IIDM & XIIDM 1.2 evolutions
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.
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 ShuntCompensator API has been greatly modified to support non linear shunt compensators and linear shunt compensators. Custom implementations of this API must be modified as well to compile. Furthermore, methods have been moved or deleted, their uses must be modified as well. To know more, please go to the Javadoc or to the shunt compensator's documentation page.
Please refer to the IIDM-XML XSD schema for more details.
fictitious is now an optional boolean attribute for every classes extending Identifiable.
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.
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.
