PV Sistemlerde Kullanılan Maksimum Güç Noktası İzleme Tekniklerinin İncelenmesi ve Değerlendirilmesi

Abstract

The issue of improving the efficiency and effectiveness of PV systems remains a concern of researchers and manufacturers, who aim to make these systems cost-effective, thereby encouraging their wider adoption. To achieve this aim, increasing the PV generation system's efficiency by using the maximum power point tracking (MPPT) system has been proposed. Increasing the generated energy from the PV system is considered a key aspect in increasing efficiency, as it will increase incomes. Consequently, the cost of the generated energy is reduced, leading to it approaching the cost of energy produced from conventional systems based on fossil fuel. This review paper discusses conventional MPPT techniques designed to extract the maximum available power from PV panels operating under uniform environmental conditions. After that, the reason why these techniques fail to perform adequately under partial shading conditions is highlighted. Following this, modern MPPT techniques explicitly designed to operate under non-uniform and partial shading conditions are analysed.
