The IEEE Standard C37. 118.1 defines two performance classes, P and M, for phasor
measurement units (PMUs), respectively for protection and monitoring oriented applications …

Frequency is one of the most important factors for power system harmonic and interharmonic
estimation. Accurate spectral analysis relies much on the correct identification of frequencies …

A complex-valued least-squares (CLS) framework is proposed in order to enhance the
accuracy of the smart discrete Fourier transform (SDFT) algorithms for power system …

Phasor measurement units (PMUs) are taking an increasingly important role in power

This paper focuses on the accurate frequency estimation of power signals corrupted by a
stationary white noise. The noneven item interpolation FFT based on the triangular self …

We present a dynamic frequency and amplitude estimation algorithm for unbalanced three-
phase power systems with harmonics. To develop the algorithm, we first construct a …

Efficient and accurate estimation of voltages and currents is essential for the control of
electrical grids, particularly microgrids. In this paper, we present a novel two-step framework …

This paper proposes a new distributed architecture to measure synchrophasors in power
substations, inspired by the standards IEC 61850. The new scheme is implemented in the …

Monitoring the voltage frequency is of great significance in power systems. In this paper we
propose two novel frequency estimators, namely the unbalanced HAM-WLS (UHW) …

This paper proposes a three-level discrete Fourier transform (DFT) method to provide an
accurate estimate of power system frequency in real time. The first level decomposes a …
