The fault detection method (FDM) plays a crucial role in controlling and operating microgrids (MGs), because it allows for systems to rapidly isolate restore faults. Due the fact that MGs use inverter-interfaced distributed production, conventional FDMs are no longer appropriate they dependent on substantial currents. This study presents smart FDM based Hilbert–Huang transform (HHT) deep neural...

In this paper, we propose a variant of the Empirical Mode Decomposition method to decompose multiscale data into their intrinsic mode functions. Under the assumption that the multiscale data satisfy certain scale separation property, we show that the proposed method can extract the intrinsic mode functions accurately and uniquely.

BACKGROUND Compared to the waveform or spectrum analysis of event-related potentials (ERPs), time-frequency representation (TFR) has the advantage of revealing the ERPs time and frequency domain information simultaneously. As the human brain could be modeled as a complicated nonlinear system, it is interesting from the view of psychological knowledge to study the performance of the nonlinear an...

The synchrosqueezed transform was proposed recently in [Daubechies et al. (2009)] as an alternative to the empirical mode decomposition (EMD) [Huang et al. (1998)], to decompose composite signals into a sum of “modes” that each have well-defined instantaneous frequencies. This paper presents, for synchrosqueezing, a study similar to that in [Rilling and Flandrin (2008)] for EMD, of how two sign...

The interaction between the interplanetary medium and planetary environments gives rise to different phenomena on several temporal spatial scales. Here, we propose for first time, application of Hilbert-Huang Transform (HHT) characterize both local global properties Mercury's environment as seen during two Mercury Surface, Space Environment, Geochemistry Ranging (MESSENGER) flybys. In particula...
