Item Acesso aberto (Open Access) Comparação de métodos baseados em algoritmos genéticos para ajuste coordenado de estabilizadores de sistemas de potência(Universidade Federal do Pará, 2014-11-27) VIEIRA, Celivan Ferreira; VIEIRA, João Paulo Abreu; http://lattes.cnpq.br/8188999223769913This work presents a comparison study among three methodologies based on genetic algorithms applied to solve the power system stabilizers (PSS) tuning problem. The PSS tuning procedures are formulated as an optimization problem in order to: 1) maximize the closed-loop minimum damping ratio; 2) maximize the sum of the spectrum damping ratios; and 3) shift the lightly damped and undamped electromechanical modes of all plants to a prescribed zone in the s-plane. The three methodologies taking into account a pre-specified operating conditions. For this purpose, the system is represented by the state-space equations and the matrices associated with this modeling are obtained by using the academic version of the commercial software PacDyn. The simulations are carried out using the MATLAB plataform. The methodologies are applied to the well-known New England test system.
