Globally, the importance of power
interconnections is growing due to the possibility of power
exchange, Thus, the effective solution of bulk power
transmission over large distances is achievable with High
Voltage Alternating Current (HVAC) which has losses along the
transmission line. High Voltage Direct Current (HVDC) uses
converters to transform AC power into DC, resulting in
superior active and reactive power compensation and reduced
losses. The Flexible AC Transmission System (FACTS)
combines shunt and series convectors for improved voltage
control and power stability, and it enables the transmission of
large amounts of electricity over long distances with lower losses
than a conventional system. This study implements a load flow
model between three substations with bulk power coupled by
long-distance transmission lines to compare and conclude which
technology is best for transferring bulk power over long
distances to offer secure and sustainable electricity.
