Geração de energia em horário de ponta nos centros urbanos a partir de fonte renovável

Abstract

A widely practice used in urban centers to reduce electricity consumption is the use of an engine generator set at peak hours. Currently, the peak hour kWh’s price is more than 4 times the off-peak price, depending on the tariff mode. For this reason, many companies, such as supermarkets, butchers, and even industries, turn on conventional S500 diesel-based generators to produce their own power and don’t use energy from power distribution company during the 3 rush hours. In this work, the possibility of fuel switch of these generator engines will be evaluated, replacing the S500 with biodiesel, including the analysis of technical and economic feasibility of this replacement. The impacts of using biodiesel on conventional diesel combustion engines will be presented through literature reviews. For economic analysis, the actual consumption of a midsize supermarket that already uses diesel generator at rush hours will be adopted as the basis of this study. Furthermore, alternatives are presented on how to obtain low cost biodiesel and equipments that enable its production. Finally, a comparison of these fuels replacement will be presented, covering the pro and cons of both situations considered in this study.
