Randomized trial demonstrates enhanced global MPPT accuracy in photovoltaic systems under partial shading, suggesting improved energy extraction methods.
Key Points
The aim is to develop and validate the FTM-CHHO algorithm for efficiently maximizing power output in photovoltaic systems under partial shading conditions.
Developed a novel FTM-CHHO algorithm integrating fractional-order memory and chaotic maps.
Conducted simulations and hardware experiments using a SEPIC converter to validate performance.
Compared FTM-CHHO with perturb and observe (P8O) and standard horse herd optimization (HHO).
FTM-CHHO achieved 99.52% to 100% tracking accuracy with convergence times of 0.32 to 0.62 seconds in simulations.
Under real-world conditions, it maintained 95.54% to 98.26% accuracy with convergence times within 10.1 seconds.
FTM-CHHO significantly outperformed both P8O and HHO.
