CONCLUSIONS
This simulation investigates the effect of series compensation on the optimal location of
a shunt FACTS controller to get the highest possible benefit of maximum power transfer and
system stability. Various results were found for an actual line model of a series compensated
345 kV, 450 km line. It has been found that the optimal location of the shunt FACTS controller
is not fixed as reported by many researchers in the case of uncompensated lines but it changes
with the change in degree of series compensation.
The deviation in the optimal location of the shunt FACTS controller from the center point
of line depends upon the degree of series compensation and it increases almost linearly from the
center point of the transmission line towards the generator side as the degree of series
compensation (%S) is increased. Both the power transfer capability and stability of the system
can be improved much more if the shunt FACTS controller is placed at the
new optimal location instead of at the mid-point of the line
