The influence of silica fume on the apparent activation energy of HPC mixtures
(2005-09-01)
The use of the maturity approach has been increasing in various fields of concrete construction. In order to estimate the development of a mechanical property of the concrete mixture reliably, it is necessary to previously ...
Practical comparisons among electronic energy meters, a precision energy meter and IEEE1459 for reactive energy measurements, under unbalanced and non-sinusoidal conditions
(2012-12-01)
This paper presents a practical experimentation for comparing reactive/non-active energy measures, considering three-phase four-wire non-sinusoidal and unbalanced circuits, involving five different commercial electronic ...
Efficiency analysis of an isolated high voltage gain converter operating in resonant and non-resonant mode
(2012-12-17)
This paper presents an efficiency investigation of an isolated high step-up ratio dc-dc converter aimed to be used for energy processing from low-voltage high-current energy sources, like batteries, photovoltaic modules ...
Hybrid Stochastic/Information Gap Decision Theory Model for Optimal Energy Management of Grid-Connected Microgrids with Uncertainties in Renewable Energy Generation and Demand
(2021-01-01)
Microgrids (MGs) are considered a reliable solution for the integration of a high level of intermittent distributed energy resources. However, renewable energy generation has added complexity to the optimal energy management ...
Evolutionary heuristic to determine future land use
(2008-09-29)
In the spatial electric load forecasting, the future land use determination is one of the most important tasks, and one of the most difficult, because of the stochastic nature of the city growth. This paper proposes a fast ...
Reactive power support pricing of distributed generators with primary energy source uncertainty
(2011-05-31)
In this paper, a novel methodology to price the reactive power support ancillary service of Distributed Generators (DGs) with primary energy source uncertainty is shown. The proposed methodology provides the service pricing ...
Drying of persimmon: Mathematical model for diffusivity as a simultaneous function of moisture content and shrinkage
(Isnt Tecnologico Veracruz, 2001-01-01)
Fresh persimmon has a high moisture content (about 85% wet basis) making it highly perishable and requiring adequate drying conditions to obtain an acceptable dehydrated product. Drying kinetics of persimmon cv. Rama Forte ...
COMBUSTION and PYROLYSIS of A SLUDGE FROM WASTEWATER TREATMENT PLANT
(Trans Tech Publications Ltd, 2010-01-01)
The possibility of thermal treatment plants of municipal wastewater is an alternative solution for the final disposition of the sludge produced on small cities as Barueri, a small town of São Paulo State, Brazil. Combustion ...
Agent-Based Modeling of Peer-to-Peer Energy Trading in a Smart Grid Environment
(2021-01-01)
The energy system is undergoing a drastic transition towards a system where previously passive consumers will play important roles. These consumers who actively participate in the energy system with a variety of distributed ...
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 ...
