Header
GLSK Definition

GLSK in CSE format are defined within XML files. This format is used for the CSE region.
The main tag of the document is GSKDocument.

<GSKDocument DtdVersion="5" DtdRelease="0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="gsk-document.xsd">

Contents of the header:

DocumentIdentification: ID for the document
DocumentVersion: version of the document
DocumentType: standard code defining the document type*. In the example above, “B22” means “Generation and load shift keys document”.
ProcessType: standard code defining the process type*. In the example above, “A01” means “day ahead”.
SenderIdentification: ID of the sender of the GLSK document*. Usually an ENTSO-E EICode.
SenderRole: standard code defining the role of the sender*. In the example above, “A36” means “capacity coordinator”.
ReceiverIdentification: ID of the receiver of the GLSK document*. Usually an ENTSO-E EICode.
ReceiverRole: standard code defining the role of the receiver*. In the example above, “A04” means “system operator”.
CreationDateTime: document creation time.
GSKTimeInterval: time interval of applicability of the GSK document.
Domain: ID of the geographical applicability of the document. Usually an ENTSO-E EICode.

*Refer to the ENTSO-E website for the complete reference documents. You can find a complete list of codes in the XSDs. Note that codes that begin with “Z” are region-specific.

GLSK Definition

Proper GLSK are defined within the tag TimeSeries. Generally, every TSO defines its own TimeSeries.

<...Block>
    <TimeSeriesIdentification v="1"/>
    <BusinessType v="Z02"/>
    <Area v="REGION_EIC" codingScheme="A01"/>
    <Name v="REGION_NAME"/>
    <TimeInterval v="2022-11-26T18:00Z/2022-11-26T19:00Z"/>
    <...Block></...Block>
</TimeSeries>

TimeSeriesIdentification: unique ID of the TimeSeries in the document.
BusinessType: code defining the type of network element to be shifted:
- Z02: generators
- Z05: loads
Area: geographical applicability of the TimeSeries. Type is given by the content of codingScheme:
- A01: the coding scheme is the EICode, maintained by ENTSO-E.
- A02: the coding scheme used for Common Grid Model Exchange Standard (CGMES).
- A10: the coding scheme for the preceding attribute is the Global Location Number (GLN 13) or Global Service Relation Number (GSRN 18), maintained by GS1.
- … other region-specific codes*.
Name: human-readable name of the region.
TimeInterval: time interval of applicability of the GLSK document.
…Block: one or multiple GLSK blocks containing actual values, can be of different types, explained in the following paragraphs.

*Refer to the ENTSO-E website for the complete reference documents. You can find a complete list of codes in the XSDs.

Manual GLSK

The ManualGSKBlock tag can be used to define manually all the UCTE nodes associated with their weight within the GLSK.

<ManualGSKBlock>
  <Factor v="1"/>
  <Node>
    <Name v="Node1"/>
    <Factor v="0.19"/>
  </Node>
  <Node>
    <Name v="Node2"/>
    <Factor v="1.99"/>
  </Node>
  ...
</ManualGSKBlock>

Factor: a multiplier for all following factor values.
Node: list of custom GLSK definitions
- Name: UCTE ID of the node on which the generation/load should be shifted
- Factor: the shift key for the given node

Proportional Block

The PropGSKBlock and PropLSKBlock tags can be used to define proportional GLSK.
PropGSKBlock affects generators, and PropLSKBlock affects loads.

<PropGSKBlock>
  <Factor v="0.5"/>
</PropGSKBlock>
<PropLSKBlock>
  <Factor v="0.5"/>
  <Node>
    <Name v="Node1"/>
  </Node>
  <Node>
    <Name v="Node2"/>
  </Node>
  <Node>
    <Name v="Node3"/>
  </Node>
</PropLSKBlock>

Factor: a multiplier for all following factor values.
Node (optional): list of custom GLSK definitions
- Name: UCTE ID of the node on which the generation/load should be shifted
Note: if no Node is defined in the block, all generators/loads in the network (for the given region) are affected

Reserve Block

The ReserveGSKBlock tag can be used to define remaining capacity GLSK.

<ReserveGSKBlock>
  <Factor v="1"/>
  <Node>
    <Name v="Node1"/>
    <Pmin v="0"/>
    <Pmax v="-29"/>
  </Node>
  <Node>
    <Name v="Node2"/>
    <Pmin v="0"/>
    <Pmax v="-29"/>
  </Node>
</ReserveGSKBlock>

Factor: a multiplier for all following factor values.
Node: list of custom GLSK definitions
- Name: UCTE ID of the node on which the generation/load should be shifted
- Pmin: minimum active power target
- Pmax: maximum active power target (can be < Pmin, if shifting needs to decrease generation / increase load, like in example above)

Merit-order Block

The MeritOrderGSKBlock tag can be used to define merit-order GLSK.

<MeritOrderGSKBlock>
  <Factor v="1"/>
  <Up>
    <Factor v="1"/>
    <Node>
      <Name v="NodeUp1"/>
      <Pmax v="-360"/>
    </Node>
    <Node>
      <Name v="NodeUp2"/>
      <Pmax v="-384"/>
    </Node>
    <Node>
      <Name v="NodeUp3"/>
      <Pmax v="-411"/>
    </Node>
  </Up>
  <Down>
    <Factor v="1"/>
    <Node>
      <Name v="NodeDown1"/>
      <Pmin v="-122"/>
    </Node>
    <Node>
      <Name v="NodeDown2"/>
      <Pmin v="-260"/>
    </Node>
  </Down>
</MeritOrderGSKBlock>

Factor: a multiplier for all following factor values.
Up: list of nodes used to increase generation / decrease load
- Factor: a multiplier for all Up factor values.
- Node: list of custom GLSK definitions, sorted by ascending merit order
  - Name: UCTE ID of the node on which the generation/load should be shifted
  - Pmax: maximum active power target on the node
Down: list of nodes used to decrease generation / increase load
- Factor: a multiplier for all Down factor values.
- Node: list of custom GLSK definitions, sorted by ascending merit order
  - Name: UCTE ID of the node on which the generation/load should be shifted
  - Pmax: maximum active power target on the node
