Power system stabilizers (PSSs) must be capable of providing appropriate stabilization signals over a broad range of operating conditions and disturbances. The main idea of this paper is changing a classic PSS (CPSS) to an adaptive PSS using genetic algorithm. This new genetic algorithm based on adaptive PSS (GAPSS) improves power system damping, considerably. The controller design issue is for...

The static voltage stability and the dynamic voltage stability are integrated. To consider a shunt compensator and/or a more general load which is dependent on voltage, a modified criterion for the static voltage stability is developed and the system is controlled to satisfy this static Stability criterion. For an accurate analysis of the dynamic voltage stability, the system model includes exc...

This paper presents a robust Takagi-Sugeno Fuzzy Parallel Distribution Compensation (TSFPDC) based Power System Stabilizer (PSS) for damping power system low frequency oscillations. The main motivation of using this controller is minimizing the efforts of load disturbances and achieves the desired level of robust performance in the presence of modeling uncertainties. The effectiveness of the pr...

Applying multi-objective particle swarm optimization (MOPSO) algorithm to multi-objective design of multimachine power system stabilizers (PSSs) is presented in this paper. The proposed approach is based on MOPSO algorithm to search for optimal parameter settings of PSS for a wide range of operating conditions. Moreover, a fuzzy set theory is developed to extract the best compromise solution. T...

In this paper, damping power system oscillations is presented using the Elitist differential search algorithm (Elitist-DSA) in a multi-machine system. The tuning of power system stabilizers (PSSs) are presumed as the complex optimization problem for the security of power system. The linearized model of power system is transformed into a multimodal objective function and proposed algorithm is ap...

This paper presents an approach for designing Unified Power Flow Controller (UPFC) using Bacterial Foraging Algorithm (BFA) for damping low frequency oscillations in a power system. The problem of UPFC-based damping controller is formulated as an optimization problem according to the eigen value-based objective function comprising the damping factor, and the damping ratio of the un-damped elect...

Abstract: Artificial neural network (ANN) control of static compensator (STATCOM) to improve the damping of power systems is presented. The proposed control strategy is applied on a STATCOM attached to a single machine-infinite bus (SMIB) and a multi-machine power systems that include a superconducting generator (SCG). The proposed control method, ANN-STATCOM is designed based on proportional i...

With deregulation and growth of the power industry, many power system elements such as generators, transmission lines, are driven to operate near their maximum capacity, especially those serving heavy load centres. Wide Area Controllers (WACs) using wide area or global signals can provide remote auxiliary control signals to local controllers such as automatic voltage regulators, power system st...
