Due to the deregulation of the electrical market, difficulty in acquiring rights-of-way to build new transmission lines, and steady increase in power demand, maintaining power system stability becomes a difficult and very challenging problem. In large, interconnected power systems, power system damping is often reduced, leading to lightly damped electromechanical modes of oscillations. Implemen...

Digital Object Identifi er 10.1109/MPE.2011.943133 Date of publication: 13 December 2011 D DEREGULATION, MARKET TRANSACTIONS, CONGESTION MANAGEment, and the separation of functions have created increasing complexity that is making it diffi cult to maintain situational awareness and supervision of power system performance over large areas. Past reliability events (such as blackouts) have highlig...

Deregulation of electric utilities has led to a new competitive regime for utilities. In traditional systems, the main objective is to estimate voltages and flows. Estimators that include the ability to determine system parameters along with system (conditions have been developed. In the evolving deregulated environment there are a host of new estimation needs. The various costs of the particip...

This paper presents application artificial intelligent (AI) techniques, namely artificial neural network (ANN), adaptive neuro fuzzy interface system (ANFIS), to estimate the real power transfer between generators and loads. Since these AI techniques adopt supervised learning, it first uses modified nodal equation method (MNE) to determine real power contribution from each generator to loads. T...

Smart Grid is an Information and Communication Technology (ICT) enabled Power grid. It is efficient, secure, reliable and self-healing power grid. Integration of micro grids, electric vehicles and other utilities make it more interesting. The deregulation of electricity sector has necessitated the use of many advanced software and embedded technologies to handle the size and complexity of power...

A big step forward to improve power system monitoring and performance, continued load growth without a corresponding increase in transmission resources has resulted in reduced operational margins for many power systems worldwide and has led to operation of power systems closer to their stability limits and to power exchange in new patterns. These issues, as well as the on-going worldwide trend ...

Objective(s): MicroRNAs (miRNAs) are a subfamily of small noncoding RNAs that play a variety of roles in regulating gene expression in nearly all organisms. They affect different biological pathways by post-transcriptionally regulating mRNAs. Aside from miRNAs’  role in maintaining cellular homeostasis, their perturbation is related to several pathologic states and dis...

With the increasing electric power demand, power systems can face to stressed conditions, the operation of power system becomes more complex, and power system will become less secure. Moreover, because of restructuring, the problem of power system security has become a matter of concern in deregulated power industry. Better utilization of available power system capacities by Flexible AC Transmi...
