This is the first RAO release un its new "PowSyBl Open RAO" name!

PowSyBl move

• Some modifications of the code in order to adapt to the move (#853, #860, #864, #867, #868, #873)

Full Changelog: v5.0.0...v5.0.1

v5.0.0

What's Changed

Major announcements

• This is the last farao-core release! The code base will be migrated to the PowSyBl space and will be published under the new name "PowSyBl Open RAO". A link will be added here once it is done.
• In preparation for the move, the virtual-hubs code has been moved to farao-core. The repository farao-virtual-hubs will be archived. (#851)

Compatibility

• FARAO is now compatible with PowSyBl-core version 6.1.0 (#852, #858)

CRAC API

• "Instant" is now an object, not just an enum. Different Instant instances are now carried by the CRAC instance (you may need them to query the RaoResult object). This will allow the CRAC in the future to contain multiple curative instants, in order for them to be optimized sequentially by the RAO. (#825)
• The TO_BE_EVALUATED usage method has been removed. This shall have no effect on you application, unless you add RAs to the CRAC outside CRAC creators. (#779)

RAO

• The RAO can now update PTDF values used in relative margins computations after every topological or PST tap change. Thus, some parameters of the RAO have changed. Read about them in the description of the PR and in the doc (here and here). (#811)

CSA-profiles importer

• The importer now supports header version 2.3 only (#842)
• Topological actions can now be defined with an OPEN or CLOSE action (#847)
• Assessed elements can now be defined with ConductingEquipment instead of OperationalLimit (#840)
• The importer now handles SSI and SSH profiles, that can override information found in other profiles (#849)
• AssessedElements are now imported even if they are not marked as critical (#856)
• Some minor improvements and bug fixes (#845, #854, #855)

Angle and Voltage monitoring algorithms

• The algorithms now augment the RaoResult instead of generating specific result objects / files. The old "run" methods and result objects / files are deprecated and will be removed in a future release. To help you migrate to the new API, refer to our official documentation: angle monitoring, voltage monitoring. (#841)

SWE CNE

• The SWE CNE exporter API has been adapted to the angle monitoring update. The exporter is now only callable with the augmented RaoResult object. To help you migrate to the new API, refer to our official documentation. (#848)

Bug fixes

• A bug in the MIP "unoptimized CNEC" filler was fixed (#850)
• Some minor improvements and bug fixes (#844)

Housekeeping

• Some code was made common between CRAC serializers and deserializers (#843)
• Some minor improvements (#846)

New Contributors

• @OpenSuze made their first contribution in #825
