【 摘 要 】

Photovoltaic (PV) systems generate a significant amount of electrical energy used around the world. In accordence with high cost and low effienciency, solar panels and arrays should be operated at the maximum power point (MPP). Photovoltaic cells have variable current and voltage characteristics and MPP depends on solar irradiations and ambient temperature. Obtaining maximum power and reaching highest efficiency level in these panels is an important research topic [1], [ 2]. Maximum power poin tracking (MPPT) is developed to capture maximum power level in variable atmospherically conditions [3], [4]. In this study, the behaviour of varied incremental conductance (IC) MPPT algorithm implemented to PV modules. Larger-medium-small fixedstep sizes and variable step size were applied, analyzed under various conditions. In order to compare the step size impressions, all cases were simulated on MATLAB/Simulink platform.
