태양광발전의 저출력으로 인한 인버터 트립 방지를 위한 출력전압 제어 시스템

In this paper, we suggest output voltage control system for prevention of inverter trip due to low voltage output of PV. Output of PV system are dependent on insolation and temperature of PV cell. So inverter of PV system trip out that radiation and temperature are changed. Inverter trip decreases power quality and efficiency. Output voltage control system to prevent inverter trip can improve power quality and efficiency of PV system.
