Abstract
Flexible power point tracking (FPPT) terminology has recently emergedto support additional functionality for grid-connected systems. Despite having a well-developed operation under uniform irradiance conditions, the FPPT algorithm's operation under partial shading conditions(PSC) reveals substantial challenges. The presented article introduces a global FPPT (GFPPT) algorithm that can operate under the PSC with a fast-trackingspeed. The proposed GFPPT algorithm employs the conventional search-skip-judge global maximum power point trackingmethod and the essential strategic scheme. The method conducts on the left side of the power-voltage curve to avoid the less robust nature ofthe right-sideoperation. Simulation and experimental tests are employed to validate the adequacy of the proposed approach. The simulation and experimental study adopted an indirect control approach using a proportional-integral controller and a buck-boost dc-dc converter. The uniform irradiance condition and PSC patterns with various peaks are chosen, and the presented GFPPT method is applied underdistinct criteria. The proposed method's effectiveness has been adequately validated based on the simulation and experimental outcomes.
