Abstract
FACTS devices employ high speed, and high
power semi-conductor technologies to help better regulate the
power systems. To improve the damping of oscillations in power
systems, supplementary control laws can be applied to the
existing FACTS devices. These supplementary actions are
referred to as power oscillation damping (POD) control. In this
paper, the POD controllers are designed using the frequency
response and residue methods. The small signal stability of power
systems as affected by TCSC devices and PODs are evaluated
and compared with the base power system where no FACTS
devices are included. Both modal analysis and time domain
simulations are presented to show the impact of the designed
PODs on damping the electromechanical oscillations in power
systems. Several examples are given to show the impact of POD
input signals on the design and system response. The results show
the capability of well designed FACTS-POD in improving the
stability of power systems. In addition, the design is successfully
implemented using the considered methods.
