Due to dynamic nature of loads, total system load is more than its generation capacity that makes relieving of load on the feeders not possible and hence voltage profile of the system will not be improved to the required level. In order to meet required level of load demand, Reconfiguration and DG units are integrated in distribution network to improve voltage profile, to provide reliable and u...

This paper proposes a Neural Network-Based method for on-line maximum loadability estimation, for an optimized power system voltage stability profile. A simulated annealing optimization technique for optimal voltage stability profile through out the whole power network was used. The minimization of the voltage stability index at each individual load bus as well as the global voltage stability i...

Different load centers where the energy is utilized are connected to the generating stations through high voltage transmission systems and a low voltage distribution systems. The losses occurring in the distribution network amount to nearly 40% of the total losses. Optimally located Distributed Generation (DG) systems offer multiple benefits in reducing the losses and supplying quality power. I...

the harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. this paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. the objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...

In modern days power system are becoming highly unpredictable, so low voltages and blackout are becoming common scenario. The voltage limits are affected because the system is operated close to its stability limits. To improve the voltage profile new generating plants have to be developed, which are restricted due to economic an environmental limitations. To overcome these limitations and use t...

distributed generations (dgs) are utilized to supply the active and reactive power in the transmission and distribution systems. these types of power sources have many benefits such as power quality enhancement, voltage deviation reduction, power loss reduction, load shedding reduction, reliability improvement, etc. in order to reach the above benefits, the optimal placement and sizing of dg is...

The inductively coupled plasma etching characteristics of Co2MnSi thin films patterned using a TiN hard mask were investigated by the addition of CH3OH to Ar gas. As the CH3OH concentration increased, the etch rates of Co2MnSi magnetic thin films and TiN hard mask decreased, but the etch profile improved. The effects of rf power, dc-bias voltage and gas pressure on the etch rate and etch profil...
