A Novel MPPT Tactic for PV Systems with Fast-Converging Speed and Zero Oscillation

This paper proposes a novel algorithm for maximum power point tracking (MPPT) in photovoltaic panel sourced boost converter. The novel MPPT tactic has a high convergence speed and zero oscillation around the MPP under steady state operation, and high tracking speed in response to rapid changing of irradiance. Furthermore, it improves the tracking accuracy, without increase the implementation complexity. The proposed technique has been simulated in Matlab/Simulink environment and compared with some other MPPT techniques, such as Perturbed and observed (P & O), Increment of Conductance (INC) and fuzzy logic (FLC).
