The increasing use of renewable generation, power electronic devices, and nonlinear loads in power systems brings more severe interharmonic tones to the measurand, which can increase estimation errors of P-class PMUs, cause misoperation of protection relays, and even threaten the stability of the power systems. Therefore, the performance of the P-class synchrophasor estimator under interharmonic interference should be evaluated and new estimation schemes that can improve the operational… 


A New Phasor Estimator for PMU Applications: P Class and M Class
The proposed methodology is based on finite impulse response filters, brick-wall filters, and complex filter design concepts, where frequency range, time performance, harmonic rejection and out-of-band interference requirements are considered in its design.

The results obtained indicate that the proposed algorithm can enhance phasor estimation performance by keeping maximum TVEs below 0.001% and 1% under frequency deviation and power modulation tests with OBI, respectively.
A Clarke Transformation-Based DFT Phasor and Frequency Algorithm for Wide Frequency Range
The Clarke transformation constructs a second signal that has exactly 90° phase angle difference from the original single-phase input signal and helps eliminate the estimation errors for a wide frequency range and can be used for other DFT-based synchrophasor algorithms in order to achieve higher synchROphasor measurement accuracy under dynamic conditions.
A Frequency-Domain Algorithm for Dynamic Synchrophasor and Frequency Estimation
A discrete Fourier transform (DFT)-based algorithm based on a dynamic phasor model (referred to as interpolated dynamic DFT-based synchrophasor estimator) is used to estimate not only amplitude and phase of the collected waveforms, but also their frequency and rate of change of frequency.
A Multiple Frequency Taylor Model-Based Dynamic Synchrophasor Estimation Algorithm
Simulation and field data test results demonstrate that the accuracy of the proposed algorithm is improved compared to the previous work from 0.98% to 0.04% of maximum total vector error under the dynamic modulations at the cost of an acceptable increment of computational burden.
Second‐order matrix pencil‐based phasor measurement algorithm for P‐class PMUs
Field data test shows that out-of-band signals have been reduced and the dynamic change of power system can be accurately reflected by phasor estimations, and results demonstrate that the proposed algorithm is suitable for P-class PMUs in complex power systems.

Comparison with other FIR based PMUs highlights advantages of the proposed solution such as high accuracy, good noise immunity, short response time and simple implementation.
Iterative-Interpolated DFT for Synchrophasor Estimation: A Single Algorithm for P- and M-Class Compliant PMUs
The method, called iterative-interpolated discrete Fourier transform (i-IpDFT), iteratively estimates and compensates the effects of the spectral interference produced by both a generic interfering tone, harmonic or interharmonic, and the negative image of the fundamental tone.
