The stability related issues may occur in a power system due to disturbances generating or loading conditions, especially the presence of distributed generation (DG) based on renewable energy resources (RERs). This paper proposes novel strategy for enhancement wind (WPGS) by using combination three devices, namely, stabilizer (PSS), resistive superconductor fault current limiter (R-SFCL) and st...

A systematic procedure for modeling, simulation and optimally tuning the parameters of a Static Synchronous Series Compensator (SSSC) controller in a multi-machine system, for power system stability enhancement is presented in this paper. For the simulation purpose, the model of multi-machine power system with SSSC controller is developed in MATLAB/SIMULINK using Sim Power System (SPS) blockset...

Power system stabilization is a major issue in the area of power systems research. The Conventional Power System Stabilizer (CPSS) parameters are tuned by using Genetic Algorithm to achieve proper damping over a wide range of operating conditions. The CPSS lack of robustness over wide range of operating conditions. In this paper type-2 Fuzzy Logic Power System Stabilizer (FLPSS) is presented to...

The voltage source converter (VSC) excitation system is a novel excitation system based on pulse-width modulation (PWM) voltage source converter, which is proposed as improved alternatives to the conventional thyristor excitation systems. This paper aims to provide theoretical confirmation of power system stability enhancement by the VSC excitation system. The reactive current injected to gener...

Abstract: Power system stabilizers (PSSs) are widely used for suppressing low frequency oscillations in practical power systems. However, according to the requirement of the “guide for setting test of power system stabilizer” of China, PSS gain is limited to no more than 1/3 of its critical gain. As a result, PSSs may not provide enough damping to the inter-area mode oscillations. Through analy...

Electromechanical oscillations in a power system often exhibit poor damping when the power transfer over a corridor is high relative to the transmission strength. Traditional approaches to aid the damping of power system oscillations include the use of Power System Stabilizers (PSS). Power system stabilizers are used to generate supplementary control signals for the excitation system in order t...

Here in this paper we proposed an improved technique to reduce the power quality problems in Long distance AC transmission system with fuzzy logic controller (FLC). Large power systems are often suffered from weakly damped swings between synchronous generators. This paper aims to enhance the transient stability of the power system with the use of Distributed Static Series Compensator (DSSC).The...
