To estimate the fault current profile on such a feeder, the paper proposes a new method which extends the capability of conventional short-circuit analysis method. The paper also shows that this time-varying fault current profile makes it also more difficult to estimate the time it will take for an overcurrent relay/device to interrupt such a fault current. The paper proposes a method for estimation of this operating time also. Performance of the proposed methods has been assessed by simulations on a sample distribution feeder.}, number={3}, journal={IEEE TRANSACTIONS ON POWER SYSTEMS}, author={Hooshyar, Hossein and Baran, Mesut E.}, year={2013}, month={Aug}, pages={2890–2896} }

PV systems are smaller scale resources and therefore they have different impact on a distribution circuit than larger scale resources. The paper indeed considers a typical residential feeder and investigates PV system impacts on the system at different penetration levels. Simulations on this system show that the even the high penetration level PV systems can be accommodated as the impact on the system will not be severe.}, booktitle={2011 ieee power and energy society general meeting}, author={Baran, Mesut and Hooshyar, H. and Shen, Z. and Gajda, J. and Huq, K.
