wlim_series PySAM

Dear Paul,
In my CSP tower model in PySAM I would like to do something similar to "Grid Limits" in the desktop version. I have read the information and I think the option that comes closest to that is to set is_wlim_series = 1 and then specify using a list or another iterable wlim_series. That's right? I have tried, but it does not limit the power output, it keeps coming out the same as always.
Here just a piece of my code.
system_model_csp.SystemControl.is_wlim_series = 1
system_model_csp.SystemControl.wlim_series = np.ones (8760) * 50
system_model_csp.execute ()
Any help or advice, I would really appreciate it.
Greetings,
Maria

Hi Maria,

The 'wlim' variables are inputs to the CSP system controller. I think you want the inteconnection limit variables, which are 'enable_interconnection_limit' (number: 0=false, 1=true) and 'grid_interconnection_limit-kwac' (number: AC kW limit).

If you want a time series limit instead of a single limit, you can use 'grid_curtailment' (array: AC MW limit for each time step).

One way to find the names of these variables is to find them in SAM's user interface, and then use the LK script editor to list the variables: On the File menu, click New script, and then in the script editor, click Variables at the top of the window. You can then search variables by their labels to find the variable name.



Best regards,
Paul.

Thank you very much Paul. Those commands that you indicate are not in the Pysam information? ( nrel-pysam.readthedocs.io/en/master/modules/TcsmoltenSalt.html ). I have looked for it there, but it is not there. 

Perhaps the information is not up to date yet.

Thank you very much for your help.

Hi Maria,

Those variables are inputs to the Grid module, which is described here: nrel-pysam.readthedocs.io/en/master/modules/Grid.html

For the equivalent Molten Salt Power Tower / Single Owner Configuration in SAM, run TcsmoltenSalt, Grid, Singleowner as described here: nrel-pysam.readthedocs.io/en/master/Configs.html

Best regards,
Paul.
