A mixed-integer LP model for the reconfiguration of radial electric distribution systems considering distributed generation
(2013-01-21)
The problem of reconfiguration of distribution systems considering the presence of distributed generation is modeled as a mixed-integer linear programming (MILP) problem in this paper. The demands of the electric distribution ...
Optimal reconfiguration of electrical distribution systems using mathematical programming
(2014-01-01)
This paper presents a novel mixed integer nonlinear programming (MINLP) model for the reconfiguration problem of electrical distribution systems (EDS), aiming to reduce the active power losses of the system. Two linearization ...
Crowbar System in Doubly Fed Induction Wind Generators
(MOLECULAR DIVERSITY PRESERVATION INTERNATIONAL-MDPI, 2010)
In the last 15 years, the use of doubly fed induction machines in modern variable-speed wind turbines has increased rapidly. This development has been driven by the cost reduction as well as the low-loss generation of ...
An Efficient Stochastic Reconfiguration Model for Distribution Systems With Uncertain Loads
(2022-01-01)
Active power losses of distribution systems are higher than transmission ones, in which these losses affect the distribution operational costs directly. One of the efficient and effective methods for power losses reduction ...
Twelve weeks of supervised exercise improves self-reported symptom burden and fatigue in chronic kidney disease: A secondary analysis of the 'ExTra CKD' trial
(2019-01-01)
Background Chronic kidney disease (CKD) patients experience a high symptom burden including fatigue, sleep difficulties, muscle weakness and pain. These symptoms reduce levels of physical function (PF) and activity, and ...
Methanol tolerant electrocatalysts for the oxygen reduction reaction
(Springer, 2014-09-18)
Direct methanol fuel cells (DMFCs) represent an interesting alternative in obtaining electricity in a clean and efficient way. Portable power sources are one of the most promising applications of passive DMFCs. One of the ...
A novel electrocatalyst support with proton conductive properties for polymer electrolyte membrane fuel cell applications
(ELSEVIER SCIENCE BV, 2009)
The objective of this study is to graft the Surface of carbon black, by chemically introducing polymeric chains (Nafion (R) like) with proton-conducting properties. This procedure aims for a better interaction of the ...
Characterization of Casearin X Metabolism by Rat and Human Liver Microsomes
(2019-01-01)
Casearin X (CAS X) is the major clerodane diterpene isolated from the leaves of Casearia sylvestris and has been extensively studied due to its powerful cytotoxic activity at low concentrations. Promising results for in ...
