Issue with Power Adjustment of Solar Module

[lin-1l1]

Dear Andes developers,

I have reviewed the "Change Setpoint" example and would like to adjust the power output of the solar module in the ieee14_solar.xlsx file in a similar manner. I have attempted to adjust the real power output of the solar energy in the TDS. However, despite consulting the REPC, REEC, and REGC sections of the manual and adjusting some parameters (such as Plant_ref, Pline0, and Ipcmd0), the output power does not seem to change.

In this situation, I would like to inquire about which parameters should be controlled to effectively alter the real power output of the solar energy? Are there any other aspects I should consider or areas I might have overlooked?

Thank you very much for your valuable assistance!

Thank you for the questions! Changing the reference points for renewable generators are much more involved. I will make you an example in the coming week.

Dear Professor Cui
Thank you very much for your response and willingness to provide an example. I truly appreciate your assistance with this matter.

There isn't an elegant way to change the active power reference. But you can hack it like this:

In REGCA1, the active power output Pe is computed by Ipcmd * v, and Ipcmd = Ipcmd0_LVG.

Ipcmd0_LVG is a type of constant service. You can impact ' Pe ' by changing the value of Ipcmd0_LVG.v[:]. At steady-state, the desired Pe can be achieved by setting Ipcmd0_LVG.v[:] = desired_Pe / voltages.

Thank you, Professor. I would like to express my gratitude once again for providing the example, which has been immensely helpful for my research.

I have a few new questions that I would like to consult you about (regarding ROCOF and inertia constant H, among others). Would you be available to answer them? If possible, could we communicate via email?

Thank you for taking the time to address my questions, and for your valuable time and assistance.

Thanks! It would be helpful to post it to Discussion for future reference. For anything non-public, feel free to email me!
