Summary:In this paper impact assessment of insertion of Distributed Generation units in radial distribution network is studied. Electrical equivalent network of 3 bus systems is used to study power flow during fault time. Different protection problems are created by DG in a system coordinated for radial power flow. A new methodology is proposed which minimises influence of DG in the performance of protection coordination. In this adaptive scheme different protection coordination settings are provided for each configuration for different size DG on each location. A part of IEEE 13 nodes Radial Distribution Test Feeder, is used to study this proposed methodology.
