Features

Generic Area

An Area is a geographical zone of a given type. It is composed of a collection of voltage levels, and a collection of area boundaries.

The area type is used to distinguish between various area concepts of different granularity. For instance: control areas, bidding zones, countries...

You can find more information on this feature in the documentation.

Example, in XIIDM

Here is the XIIDM serialization of the generic area "BidZoneName" of type "BiddingZone", with:

• one voltage level, of id "VL1";
• two area boundaries:
  • on the terminal of the side one of "L1", declared as AC;
  • on the dangling line DL1, declared as DC.

    <iidm:area id="BidZoneId" name="BidZoneName" areaType="BiddingZone">
        <iidm:voltageLevelRef id="VL1"/>
        <iidm:areaBoundary ac="true" type="terminalRef" id="L1" side="ONE"/>
        <iidm:areaBoundary ac="false" type="boundaryRef" id="DL1"/>
    </iidm:area>

Note that voltage level "VL1", line "L1" and dangling line "DL1" have to be declared elsewhere in the IIDM. In this iidm:area block, only references to this elements are used.

Support of condensers

A generator may behave as a synchronous condenser, for instance if it may control voltage even if its $TargetP$ is equal to zero. Therefore a new isCondenser parameter has been added to generators. In XIIDM, this parameter is optional and equal to false by default.

Example, in XIIDM

<iidm:generator id="generator1" energySource="OTHER" minP="0.0" maxP="100.0" voltageRegulatorOn="true" targetP="10.0" targetV="400.0" isCondenser="true" node="0">
    <iidm:minMaxReactiveLimits minQ="-1.7976931348623157E308" maxQ="1.7976931348623157E308"/>
</iidm:generator>
