After extreme events such as floods, thunderstorms, blizzards and hurricanes there will be devastating effects in the distribution networks which may cause a partial or complete blackout. Then, the major concern for the system operators is to restore the maximum critical loads as soon as possible by available generation units. In order to solve this problem, this paper provides a restoration s...
in this paper, power system restoration in the presence of svc and tcsc in partial outage conditions is considered and a new method for maximum load restoration using different control variables is presented. control variables are tap of transformers, generation rescheduling and operating points of facts devices. objective function is restored load (to be maximized) and constraints are voltage ...
After a permanent fault occurs if it is not possible to supply the load in the network, the optimal load restoration scheme allows the system to restoration the load with the lowest exit cost, the lowest load interruption, and in the shortest possible time. This article introduces a new design called Smart Load Shedding, abbreviated SLS. In the proposed SLS scheme, the types of devices in smart...
One of the most important tasks of operators in distribution companies is to restoration after a fault in the network. In load restoration schemes, in addition to observing the load flow constraints, it is necessary to maintain the grid structure radially and, most importantly, observing the balance of consumption with the possibility of providing load due to the limitations of the backup feede...
Critical Load Restoration Using Distributed Energy Resources for Resilient Power Distribution System
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
در این مقاله کمانش پوستههای استوانهای شیار دار تحت بار محوری به روش تئوری و آزمایشگاهی مورد بررسی قرار گرفته است. پوسته ها از جنس فولاد با استاندارد (usa/api – x42 5l)در نظر گرفته شدهاند که یکی از پرکاربرد ترین مواد استفاده شده در صنایع گاز، نفت و پتروشیمی می باشند. اثر شیار مارپیچ برروی پوسته استوانه ای مورد تحلیل قرار گرفته است و در ادامه نتایج به دست آمده از نرم افزار abaqusبا نتایج آزمای...
Survivability is a critical network design issue for optical networks since even a single failure for a short duration may result in huge data loss due to the large capacity of optical fibers. However, few studies have been done on this issue for optical burst switching (OBS) networks. In this paper, we extend our early work on the fast restoration technique for OBS networks and present a novel...
in this study, the stability problem of a circular orthotropic cylindrical shell under the effect of anaxial compression varying with a power function of time is considered. at first, the modified donnell typedynamic stability and compatibility equations are obtained using love’s shell theory. applying the galerkinmethod and rayleigh-ritz variational techniques to these equations and taking the...
