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 ...
Electrical Modelling and Power Quality Analysis of Three-Phase X-Ray Apparatus
(Ieee, 2014-01-01)
This article proposes the use of PSCAD/EMTDC to model and simulate a three-phase x-ray machine. The model is an alternative tool to power quality studies, load connection impact analysis and power factor correction in the ...

Electrical modelling and power quality analysis of three-phase induction furnace
(2014-01-01)
The induction furnaces are loads having high power and nonlinear characteristic. The power consumption depends on the stage of melting metal in its interior and can cause serious problems on the electric power distribution ...
A comparison of three methods for monitoring CO2 migration in soil and shallow subsurface in the Ressacada Pilot site, Southern Brazil
(2014-01-01)
In a joint R&D project under the full sponsorship of PETROBRAS, the Brazilian National Oil Company, the first CO2 monitoring field lab was started-up in Brazil in 2011.The site chosen, the Ressacada Farm, in the Southern ...
Fault section estimation in electric power systems using an artificial immune system algorithm
(2008-01-01)
This work proposes an unconstrained binary programming (UBP) model for fault section estimation in power systems. UBP model consists in a set of equations that represent in a logical way the expected states of the relays ...
Multiloop controller and reference generator for a dynamic voltage restorer implementation
(2008-12-23)
This paper deals with the design and analysis of a Dynamic Voltage Restorer output voltage control. Such control is based on a multiloop strategy, with an inner current PID regulator and an outer P+Resonant voltage controller. ...
