Abstract

Abstract: The PV generation system operates in maximum power of PV array by MPPT control of power conditioning system (PCS). However, there is a problem that maximum power of the PV array configuration greatly decreases by partial shadow. For this problem, the authors previously proposed the active PV array(APV) system which is able to extract total power of the maximum power of each PV panel with preset PV array voltage, equipping each panel with the buck-boost converter(Unit). This APV system is able to maintain the ideal P-V characteristics under all conditions. In this paper, the effect of this method is demonstrated by simulation and experiment. In this investigated condition, it is clarified that the generated power of the proposed APV system is 1.6 times, compared with the conventional PV array system.
