A selective harmonic compensation and power control approach exploiting distributed electronic converters in microgrids
(2020-02-01)
This paper proposes an approach to obtain harmonic compensation and power control by exploiting the electronic power converters deployed in low-voltage microgrids. By the proposed approach, distributed harmonic current ...
Insertion of distributed generation into rural feeders
(IEEE, 2009)
The connection of renewable energy distributed generators (DG) to radial feeders is assessed. Often, the long distance between renewable power sources and the transmission system, in addition to the small capacity of these ...
A true programmable HPF hybrid three-phase rectifier
(2008-09-29)
In this paper is proposed and analyzed a digital hysteresis modulation using a FPGA (Field Programmable Gate Array) device and VHDL (Hardware Description Language), applied at a hybrid three-phase rectifier with almost ...

Metodologia de análise do colapso de tensão em tempo real considerando limites de potência ativa e reativa de geradores
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Sistemas de EnergiaUTFPR, 2017-09-29)
Due to the high energy demand and the high complexity of today's interconnected Electrical Power Systems (SEPs), it is becoming increasingly important for the system operator to know the current state of the SEP. In addition, ...
Location of single line-to-ground faults on distribution feeders using voltage measurements
(2006-12-01)
This paper proposes a dedicated algorithm for lation of single line-to-ground faults in distribution systems. The proposed algorithm uses voltage and current phasors measured at the substation level, voltage magnitudes ...
On the control of a non-ideal engineering system: A friction-driven oscillating system with limited power supply
(2003-01-01)
In this work a switching feedback controller for stick-slip compensation of a 2-DOF mass-spring-belt system which interacts with an energy source of limited power supply (non-ideal case) is developed. The system presents ...
