摘要
This paper proposes the active module considering shadow influence of photovoltaic system. The PV system is consisted series-parallel connection of PV module. The voltage and current between PV modules become imbalance when shadow occurs to PV module. If shadow occurs to the series connection PV module, the output current is limited to current of shaded PV module. Also if shadow occurs to the parallel connection PV module, the output voltage is limited to voltage of shaded PV module. These problems are caused power loss. Therefore, this paper proposes the active module that is consisted fixed module and variable module. The active module can compensates the shadow influence by changing connection of a variable module when shadow is occurred to PV module. A validity of the active module proposed in this paper proves through comparing with performance of conventional PV module.
