IIDM & XIIDM 1.2 evolutions
Shunt compensators can now be regulated. New attributes (regulation (boolean), targetV (double), targetDeadband (double) and regulatingTerminal (Terminal)) have been added to ShuntCompensator and can be set and accessed. However, to serialize or deserialize a shunt compensator with any of these attributes with a non-default value, IIDM-XML version 1.1 must be used. Otherwise, the serialization and deserialization will fail.
To know more about these attributes and their default values, go to the documentation page of ShuntCompensator.
The attribute targetDeadband in RatioTapChanger and PhaseTapChanger is now required if RatioTapChanger.regulating is set to true or PhaseTapChanger.regulationMode is not set to FIXED_TAP.
If targetDeadband is not defined in these cases, an exception will be thrown. Hence, add the line:
tapChangerAdder.setTargetDeadband(0.0);to keep the same behavior as before. Of course, you can also add another value if it is more appropriate to your use case. At any rate, in the cases described above, targetDeadband should not be Double.NaN.
A new optional attribute ratedS in TwoWindingsTransformer and ThreeWindingsTransformer.Leg has been introduced to model apparent power.
If ratedS is not set to Double.NaN, it should not be strictly inferior to 0.0.
TODO
TODO
The attribute nodeCount in the nodeBreakerTopology element has been deleted from this IIDM-XML version: it is not possible to pre-create vertices in the voltage level's graph in advance as this design was prone to allocation errors. Graph's vertices are created on the fly while attaching network components (a connectable equipment, a switch or an internal connection). When reading an IIDM-XML file in a prior version, the attribute nodeCount will be ignored. When writing an IIDM-XML file in a prior version, the attribute nodeCount will be written based on the number of vertices in the voltage level's graph.
