Ac-dc voltage profile and four point impedance of a quantum driven system
(American Physical Society, 2010-09)
We investigate the behavior of the time-dependent voltage drop in a periodically driven quantum conductor sensed by weakly coupled dynamical voltages probes. We introduce the concepts of ac-dc local voltage and four point ...
DC voltage profile of a 1D pumped wire with two dynamical and one static impurities
(Elsevier Science, 2009-10)
In this work we study the behavior of the voltage profile of a 1D quantum wire with an impurity when transport is induced by two ac voltages that oscillating with a phase lag define a quantum pump. The voltage profile ...
Evaluating the effects of high penetrations of roof-top wind Turbines on secondary distribution circuits
Incentives for using wind power and the increasing price of energy might generate in a relatively short time a scenario where low voltage customers opt to install roof-top wind turbines. This paper focuses on evaluating ...

Optimal Power Flow with Voltage-Sensitive Loads in Distribution Networks
Traditionally, the optimal power flow (OPF) assumes a constant (active and reactive) power load model and thus it neglects the effect of the voltage sensitiveness of power load injections. As a consequence, the results ...
Previsão de tensão em sistemas de distribuição considerando as possibilidades das redes inteligentes
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2012-11-09)
With the deployment of Smart Grids, the voltage quality has a new focus, and the ANEEL (National Agency of Electric Energy), Brazilian regulator organ, is able to improve its supervision activity. The electric energy ...
