How to implement step change on PV and WTG 2nd generation dynamic models? Is it only by changing the values of vref and Pref?

Why don't you try that and find out if it works?

it's not working.

I have created a tool named "DMView" to run voltage response test including voltage step change test.

Could you please share your tool again, link has expired?

thanks a lot!!

Thanks for the tool. Can you share the redirect module please. I'm getting error of no module named redirect for the dmview.py file and TOOLS\FS.py file.

Take a look at the VARs available in the reeca, reecb, reecc models. Changing those VARs can be used to stimulate a step change for getting response for the renewable models. If the VARs are not available, you can always write a machine model that changes the wpcmd, wqcmd to get your desired simulation response.

I changed the VAR(L) of REPCAU1 model and it's doing a Voltage step. Thanks.

Now for changing p and q set points, you can write a model to change the wpcmd, wqcmd which will give you the desired response

An equivalent approach is to change network voltage and/or frequency at the POI (point of interconnection). Use the playback model PLBVFU1 to run such simulations. Check the posting "PLBVFU1 Playback model" for more info, and the PTI manual, Models -> Generator.

I'm changing the value of CON(J+8) in the REECBU1 to obtain a step response in the terminal voltage of the PV (by 2-3%) while enabling the refflag and fflag in the REPCAU1. No changes in the voltage response.

jconto, I used playback model simulation and it worked. Thanks for suggesting.
