With the interconnection of distributed generator, the distributed network loses its radial nature, the fault current changes in magnitude, direction and distribution. And it causes serious influence on the correct operation of protection of distributed network. It needs to limit penetration level of distributed generator to ensure the correct isolation and clearing of fault. This paper proposed a method to calculate the allowed penetration level of distributed generator.
