Submodule based MPPT with synchronous buck converter under dynamic partial shading conditions

In order to obtain more power from photovoltaic (PV) modules under mismatching operating conditions, the submodule-based MPPT technique is an important solution. this technique, since power-voltage (P-V) curve of a submodule cannot be multi-peaked, maximum point (MPP) tracking (MPPT) easily achieved through DC-DC converter connected each submodule. Since P-V in multi-peaked form, can obtained with simple algorithm. For reason, perturb & observe (P&O) algorithm chosen. study, behaviour synchronous buck (SBC) investigated for dynamic shading conditions. addition, and module-based were compared comparison was confirmed by simulation studies that performed better. context, carried out different According results, approach achieves greater efficiencies MPPT. some simulations, when used, operation at local MPP has been realized. such cases, advanced algorithms are needed. However, sufficient The only disadvantage high hardware cost. increase efficiency level tolerate
