Rezumat
In aceasta lucrare este propusa o metoda inovatoare de abordare a problemelor de stabilitate prin utilizarea simultana a doua aplicatii, si anume, Matlab (MathWorks) si DIgSILENT (PowerFactory). Astfel, intre cele doua aplicatii se creaza o interfata de comunicare care foloseste ca strat intermediar de comunicare, fisiere cu extensia .csv. In problema
proiectarii optimale a stabilizatorului de putere folosind abordari metaeuristice, aceasta aplicatie se poate folosi cu succes usurand semnificativ intreg procesul de determinare a parametrilor PSS. Prin urmare, algoritmul de optimizare este
implementat in Matlab, iar sistemul electroenergetic si controlerele sunt modelate in DIgSILENT. Descrierea intregului proces de comunicare este prezentat in cadrul unei aplicatii practice care consta in optimizarea parametrilor PSS in ipoteza folosirii semnalelor de la distanta. Aceasta abordare nu se restrange doar la problema proiectarii PSS, ci poate fi
folosita in orice problema care necesita utilizarea simultana a celor doua aplicatii.

Abstract
In this paper, a novel method is proposed in approaching power system stability problems by using
simultaneously two applications, in terms of Matlab (MathWorks) and DIgSILENT (PowerFactory). Thus, between these
applications a communication interface is created that uses as a link layer .cvs files. In the complicated problem of
designing power system stabilizer using metaheuristics, this application can be used successfully simplifying considerably
the whole searching process. Accordingly, the optimization algorithm is implemented in Matlab and the power system and
the controllers are modeled in DIgSILENT. The whole process will be presented throughout an application that involves the
optimal tunning of PSS considering using remote signals from key points of the network as inputs. This model doesn’t
apply only to the problem of determining the PSS parameters, but it can be used in any problem that envolves both
platforms working together.
