“…Note that for PSS design, the ideal phase compensation (IPC)-enables departure angle of EM mode for the compensated system equal to 180 -for the EM mode of case A is higher than cases C and E across all operating conditions. However, phase lead overcompensation is often preferred due to its damping performance-ignoring the gain modification of lead compensation [17]. Its associated risks in PSS tuning are 1) negative synchronizing torque component and 2) faster instability of susceptible modes, leading to a much reduced gain margin.…”

In this paper, a technique for designing fixed parameter decentralized power system stabilizers (PSSs) for interconnected power systems is proposed. In the proposed method, local information available at each machine in the multimachine environment, is used to tune parameters of PSS. Conventional design techniques such as P-Vr frequency response approaches, and the method of residues are based on complete system information, wherein phase angles of residues are consistent with the P-Vr phase response and can be used with confidence for design purposes. It is shown that magnitude and phase information of the proposed GEP TF agrees closely with that of P-Vr TF and yields a robust stabilizer. Nonlinear simulation and eigenvalue analysis show the efficacy of the proposed stabilizer to damp out the interarea and local modes of oscillations effectively over a wide range of operating conditions. Superiority of the proposed approach over the conventional approaches is demonstrated with simulation studies on two widely used multimachine systems.Index Terms-Eigenvalue, multimachine systems, power system dynamic stability, power system stabilizer, small signal stability.
