In this paper, a novel neuro-fuzzy based method combined with a feature selection technique is proposed for online dynamic voltage stability status prediction of power system. This technique uses synchronized phasors measured by phasor measurement units (PMUs) in a wide-area measurement system. In order to minimize the number of neuro-fuzzy inputs, training time and complication of neuro-fuzzy ...

Versa Module Eurocard (VME) backplane bus is a computer bus standard, originally developed for the Motorola 68000 line of CPUs, but later widely used for many applications and standardized by the IEC as ANSI/IEEE 1014-1987. It is physically based on Eurocard sizes, mechanicals and connectors (DIN 41612), but uses its own signalling system. This paper describes the general characteristics of the...

Wide-area backup protection (WABP) refers to the identification of faulted line amongst candidate lines by using sparse PMU measurements. This letter proposes a technique for reducing computational complexity WABP methods that employ superimposed-circuit concept. A proposition is presented and proved justify system equations pertaining every can be directly obtained from bus impedance matrix pr...

In this paper, a probabilistic neural network (PNN) based classifier is used to judge the static security of the power system. The proposed classifier classifies the security of the power system based on the voltage profile of each bus in reference to changes in the generation and load profile in the system. The probabilistic neural network is used and compared with the radial basis function ne...

Series of blackouts encountered in recent years in power system have been occurred because either of voltage or angle instability or both together was not detected within time and progressive voltage or angle instability further degraded the system condition, because of increase in loading. This paper presents the real-time assessment methodology of voltage stability using Phasor Measurement Un...

In deregulated power systems, the transmission loss allocation plays a key role in planning and designing of the power system. In practice, these losses should be allocated to both generators and loads depending on the amount of contribution in the total power system losses. In this paper, a new methodology to optimally allocate the transmission losses to either generators or loads based on the...

Improper management of reactive power in a network could lead to voltage instability. This paper presents well-detailed study on instability due violation equilibrium and introduces new stability pointer (NVSP). The proposed NVSP is developed from reduced 2-bus interconnected predict the sensistivity variation. simulation results MATLAB were evaluated IEEE 14-bus test system. contingency rankin...

in today’s restructured environment, congestion management plays an essential role in power system operation. different methods are presented and discussed in this respect for congestion management in short-term and long-term intervals. it is attempted in the present paper to investigate the impact mechanism of facts devices and demand response programs together with generation re-dispatch as s...

Received Jan 9, 2018 Revised Mar 2, 2018 Accepted Mar 18, 2018 The objective of this paper is to predict the secure or the insecure state of the power system network using a hybrid technique which is a combination of Artificial Neural Network (ANN) and voltage stability indexes. Voltage collapse or an uncontrollable drop in voltage occurs in a system when there is a change in the condition of t...
