This paper describes the current development of the new energy, analyzes the islanding detec- tion principle and makes reasoning verification. Comparing the traditional islanding detection algorithm and the improved active-voltage positive feedback islanding detection algorithm, this paper makes a quan- tified comparison through voltage-active response curves and sets feedback parameters through analysis and calculation. A simulation model of the distributed power generation device is built and then tested.
