Abstract

This paper presents two analytical frameworks to study the fault current contribution from inverter based distributed generation (IB-DGs) in transient and steady state conditions. The developed models can be used to analyze the fault response of IB-DGs in active distribution networks. The steady state analysis of fault current contribution from IB-DGs is calculated using the forward-backward sweep method, whereas the transient model for the IB-DGs is developed using the IB-DG differential equations. The results of the both models are validated by PSCAD simulations.
