Abstract
Extracting available maximum power is an important component of solar photovoltaic system which can be achieved by an efficient maximum power point tracking algorithm. Up to date review of related works summarized available MPPT algorithms as classical and modern optimization techniques. Among classical algorithms the incremental conductance (InCond) and perturb & observe (P&O) based tracking algorithms with duty ratio control are widely used due to relatively accurate MPP tracking capability and less implementation complexity under uniform radiation. However; steady-state oscillation, wrong perturbation direction for rapid climate change and failure to track the global peak under partial shade/mismatching operating conditions of the photovoltaic system are some of the limitations of these algorithms. Thus, in this work, a succinct review, formulations and evaluations of widely used classical techniques along with a proposed classical improved perturb and observe (IPO) to improve drawbacks of steady state oscillation has been done. The performance evaluation results of widely used classical perturbation based algorithms (InCond, P&O, IPO) using MATLAB/Simulink revealed improved performances of the improved perturbation based algorithm over the widely used classical (InCond, P&O) algorithms in reducing steady-state oscillations of step-change in irradiance without any partial shading condition of the photovoltaic (PV) of the PV system.
