[pt] GERAÇÃO DE CENÁRIOS SINTÉTICOS COM GRANULARIDADE HORÁRIA PARA PRODUÇÃO ENERGÉTICA DE USINAS DE BIOMASSA / [en] SYNTHETIC SCENARIOS GENERATION WITH HOURLY GRANULARITY FOR ENERGY PRODUCTION FROM BIOMASS POWER PLANTS

GABRIEL CALVO MARTINEZ 26 October 2021 (has links)
[pt] As fontes renováveis de energia tem adquirido grande relevância no contexto mundial devido as diretrizes tomadas pelas políticas globais. Embora sejam termoelétricas, as usinas a biomassa são consideradas fontes de energia renováveis por manter os níveis de gás carbônico na atmosfera. Além disso, as usinas termoelétricas têm mais autonomia na geração do que as demais fontes renováveis como hidrelétricas, eólicas e solares que dependem de incertezas como vazões de água, velocidade do vento e irradiação solar, respectivamente. Este conjunto de características torna a biomassa uma fonte de energia indispensável para futuros planejamentos de operação do sistema. No entanto, esta fonte apresenta períodos intermitentes por estar usualmente atrelada a cultura de cana-de-açúcar. Poucos são os estudos de previsão e simulação desta fonte de energia. Dessa forma, a dissertação visa a implementação do modelo de cadeias de Markov com simulações de Monte Carlo. / [en] Renewable energy sources have acquired great relevance in the world context due to the guidelines taken by global policies. Although they are thermoelectric, biomass power plants are considered renewable energy sources because they maintain the levels of carbon dioxide in the atmosphere. In addition, thermoelectric plants have more autonomy in generation than other renewable sources such as hydro, wind and solar, which depend on uncertainties such as water flow, wind speed and solar irradiation, respectively. This set of characteristics makes biomass an indispensable energy source for future system operation planning. However, this source has intermittent periods as it is usually linked to the sugarcane crop. There are few prediction and simulation studies of this energy source. Thus, the dissertation aims to implement the Markov chain model with Monte Carlo simulations.
