Análise de perdas em sistemas de distribuição com a inserção de geração distribuída

Abstract

Distributed generation (DG) has gained recognition around the world, including in Brazil, where promotion and incentive policies and the integration of renewable energy sources into electrical grids have been implemented. This highlights the importance of the global trend towards a more diverse and sustainable energy matrix. Its introduction represents a significant change in the traditional electrical system, requiring adaptations from distributors to remain efficient and competitive in this new scenario. The proximity of generation sources to consumers presents a series of advantages, both for companies responsible for the transmission and distribution of electrical energy and for end consumers. Firstly, this proximity results in considerable savings in expenses related to the operation and maintenance of transmission and distribution lines, reducing losses and the need for safety devices. Furthermore, the use of energy generated at the point of consumption is capable of not only reducing losses but can also contribute to reducing the costs that fall on final consumers, making distributed generation a more attractive option in comparison with the generation and distribution of energy over long distances. Given this, the present work seeks to identify specific scenarios, including the strategic location of DG and variations in load demand, in which the incorporation of distributed sources of electrical energy results in a substantial reduction in losses in the system, contributing to efficiency and the sustainability of the electrical system.
