Análise dos impactos causados pela inserção de sistemas fotovoltaicos conectados a rede de distribuição utilizando o software opendss

Abstract

Brazilian economic growth imposes a growing demand for energy, according to the Brazilian Solar Energy Atlas. Linked to the rural electrification programs, a significant impact were possible, as there has been an increase of 3.2 million electrified rural households in the last 10 years (MME, 2015). Diversification of the Brazilian electric matrix is necessary, so the use of solar resources in Brazil is an excellent option to complement conventional sources of energy already consolidated such as hydroelectric. Solar energy is the one with the highest growth rates and great potential due to the privileged location of the country according to the Brazilian Solar Energy Atlas. In Tocantins, the generation of electricity through photovoltaic modules still has little participation and low impact on the total demand scenario of the utilities. electric power when compared to hydroelectric, despite the favored location position Tocantins presents to other states. The National Agency of Electricity has provided normative resolutions in which they provide the consumer to generate their own electric energy from renewable sources, which are: micro and mini generation of electric energy. These are innovations that can combine financial economy, social and environmental awareness and self-sustainability. Taking into account the huge expansion of Distributed Generation (DG) (GREENER, 2018) it is necessary to analyze the impacts that it has on the distribution grid.
