摘要
Abstract
As the existing islanding detection method based on MPPT have non-detection zone, large power loss and other issues, an improved islanding detection method based on MPPT is proposed. This method is based on increasing the duty ratio D of boost circuit, reducing the output voltage and the output active power of the inverter. Influence of public point voltage when grid outage, beyond its over/under voltage protection threshold, thereby detecting the islanding state. In this paper, the active matching of local load and distributed PV system is fully considered, the non-detection zone is eliminated. This algorithm increases the disturbance period, thereby reducing the power loss and the impact on power quality. According to IEEE Std.929-2000, the results of simulation and experiment show that the proposed algorithm is correct and effective.关键词
