Rezumat
Aceasta lucrare propune o abordare metaeuristica pentru setarea optimala a stabilizatoarelor de putere (PSS) in
scopul imbunatatirii stabilitatii sistemelor electroenergetice prin amortizarea suplimentara a oscilatiilor de putere folosind
semnale de la Dispozitive de masura fazoriale (DMF). Asadar, problema destul de dificila a proiectarii PSS este transformata intr-o problema de optimizare care este rezolvata cu ajutorul algoritmului roiului de particule. Pentru atribuirea unui grad de performanta particulelor, se adopta o functie multiobiectiv care are la baza valorile proprii ale
sistemului. Performantele metodei propuse vor fi demonstrate prin intermediul analizei modale si a simularilor in domeniul
timp.

Abstract
This paper proposes a metaheuristic approach for optimal setting of power system stabilizers (PSS) in order to
increase the power system stability by supplementary damping of the system oscillations using PMU signals. The
complicated task of optimally determining PSS parameters is , thus, transformed into an optimization problem solved
using Particle Swarm Optimization algorithm (PSO). For evaluating the particles, an eigenvalue –based multiobjective
function is employed based on the system eigenvalues. The performances of the proposed approach are demonstrated
throughout modal analisys and time domain simulations
