Based on application practices of the CampusWAMS developed in Western Japan 60-Hz power system and Thailand power system, this paper presents a single-mode-oriented monitoring and estimation scheme of power system small-signal stability. The data filtering technique based on FFT is employed to extract oscillation data for single mode. The auto spectrum analysis is employed to compute the domina...

Nowadays, low frequency oscillation has become a major problem threatening the security of large-scale interconnected power systems.According to generationmechanism, active power oscillation of electric power systems can be classified into two categories: free oscillation and forced oscillation. The former results from poor or negative damping ratio of power system and external periodic disturb...

a chaotic optimization algorithm (coa) based approach for the robust coordinated design of the upfc power oscillation damping controller and the conventional power system stabilizer has been investigated in this paper. chaotic optimization algorithms, which have the features of easy implementation, short execution time and robust mechanisms of escaping from local optimum, is a promising tool fo...
