Issue with PV Panels Generic not responding to Irradiation profile

Question

Hi everyone,

I am trying to implement an irradiation profile from a .txt file for the PV Panels Generic block using the macro variable in HIL SCADA. I followed the exact same approach as in the WindSpeed example, using the same code structure but with my own references. I am not getting any errors, and in the SCADA input, I can see that the irradiation variable changes according to my text file. However, the output power of the panel does not change. It seems like the input is not being received.

Has anyone encountered this issue before? Any suggestions on what might be going wrong?

Thanks in advance!

Hi Leonardo,

If you can see that the SCADA input corresponding to irradiation is changing according to the desired readings from the text file, the issue is not related to component not responding to irradiation profile. 

It is hard to guess exactly what is causing the problem in your model without seeing it. Here are some common mistakes:

1. You forgot to enable the PV Power Plant
2. The parameters of the grid (voltage and frequency) are not set according to nominal parameters of the PV power Plant.

The easiest way to check this is to open PV Power Plant Interface Subpanel in HIL SCADA and check the DER state and whether there is any alarm message:
