Abstract
This study suggests a new simplified firefly algorithm (SFA) for maximum power point tracking (MPPT) of the solar system under conditions of partial shadowing. The disregarded and coefficients are present in the simplified firefly method, which is different from the regular firefly algorithm. The updated β coefficient for each iteration step is the second new feature, which helps to accelerate convergence. This approach is suggested to find the best PV system MPPT solution for three different shaded circumstances. The proposed method produced results with the highest possible power and efficiency. The ripple performed better than the conventional FA under steady-state conditions. The suggested algorithm’s key advantages over the conventional firefly algorithm are its simplicity, quicker convergence, and accuracy.
