“…In this research study contribution is, two separate indices -contingency severity index (CSI) as in Malathy and Shunmugalatha (2016) and voltage collapse proximity index (VCPI) as in Naishan et al (2006) had been fused to formulate a unitification index (UI) to estimate line overloads and bus voltage deviation of the system for correct assessment of severity. Line CSI is used for the measurement of line overloads, where as VCPI had been preferred for voltage contingency ranking because of its simplicity makes numerical calculation easier.…”

This article addresses the efficient contribution of particle swarm optimisation (PSO) and its variants such as constrained factor-PSO (CF-PSO), Cauchy mutation-CFPSO (CM-CFPSO) and Gaussian mutation-CFPSO (GM-CFPSO) algorithm to choose suitable placement and rating of static synchronous compensator (STATCOM) based on novel index called unification index (UI). Minimisation of real and reactive power loss, voltage deviation reduction and augmentation of voltage stability are considered for this research work. UI is computed with respect to normal and generator contingency condition. Based on the index value, the ranking of severe lines is made. The purpose of embedding PSO with mutation is to expand the search space particularly to avoid being trapped in local optima. IEEE 30 bus system is chosen to assess the potency of the propound method using MATLAB working platform against generator bus contingency with and without STATCOM. This proposed approach yields promising result and their performances were presented and compared with other methodologies.

Currently, due to the global shortage of energy carriers the goal of more efficient use of the existing power sources and transmission lines is getting increasingly more important. At the same time, however, there is a known contradiction. In order to enhance the efficiency, we use advanced industrial electronics, rectifiers, frequency transducers, inverters, etc. This increases the efficiency of the technological plants, but at the same time the supply voltage suffers from an elevated level of harmonic components in the network. As is well known, nonlinear load generates harmonic components, resulting in a change of delivered power characteristics, namely indicators degrades the supplied power quality. In turn, the deterioration of the power quality leads to its overrun. In this regard, the problem of monitoring and reducing the harmonic components is relevant. Timely and accurate measurements based on data recorders vector quantities with high resolution, offers the prospect of continuous monitoring of the quality of power supply. The paper presents a system of continuous power quality monitoring. The system makes it possible to detect a source and a level of nonlinear distortions (harmonics), estimate the harmonic energy cost and control power quality parameters. Index Terms--Power quality, voltage and current harmonics, distributed monitoring of power quality, electric power systems, smart grids.

“…Hence VAR limit of the generator is more convoluted than active power limits. The generator's field current is controlled by over-excitation limiter to avoid damage of the field winding [5,6]. In power flow analysis program, reactive power limits are taken to be constant just for simplification.…”

Voltage stability estimation is one of the foremost parameter in monitoring the power system stability. Various voltage stability indices had been developed by researcher for voltage stability assessment. These indices were executed for spotting the pathetic transmission lines/buses. Here forth the placement and sizing of FACTS devices to trigger countermeasures against voltage instability/blackouts. In this paper two voltage stability indices were proposed called Synthesis Severity Index (SSI) and Compound Index (CI).These indices had been implemented on IEEE 14 and 30 bus system under generator and line contingencies. The resulted were presented and discussed.
