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.

-          powsybl/powsybl-starter (github.com)

-          powsybl/powsybl-benchmark (github.com)
