This paper proposes an empirical wavelet transform (EWT) based method for identification and analysis of sub-synchronous oscillation (SSO) modes in the power system using phasor measurement unit (PMU) data. The phasors from PMUs are preprocessed to c

Oscillations occurring in the power system are one of the biggest threats to its secure operation. Although they occur rarely, these oscillations can cause severe damage to the power system if they are not detected at the earliest. Hence, this work f

Accurate estimation of low frequency modes in the power system is vital for improving its small signal stability. Stochastic subspace identification (SSI) is a subspace based method which provides fairly accurate estimates of these low frequency mode

Identification of poorly damped low frequency oscillations present in the densely interconnected power system is of paramount importance to maintain its stable operation. Estimation of signal parameters via rotational invariance technique (ESPRIT) is

This work proposes a Fourier-EWT based methodology for tracking the modal parameters of low-frequency range electromechanical oscillations of the power system. It is essential to monitor the low-frequency electromechanical oscillations as poorly damp

This paper proposes a Hankels total least square (HTLS) based method for determining the modal parameters of the low frequency oscillations present in the power system. HTLS being a parametric method requires an estimate of the model order of the sig

Phasor Measurement Units (PMUs) are nowadays used to monitor and measure the bus voltages and the line currents emanating from the buses. For monitoring all the buses in the power system, optimal placement of PMUs for total power system observability
