v4.6.1

What's Changed

CSA-profiles importer

• The CSA-profiles importer now supports AngleCnecs (#818)
• When importing CNECs from an AssessedElement, if a given contingency cannot be associated with the AssessedElement, remaining contingencies are no longer ignored (#815)

Full Changelog: v4.6.0...v4.6.1

v4.6.0

What's Changed

Compatibility

• FARAO now only supports Java 17 and higher (#805)
• FARAO is now compatible with PowSyBl-core version 6.0.1 (#805)

CRAC API

• It is now possible to define an InjectionSetPoint that acts on a ShuntCompensator's section count (#802)
• The remedial actions adders' add() method is now common and returns a RemedialAction. This allows the CRAC factory user to create remedial actions in a more generic way (#787)

RAO API

• The OptimizationState enum has been removed in order to simplify the API. When querying the RaoResult object, the user now shall use Instant instead. (#806)

Search-tree RAO

• Bug fix for network actions that have no operator defined (#791)
• Other minor bug fixes (#796, #813)

Voltage & angle monitoring algorithms

• The voltage monitoring algorithm can now apply remedial actions to try to solve constraints (#776, #800)
• The angle monitoring algorithm now supports AngleCnecs defined on a Bus (#808)
• Both algorithms now have better logs (#797)

CSA-profiles importer

• The CSA-profiles importer now supports VoltageCnecs (#781)
• Minor bug fixes (#795, #798, #801)

Others

• It is not possible to install FARAO using iTools anymore (#792)
• Some Sonar issues were addressed (#803)
• It is now possible to enable linear optimizer output by activating "trace" level in "Technical logs" (console only) (#814)
• Parallelization bug fixes (#810)

Full Changelog: v4.5.0...v4.6.0

v4.5.1

Enable better debugging in release v4.5.0 by:

• enabling solver output when TechnicalLogs.TRACE is activated
• better catching exceptions when parallelizing computations

v4.5.0

What's Changed

New CSA-profiles CRAC importer

This importer respects the ENTSO-E specification for CIM CSA-profiles v2.2.
For now, supported objects are:

• Contingencies
• Flow CNECs
• Topological remedial actions (only opening switches for now, and only on-instant & on-contingency-instant usage rules)
• Injection set-point remedial actions (only on-instant & on-contingency-instant usage rules)
• PST range actions (only on-instant & on-contingency-instant usage rules)

CIM CRAC importer

• The importer is now more permissive on where it should find contingencies & flow CNECs. Read about it here: #784

Remedial action optimisation

• The RAO is now faster thanks to an optimisation of the search-tree algorithm. Read about it here: #766
• A minor bug has been fixed inside the search-tree: #778
• Misc issues with automaton simulation have also been fixed: #777

CRAC API

• It is now possible to define remedial actions that are available after a constraint on a voltage CNEC. Read about it here: #775

v4.2.4.1

Correct a bug in max-cra-per-tso where all range actions were counted (not only the ones belonging to TSO)

v4.2.6

What's Changed

• Demote some logs by @pet-mit in #739
• Refacto parameters by @Godelaine in #736

Full Changelog: v4.2.5...v4.2.6

v4.2.5

What's Changed

• Improve AUTO CNECs optimization by @pet-mit in #726
  BREAKING CHANGE If AUTO CNECs exist with no associated AUTO RAs, these CNECs are duplicated in the OUTAGE instant in order to be secured by the preventive RAO. Implemented for the CIM CRAC creator.
• Fix hvdc setpoint by @pet-mit in #723
  BREAKING CHANGE When disabling AC emulation on an HVDC, its original (AC-emulation) set-point has to be computed and set before running sensitivity analysis, in order to ensure convergence

• Bump powsybl and its dependencies versions by @phiedw in #731
  PowSyBl version bump
• Consider ARAs in 2P by @Godelaine in #728
  BREAKING CHANGE Second preventive RAO now behaves a lot better when mixed with AUTO perimeters
• Add messages to CNE exceptions by @pet-mit in #732
