In this paper, damping of interarea oscillations using simultaneous coordination of static Var compensator (SVC) and power system stabilizer (PSS) is considered. To be effective in damping of oscillations, the best-input signal of power oscillation damper (POD) associated with SVC is selected using Hankel singular values (HSVs), and right-hand plane zeros (RHP-zeros). The 4-machine-2 area standard test system, under different systemconfigurations and loading conditions, is employed to illustrate the performance and robustness of the proposed controller. Eigenvalue analysis and nonlinear time domain simulationresults demonstrate the effectiveness of the proposed technique to mitigate interarea oscillations under various operating conditions
