Static Var Compensations (SVC) controller is used to improve voltage and damp oscillations in power system. It has been proved that the centre 01- midpoint of a transmission line is the optimal location for shunt FACTS devices or reactive power support and the proof is based on the simplified line model. However, it is difficult to find optimal placement of SVC on large-scale power system. In addition the effectiveness of SVC controller, particularly to damp oscillations depends on its location very much in the power system. This paper presents an energetic approach based on controllability Gramian for optimal placement of SVC to damp the oscillations. The effectiveness of the proposed method has been tested on New England 39-bus system by using PSS/E and Matlab software.
