Análise da viabilidade da implementação de microrredes CC na Região Sul e Região Amazônica do Brasil

Abstract

Currently the distribution system is facing challenges to maintain the systems quality and reliability, with regard to the exponential growth of distributed generation (DG) and a scenery with plug-in electric vehicles (PEV). Therefore, it is vital to think about preventive measures to avoid the DG negatively impacting the electric power system while supporting the adoption of other technologies. Furthermore, it is observed a relevant demand of residential and comercial DC charge and when combined with DG, can bring efficiency and economic gains. The DC microgrid implementation can mitigate and even solve the impacts caused onto the electric power system and can provide electricity to remote locations, in a more efficient way. Thus, this work is aimed to the analysis the economic and socioenvironmental feasibility of DC microgrids implementation for for the South region and Amazon region of Brazil, estimating the consumption profile and efficiency energy for each scenario. Through sizing the microgrids in the Software HOMER Pro, payback, present worth, net present cost and return on investment is obtained. An estimate of the social and environmental transformation capacity of this technology is also carried out. The implementation of the CC microgrid proved to be viable under socio-environmental aspects for both scenarios, however, under economic aspects, it proved to be more viable for the microgrid in the South region. However, with a critical social analysis, it is possible to conceive that the implementation is feasible in both cases.
