How do I test for solar irradiation variation from 1000w/m2, 800w/m2, 400w/m2?

I am new to the field of power electronics. I model maximum power point tracking perturb and observe algorithm with a buck-boost converter.

I want to test for various solar irradiance, please how do I go about this?

I want to testfor various solar irradiation to be able to obtain the voltage, current and power, how can I do this ?

I also don’t know if my c-script for the MPPT is right or wrong.

Attached to this question is my model for the MPPT perturb and observe with a buck-boost converter.

Hi, I’m already develop a circuit that you mention.

Use that YouTube reference: https://youtu.be/m74lMUmmbX0

That is a master degree class, and that channel has a continuity of the development of simulation like that you want.

If help you, I suggest you subscribe. The only problem is the language of the video, but is simple you find the papers of Marcelo Vilalva for read and implemented youself (there’s also a plecs demo based in that work).

Thank you. I will subscribe to the channel and learn more.
