Features

Regulating terminal for StaticVarCompensator

StaticVarCompensator can now regulate remotely. Hence, a new field regulatingTerminal is added if it is the case when serialized in a XIIDM file. This feature can not be interpreted by prior versions.

ThreeWindingsTransformer

ThreeWindingsTransformer can now support a ratio tap changer and a phase tap changer at each of its legs. Furthermore, each leg has a magnetizing conductance (g1, g2 or g3) and a magnetizing susceptance (b1, b2 or b3). It also now has a ratedU0 attribute which indicates the theorical nominal voltage of its bus star. By default, ratedU0 equals to ratedU1 (nominal voltage at leg 1).

These features can not be interpreted by prior versions if the new attributes have not default values.

Network extensions' versions are configurable when exporting

From this release, the network extensions' XML serializers are versionable. By default, network extensions will be exported in the most recent version supported by their XML serializer and compatible with the IIDM-XML version in which the network will be exported.

New way to express voltages and angles in Node/Breaker topology

From this release, voltages and angles will not be expressed as attributes of the XML element iidm:busbarSection but in a new iidm:bus sub-element of iidm:nodeBreakerTopology.

Consequently, from XIIDM 1.1, the attributes v and angle will not be written nor read anymore and the attribute iidm:bus will be written for every electrical bus of the network with a defined voltage or a defined angle. It will be serialized as below:

<iidm:bus v="234.40912" angle="0.0" nodes="0,1,2,3,4"/>

v and angle represent the voltage and angle of this bus while the list of nodes are all the voltage level's nodes in a same electrical bus.
