Reference generator for voltage controlled power conditioners
(2011-12-28)
Voltage reference generation is an important issue on electronic power conditioners or voltage compensators connected to the electric grid. Several equipments, such as Dynamic Voltage Restorers (DVR), Uninterruptable Power ...
Clarke's alpha, beta and zero components: A possible approach for the conceptual design of instrumentation compatible with IEEE Std. 1459-2000
(2004-10-08)
The paper explains the conceptual design of instrumentation that measures electric quantities defined in the trial-use Std. 1459-2000. It is shown how the Instantaneous-Space-Phasor (ISP) approach, based on α, β, 0 components, ...

Optimal allocation of distributed generators providing reactive power support ancillary service
(2011-10-05)
Problems as voltage increase at the end of a feeder, demand supply unbalance in a fault condition, power quality decline, increase of power losses, and reduction of reliability levels may occur if Distributed Generators ...
Selective Power Conditioning in Two-Phase Three-Wire Systems Based on the Conservative Power Theory
(2019-09-01)
AC power conditioners in electric power systems have been extensively explored in the literature based on approaches mainly focused on single- and three-phase wiring topologies, remaining a significant gap in regard to ...
Proposals for improvement of methodology and process of collecting and analyzing compatibility of power quality indicators in distribution systems
(2011-05-31)
This article aims to present proposals for improvement of key standards and resolutions concerned about the methodology for calculating the indicator of total harmonic voltage distortion, and should contribute to the process ...
Strategy for Flexible Operation of Three-phase Converters
(Ieee, 2016-01-01)
This paper depicts a multifunctional control strategy applied in three-phase inverters, which are connected to the distribution network. The proposed strategy is able to inject active power into the electrical grid and ...
