Abstract: To address the issue that it is difficult to complete islanding detection in multi-inverter systems, firstly the application features of three current islanding detection methods were studied, and the limitations of these methods for multi-inverter systems were noted. Then the advantages of both the remote method and the local active method were integrated, and a novel hybrid islanding detection method was proposed, which was much more suitable for multi-inverter systems. It could decrease the non-detection zone（NDZ）, shorten detection time, and reduce the impact on power quality. At last, several experiments were operated to compare the differences of the single-inverter island and the multi-inverter island, and to show the superiority of the hybrid islanding detection scheme on shortening detection time and improving power quality.
