I've made a simple simulation on Simulink consisting on a PV panel, dc-dc converter, resistive load and a function block acting as a MPPT running the code for grey wolf algortihm
When I increase the solar radiance, the current from the panel (2nd graph) starts fluctuating. When i decrease the the solar radiance, the voltage from the panel (4th graph) starts to fluctuate. Further more, if the change the value of the load resistor to 100 ohms from 10 ohms, both the current and voltage goes crazy.
I have no idea what is causing this and was hoping someone could point out my mistake. I have attached the pictures below along with the simulink file. I am willing to provide more information if needed.
You need to optimize your duty cycle parameters appropriately. You can refer to this paper:
