ORÇAMENTO DE CONEXÃO COM INVERSÃO DE FLUXO NO POSTO DE TRANSFORMAÇÃO

The amount of distributed generation power plants, especially photovoltaic ones, have increased significantly in Brazil and this growth is expected to continue for the next few years.

           During this research, an expressive increase in the connected distributed generation was observed, mainly between January 2022 and January 2023, due to consumers seeking to keep benefits prior to the promulgation of the Law 14.300 from January 6th, 2022.

This document has been elaborated to discuss the impacts caused by the power flow reversion caused by the excess of distributed generation and the alternatives available to enable new consumers connections, as established by the 73rd article from ANEEL nº 1000/2021 Normative Resolution.

Its main objective is to present the alternatives considered, its analysis and simulations, highlighting the viable options to allow a permanent power injection that serves the consumer. The pros and cons from the different ways analyzed are listed.

Under this context, energy storage technologies are discussed, focusing on the use of batteries, which can grant benefits in the distribution system that go beyond containing power flow reversion.
