This paper proposes a residue factor method to obtain the optimal location of the Thyristor Controlled Series Capacitor (TCSC) device to damp out the inter-area mode of oscillations. The residue method is base on the facts that it is the product of the mode’s Observability and controllability index of TCSC controllers to the critical mode. The placements of TCSC controllers have been obtained for the base case and for the dynamic critical contingences. Eigen value analyses are used to assess the most appropriate input signals (stabilizing signal) for supplementary damping control of TCSC. The Right-Half Plane zeros (RHP-zeros) and Hankel Singular Value (HSV) is used as tools to select the most receptive signal to a mode of the Interarea oscillation. The effectiveness of the proposed method of placement is demonstrated on practical network of 25 bus south Malaysian Power system.
