Avaliação de eficiência energética residencial utilizando internet das coisas
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Engenharia ElétricaUTFPR, 2018-06-21)
Energy efficiency is achieved through the most varied methods, there are simpler ways, such as consumption reduction, until the development of more complex tools, such as creation of more efficient equipments using new ...
Efficient operative cost reduction in distribution grids considering the optimal placement and sizing of d-statcoms using a discrete-continuous vsa
(Cartagena de IndiasCampus TecnológicoIngeniería Eléctrica, 2021-03-02)
The problem of reactive power compensation in electric distribution networks is addressed in this research paper from the point of view of the combinatorial optimization using a new discrete-continuous version of the vortex ...
An Efficient Stochastic Reconfiguration Model for Distribution Systems With Uncertain Loads
(2022-01-01)
Active power losses of distribution systems are higher than transmission ones, in which these losses affect the distribution operational costs directly. One of the efficient and effective methods for power losses reduction ...
A computational comparison of 2 mathematical formulations to handle transmission network constraints in the unit commitment problem
(2017)
Until recently, transmission network constraints have been incorporated into the unit commitment (UC) problem (security-constrained UC [SCUC]) using the classical direct current (DC)-based equation. This paper proposes a ...
Inversor monofásico isolado conectado à rede baseado na topologia boost-full-bridge com redução ativa da ondulação de baixa frequência da corrente de entrada
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Sistemas de EnergiaUTFPR, 2020-08-17)
This Master’s Dissertation consists of the development of a boost-full-bridge topology isolated single-phase inverter with active reduction of the input current low frequency ripple through the unfolding methodology. The ...

A non-centralized predictive control strategy for wind farm active power control: A wake-based partitioning approach
(Pergamon-Elsevier Science Ltd, 2020-05)
Owing to wake effects, the power production of each turbine in a wind farm is highly coupled to the operating conditions of the other turbines. Wind farm control strategies must take into account these couplings and produce ...
Técnica de controle adaptativo robusto aplicada a filtros ativos de potência e paralelo
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2010-03-26)
The Methods for compensation of harmonic currents and voltages have been widely used since these methods allow to reduce to acceptable levels the harmonic distortion in the voltages or currents in a power system, and also ...
