Power-system stability improvement by a static synchronous series compensator (SSSC)-based controller is studied in this paper. Conventionally, the lead-lag structure was used to modulate the injected voltage. But, in this paper, PID controller is also considered. The design problem of the proposed controller is formulated as an optimization problem and Differential Evolution Algorithm is used ...

when power systems are expanded and connected together with weak tie lines, the low-frequency oscillations are increased and the stability margin of the power system decreases. therefore, when designing the transmission system to be used, it is necessary to maintain the dynamic stability of the power system, and to make sure to have the most possible stability margin. sssc is a facts device con...

This paper proposes a new genetic based approach for optimal selection to damp power system oscillations by a Static Synchronous Series Compensator (SSSC) based controller. The design problem of the proposed controller is formulated as an optimization problem and modified Genetic Algorithm (MGA) is employed to search for the optimal controller parameters. The performances of the proposed contro...

A simple neuro-controlle r for a synchronous generator is presented in this paper. The controller performs the function of the terminal voltage control. By representing the proposed neuro-controller in s-domain, its parameters to ensure system stability can be obtained analytically. Results of simulation studies on a non-linear seventh order generator model with the neuro-controller using calcu...

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 ...
