Energia solar no Brasil em 2023 e sistemas de medidores de energia inteligentes para unidades com energia solar

Abstract

Distributed generation is something that has been gaining a lot of space in modern society. In Brazil, it began to be implemented through RN nº 482/2012, and allows the consumer to generate their own energy and inject the surplus into the concessionaire's network. Today, photovoltaic solar energy has been the main source of distributed generation in Brazil, representing over 95% of the total. In 2019, the country had 1GW of installed power, which doubled to 2GW in January 2022 and reached 3GW in June of that same year. Today, there is more than 11GW of installed Distributed Generation power in the country. In Brazil, in units with photovoltaic solar energy generation, a bidirectional meter installed by the concessionaire is used, which only measures the instantaneous difference between what is consumed. This in itself is quite limiting as it leaves the consumer unable to really monitor what is being generated and what is being consumed in their unit through their energy bill. This work is based on two academic works on smart meters, one of which is a master's thesis and the other a course completion work, and possible uses and solutions using this technology will be proposed.
