pv array mppt model doesn't work as expected

this simulation is a pv array connected with a buck boost converter and a mppt algorithm, the problem is even though the pv plots are correct the voltage does'nt seem to be tkane into consideration when calculation the final output power, and the load power and pv array power should be the same but they're not and idk why i checked pretty much everything

Hi Diana,

I understand that in “PV array connected to buck-boost converter model”, the voltage is not being considered in the calculation of the final output power.

You can debug this issue by considering the following things:

• Ensure that the voltage across the PV array is being accurately measured and fed into the MPPT algorithm. Incorrect voltage measurement can lead to incorrect power calculations.
• Check the implementation of the MPPT algorithm. Ensure that it correctly adjusts the duty cycle of the buck-boost converter based on the voltage and current inputs to maximize power output.
• Verify that the load is properly matched to the PV array output. An incorrect load can lead to power mismatches.

You may for refer to the following link which shows the implementation of PV system with Buck Boost based MPPT System
