A PV module is working at STC for 15 s, then at G= 500 W/m2 & T= 50° for 10 s, and finally at
the STC again for 10 s.
Assume that the PV module was operating initially at open circuit voltage at STC, write a
MATLAB code for an MPPT algorithm to extract the maximum power for STP260 – 24/Vd PV
module using a PV model block built in Simulink using the P&O method.
The algorithms above should be executed every 0.1s. Try different values for the step voltage (0.1
V, 0.5 V, and 1 V). Plot the voltage and power waveforms for the three cases on the same graphs;
one for power and one for voltage.
Comment on the effect of increasing the step voltage.
(Note: It is not required to implement the MPPT algorithm using a DC converter. You can replace
it with a controlled voltage source available in Simulink)
This is kind of how the design should look, I think the part in blue are wrong.
