Abstract—Distributed generation (DG) are connected to the
grid via a power electronic interface that regulates the amount
of power injection to the grid by regulating point of coupling
(PCC) voltage or converter control circuit. The PCC parameters
are used to decide the operational mode of DG. The power
electronic interface badly affected by at current and voltage in
the event of a fault. The focus of this paper is at describing how
solid-state fault current limiter (SSFCL) may be considered for
voltage sag mitigation and fault current control of a parallel
distribution feeder connected to a 100 KW photovoltaic system.
This 100 KW photovoltaic system is connected to above said
feeder with a 100 KVA transformer. To avoid any damage to
power electronic interface, it is required to determine
prospective fault current and voltage sag mitigation at point of
coupling (PCC). The performance of SSFCL is assessed with
prospective fault current, voltage sag mitigation and
suppression of fault current for unsymmetrical /symmetrical
faults on a parallel distribution feeder connected to photovoltaic
system.
Index Terms—Voltage sag mitigation, solid-state fault
current limiter, prospective fault current, grid connected
photovoltaic.
