Error 130 | [Various software] | Could not find internode variable


Relevant software:

PSS®E
PowerFactory
PSCAD™


Emitted message:

Could not find a matching value for this internode variable in any linked task

Description:​

This error indicates that a Node in your simulation is trying to use an Internode Variable, but the gridmo Engine could not find a matching variable with that name being exported from any of the Nodes linked to it.

Internode Variables are used to pass data between different Nodes in a gridmo project.

danger

This may cause the task to fail as it cannot resolve a required input variable.

Some tasks, such as Plot, Analysis and Table Nodes will continue to generate outputs, even if missing one or more Internode Variables.

Possible impact:​

  • Results may be incomplete or incorrect if the missing variable is being plotted or analysed.
  • Some tasks will not run if the value is required for the task, such as a PSCAD task that imports an Internode Variable from a PSS/E Static or PowerFactory Static Node.

Potential fixes:​

To resolve this error, you need to ensure the Internode Variable is correctly defined and exported from a linked Node.

  • Check for OUTPUT command: Ensure that the source Node (the one that should be providing the data) has an OUTPUT command and that the NAME= argument matches the Internode Variable name in the consuming Node (e.g. {{variable_name}}).
  • Check for typos: Verify that the Internode Variable name in the consuming Node (e.g. {{variable_name}}) exactly matches the name in the OUTPUT command of the source Node. Variable names are case-sensitive.
  • Check Node linking: Confirm that the Node exporting the variable is correctly linked to the Node that is trying to use it on the Flow canvas.
  • Check for disabled Nodes: Make sure the Node that is supposed to export the variable is not disabled.

Internode Variables are case sensitive.
