Dynawo is an hybrid C++/Modelica open source suite of simulation tools for power systems. This integration module allows to use DynaFlow for power flow simulations and Dynawo for time domain simulations.
To use DynaFlow as your power flow engine, add the com.powsybl:powsybl-dynaflow module to your dependencies.
Network network = Network.read("/path/to/the/casefile.xiidm");
LoadFlowParameters parameters = LoadFlowParameters.load();
LoadFlow.find("DynaFlow").run(network, parameters);To learn more about the usage of DynaFlow, read the dedicated page on our website.
To use Dynawo as your time domain engine, add the com.powsybl:powsybl-dynawo and com.powsybl:powsybl-dynawo-dsl modules to your dependencies.
To run a dynamic simulation, you need:
- a case file
- a
DynamicModelsSupplierto associate dynamic models to the equipment of the network - an
EventModelsSupplerto configure events simulated during the simulation (optional) - an
OutputVariablesSupplierto follow the evolution of dynamic variables during the simulation (optional) - a set of parameters to configure the simulation (optional)
Thanks to powsybl-dynawo-dsl, the inputs can be easily configured using Groovy scripts.
The simulation parameters can be configured either in the config.yml file or using a Json file.
Network network = Network.read("/path/to/the/casefile.xiidm");
// Load the dynamic models mapping
DynamicModelsSupplier dynamicModelsSupplier = new GroovyDynamicModelsSupplier(
Paths.get("/path/to/dynamicModelsMapping.groovy"),
GroovyExtension.find(DynamicModelGroovyExtension.class, DynawoSimulationProvider.NAME));
// Load the events
EventModelsSupplier eventModelsSupplier = new GroovyEventModelsSupplier(
Paths.get("/path/to/event.groovy"),
GroovyExtension.find(EventModelGroovyExtension.class, DynawoSimulationProvider.NAME));
// Configure the output variables
OutputVariablesSupplier outputVariablesSupplier = new GroovyOutputVariablesSupplier(
Paths.get("/path/to/outputVariables.groovy"),
GroovyExtension.find(OutputVariableGroovyExtension.class, DynawoSimulationProvider.NAME));
// Load the parameters
DynamicSimulationParameters parameters = DynamicSimulationParameters.load();
// Run the simulation and display the results
DynamicSimulationResult result = DynamicSimulation.run(network, dynamicModelsSupplier, eventModelsSupplier, outputVariablesSupplier, parameters);
System.out.println(result.getStatus());
System.out.println("Timeline:");
result.getTimeLine().forEach(tl -> System.out.printf("[%.8f] %s (on %s)%n", tl.time(), tl.message(), tl.modelName()));To learn more about the usage of Dynawo, read the dedicated page on our website.
This is an example of a dynamic models mapping file:
import com.powsybl.iidm.network.Line
import com.powsybl.iidm.network.Load
import com.powsybl.iidm.network.Generator
for (Load load : network.loads) {
LoadAlphaBeta {
staticId load.id
parameterSetId "LAB"
}
}
for (Generator gen : network.generators) {
GeneratorSynchronousThreeWindingsProportionalRegulations {
staticId gen.id
parameterSetId "GSTWPR"
}
}
for (Line line : network.lines) {
OverloadManagementSystem {
dynamicModelId "BBM_" + line.id
parameterSetId "CLA"
controlledBranch line.id
iMeasurement line.id
iMeasurementSide TwoSides.TWO
}
}Note that this mapping file refers to parameter set ids which should be found in the Dynawo parameters file. For the above example, the corresponding parameter file could be:

The documentation sources for PowSybl Dynawo features are in the docs folder.
Please keep them up to date with your developments.
They are published on https://powsybl.readthedocs.io and pull requests are built and previewed automatically via github CI.
When modifying the website content, you can easily preview the result by building the docs locally. To do so, run the following commands:
pip install -r docs/requirements.txt
sphinx-build -a docs ./build-docsThen open build-docs/index.html in your browser.
If you want to add links to another documentation, add the corresponding repository to the conf.py file.
In order to automatically get the version specified in the pom.xml, please use the same naming as the version: if you define the
Groovy version with <groovy.version>, then use groovy as key. The specified URL should start with https:// and end with latest/ (the final / is mandatory).
For example, to add a link to the documentation of Sphinx, you need to add the following lines:
# This parameter might already be present, just add the new value
intersphinx_mapping = {
"sphinx": ("https://www.sphinx-doc.org/en/master/", None),
}Then in your documentation file, you can add links to Sphinx documentation. If you want to link to a whole page, use one of the following example:
- {doc}`sphinx:usage/extensions/intersphinx`
- {doc}`Intersphinx <sphinx:usage/extensions/intersphinx>`
- [Intersphinx](inv:sphinx:std:doc#usage/extensions/intersphinx).If you want to link a specific part of a page, use one of those examples:
- [Intersphinx roles](inv:#ref-role).
- [Intersphinx roles](inv:sphinx#ref-role).
- [Intersphinx roles](inv:sphinx:std:label:#ref-role).
- [Intersphinx roles](inv:sphinx:*:*:#ref-role).Note 1: for the last examples to work, there need to be a corresponding reference in the external documentation.
For those examples, (ref-role)= has been added right before the corresponding title
in the Cross-referencing syntax page. Another way to make it work is to use the autosectionlabel module in Sphinx to
automatically generate anchors for each title.
Note 2: if the build fails, try with the -E option to clear the cache:
sphinx-build -a -E docs ./build-docs
