PV Sistemlerde Kullanılan Maksimum Güç Noktası İzleme Tekniklerinin İncelenmesi ve Değerlendirilmesi

Abstract

The issue of improving the efficiency and effectiveness of PV (Photovoltaic) systems remains a concern for researchers and manufacturers who aim to make these systems cost-effective, thereby encouraging their wider adoption. To achieve this goal, increasing the efficiency of the PV generation system by implementing the Maximum Power Point Tracking (MPPT) system has been proposed. Enhancing the energy output from the PV system is considered a crucial aspect of improving efficiency, as it will lead to increased revenue. Consequently, the cost of the generated energy is reduced, approaching that of energy produced by conventional systems based on fossil fuels. This review paper discusses conventional MPPT techniques designed to extract the maximum available power from PV panels operating under uniform environmental conditions. Subsequently, it highlights why these techniques often fail to perform adequately under partial shading conditions. Following this, modern MPPT techniques explicitly designed to operate under non-uniform and partial shading conditions are analyzed.
