Abstract
: Maximum power point (MPP) tracking (MPPT) techniques are widely used in photovoltaic (PV) systems to build PV array generate peak power which depends on solar irradiation. In this paper, an improved dP P&O MPPT algorithm is developed based on solar irradiation modeling. This algorithm aims to overcome the confusion in the direction of tracking during rapidly changing solar irradiance using half sine wave modeling of solar irradiation. The proposed algorithm gives fast tracking compared to existing dP P&O method. Operation point of the photovoltaic system is controlled via a boost type DC–DC converter. The complete system is modeled and simulated in the MATLAB using SIMULINK. The proposed MPPT and existing dP P&O MPPT algorithms are simulated and the performance comparison is made. Simulation result shows that the proposed algorithm is faster than the dP P&O algorithm.
