摘要：

The output power of PV system can drastically decrease when photovoltaic modules under partially shaded condition. Therefore, partially shaded condition is a big issue to proper tracking maximum power point in photovoltaic systems. This paper proposes a new simple method which can track the global maximum power point under this condition. The proposed method is obtained by combining the incremental conductance algorithm and the sweeping p-v curve in the predetermined interval processing. The proposed method is implemented on a single phase grid-connected PV system, and is realized by adjusting the injected current into the grid. The model of proposed system is generated in MATIAB/Simulink. Moreover, an experimental setup is developed to confirm the effectiveness of the proposed system. The obtained simulation and experimental results show that the proposed algorithm can track accurately the global maximum power point of the PV system under uniform insulation and PSC.
