Power System around the world are transitioning into the phase of accommodating large scale and small scale Distributed Generation (DG). To harvest the benefits of DG, determining the most influential generator and associated network-wide impacts are crucial. This paper proposes a novel visualisation method to determine the sphere of influence of DG in the network using line current flows. The proposed visualisation technique trades off tedious calculations and provides information-rich overview of a network and enables distribution network service providers to make judicious decisions in order to determine sphere of influence of DG. The visualisation concept is tested on a 33 bus distribution network and implemented using DigSILENT Power Factory, Python and Matlab.
