Next TSC meeting


TILLOY Anne
 

Hi everybody,

Our next TSC meeting will be on June 24th.

 

For this public meeting, it would be great if we follow these items:

 

Release of powsybl-core (4.3.0-alpha-1) since May 25th, please refer to the release notes to know what the release contains: Release v4.3.0-alpha-1 · powsybl/powsybl-core (github.com)

 

This intermediate release contains the new security analysis API, including the new feature that monitors the buses and branches results (voltage, angle, active and reactive powers) for pre-contingency state and for post-contingency states. We also support contingency on three windings transformers with this new version, and new limit violation types. OpenLoadFlow has been released too.

 

To be compliant with the European Merging Function, we can now maintain the power factor constant when loads are scaled. A tutorial is in progress to show how to implement the EMF with Powsybl.

 

And as usual, some bus fixes and other quality evolutions.

 

Next release of powsybl-core (4.3.0) expected on July 7th, please refer to the draft release notes to know what the release will contain: Release v4.3.0 (expected date: 2021-07-07) · powsybl/powsybl-core (github.com)

 

New extension to model remote reactive power control for generators (breaking change) ;

A first version of the CGMES importer from a unique EQ file : it is a beta feature mainly used just after SCADA system ;

The possibility to export flows at switches in SV file ;

Still WIP:

- The new sensitivity API ;

- PSSE updated export ;

- Extensions for measurements compliant ;

- Support of CGMES 3.0 ;

- UCTE: use double instead of float. The extension MergedXNode will change too.

 

Roadmap

Roadmap update by annetill · Pull Request #24 · powsybl/.github

Please try to update the PR every month. Having a clear, detailed and updated roadmap is key for external contributions.

 

Technical discussion

Sylvain, Florian and Mathilde are working on a schematic vision of the network to provide SVGs. The SVGs could be integrated in an interface such GridStudy (gridsuite.org) or created from a python script by pypowsybl users (PyPowSyBl’s user documentation — pypowsybl documentation). They imagine that there is a JavaScript component that can be shared between these two applications. Sylvain is going to share some slides before our meeting.

 

Thanks for joining the TSC. Remember that meetings are scheduled here:
