1. Technical and economic viability of the installation of a hybrid solar-wind generation system in a Brazilian industry
Abstract The demand for electricity is growing worldwide. At the same time, the non-renewable natural resources that account for a large proportion of the global energy matrix are rapidly depleting, which will pose a major challenge in the near future. Therefore, micro-grid models that use renewable energy sources, such as solar and wind, are rapidly develo

2. DECREASE IN OFF-PEAK ELECTRICAL ENERGY DEMAND BY AGROINDUSTRIES DUE TO PHOTOVOLTAIC SOLAR GENERATION
ABSTRACT The largest energy losses and voltage variations from electricity suppliers occur at times of peak demand. Daytime peaks are mainly influenced by large industrial and commercial consumers. The installation of photovoltaic systems without energy storage to supply part of the demand can contribute to stabilize the voltage and reduce losses. These and

5. Geophysical investigation of earth dam using the electrical tomography resistivity technique
Abstract Dams are structures that dam rivers and streams for a variety of purposes. These structures often need to be sturdy to withstand the force of the impoundment and the high values of accumulated water load. The constant maintenance of these structures is essential, since a possible accident can lead to damage of catastrophic proportions. This research

6. Aplicação de redes inteligentes nas instalações elétricas residenciais / Application of smart grid in residential electrical installations.
Electricity as an energy resource acquired vital importance in modern society because it allows relatively easily meet the demand for their services. Thus the demand for electricity increases with the evolution of populations who benefit from. The electrical system that produces this input is limited in its ability to available resources for generation, tran

7. SimulaÃÃo e avaliaÃÃo de um sistema de aquecimento solar de Ãgua utilizando balanÃo energÃtico / Simulation and evaluation of a system of solar water heating using energy balance
This work was developed at the State University of West of Paranà â UNIOESTE, campus de Cascavel and was aimed at developing a computer program to simulate and scale, optimally, a system of solar water heating. To determine the efficiency parameters of the system were installed three solar collectors of 1.05 m2 each, brand Pro Sol, coupled to a thermal res

9. La regulación de los servicios de electricidad en Argentina y Brasil (1890-1962)
This article compares the evolution of electric utility regulation in Argentina and Brazil between 1890 and 1960. From the installation of electrical systems in the 19th century until the 1930s, electrical utility companies were controlled by the local authorities in both countries. The structure of electrical systems was similar in Argentina and Brazil, how

10. Estimador de variações de tensão de curta duração em sistemas elétricos de potência utilizando estratégias evolutivas. / Estimate short duration voltage variation using evolutionary strategies.
A methodology is herein proposed to estimate Short Duration Voltage Variation (SDVV) in electric power systems, caused by electrical faults. To attain this target, values recorded by measurement equipment in specific sites are used. In fact, there are few power quality meters installed in power networks, due to the high cost of such meters. Although these co

11. Reconfiguração de redes de distribuição de energia elétrica usando algoritmo genético multiobjetivo
In this work, the reconfiguration of electrical energy distribution systems is studied by using a multi-objective genectic algorithm. Three objective functions are considered here: monetary costs of the network(installation, maintenance and energy losses), costs involved in the reability of the system and number of lines switching used for the reconfiguratio
