Viability of Distributed Generation with Biogas and Photovoltaic in an Isolated System

Abstract

In the 1970s, the Brazilian oil crisis sparked interest in researching inexhaustible sources of energy. Within these sources of energy, those known as clean and abundant have become a viable alternative, reducing the pollutant capacity of waste, because the gas emitted by them in the decomposition that would previously go to the environment, is now destined for energy production and solid portion used as organic fertilizer [5]. This work aims to implement a case study to estimate the economic viability of the project, hybrid sources, in rural areas. The project in question will be analysed through software and mathematical methods, guaranteeing results close to those calculated analytically, compared to the energy sources studied as well as their feasibility and profitability through isolated distributed generation, which can bring fast and safe returns, such as a return of 84.37% biogas and 77.76% for photovoltaic compared to the initial investment over 25 years. Currently, Brazil suffers from a shortage of rainfall and consequently, with problems in the energy matrix, since the majority of Brazilian electricity comes from a hydroelectric power plant. Therefore, the purpose of this study is to present a solution and consequently self-sufficiency in rural areas, taking advantage of biodigesters and abundant sun to produce electricity.
