CGMES

Line and substation containers

• Conversion.getFictitiousVoltageLevelForNodeInContainer(String containerId, String nodeId) was removed.
  Instead, use SubstationIdMapping.getFictitiousVoltageLevelForContainer(String containerId, String nodeId).

• CgmesModel has two new methods that should be implemented if you have classes implementing this interface:

  • Optional<String> node(CgmesTerminal t, boolean nodeBreaker);
  • Optional<CgmesContainer> nodeContainer(String nodeId);

• SubstationIdMapping was renamed to NodeContainerMapping.
  As a consequence, method substationIdMapping() of com.powsybl.cgmes.conversion.Context was renamed to nodeContainerMapping().

Simplifying unit tests

The following methods of CgmesConformity1ModifiedCatalog, were removed:

• miniGridNodeBreakerMissingVoltageLevel()
• miniNodeBreakerCimLine()
• miniNodeBreakerSwitchBetweenVoltageLevelsOpen()
• miniNodeBreakerJoinVoltageLevelSwitch()
• miniNodeBreakerJoinVoltageLevelTx()
• miniNodeBreakerSubstationNode()

They were used for unit testing, but they relied on big CGMES files ; this slowed the tests execution. If you still need to use them, you can retrieve the methods at this URL and the corresponding CGMES files in this directory.

UndirectedGraph notification deactivation

Starting from this release, default implementations for addVertexIfNotPresent and vertexExists methods have been removed from UndirectedGraph interface.
