Loss of Distributed Generation in Case of Fault in Distributing Net

This is the authors' abstract. We don't add key points for this paper.

This paper deals with the 22 kV distribution grids with higher penetration of distributed generation and the possibility of loss of this generation in case of fault. In the first part the reasons of distributed generation growth are shortly explained. For simulation of faults of different parts of distribution grid the model of such distribution grid with substantial amount of distributed generation was created. The second part contents the simulations of two-phase faults in two different power lines of model in order to evaluate and analyze the impact of these faults on distributed generation. The second part focuses on the impacts of short circuit occurred in different feeders of distribution grid on individual power sources and on the feeder with higher penetration of distributed generation.
