Active-Module을 이용한 태양광 발전시스템의 고성능 제어

This paper proposes the active module considering shadow influence of photovoltaic system. The voltage and current between PV modules become unbalance when shadow occurs to PV module. 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.
