One of the key aspects of power quality improvement in power system is the mitigation of voltage sags/swells and flicker. Custom power devices have been known as the best tools for voltage disturbances mitigation as well as reactive power compensation. Dynamic Voltage Restorer (DVR) which is the most efficient and effective modern custom power device can provide the most commercial solution to ...

This project proposes a voltage stability for an interline photovoltaic (I-PV) system. In an I-PV system, the inverters in a PV plant are reconfigured in such a way that two or more distribution networks / feeder are interconnected. The I-PV system is operated as a flexible ac transmission system (FACTS) device STATCOM to regulate the point of common coupling voltage on either feeder. One of th...

The paper presents a novel modulated passive power filter scheme for nonlinear load bus voltage flicker control using an error-driven, error-scaled rule based controller for online voltage stabilization.

rapid expansions of new location-based services signify the need for finding accurate localization techniques for indoor environments. among different techniques, rss-based  schemes and in particular oneof its variants which is based on graph-based semi-supervised learning (g-ssl) are widely-used approaches the superiority of this scheme is that it has low setup/training cost and at the same ti...

Interconnection of wind generation with power distribution systems may result in rapid voltage variations, or flicker, much more readily than for HV transmission interconnections. Wind turbine generators employing doublyfed asynchronous generators provide a means to rapidly control reactive power, as well as to smooth variations in real power. This capability is exploited to minimize flicker, d...

An EMTP-based arc furnace model was developed for evaluation of flicker concerns associated with supplying a large integrated steel mill as they go from one to two furnace operation and as system changes are implemented that will affect the short circuit capacity at the 230 kV power supply substation. The model includes a dynamic arc representation which is designed to be characteristic of the ...

Single-channel properties of the Xenopus inositol trisphosphate receptor (IP3R) ion channel were examined by patch clamp electrophysiology of the outer nuclear membrane of isolated oocyte nuclei. With 140 mM K+ as the charge carrier (cytoplasmic [IP3] = 10 microM, free [Ca2+] = 200 nM), the IP3R exhibited four and possibly five conductance states. The conductance of the most-frequently observed...

This paper presents the design of a light chamber which can be used to investigate the flicker behaviour of various types of lamps. Using this system, a lamp can be subjected to a controlled voltage waveform while current and illuminance of the lamp are monitored. With the aid of such a voltage source capable of generating voltage fluctuations, including interharmonics and other power quality d...
