Imposing Radiality Constraints in Distribution System Optimization Problems
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02-01)
Distribution systems commonly operate with a radial topology, so all models of optimization problems in these distribution systems should consider radiality in their formulation. This work presents a literature review, a ...
Analysis of the radial operation of distribution systems considering operation with minimal losses
(Elsevier B.V., 2015-05-01)
Electric power distribution systems, and particularly those with overhead circuits, operate radially but as the topology of the systems is meshed, therefore a set of circuits needs to be disconnected. In this context the ...
Comments, with reply on 'Continuous time relay-controlled model reference adaptive-system' by A. Abdulkareem and R. Nagarajam
(1989-07-01)
An adaptive scheme is shown by the authors of the above paper (ibid. vol. 71, no. 2, pp. 275-276, Feb. 1983) for continuous time model reference adaptive systems (MRAS), where relays replace the usual multipliers in the ...
A Real Test System For Power System Planning, Operation, and Reliability
(Springer, 2018-04-01)
Nowadays, several test systems available in the specialized literature are used to verify studies regarding power system planning or network reliability. However, there are no test systems currently available with enough ...
O papel dos sistemas visual, vestibular, somatosensorial e auditivo para o controle postural
(2011-08-01)
The maintenance of a given body orientation is obtained by the complex relation between sensory information and muscle activity. Therefore, this study purpose was to review the role of visual, somatosensory, vestibular and ...
Improving the grid operation and reliability cost of distribution systems with dispersed generation
(2013-02-01)
In this work, a mathematical model to analyze the impact of the installation and operation of dispersed generation units in power distribution systems is proposed. The main focus is to determine the trade-off between the ...
A Short Note on a Nonlinear System vibrations under Two Non-Ideal Excitations
(2003-10-01)
This paper describes a nonlinear phenomenon in the dynamical behavior of a nonlinear system under two non-ideal excitations: the self-synchronization of unbalanced direct current motors. The considered model is taken as a ...
Closed loop stability of measure-driven impulsive control systems
(Springer/plenum Publishers, 2010-01-01)
Closed loop stabilization of impulsive control systems containing a measure in the dynamics is considered. It is proved that, as for regular affine systems, an almost everywhere continuous stabilizing impulsive feedback ...
CONTROL OF UNCERTAIN DYNAMIC-SYSTEMS USING STRICTLY POSITIVE REAL SYSTEMS
(Springer, 1990-01-01)
This paper presents necessary and sufficient conditions to turn a linear time-invariant system with p outputs, m inputs, p greater-than-or-equal-to m and using only inputs and outputs measurements into a Strictly Positive ...
Information from managing information systems as a fundamental element to support decision-making in hospitals
(PONTIFICIA UNIVERSIDADE CATOLICA CAMPINAS, 2009)
This article deals with the activity of defining information of hospital systems as fundamental for choosing the type of information systems to be used and also the organizational level to be supported. The use of hospital ...
