Voltage profile and short circuit analysis in distribution systems with DG

The use of distributed generation (DG) within distribution systems has increased for the last two decades due to institutional requirements and technical advances. This study presents the impact of DG in different types of distribution systems in terms of voltage profile and short circuit analysis. Test systems representing three types of distribution systems (radial, loop and network) are simulated using the simulation tool of Powerfactory-DigSilent while changing the location and penetration level of DG in the system. The results are useful in better understanding the system impact of DG.
