This paper presents an investigation into the optimization of power system stabilizer (PSS) parameters using multi-power flow conditions. A simple objective function takes into account all the critical operating conditions. The steepest descent optimization method based on eigenvalue sensitivity is used for the minimization of the objective function ...

Stability Improvement of Wind Power Integrated System Using PSS and SVC
2013 Third International Conference on Intelligent System Design and Engineering Applications, 2013When a large amount of wind power being integrated into power system, will make system stability deterioration. At present these methods for improving stability are not very economical. This paper is aimed at solving the stability problem of multi-machine wind power integrated system, therefore power system stabilizer (PSS) are installed for ...

Enhancement of Power System Stability employing cat swarm optimization based PSS
2015 International Conference on Electrical, Electronics, Signals, Communication and Optimization (EESCO), 2015Low frequency oscillations are observed when large power systems are interconnected by relatively weak tie-lines. Power System Stabilizers (PSS) are incorporated in the excitation system of the generators to enhance damping of these low frequency oscillations.

A new conception for constructing and tuning power system stabilizers (PSS)
2003 IEEE Bologna Power Tech Conference Proceedings,, 2004This paper describes a PSS structure aided to handle the oscillations caused by the network frequency and/or network voltage deviation. In most cases, especially if the power plants investigated are on the boundary of a large system or the network is relatively weak, the impacts of the frequency oscillations in steady state - (/spl Delta/f/sub N ...

Power system stability enhancement through optimal design of PSS employing PSO
2017 4th International Conference on Advances in Electrical Engineering (ICAEE), 2017Interconnected power systems are critically vulnerable to instability due to the disturbances in any one portion of the system. Even low-frequency oscillations and small disturbances may lead to an outage of the system. Properly tuned Power System Stabilizer (PSS) is an effective tool for the suppression of these oscillations.

Stability Enhancement in Multi-Machine Power Systems by Fuzzy-based Coordinated AVR-PSS
International Journal of Energy Optimization and Engineering, 2015This paper presents performance of intelligent fuzzy-based coordinated control for Automatic Voltage Regulator (AVR) and Power System Stabilizer (PSS), to prevent losing synchronism after major sudden faults and to achieve appropriate post-fault voltage level in multi-machine power systems.

Analysis and simulation of PID-PSS design for power system stability improvement
2016 13th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2016Power system dynamic performance is improved by the damping of system oscillations. Power system stabilizers are added to excitation systems to enhance the damping during low frequency oscillations. In this paper, the structure of a power system stabilizer based on PID controller for system stability enhancement is presented.

A genetic algorithm PSS and AVR controller for electrical power system stability
2009 6th International Multi-Conference on Systems, Signals and Devices, 2009In this paper genetic algorithm (GA) is applied in order to design a PSS/AVR controllers with the goal of improving both transient stability and voltage regulation of power system under a symmetrical three-phase short circuit fault. A comparison based on simulation is then performed between the proposed approach and the classical controllers (manual ...

Power system stability enhancement by designing optimal PSS employing backtracking search algorithm
2017 6th International Conference on Clean Electrical Power (ICCEP), 2017Interconnected power systems are critically vulnerable to instability due to the disturbances in any one portion of the system. Even low-frequency oscillations and small disturbances may lead to an outage of the system. Properly tuned Power System Stabilizer (PSS) is an effective tool for the suppression of these oscillations.
