“…Recently, the WAMS (Wide Area Measurement System) related technologies are rapidly being developed in power system in order to enhance the power system stability [1][2][3][4][5]. In the WMAS, an accurate and fast estimation of the lowfrequency oscillation parameters is a very important part in analyzing, controlling and operating a wide area power system.…”

-This paper presents a DFT (Discrete Fourier Transform) based estimation algorithm for the parameters of a low-frequency oscillating signal. The proposed method estimates the parameters, i.e., the frequency, the damping factor, the mode amplitude, and the phase, by fitting a discrete Fourier spectrum with an exponentially damped cosine function. Parameter estimation algorithms that consider the spectrum leakage of the discrete Fourier spectrum are introduced. The multi-domain mode test functions are tested in order to verify the accuracy and efficiency of the proposed method. The results show that the proposed algorithms are highly applicable to the practical computation of low-frequency parameter estimations based on DFTs.

Abstract-Role of multiple HVDC links -both CSC and VSC -in improving the AC system dynamic performance is presented here. An Australian equivalent system with three critical interarea modes is considered to illustrate the case study on DIgSI-LENT PowerFactory. Subspace-based multi-input-multi-output (MIMO) system identification is used to estimate and validate linearized state-space models through pseudo random binary sequence (PRBS) probing in DIgSILENT PowerFactory. Choice of appropriate input-output combinations is done through modal residue analysis taking note of not only the magnitudes but also the phase angles. The decentralized control design is posed as an optimization problem and solved using an evolutionary technique. The results are validated through linear analysis and non linear simulation in DIgSILENT for two extreme (light and heavy loading) operating conditions.

“…Recently, many countries have deployed wide-area monitoring systems (WAMS) using synchronous phasor measurement units (synchrophasors) for wide-area grid monitoring and control [5][6][7][8]. Synchrophasor technology measures the phasor of the signal by synchronizing the time of the measurement data with time derived from satellite clocks [9].…”
