Abstract

It is difficult to increase the capacity of
the transmission system by establishing new lines or switching to a new voltage
level to meet the rapidly rising electricity demand. Thus, there is an
increased need for power flow controllers that can increase the capacity of the
existing transmission line and control power flows in predetermined
transmission corridors. For this reason, in recent years a new class of controllers
has emerged called Flexible AC Transmission System (FACTS). It is very
important to investigate the advantages of FACTS devices and to model these
devices so that power systems can be operated in steady state. In this study, a
comprehensive modeling of the most popular FACTS devices for power flow
operation was performed. Power flow studies were first performed using the
Newton Raphson method for an IEEE 5-bus power system without any FACTS devices.
Then, different FACTS controllers were added to the system to perform power
flow studies. As a result of the power flow studies performed, it was observed
that the FACTS controllers increased the capacity of the existing transmission
line and contributed to the voltage stability.
