Impactos da geração distribuída nas redes de baixa tensão

Abstract

Given the growing demand for energy, and considering they are increasing the financial and environmental requirements for deployment of large generation projects, the generation connected to distribution networks and close to consumption centers are presented as an alternative to supply this demand. This generation is called Distributed Generation - DG and has the main advantage of reducing the transport from energy generation centers, mostly far from consumption centers. The reduction in transport means directly reducing losses in the system. From the above, and thanks to the industrial sector movement, the Brazilian Government through ANEEL - National Electric Energy Agency regulated, through Resolution 482/2012, the connection of the developments of DG to energy distribution networks. The inclusion of these sources of distributed generation represents a great challenge because it is a paradigm shift for the distributors, since it significantly changes the planning, operation and maintenance. This is because the inclusion of these units imposes a ring characteristic, with more than one direction for the power flow, on a system designed to work on a radial way. In this context, this monograph is intend to discuss the impacts that the integration of distributed generation sources will cause in the distribution networks of electricity low voltage, and contextualize how this process occurred in the major countries of the world's most advanced on the subject.
