Estudo de viabilidade de implantação do método CVR por meio de redes-modelo do IEEE

Abstract

In the national Brazilian scenario, it is common to run into information regarding low hydroelectric reservoir levels, power rationing, and short and medium-length power cuts. As alternatives to such seasonal risks, we can mention: an increase in energetic efficiency, new energy undertakings, national energy matrix diversification, among others. Most of these solutions are medium - and long-length achievements, plus all require much planning before coming into action. In the other hand, while looking for a short-length measure, we find out that CVR (Conservation Voltage Reduction), a researched method back at the 70’s throughout many countries, might fit our needs. CVR states that a reduction in the voltage supply level will reduce energy consumption. Due to the recent advances in smart-grids, the control of such voltage reduction can be improved. Having in mind the pursue of alternatives to mitigate the above mentioned problems, bringing more reliability of power supply to consumers, we have engaged in these studies. At first, this paper will study factors that might interfere for more or less favorable scenarios. Following, with the previous studies in mind, simulate scenarios of CVR through IEEE model-grids. At all times, keeping in mind that this method would be used in a national scenario, as a stopgap measure against the problems faced by energy generation and consumption, since most of Brazilian’s generation has its source in hydroelectric power plants, subject to seasonal factors, such as rain and drought.
