Abstract
- The low‐frequency oscillation has become one of the most threatening problems of the electrical power system in the past few decades. The traditional Prony analysis method is seriously affected by noise and order estimation which cannot get the dominant oscillation sometime. A singular value decomposition‐difference differential method is proposed for order estimation of Prony mode. A parameter optimisation method based on interior point method is also proposed eliminating the noise effects on dominant model parameters. The proposed method has a fairly good property in noise suppression and dominant oscillation mode tracking. The suitability of the proposed method had been demonstrated in the simulation and case study. [ABSTRACT FROM AUTHOR]
