“…Comparing modal analysis with CPCA as described, we see that the coefficients w ij in (19) become very similar to the observability phasors φ ij in (2). Thus, if the decomposition successfully produces CPCs with frequency and damping similar to that of the modes of the system, then the coefficients w ij can be considered estimates of observability mode shapes.…”

“…This method, however, does not provide information about mode shapes. In [2], a method for estimating modes and mode shapes using various mode decomposition techniques and Power Spectral Density analysis is proposed. In [3], a Bayesian approach is proposed for monitoring of electromechanical modes.…”

“…As poucas abordagens que utilizam medidas de PMUs para identificar problemas oscilatórios em sistemas elétricos de potência procuram (i) estimar o modelo linear do sistema e calcular os autovalores (WANG; BIALEK; TURITSYN, 2018; YE; LI; LIU, 2020; MOU; YE; LIU, 2020) ou (ii) determinar os autovalores de baixo amortecimento diretamente (CHUNG;DAI, 2016;FERNANDES;Costa Júnior, 2017;KUMAR;KISHOR, 2017;XIE et al, 2005;UHLEN et al, 2008). No entanto, tais abordagens também são locais e avaliam a proximidade dos sistemas elétricos de potência de um problema oscilatório.…”
