Frequency Regulation Provision Using Cross-Brand Bidirectional V2G-Enabled Electric Vehicles
(2018-10-18)
With the increasing number of electric vehicles (EVs) in use, concern about their impact on the power quality of local distribution grids is also increasing. However, efficient control of state-of-the-art EVs and their ...
Droidtracer: traçador de curvas de resposta em frequência
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia EletrônicaUTFPR, 2018-07-02)
The frequency response of a system is one of the most important tools to analyse and describe circuits and systems, whether they are known or not. The acquisition of the frequency response of electrical circuits can be a ...
Extension of a classic low frequency dielectric dispersion theory of colloidal suspensions to include different counterion and co-ion valences, a broad frequency range, and the stagnant layer conductivity
(American Chemical Society, 2012-11)
A unified extension of the classic Shilov-Dukhin theory of the low frequency dielectric dispersion of colloidal dispersions is presented. Purely analytical expressions for the AC dielectric and electrokinetic response over ...
Practical framework for frequency stability studies in power systems with renewable energy sources
(IEEE-Inst Electrical Electronics Engineers, 2020)
The transition from power systems dominated by synchronous machines to systems based on converter-based generation technologies (CGTs), is weakening currently robust power systems by reducing system inertia with the ...
Corona effect in frequency dependent transmission line models
(2008-12-01)
The inclusion of the corona effect in a frequency dependent transmission line model is proposed in this paper. The transmission line is represented through a cascade of π circuits and the frequency dependence of the ...

Design and Implementation of a Submersible Split Ring Resonator Based Sensor for Pisco Concentration Measurements
(IEEE, 2019)
The design of an Split Ring Resonator (SRR) based sensor is proposed for pisco concentration measurements through the characterization of the permittivity in liquids solutions containing pisco. The design is composed of ...
Glutamatergic and purinergic mechanisms on respiratory modulation in the caudal NTS of awake rats
(ELSEVIER SCIENCE BV, 2008)
In the present study we evaluated the role of ionotropic glutamate receptors and purinergic P2 receptors in the caudal commissural NTS (cNTS) on the modulation of the baseline respiratory frequency (fR), and on the tachypneic ...
Computation of Surge Voltage in Transmission Tower Located above Frequency-Dependent Soil
(2021-01-01)
The purpose of this paper is to investigate the influence of frequency-dependent soils with variable soil content on the transient voltages at transmission towers. First, a comparative analysis between the impedance of ...
