I-V Curve Tracer Based Intermittent Maximum Power Point Tracking for Photovoltaic System

Conventional maximum power point tracking (MPPT) methods exist in various ways and are being actively studied, but there are problems to be improved. This paper proposes an I-V curve tracer based intermittent MPPT control system that can extract the characteristics of PV module & array. Therefore, through the proposed system using the I-V Curve Tracer (IVCT) in this paper, we suggest the possibility of ultimately lowering the LCOE (Levelized Cost of Energy) by increasing the efficiency and lowering the cost from a systemic point of view. Simulation and experimental results of the proposed system show an accuracy of at least about 98 %.
