The improved characteristics of the Stand-alone PV system

소규모 독립형 태양광 발전 시스템의 특성 개선

The MPPT methods is used to get the maximum energy from the limited size of a photovoltaic array. This study deals with the suitable MPPT method of solar lighting lamp and the improved charge and discharge characteristics. So we proposed the control algorithm for stand-alone photovoltaic array(SPVS). The result of experiment is presented the improved charge characteristics and the charge and discharge times reduction, the depth of discharge control. so, the system stabilization goes up. It is possible economical effect to apply for solar lighting lamp used photovoltaic array
