Abstract :
In recent days, as power systems are operated close to the stability margin, oscillation caused by lack of damping torque is frequently observed. Power System Stabilizer (PSS) enhances generator stability by providing a supplementary signal to the automatic voltage regulator which enhances the damping torque. Stochastic Subspace Identification (SSI) algorithm is applied to obtain a linearized single-input-multiple-output model of a power system and the Linear Matrix Inequality (LMI) approach is then used to design several PSSs. Typical results are presented for the LMI-SSI model based PSS design on the IEEE 68 16- machine power system.
