In this paper, a control technique based on simultaneous regulation of all control coefficients for Unified Power Flow Controller (UPFC) and Power System Stabilizer (PSS) is proposed. Non-Dominated Sorting Particle Swarm Optimization (NSPSO) has been used for parameter optimization. Studies in time and frequency domains for single machine infinite bus power system (SMIB) in different operationa...

In this paper, two new power system stabiliser (PSS) designs are proposed. The first one is based on a combined particle swarm optimisation (PSO) with linear matrix inequality (LMI) optimisation thereby improving previous existing results. The property of PSO of not sticking into a local minimum is used to eliminate the conservativeness of the design result utilising the static output feedback ...

This paper presents the settings of automatic voltage regulator (AVR) and power system stabilizer (PSS) on a single machine infinite bus (SMIB) to improve the dynamic stability of the power system. This setting is done by determining the fitness function of AVR (KA) and PSS (KPSS) gain using Particle Swarm Optimization (PSO) algorithm. The main purpose of this setting is to minimize the oscilla...

Secure operation of power systems is receiving a renewed interest due to considerable structural changes and greater uncertainties. Thus, motivated by implementation of wide-area measurement systems in power systems worldwide, recent research work is being devoted to the development of enhanced tools for fast security assessment within reduced time frames. The work presented in this paper intro...

Synergism of two intelligent control techniques namely Artificial Neural Network and Genetic Algorithm has been presented in this paper. The technique has been implemented to design power system stabilizer. The power system stabilizer designed with help of neural network while the network is optimized by the genetics algorithm. The power system stabilizer has been used to generate the appropria...

This paper presents an optimal design of a Static Var Compensator (SVC) for damping improvement of a Single Machine Infinite Bus (SMIB) system.

In deregulated power systems, competition could push the system near its security limit. The issue of power system stability is becoming more crucial. The excitation and governing controls of generator play an important role in improving the dynamic and transient stability of power system. Typically the excitation control and governing control are designed independently. In this paper, we prese...

A Power System consists of the generating machines and transmission network in which the generating machine includes turbine, alternator and excitation system. Every synchronous generator has rotating rotor which has some inertia that depends upon the stored rotating energy in the system. There are various types of disturbances which are occurring on the power system. A stable power system shou...
