A Time-Domain Short Circuit Study for a VSC Based Battery Energy Storage System
Published via IEEE Xplore
Abstract
A phasor domain short circuit study for a battery energy storage system was performed per ANSI C37.010-2016. Results showed high short circuit asymmetrical currents. Two time-domain models were also built— simplified and detailed ——to compare the results with the phasor domain study. The results of both the simplified and the detailed...
