Seyed Majid Hashemzadeh Thank you

Dear Adham,

Hope you are well!

To track the maximum power point understanding you need to have a method that can locate the global maximum as you may have multiple peaks under partial shading.

In this paper you please find such method: Article Enhancing the tracking techniques for the global maximum pow...

Best wishes

you have to use a MPPT which has been developed specifically to follow GMMP.

Under a partial shading , conventional MPPT methods can be trapped by identifying the global pic among the many locals pics and track one of locals pics

The MPPTs techniques can be classified in two main groups, Local and Global MPPTs. LMPPTs can be employed only to track the MPP of PV systems under UICs. They include conventional, improved and artificial intelligent methods. While, GMPPTs include soft computing and hybrid MPPT methods. This group of MPPTs can extract the GMPP under PSCs.

for tracking MPP at partial shading must be used the soft computing and hybrid MPPT methods such as

Particle Swarm Optimization (PSO)

- Cuckoo Search (CS)

- Ant Colony Optimization (ACO)

- Artificial Bee Colony (ABC)

- Simulated Annealing

- Genetic Algorithm (GA)

Thanks all

You can use PSO algorithm ( Particle Swarm Optimization )

Dear Adham,

Siham Alkhashief worked on the attached file.

Using PSO to find GMPP under partial shading, I hope this file helps you.
