Power System Stabilizer Design Based on a Particle Swarm Optimization Multiobjective Function Implemented Under Graphical Interface
Abstract: Power system
stability considered a necessary condition for normal functioning of an
electrical network. The role of regulation and control systems is to ensure
that stability by determining the essential elements that influence it. This
paper proposes a Particle Swarm Optimization (PSO) based multiobjective
function to tuning optimal parameters of Power System Stabilizer (PSS); this
later is used as auxiliary to generator excitation system in order to damp
electro mechanicals oscillations of the rotor and consequently improve Power
system stability. The computer simulation results obtained by developed
graphical user interface (GUI) have proved the efficiency of PSS optimized by a
Particle Swarm Optimization, in comparison with a conventional PSS, showing stable system
responses almost insensitive
to large parameter
variations.Our present study was performed using a GUI realized under MATLAB in
our work.
