Hi everybody,

Our next TSC meeting will be on September the 15th, 13h30, on Teams: Cliquez ici pour participer à la réunion

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

Next release is for today. This release of powsybl-core 4.10.0 contains:

-          [IIDM] limit getters return optionals. It is a breaking change.

-          [IIDM] the SLD extensions are moved to powsybl-core.

-          [IIDM] parameters are moved to commons.

-          [IIDM] allow to serialize false as redundancy.

-          [Modification] create bay feeder and create branch feeders. Add utility methods to retrieve the connectable order positions.

-          [Modification] transform a tee point into a switching voltage level.

-          [Modification] renaming attach to createLineOnLine and connectVoltageLevelOnLine.

-          [Conversion] importer and exporter refactoring.

-          [CGMES] many improvements, see release notes Releases · powsybl/powsybl-core (github.com)

-          [PowerFactory] improvements, see release notes Releases · powsybl/powsybl-core (github.com)

-          [Short-circuit] clean and refactoring.

-          [Security analysis] a first beta version of the security analysis API with remedial action + switch action + line connection action and phase tap changer tap position action.

-          [Sensitivity analysis] add contingency status in the result.

-          [Sensitivity analysis] support of three windings transformer as functions and variable.

-          + quality

Release train 1.3.0, based on powsybl-core 4.10.0

-          OLF, SLD, NAD, Dynawo, balances ajustement and entsoe expected next week, release train expected next week too.

Other repositories:

-          Florian: single line diagram and network area diagram.

-          Sylvain: pypowsybl.

-          OLF:

Support of shunt compensator G

Introduce plausible target voltage parameters

New GraphConnectivity API

Support of dangling line as function reference in sensitivity analysis

[Excepted] Support of switch contingency in sensitivity analysis.

[WIP] Work on generators connected to the same bus but controlling two different buses -> change the exception by a warning first.

-          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: non regression testing

-          ENTSOE: flow decomposition following ACER methodology.

-          Dynawo: redesign.

Roadmap:

-          IIDM: Sets of operational limits. We found limitations in using private extension currentLimitsPerSeason and properties.

-          IIDM: modeling of protections.

-          Time series : benchmarks on time scale DB ;

-          Network modifications: creation of voltage level from scratch.

-          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

-          Other subjects?

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