This paper presents a technique for real-time predictionof stability/instability of a power system based on synchrophasor measurements obtained from phasor measurement units (PMUs) at generator buses.For stability assessment the technique makes use of system severity indices developed usingbus voltage magnitudeobtained from PMUs and generator electrical power. Generator power is computed using ...

Many operations in power grids, such as fault detection and event location estimation, depend on precise timing information. In this paper, a novel Time Synchronization Attack (TSA) is proposed to attack the timing information in smart grid. Since many applications in smart grid utilize synchronous measurements and most of the measurement devices are equipped with global positioning system (GPS...

This paper presents an adaptive wide-area control strategy based on energy function. The proposed method enhances the post-fault oscillation damping capability of Static Var Compensators (SVC) by incorporating load dynamics in controller design that adapts to variations. are obtained using Phasor Measurement Units (PMU) through power and voltage data measurements, which used estimate a Moving A...

Compared to traditional measurement devices, the micro-synchrophasor unit (D-PMU or μPMU) in distribution power system has great differences data acquisition frequency, format, dimension, time-stamped information, etc. Hence, it is imperative research integration mechanism of heterogeneous from multiple sources. Based on analysis current technology multi-source information fusion, this paper pr...

The art of tattooing is a popular decorative approach for body decoration and has corrective value the face. procedure characterized by placing exogenous pigments into dermis with number needles. process creating traditional cosmetic tattoos same. Colorants are deposited in piercing skin needles specific shape thickness, which moistened colorant. (pigments or dyes) most time include impurities ...

Islanding detection is a necessary function for grid connected distributed generators. Usually, islanding detection methods can be classified as two catalogues: remote detecting methods and local detecting methods. Most of them have limitation and defects when they are applied in photovoltaic power stations. Recently synchronous phasor measuring units (PMU) is proposed to be applied for islandi...
