In this paper, a maximum likelihood (ML) estimator is applied for the estimation of power system oscillation modes. A regularization term is used in order to improve the estimation. An index is proposed to rank the modes and separate spurious from re

In this paper, a method for the identification of the synchronous machine parameters using data from field flashing (FF) and load rejection (LR) tests performed during commissioning, is proposed. The identification using data acquired during field fl

In this paper, subspace methods are applied to the identification of the dominant electromechanical oscillation modes of a large power system, using ambient data. The data are acquired by a low-voltage WAMS. Complementary techniques for the preproces

Robust design methods for power systems must deal with the fixed-structure of controllers and the system large dimension. This limits the applicability of the available design methods. In this paper, the power system stabilizer (PSS) design is posed

In this paper, optimization methods are applied to the design of power system stabilizers aiming to improve small-signal stability. Three performance indices are employed as objective functions, one of them taking explicitly robustness as a design re
