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 ...
the present study set out (a) to examine the categories of pedagogical knowledge related to the act of teaching of novice and experienced teachers as gleaned from their verbal report of what they were thinking about while teaching and (b) to compare the categories of pedagogical knowledge of novice and experienced teachers. the aim of comparing these two groups of teachers was to see whether di...
Skew is one of the most important parameter that decides the performance of the system. Though skews are reduced using two-stage(low and high voltage levels) serially connected power mode aware buffers(PMABs) using two power gating techniques-Fine grain technique at high voltage level and Coarse grain technique at low voltage level, the power consumption and area is large incase of fine grain t...
Power system is a highly interconnected nonlinear system that needs optimal and accurate control for continuous operation. Large power transfer through long transmission line between different electrical areas, stressed system and adverse interaction between local controllers, may give rise to slow frequency inter-area oscillations. The inter-area modes may not be visible from local measurement...
Nowadays the combined power generation system has become one of the most promising solutions to address the power needs of different regions. Given the discontinuity of energy produced by renewable sources a proven practice of combining these renewable energies can be a good solution for generating electricity in different atmospheric conditions, and with an appropriate combination of these sou...
The frequency control of reheat interconnected two area power systems are mainly characterized by non-linearity and uncertainty. A hybrid neural network and fuzzy control is proposed for load frequency control in the power systems considering governor dead band (GDB) non-linearity. Fuzzy with neural network is employed to forecast the control input requirement and system's future output, b...
Load Frequency Control (LFC) has received considerable attention during last decades. This paper proposes a new method for designing decentralized interaction estimators for interconnected large-scale systems and utilizes it to multi-area power systems. For each local area, a local estimator is designed to estimate the interactions of this area using only the local output measurements. In fact,...
The safe operation of power system depends on its stability and security supply in all times. The dynamic instability (small signal instability) is one of phenomena that results in power system instability and has been discussed as a challenge in power system control and operation from a long time ago. Commonly the dynamic instability appears as undamped low frequency electromechanical oscillat...
This paper is about the application of Capacitive Energy Storage unit (CES) to two area two unit powersystem to improve dynamic performance of automatic generation control. Simulation is done without CES, with CES unit by taking frequency error as control input and with CES unit by taking Area Control Error (ACE) as Control input. Simulation studies show that CES units are capable of reducing t...
