In the field of power quality monitoring, due to the extensive quantity of measurements data,
it is preferred that the detection, identification and classification of Power Quality …

This letter explores accurate frequency and phase tracking for single-phase power grid
applications. While the conventional type-2 phase-locked loop (PLL) offers fast dynamic …

Parametric estimation of a biased harmonic signal is a significant technical challenge for
many engineering applications. Such a problem is particularly important for electric utility …

This paper proposes a exponential moving average extended Kalman filter (EMAF-EKF) for
the purpose of battery state-of-charge (SOC) estimation. The proposed approach relies on a …

Frequency tracking has been the focus of several research works for decades. One common
method is to utilize a state observer to dynamically estimate the frequency of the measured …

A novel instantaneous frequency (IF) tracking method for non-stationary measured signals
with single-frequency, multi-frequency, and harmonic-frequency is presented in this paper …

DC offset (DCO) in the input signal causes estimation inac-curacy in the phase-locked loop
(PLL) output. This letter provides a solution to DCO rejection while simultaneously offering …

Conventional second-order generalized integrator (SOGI) phase-locked loop, designed for
dc offset (DCO)-free measurements, experiences significant accuracy degradation in the …

In recent years, the generalized probability density evolution equation (GDEE) derived
based on the principle of probability conservation provided a new way for the analysis and …
