Troubleshooting Final Syntax & Execution Order in IEEE-37 PV Simulation Dear Paulo,

[moneera-beep]

I have spent over 12 hours trying to get a PV daily simulation running, and I am stuck on the final execution order. I have resolved all path and CSV format errors.

The Problem: The simulation consistently shows the generic trapezoidal plot (Loadshape.Shape1) and NOT my dynamic PV_shape1s.csv file, even though my code uses Redirect ieee37_with_PV.dss.

This is because the conflicting code in the main ieee37.dss file runs first and assigns the trapezoid to all loads:

New Loadshape.Shape1...
BatchEdit Load..* daily=Shape1

I cannot edit the main ieee37.dss file (Windows permissions).

The Final Error: When I try to fix the PV script, my OpenDSS version throws the error: Unknown parameter 'Daily' for object PVSystem.PV because it dislikes the continuation line (~ Daily=MyIrrad...).

Final Request: What is the simplest sequence of OpenDSS commands to paste directly into the terminal to force the following to happen in memory, thereby ensuring my custom PV shape is used?

Compile the main script.

Delete/Remove the conflicting Loadshape.Shape1.

Execute the PV script to assign the correct shapes.

Solve.

Any help is appreciated. I need to finish this and get some rest. Thank you.

I may be missing some context, but let's try.

I cannot edit the main ieee37.dss file (Windows permissions).

You can just copy the relevant files to a folder you have write permissions. You can also download the repo at https://github.com/dss-extensions/electricdss-tst/ -- if you don't want to use Git, there is a ZIP download option in the green "<> Code" button. If should contain all relevant files related to the test/sample circuits.

Delete/Remove the conflicting Loadshape.Shape1.

You cannot really remove the LoadShape object itself after it is loaded. If the issue is just this command:

BatchEdit Load..* daily=Shape1

You could just set daily to the default (no loadshape, an empty string):

BatchEdit Load..* daily=

Note that this only affects the loads, not the PVSystem objects. I imagine you want to keep the loads constant and vary the generated power in the PVSystems -- if that's the case, it should work.

(Alternatively, you could edit the offending loadshape and set it constant values)

The Final Error: When I try to fix the PV script, my OpenDSS version throws the error: Unknown parameter 'Daily' for object PVSystem.PV because it dislikes the continuation line (~ Daily=MyIrrad...).

That's weird, maybe you have some extra non-ASCII (or maybe non-printable) character somewhere. Anyway, you can try issuing a DSS edit command (edit PVSystem.PV Daily=MyIrrad) or directly editing the specific property PVSystem.PV.Daily=MyIrrad)`. If you prefer using Python, you can also use Python objects in AltDSS .

Final Request: What is the simplest sequence of OpenDSS commands to paste directly into the terminal to force the following to happen in memory, thereby ensuring my custom PV shape is used?

For OpenDSSDirect.py, something like in a Python prompt:

from opendssdirect import dss
dss(""" 
redirect "C:/Program Files/OpenDSS/IEEETestCases/37Bus/ieee37.dss"
redirect "your_pv_script_path.dss"
BatchEdit Load..* daily=
solve mode=daily
""")

Any help is appreciated. I need to finish this and get some rest. Thank you.

Sorry I couldn't reply earlier. I hope you've managed to rest.
