This paper proposes the combination of
firefly and P&O algorithm to get both of its benefit.
Simplified firefly algorithm used for escaping partial
shading multi peaks condition due to Partial Shading
Condition (PSC). When it goes yet to converge, the
algorithm used is switchedto faster modified P&O
This proposed algorithm is to obtain the optimal
solution for Maximum Power-Point Tracking (MPPT) of
Photovoltaic (PV) system under three shaded conditions.
The simulation results are compared with traditional
Perturbation and Observation (P&O) and Simplified
Firefly Algorithm (SFA) to verify the proposed method
performance. The main advantage of proposed algorithm
is faster convergence and tracking speed compared to its
previous method that is Simplified Firefly Algorithm
