Multi-terminal high-voltage direct current technology based on voltage-source converter stations (VSC-MTDC) is expected to be one of the most important contributors future electric power systems. In fact, among other features, it has already been shown how this can contribute improve transient stability in systems by use supplementary controllers. Along line, paper will investigate detail these...

Low frequency power oscillations may be triggered by many events in the system. Most oscillations are damped by the system, but undamped oscillations can lead to system collapse. Oscillations develop as a result of rotor acceleration/deceleration following a change in active power transfer from a generator. Like the operations limits, the monitoring of power system oscillating modes is a releva...

Present paper proposes maiden robust coordinated design of multi-channel (P-ω-δ) power system stabilizer (MPSS) and thyristor controlled series capacitor (TCSC) based power oscillation damping (POD) controller to enhance power system dynamic stability. Introducing advanced (P-ω-δ) PSS, for the first time, in coordination with the POD controller can provide more capable structure in damping of e...

In this paper, a class of second order forced nonlinear differential equation is considered and several new oscillation theorems are obtained. Our results generalize and improve those known ones in the literature.

In this paper, we study the oscillation of certain higher-order neutral partial functional differential equations with the Robin boundary conditions. Some oscillation criteria are established. Two examples are given to illustrate the main results in the end of this paper.

Due to its outstanding mechanical characteristics, diamond is an ideal material for use in micro- and nano-electromechanical systems. In this paper, we report on the investigation of vibrational properties singly clamped needlelike microcrystallites with nanoscale tips. The single-crystal needles were produced by selective oxidation polycrystalline films grown using chemical vapor deposition. s...

The letter describes a novel, continuum-based approach, to capture the evolution of electromechanical dynamics in power network following disturbance. Such approach is based on frequency divider formula (FDF) , which was recently proposed by third author. A key point obtaining frequency (FDF) a...

The power system industry has been going through dynamic infrastructural and operational changes in recent years that have caused more prominent lightly damped electromechanical oscillations. Real-time monitoring of electromechanical oscillations is of great significance for power system operators; to this aim, software solutions (algorithms) that use synchrophasor measurements have been develo...

Due to the deregulation in the electrical market, difficulties in building new transmission lines, and the continuous increase in power demand the maintenance of power system stability becomes difficult and a very challenging problem. In large, interconnected power system damping is often reduced, leading to lightly damped electromechanical modes of low frequency oscillations (0.1~0.6Hz). In th...
