Islanding Detection of IEEE 13 Bus System Based on Sequence Components

open access: yesInternational Transactions on Electrical Engineering and Computer Science, 2023
Islanding recognition in microgrids is crucial for enhancing power system safety and efficiency. This article presents a novel passive islanding recognition technique for grid integrated renewable Distributed Generation (DG) network.

A Secure Dual-Layer Fault Protection Strategy for Distribution Network with DERs: Enhancing Security in the Face of Communication Challenges

open access: yesSensors
Earlier protection methods mainly focused on using communication channels to transmit trip signals between the protective devices (PDs), with no solutions provided in the case of communication failure.

Exploring the sequential accumulation of metabolic syndrome components in adults

open access: yesScientific Reports, 2022
The metabolic syndrome (MetS) is diagnosed upon the manifestation of ≥ 3 out of 5 specific components, regardless of their combination. The sequence through which these components accumulate may serve to identify underlying pathophysiological mechanisms ...

Analysis on Circulating Current and Split Capacitor Voltage Balance for Modular Multilevel Converter Based Three-phase Four-wire Split Capacitor DSTATCOM

open access: yesJournal of Modern Power Systems and Clean Energy, 2021
We propose a modular multilevel converter (MMC) based three-phase four-wire (3P4W) split capacitor distribution static synchronous compensator (DSTATCOM), aiming at compensating unbalanced and reactive load currents.

Principal components analysis of protein sequence clusters [PDF]

open access: yesJournal of Structural and Functional Genomics, 2014
Sequence analysis of large protein families can produce sub-clusters even within the same family. In some cases, it is of interest to know precisely which amino acid position variations are most responsible for driving separation into sub-clusters. In large protein families composed of large proteins, it can be quite challenging to assign the relative ...

SEQUENCE OF BINOMIAL COMPONENTS IN ITALIAN AND CROATIAN LANGUAGE [PDF]

open access: yesHum, 2018
Unlike other idiomatic classes binomials are composed of two equally valuable elements mostly connected with the conjunction and. In the most European languages, as well as in Italian and Croatian, besides strong idiomaticity, they are mostly marked by ...

Active Control Method for Torsional Vibration of DFIG Drive Chain Under Asymmetric Power Grid Fault

open access: yesIEEE Access, 2020
When the asymmetric fault occurs in power grid, it will cause the oscillation of the electromagnetic torque of the doubly-fed induction generator(DFIG).

Representation stability for the cohomology of arrangements associated to root systems [PDF]

open access: yes, 2017
From a root system, one may consider the arrangement of reflecting hyperplanes, as well as its toric and elliptic analogues. The corresponding Weyl group acts on the complement of the arrangement and hence on its cohomology.

Component-by-component construction of shifted Halton sequences

open access: yes, 2015
We study quasi-Monte Carlo integration in a weighted anchored Sobolev space. As the underlying integration nodes we consider Halton sequences in prime bases $\boldsymbol{p}=(p_1,\ldots,p_s)$ which are shifted with a $\boldsymbol{p}$-adic shift based on $\boldsymbol{p}$-adic arithmetic. The error is studied in the worst-case setting.

Discrepancy estimates for sequences: new results and open problems

open access: yes, 2014
In this paper we give an overview of recent results on (upper and lower) discrepancy estimates for (concrete) sequences in the unit-cube. In particular we also give an overview of discrepancy estimates for certain classes of hybrid sequences.
