PV curve tracing under partial shading conditions in SIMULINK

[@sivaprasad-cl7xp]

sir, I had used the PV array which is in MatLab Simulink, and executed it with one panel. it worked. when I tried to connect two panels in series I am getting NAN values. please help me

[@HadeedSher]

Remove the blocking diodes and use continuous sampling

[@auualkinany9719]

what is the purpose of capacitance in parallel connection with each pv module?

[@HadeedSher]

It eliminates the convergence problem in the software.

Please Sir, '' PV curve tracing under partial shading conditions in SIMULINK'' help me. I am applying the way of your video file, but finally not run. Please, tell me.

[@zinmarwinko8244]

I cannot connect when two solar modules are connected in series connection.

[@HadeedSher]

It is very straightforward

[@sivaprasad-cl7xp]

Als can i replicate it for a 2 X 2 pannels i.e., 2 in series along with 2 in parallel. if so, what are the things need to be changed

[@HadeedSher]

You need to connect the panels individually rather than specifying it in MATLAB. Also connect bypass diode and a small capacitor in parallel.

[@sivaprasad-cl7xp]

may i know which matlab version you have sir. so that i can share my work with you

[@HadeedSher]

I am using 2019 now.

[@sivaprasad-cl7xp]

Can you share this simulink file sir
