Stability
Transient stabilityis the ability of the
power system to maintain synchronism
when subjected to a severe transient
disturbance.

Conclusion
UPFC provide additional damping
coefficient to the power system under
transient condition.
Therefore, it has been decided that the
UPFC can perform as a stabilizer.
