Power system stabilizers (PSSs) are used to enhance the damping during low frequency oscillations. Artificial intelligence techniques provide one alternative for stability enhancement and speed deviation (Δw). In this paper we have applied Fuzzy based and Support Vector Machine (SVM) based approach to PSS for Single Machine Infinite Bus (SMIB) System .The proposed method using SVM techniques ac...

This paper presents an Artificial Bee Colony (ABC) algorithm for optimal tuning of the Power System Stabilizer (PSS) in a Single-Machine InfiniteBus (SMIB) power system. The design problem of robustly tuning PSS parameters is formulated as an optimization problem according to the time domainbased objective function which is solved by the ABC technique that has strong ability to find the most op...

In this paper, a Problem of simultaneous and coordinated tuning of the PID type Power System Stabilizer (PSS) and Automatic Voltage Regulators (AVR) gains in a Single-Machine connected to InfiniteBus (SMIB) power system is invastigated. The problem of robustly stabilizer parameters and AVR gain tunning is formulated as a nonlinear optimization problem according to the time domain-based objectiv...

The design of a conventional power system stabilizer (PSS) based on linearized model cannot guarantee its performance in practical operating, so some intelligent techniques have been used. However, the parameters cannot update online in most of these mehods, thus the performance cannot be further improved. This paper adopts the design method of adaptive neural-fuzzy based power system stabilize...

Particle Swarm Optimization with Time Varying Acceleration Coefficients (PSO-TVAC) is used to optimize Power System Stabilizer (PSS) parameters for a multi objective power system in this paper. In the proposed Syndicate tuning technique, two performances indicates as ITAE and FD are computed for the stability and performance at each of the given set of operating conditions of the system simulta...

Power system stability enhancement via robust coordinated design of a power system stabilizer (PSS) and a static VAR compensator (SVC)-based stabilizer is thoroughly investigated in this paper. The coordinated design problem of robust excitation and SVC-based controllers over a wide range of loading conditions and system configurations is formulated as an optimization problem with an eigenvalue...

This paper introduces the working principle and the mathematical model of additional power system excitation control-Power System Stabilizer (PSS). Through established a typical single machine-infinite bus power system simulation model, we simulate the synchronous generator’s transient operational characteristics following a severe disturbance. The simulation results show that the PSS can not o...
