RenPlant#
Renewable plant control group.
Common Parameters: u, name
Available models: REPCA1
REPCA1#
REPCA1: renewable energy power plat control model.
The output of the model, Pext and Qext, are the increment signals
of active and reactive power for the electrical control model.
Notes for PSS/E DYR parser:
If ICONs M+1 and M+2 are set to 0 when using generator power, an error will be thrown by the parser, saying "<REPCA1> cannot retrieve <bus1> from <ACLine> using <line>: KeyError('Group <ACLine> does not contain device with idx=False')". Manual effort is required to run the converted file. In the REPCA1 sheet, provide the idx of a line that connects to the RenGen bus.
PSS/E enters ICONs M+3 as a string in single quotes. The pair of single quotes need to be removed, or the conversion will fail.
