Production Power Station Aggregation Mode

Units:-
Default Value:0
Validation Rule:In (0,1,2)
Description:Automatically create Power Station objects by aggregating Generators

This option controls the automatic creation of Power Station objects during the data processing phase of the simulation. The following options are available:

None (value = 0, default)
Do not create any Power Stations. Existing Power Station objects are not affected.
Name (value = 1)
Create Power Station objects by aggregating Generator objects according to names.
Location (value = 2)
Create Power Station objects by aggregating Generator objects according to location.


Aggregation by Name (value = 1)

This auto-aggregation method uses the naming convention of the objects to group Generators into a collection of Power Station objects. A high-level overview of this process is as follows:

  1. Group all Nodes by name, removing numeric values from their names - for example Nodes "SA" and "SA1" will be grouped together.
  2.  Get all Generators associated with those nodes.
  3. Group these Generators by name, removing numeric values from their names - for example Generators "Big Coal1" and "Big Coal2" will be grouped together.
  4. Get the memberships for these Generators and ensure that they match. If a Generator doesn't have the correct number of memberships then it will be rejected from this possible Power Station candidate.
  5. Create the Power Station object, with its name based on the grouped Generators' name, e.g. "Big Coal".

Aggregation by Location (value = 2)

This auto-aggregation method uses the location (Longitude and Latitude) of the Nodes to group Generators into a collection of Power Station objects. A high-level outline of this process is as follows:

  1. Group all Nodes by location (Longitude and Latitude).  If the Node does not have Longitude and Latitude defined, then it will be omitted from this process.
  2.  Get all Generators associated with those nodes.
  3. Get the memberships for these Generators and ensure that they match. If a Generator doesn't have the correct number of memberships then it will be rejected from this possible Power Station candidate.
  4. Create the Power Station object, with its name based on the Node name and the first Generator's name in the group.

Please note that existing power station objects will be used as defined and any generators that are members of those objects will be omitted from the auto-aggregation process.


The "Auto Power Station" diagnostic is a useful tool to see exactly what Power Station objects have been created and their Generator memberships.  This diagnostic can be enabled using the hidden parameter "PowerstationAggregationAuto_Diagnostic" - see here.  This will output a file called "Power Station Data.txt" to the input folder location and will contain the relevant object and membership details.
