Since the idea of synchronizing two identical chaotic systems under different initial conditions was first introduced by Pecora and Carroll, the synchronization of chaotic systems has attracted much attention, and the synchronization of non-identical chaotic systems has also been investigated. Single-Machine Infinite-Bus (SMIB) power system has nonlinear behaviour. On account of avoiding undesi...

This article is devoted to investigating the evolution of probability density function for power system excited by fractional stochastic noise. First, single-machine-infinite-bus (SMIB) model Gaussian noise (FGN) established. Second, we derive Fokker–Planck–Kolmogorov (FPK) equation proposed and solve FPK using finite difference method. Finally, numerical results verify that addition FGN would ...

In this paper, simulation results using MATLAB / SIMULINK of conventional and fuzzy type both power system stabilizers are shown. The performance of the proposed model is tested and performed on Single Machine Infinite Bus System (SMIB). By using different K constant, the performance of SMIB system with proposed model has been analyzed under different system condition i.e. SMIB with excitation ...

Abstract: A controllable series device (CSD) is used to damp the transient oscillations in a power system. The power system studied here is the single machine infinite bus (SMIB) and the CSD used is a controllable series capacitor (CSC). Interconnection and damping assignment passivity-based control (IDA PBC) is used for controller synthesis. The SMIB system is described with two different type...

This paper investigates the mechanism analysis and the experimental validation of employing superconducting magnetic energy storage (SMES) to enhance power system stability. The models of the SMES device and the single-machine infinite-bus (SMIB) system with SMES are deduced. Based on the model of the SMIB system with SMES, the action mechanism of SMES on a generator is analyzed. The analysis t...

Recently, a novel hybrid power flow controller (HPFC) topology for FACTS was proposed. The key benefit of the new topology is that it fully utilizes existing equipment. The MATLAB/SIMULINK models of three different configurations of HPFC have been investigated for their different characteristics, by incorporating them in the SMIB system. In all the three cases, the steady state stable values of...

 Abstract—Many natural and manmade dynamical systems that are modeled as large nonlinear multi-oscillator systems like power systems are hard to analyze. For such systems, we propose a nonlinear modal decoupling (NMD) approach inversely constructing as many decoupled nonlinear oscillators as the system’s oscillation modes so that individual decoupled oscillators can be easily analyzed to infer...

The paper deals with analysis of loading conditions on damping torque coefficient and synchronizing coefficient in SMIB system and design of Delta-Omega type of damping controller for damping of power oscillations in the system. Effect of variation of loading on synchronizing torque and damping torque coefficients has been investigated in detail. A new design approach for optimizing the paramet...

This paper presents an alternate approach for designing power system stabilizers (PSS) based on variable structure control to enhance small signal stability of Single Machine Infinite-Bus Power System (SMIB). The state feedback gains and switching surface have been tuned using Global Optimization (multistart clustering GO) for an Eigen value based performance index. The robustness of the propos...

A Sliding Mode Controller (SMC) is adopted in this work with a Proportional Integral Derivative (PID) to employ instead of Power System Stabilizer (PSS). The major proposal is that the effective property of PID and high characteristics of SMC are combined to eliminate the chattering effect of SMC in order to generate best control signal to the excitation system. The robust design of SMC-PID has...
