Prony analysis and matrix pencil method have been widely used for monitoring power system oscillations. In this paper, a performance study has been made on Prony analysis and matrix pencil method, which utilize single signal, as well as multiple signals, to estimate the dominant modes of oscillations. The performance of the two methods are evaluated on actual data obtained from PMUs interfaced to...
Harmonic, which is becoming more and more important day by day in the emerging power system, is one of the most critical power quality parameters. In this paper, the estimation of signal parameters via rotational invariance technique (ESPRIT)-based method is proposed with an accurate model order (the number of frequency components) estimate for power system harmonic and interharmonics detection. It...
