Practical application considerations for power system stabilizer (PSS) controls
199 IEEE Power Engineering Society Summer Meeting. Conference Proceedings (Cat. No.99CH36364), 2003The basic function of the PSS is to apply a signal to the excitation system, creating electrical torques that damp out power oscillations. There is a significant body of literature about the design, tuning and performance of PSS controls. In some cases this previous work has not fully considered some important practical aspects that can affect the way ...

Tuning of power system stabilizer PSS using genetic algorithms
2014 IEEE International Autumn Meeting on Power, Electronics and Computing (ROPEC), 2014The present work proposes a methodology to obtain setting parameters of a power system stabilizer (PSS), through the implementation of search technique based on genetic algorithms (GA). To adjust the PSS using GA, the programming and dynamic analysis using Matlab / Simulink is performed, which includes the synchronous machine, excitation system and PSS,

Power system stabilizers (PSSs) are added to excitation system to enhance the damping of low frequency oscillations. In this paper, the design of PSS for multimachine power system (MMPS) using output feedback sliding mode control is proposed. The nonlinear model of a multimachine power system is linearized at various operating points and the linearized

Power-system stabilizer (PSS) design by probabilistic sensitivity indexes (PSIs)
IEEE Transactions on Power Systems, 2002A probabilistic power system stabilizer (PSS) design considering multioperating conditions is proposed in this paper. Under the assumption of normal distribution, the conventional eigenvalue sensitivity analysis is extended to a probabilistic environment by describing the statistical nature of eigenvalues as expectations and variances.

PSS-LL based power system stability enhancement using IPSO approach
2013 IEEE 7th International Power Engineering and Optimization Conference (PEOCO), 2013This paper introduced a new swarm based optimization technique for tuning Power System Stabilizer (PSS) that attached to a synchronous generator in a single machine infinite bus (SMIB) system. PSS which is installed with Lead-Lag (LL) controller is introduced to elevate the damping capability of the generator in the low frequency mode. For tuning three

Compatible Decentralized Control of AVR and PSS for Improving Power System Stability
IEEE Systems Journal, 2021Automatic voltage regulator (AVR) and power system stabilizer (PSS) as the most common excitation controllers have implemented incompatible decentralized control (IDC) due to the asynchronous sampling by the voltage/current transformer. However, IDC results in the incompatibility of decentralized AVR and PSS in regulating generator dynamics, which ...

For solving the dynamic instability problem of Yunnan Province Power System (YNPS) and the South China Interconnected Power System (SCIPS), Lubuge hydropower plant was chosen to install a power system stabilizer (PSS). The philosophy to set the parameters of PSS is to provide positive damping within the frequency of 0.4/spl sim/1.6 HZ specially 0.4/spl
