Autor/autori: Eng. Andrei STATIVA PhD Student, Prof. Eng. Mihai GAVRILAS PhD

Rezumat: Aceasta lucrare propune o abordare metaeuristica pentru setarea optimala a stabilizatoarelor de putere in scopul imbunatatirii stabilitatii sistemelor electroenergetice prin amortizarea suplimentara a oscilatiilor de putere. Pentru asigurarea unui grad suficient de stabilitate, se utilizeaza o functie obiectiv care are la baza analiza modala. De asemenea,este prezentata si o metoda de comunicare automata intre Matlab si DigSILENT pentru rezolvarea problemei de optimizare studiate.

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. To ensure a sufficient degree of relative stability, an eigenvalue-based objective function is employed. Also, a technique for automatic data exchange between Matlab and DigSILENT for solving the optimization problem is presented.

Keywords: DPL, DigSILENT, eigenvalues, power system stabilizer, power system stability
