The FACTS (Flexible AC Transmission System) devices have been considered as excellent controllers in a power system for better reliability and transmission capacity on a long-term and cost-effective basis. In this paper, a novel power flow controller topology is proposed for FACTS in order to improve static voltage stability characteristics and loading margin enhancement. Employing hybrid topol...

The paper mainly deals about the application of flexible AC transmission system (FACTS) to increase the power transfer capabilities for new operating scenarios in the bulk power systems. With the effect of FACTS technology improves transmission capabilities to reduce the system losses, and also improves the loadability of the power system. FACTs technology allows a better utilization existing t...

Ionic analytes, such as peptides, can be challenging to separate by reverse-phase chromatography with optimal efficiency. They tend, for instance, to exhibit poor peak shapes, particularly when eluted with mobile phases preferred for electrospray ionization mass spectrometry. We demonstrate that a novel charged-surface C18 stationary phase alleviates some of the challenges associated with rever...

The objective of an Optimal Power Flow (OPF) algorithm is to find steady state operation point which minimizes generation cost, loss etc. or maximizes social welfare, loadability etc. while maintaining an acceptable system performance in terms of limits on generators’ real and reactive powers, line flow limits, output of various compensating devices etc. This paper aims to find a solution for t...

Multi-phase (employing phases more than three) power transmission systems have been investigated as a potential alternative to conventional three-phase systems for bulk power transmission at EHV and UHV levels in the past. The technology has been found to be effective to remove some of the limitations of threephase system arising out of the use of extremely high voltages to increase power capab...

This paper presents the design and analysis of a compensation method with application to a 345 kV 480 MVA three-phase transmission line. The compensator system includes a series injected voltage source converter that minimizes the resonance effects of capacitor line reactance. This creates an ability to compensate for the effects of subsynchronous resonance and thereby increase line loadability...

Voltage stability analysis is the major concern in order to operate any power system as secured. In this context there are many research work has been carried out to improve the voltage stability. This study demonstrates the use of latest Power System Analysis Toolbox (PSAT) package for network analysis of alternative means of improving existing transmission system voltage stability. This paper...

Load flow analysis is an essential tool for the reliable planning and operation of interconnected power systems. The constant increase in demand, apart from increased intermittency generation due to renewable energy sources without proportionate augmentation transmission system infrastructure, has driven systems function nearer their limits. Though (PF) solution may exist such circumstances, tr...

In this investigation, a novel approach is presented to nd the optimum locations and capacity of Flexible AC Transmission Systems (FACTS) devices in a power system using a fuzzy multi-objective function. Maximising the fuzzy satisfaction allows the optimization algorithm to simultaneously consider the multiple objectives of the network to obtain active power loss reduction; i.e., new FACTS devi...

Received Jan 24, 2017 Revised May 4, 2017 Accepted Jun 10, 2017 In recent decades, one of the main management’s concerns of professional engineers is the optimal integration of various types of renewable energy to the grid. This paper discusses the optimal allocation of one type of renewable energy i.e. wind turbine to the grid for enhancing network’s performance. A multi-objective function is ...
