I.INTRODUCTION
WORLDWIDE transmission systems are undergoing
continuous change stemming mainly from the strong
increase in power transfers between systems,opening of the
market for delivery of cheaper energy to customers,and economic
and ecological constraints which delay the building
of new transmission facilities.Since the construction of new
transmission lines cannot keep pace with the growing power
plant capacity and energy demand,operators are looking at
ways to utilize the existing power lines more efficiently,operating
the grid in ways not originally envisioned.The need
for more efficient power systems management,and the fast
development of power electronics based on new and powerful
semiconductor devices,have given rise to innovative technologies,
such as voltage source converters (VSC)-based FACTS
controllers [1].
Among the VSC-based controllers commissioned and installed
in several transmission syste
