Recently, distributed generation technologies have received much attention for the potential energy savings and reliability assurances that might be achieved as a result of their widespread adoption. Fueling the attention have been the possibilities of international agreements to reduce greenhouse gas emissions, electricity sector restructuring, high power reliability requirements for certain a...

Reliability is an important issue in electricity distribution systems, with strict regulatory policies and investments needed to improve it. This paper presents a mixed integer linear programming (MILP) model for clustering electrical customers, maximizing system reliability minimizing outage costs. However, the evaluation of its corresponding nonlinear function represent significant challenge,...

Due to the deregulation trend in electric power system networks, many factors have to be taken into consideration such as lack of supplying electric power, system reliability, power quality, electric system losses and voltage disturbance and profile problems. The excessive growing needs for electricity force electrical researchers to implement new approaches through the electric system. Introdu...

This article aims to incorporate the reliability model of power electronic converters into system analysis. The converter has widely been explored in device- and converter-levels according physics failure However, optimal decision-making for design, planning, operation, maintenance require system-level modeling electronic-based systems. Therefore, this proposes a procedure evaluate systems from...

ISSN 2250 – 1088 | © 2011 Bonfring Abstract--In this fast growing world, automating a distributing system is an effective means of providing a reliable system. There is an increasing interest in the quantitative assessment of power system reliability worth and its application to cost-benefit evaluation in power system planning. Hence this paper deals with automating a system using two stage res...

In this paper, simultaneous placement of distributed generation, capacitor bank and protective devices are utilized to improve the efficiency of the distribution network. The objectives of the problem are reduction of active and reactive power losses, improvement of voltage profile and reliability indices and increasing distribution companies’ profit. The combination of firefly algorithm, parti...

Several dozen studies of differential cognitive deficit appear each year. Artifacts cloud the findings in a majority of these studies because of differences in discriminating power of tasks coupled with generalized deficit of the patients. With two tests of differing reliability, the test with the higher reliability will yield greater performance deficit for the less able subjects. We argue for...

In this article, we consider the problem of estimating the stress-strength reliability $Pr (X > Y)$ based on upper record values when $X$ and $Y$ are two independent but not identically distributed random variables from the power hazard rate distribution with common scale parameter $k$. When the parameter $k$ is known, the maximum likelihood estimator (MLE), the approximate Bayes estimator and ...
