Advanced power system nowadays demands to ensure accurate estimate of the system states (bus voltages and angles) in order to ensure protection, monitoring, controlling and smooth running of the system. The conventional state estimator estimates the power system states based on the measurements obtained from the Supervisory Control and Data Acquisition (SCADA) system. Besides, the use of synchr...

The number and intensity of forest fires in the United States have been steadily increasing causing massive economic ecological damage. Overhead transmission distribution lines are typically disconnected preemptively near fires, a practice that causes high social cost. Deployment Phasor Measurement Units (PMUs) their ability for synchronized real-time measurement voltage current inspire here pr...

In animals, odor qualities are represented as both spatial activity patterns of glomeruli and temporal patterns of synchronized oscillatory signals in the primary olfactory centers. By optical imaging of a voltage-sensitive dye (VSD) and intracellular recording from secondary olfactory interneurons, we examined possible neural correlates of the spatial and temporal odor representations in the p...

Voltage instability is a crucial issue in the secure operation of power grids. Several methods for voltage stability assessment were presented. Some of them are highly computationally intensive, while others are reported not to work properly under all circumstances. This paper proposes a new methodology based on the generator equivalent circuit model (GECM) and the phasor measurement unit (PMU)...

Measurement of magnitude and frequency of the voltage flicker is very important for monitoring andcontrolling voltage flicker efficiently to improve the network power quality. This paper presents twonew methods for measurement of flicker signal parameters using Shuffled Frog Leaping Algorithm(SFLA) and Imperialist Competitive Algorithm (ICA). This paper estimates fundamental voltage andflicker ...

In the context of renewable energy integration into the distribution grid, this paper proposes introduces the concept of synchronized control of many inverters distributed on a low voltage network. Compared to the standard Volt-VAr control, the synchronized control presents substantial advantages. It can better control voltage on a line and add further services such as reactive power compensati...

Gwanghyeon Baek (SID Student Member) Jerzy Kanicki (SID Member) Abstract — The equations for the transfer characteristics, subthreshold swing, and saturation voltage of double-gate (DG) a-IGZO TFTs, when the topand bottom-gate electrodes are connected together (synchronized), were developed. From these equations, it is found that synchronized DG a-IGZO TFTs can be considered as conventional TFT...

there are fewer problems encountered with optical voltage transducers in comparison with their inductive and capacitive counterparts. although capacitive and inductive transformers are used vastly for the purpose of measurement and protection in the networks, they cause problems such as core saturation and improper transient responses which decrease the accuracy of measurement and eficiency of ...

With the rapid growth of usage of phasor measurement units (PMUs) for modern power grids, the application of synchronized phasors (synchrophasors) to real-time voltage security monitoring has become an active research area. This paper presents a novel approach for fast determination of loading margin using PMU data from a wide-area monitoring system (WAMS) to construct the voltage stability bou...
