSyBl: construction, manipulation, and visualization of (large) study cases
* Parameter-sweep studies
* Small-stability analysis

The tools take the form of Python and Julia Notebooks, designed to be flexible and easy to change by end-users. The session will also emphasize *understanding* these tools to encourage the customization and promote new creative solutions.
