Estudo de potencial energético regional para inserção na matriz elétrica : o caso da geração a biogás na região oeste do Paraná

Abstract

The main objective of this thesis is to evaluate the energy potential of biogas in 54 cities in the western region of Paraná, to supply part of the electrical demand by 2026. First is presented a survey about energy planning in different geographic areas (national, regions, states, cities and groups of cities). Next, a critical assessment of the insertion of distributed energy resources in the distribution networks is carried out, focusing on distributed generation (which has shown a rapid growth rate in Brazil). Due to the vast availability of organic waste from agricultural and livestock activities, it was estimated that the western region of Paraná state could produce 1.1 million Nm³/day of biogas and 59.2 MWm of electricity, only in rural properties and slaughterhouses. If solar photovoltaic and hydropower potentials are added, the overall theoretical potential of renewable sources for electricity generation in this region would be 3,252,423 MWh/year (or 371.3 MWm). This amount is equivalent to 82.7% of local demand in 2016 and would be in the range between 40.9% and 48.8% of the consumption projection for 2026 (depending on the scenario).
