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.

“…Auxiliary controller called power system stabilizer (PSS) provides additional damping to the synchronous generator rotor oscillations by modulating the generator excitation. PSS design has been well studied in the literature over the past few decades [1]- [11], [17], [18], [22].…”

“…The main interest in this paper is on power system applications where the system poles are all singles. Although power system models with repeated poles can arise, such as in symmetrical multigenerator plants [16] the practice has shown that these eventual cases can be fairly easily managed by dynamics and control engineers. Therefore a system TF can be expanded into partial single pole fractions as…”

“…In the last decade, the research of neural networks [1]- [3] have become a hot topic, at the same time, researchers have been investigated the control problems of various systems, for example, physical systems [4], Takagi-Sugeno fuzzy systems [5], [6], nonlinear systems [7], multi-agent systems [8], [9], and networked systems [10]- [12]. Networked control systems (NCSs) have been well developed in many fields, such as telemedicine [13], [14], automatic current regulation [15], [16], industrial control [17]- [19]. As is known to all, the stability of NCSs have been studied extensively in feedback control systems [20]- [27].…”

In this paper, the performance of the single-input multiple-output (SIMO) networked timedelay systems is investigated. The performance is related to the internal factors, communication parameters and reference signals, and the boundary is related to the adjustment factors. Some new results are derived according to the inner-outer factorization and Cauchy's Theorem of two degrees-of-freedom controller. The results show that the performance is in connection with the inner factor (unstable poles, non-minimum phase zeros of the system). It is also demonstrated that the modified performance will be badly degraded by feedback channel quantization and adjustment factor constraints, and encoding-decoding is beneficial to the modified performance. INDEX TERMS Networked time-delay systems, modified performance, inner-outer factorization, SIMO.
