Next TSC meeting


TILLOY Anne
 

Hi everybody,

Our next TSC meeting will be on January the 13th.

 

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

 

Release of powsybl-core (4.6.0) available since one week that includes:

- The delayed validation has not been released and is still under review ;

- The sensitivity analysis API has not been released, but the PR is ready to be merged ; as it is a major refactoring, we have decided to wait for the applications to be ready ;

- Note that from now, by default in the LoadFlowParameters, the slack is read in the network by default ;

- Graph: we have fixed a stack over flow error met in our tests of large network (Matpower Synthetic USA) ;

- CGMES conversion : work to support CIM configuration from SCADA system ;

- Groovy : improve the IIDM extension adder ;

- Matpower : fixes ;

 

Please refer to the release notes to know what the release contains in more details.

 

Release of powsybl-core (4.7.0) expected on February 23rd, please refer to the release notes to know what the release contains: Release v4.7.0 (expected: 2022-02-23) · powsybl/powsybl-core (github.com)

 

And the expected features for the next release:

- The new sensitivity analysis API, but we still have issues to synchronize our legacy. The impact on FARAO community is okay.

- Matpower: support of phase tap changers ;

- Some functional logs on CIM-CGMES importer and exporter ;

- CGMES: a TP export ;

- Measurements and DiscreteMeasurements: allows to ensure ID unicity ;

- A delayed validation of IIDM for post SCADA use cases.

 

Other repositories:

- OLF: we have merged the shunt voltage control. We are working on performance improvement of security analysis. It will be included.

- Mathieu: IIDM C++, support of IIDM v1.5

- Sylvain or Geoffroy: new features of pypowsybl.

- Florian: SLD and network-area-diagram.

- Dynawo: Luma

- powsybl-network-hypothesis: utility functions to create an HVDC line and two converter stations from two generators or two loads.

- powsybl-short-circuit: no release for the moment, all merged code has been transferred in powsybl-core. The CGMES importer will say here for the moment. What about the asymmetrical extensions ?

- powsybl-enstoe: support of GLSK importer from UCTE file and CIM file. Ongoing work to support it in pypowsybl after.

- POC on optimization for long-term studies.

 

Refactoring :

-          Merging of powsybl-single-line-diagram and powsybl-network-area in a multi-module Maven project  including CGMES GL support and GPS extensions ;

-          Merging of powsybl-balances-ajustement and powsybl-enstoe in a multi-module Maven project ;

-          Open-loadflow reorganization in a multi-module Maven project. It could be renamed as powsybl-open-simulator, with:

1)      powsybl-open-simulator-matrix, transfer of com.powsybl.math.matrix from powsybl-core

2)      powsybl-open-simulator-network with the LfNtework renamed OsNetwork

3)      powsybl-open-simulator-core with the equations and maybe more

4)      powsybl-open-loadflow with implementations of LF, SA and security analysis.

 

Roadmap

I will update the roadmap after this meeting.

- A EQ full export: issue about persistence of RDF ids.

- The CIM conversion of measurements (WIP, data are missing).

- A power factory importer.

- Pypowsybl

- Time series: some discussions with Alliander, Sogno and Artelys about time scale DB.

- Network area diagam: what’s next ?

- 2022: we want to finish the Dynawo integration.

- A clean support of the CIM-CGMES SCADA use-case.

- State estimation.

- Other subjects ?
