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

Release candidate of powsybl-core available on Friday Release v4.9.0 (expected: 2022-06-15) · powsybl/powsybl-core (github.com), with as major features:

-          CGMES 2.4.15: fixes and improvements after a lot of tests performing for full export validation on real networks.

-          CGMES 3.0: improvements, still a beta feature. Do not hesitate to test this feature and provide feed-back.

-          Configuration: add methods to get the specific parameters of a sensitivity or security analysis.

-          Configuration: add import/export parameter possible values.

-          IIDM: fictitious injections.

-          Modifications: fix add voltage level on a line.

-          Power Factory importer.

-          PSSE importer.

-          Triple store: remove Jena implementation.

-          Many quality commits.

-          Expected: increase of short-circuit API to support elementary computations.

-          Excepted: IIDM converter API merged with IIDM network API.

Next release will be on April the 23^rd.

-          EMF based on the destructive merge and not on the merging view?

-          Operational limit set support.

-          Support of protections and automatons in IIDM network.

-          On-going work abound a new security analysis with actions (Security analysis with remedial actions · Issue #2015 · powsybl/powsybl-core (github.com)) + a WIP PR [WIP] add remedial actions for security analysis by EtienneLt · Pull Request #2095 · powsybl/powsybl-core (github.com)

Other repositories:

-          Florian: single line diagram and network area diagram.

-          Sylvain: pypowsybl.

-          OLF:

Support of all type of contingencies for AC and DC sensitivity analysis and security analysis.

New incremental transformer voltage control outer loop.

-          powsybl/powsybl-starter (github.com)

-          powsybl/powsybl-benchmark (github.com)

-          IIDM C++, no release for the moment, still supporting until IIDM 1.5.0, WIP.

-          WIP: update of powsybl-tutorials

-          WIP: non regression testing

Roadmap:

-          Integration of Dynawo : redesign for next release, then work by Dynawo team ;

-          Time series : benchmarks on time scale DB ;

-          Network modifications improvement -> we need to write issues in order to have a collaborative organization on that topic ;

-          New security analysis API with actions (Security analysis with remedial actions · Issue #2015 · powsybl/powsybl-core (github.com)).

-          Increasing the shortcircuits API: REX after models integration and work around parameters

-          TODO: fusion of balances-ajustement and powsybl-enstoe?

-          TODO: we are late about documentation.

-          Multi component results for security analysis API.

-          The support of EMF in pypowsybl

-          Discussion about fictitious switch in CGMES

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

See you soon !

Hi everybody,

I am just received that information today, in French sorry for that. It seems that Power Info is going to use Powsybl in CIMdesk and CIMSpy. What a great news !

Best regards.

Hi everybody,

Our next TSC meeting will be on April the 7^th, 13h30, on Teams: Cliquez ici pour participer à la réunion

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

Release candidate of powsybl-core available since a week Release v4.8.0-RC1 · powsybl/powsybl-core (github.com), with as major features:

-          CGMES: the ability to export in version 2.4.15 or 3.0, as a beta feature. Many functional tests are in progress.

-          CGMES export after topological changes.

-          Fix about the HVDC active power set point interpretation.

-          IIDM: some fixes linked to the delayed validation.

-          IIDM: tie line implementations have changes for line characteristics computation.

-          Loadflow: add HVDC AC emulation parameter -> remember to use it in the open-loadfow.

-          Loadflow: other improvements linked to pypowsybl.

-          Math: math-native 1.2.0.

-          Improvements in PSSE, PowerFactory and Matpower importers.

-          Scalable: support of empty scalable.

-          Sensitivity: new sensitivity function types.

-          And as usual some quality improvement.

Next release will be on April the 23^rd.

-          IIDM converter API: will be merge with IIDM network API?

Other repositories:

-          Florian: single line diagram and network area diagram.

-          Sylvain: pypowsybl.

-          OLF: support of HVDC AC emulation for AC LF and AC SA, some fixes linked to factor status in DC sensitivity analysis, fix of transformer voltage control in after generator control mode, fix of multi components DC LF, etc. Some other fixes are expected for the next release, as we are performing a lot of tests and we have many users through pypowsybl: it will lead to a robust engine.
