Study on Single-phase Photovoltaic Power Generation System with Power Decoupling and Generation Control Functions

In photovoltaic (PV) power generation systems, extant studies which focused on either a generation control circuit (GCC) to prevent power reduction caused by a partial shadow or an active power decoupling method (APD) to reduce power pulsation with twice the utility frequency have been reported from various authors. However, to the best of the authors' knowledge, only a few studies examine PV inverters in which both GCC and APD functions are installed. In this paper, a utility interactive PV inverter equipped with GCC and APD functions is proposed.
