This paper concerns compute and exploiting the sensitivity of the loading margin to voltage collapse with respect to various parameters. The main idea of this paper is that after the loading margin has been computed for nominal parameters, the effect on t... see more

Nowadays the biggest challenge of the electrical power transmission system is voltage collapse. As a result, these days a major outlook has been paid with the aid of a variety of research on voltage stability. In this paper, a method has been introduced t... see more

Capacitance micromachined ultrasonic transducers (CMUTs) have become an attractive alternative to the piezoelectric transducers, especially in air-coupled nondestructive evaluation (NDE) and ultrasound medical imaging flow metering,  micro/nanoelectr... see more

Las partes estables de las curvas P-V y Q-V pueden ser calculadas mediante el uso de los flujos de cargas convencionales. Este trabajo presenta la implementación de un método estático para los análisis de la estabilidad de tensión. Esta metodología consid... see more

This paper investigates the enhancement in voltage stability achieved while connecting a variable speed wind turbine (VSWT) driven electrically excited synchronous generator (EESG) into power systems. The wind energy conversion system (WECS) uses an AC-DC... see more

Due to the increase in electricity demand, transmission sector has become overstressed since it can only be built at vast cost. In many developing economies, the network is highly susceptible to outages, collapse as well as partial or total failures, sinc... see more

The grid fragility is a prevalent challenge in Nigeria electricity supply industry (NESI).  It has resulted in recorded incidents of voltage collapse which have been on the increase in the recent time. Meanwhile to evaluate this events; thus the nexu... see more

ABSTRACT: Microgrids are used as controllable units connected to power grid, in which the electrical distances between reactive power sources and the loads that need the reactive compensation are not too much. Thus, a coordinated compensation of rea... see more

In the present paper SiN thin film has been studied as a passivation layer and its effect on AlGaN/GaN HEMTs is investigated using two different deposition techniques i.e PECVD and ICPCVD. AlGaN/GaN HEMTs devices passivated with optimised SiN film have de... see more
