Grid frequency regulation is essential for a reliable power grid. Whilst in distributed energy
sources,(DERs) power fluctuations arise from the imbalance of frequency. There are multiple …

Decaying DC (DDC) offset current mitigation is a vital challenge in phasor current estimation
since it causes malfunctioning/maloperation of measurements and protection systems. Due …

The sliding innovation filter (SIF) is a recently developed estimation technique that has
gained widespread use. It is a predictor-corrector filter that utilizes a hyperplane and applies …

Currently, microgrids are frequently used and various control algorithms have been applied
to improve their performance in both grid-connected and islanded modes. However …

This study presents the development of a new filter, the sequential sliding innovation filter
(SSIF), designed for estimating quantities of interest from noisy measurements. The SIF is …

The sliding innovation filter is a newly developed filter that was derived in 2020 to be a
predictor-corrector filter. The filter uses the measurement as a hyperplane, and then applies …

For the problem of multi-mode state estimation in actual train operation, this paper proposes
a nonlinear non-gaussian high-precision parallel Kalman filter group (NN-HEKFG) …

In recent years, research on three-dimensional (3D) reconstruction under low illumination
environment has been reported. Photon-counting integral imaging is one of the techniques …

The resolution accuracy of the inertial navigation system/global navigation satellite system
(INS/GNSS) integrated system would be degraded in challenging areas. This paper …

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 …
