| description |
Since the beginning of this century, there has been an increasing need for energy supply and, consequently, an increase in international environmental concerns. In response to this demand, photovoltaic distributed generation appears as a possibility of reducing greenhouse gas emissions, as well as reducing investment in production, transmission, or distribution. Another form of control related to energy consumption is through management by the demand side, which in Brazil is an option for the residential sector with the new energy tariff, called white energy tariff. However, inserting these strategies and changing the new tariff regime requires investment and planning, which must be carefully analyzed. Computer simulations allow visualizing possible scenarios, facilitating the analysis, and encouraging future planning in this context. This paper assesses the effects of distributed photovoltaic generation and the new tariff regime of residential consumers that adhere to the white energy tariff. We studied housing units located in Bento Gonçalves, São Paulo, and Belém, with or without photovoltaic generation. We showed that only adherence to the white energy tariff generates a cost increase of 12.7%, 17.1%, 23.4% in the respective localities, which highlights, on the one hand, the need to change the typical consumer habits by reducing the use of electricity at peak times. On the other hand, cases with photovoltaic generation were more cost-effective with Conventional Tariff. Nevertheless, we observed Bento Gonçalves, where the difference was not significant. The best option was the white energy tariff because the peak consumption generated by the electric shower was removed by the insertion of a solar water heating installed with the photovoltaic system. In turn, this action led the dwellings to consume the minimum tariff, especially in São Paulo, where costs were equivalent regardless of the chosen tariff regime. |

In response to this demand, photovoltaic distributed generation appears as a possibility of reducing greenhouse gas emissions, as well as reducing investment in production, transmission, or distribution. Another form of control related to energy consumption is through management by the demand side, which in Brazil is an option for the residential sector with the new energy tariff, called white energy tariff.

In turn, this action led the dwellings to consume the minimum tariff, especially in São Paulo, where costs were equivalent regardless of the chosen tariff regime. Desde o início deste século, nota-se uma crescente necessidade de suprimento energético e consequentemente o aumento das preocupações ambientais internacionais. Em resposta a essa demanda, a geração distribuída fotovoltaica surge como possibilidade de redução das emissões de gases de efeito estufa, além da redução do investimento em produção, transmissão ou distribuição. Outra forma de controle referente ao consumo energético é por meio do gerenciamento pelo lado da demanda que, no Brasil, surge como opção para o setor residencial com a tarifa Branca. Porém, a inserção destas estratégias, assim como a mudança para o novo regime tarifário, requer investimentos e planejamento, os quais devem ser cuidadosamente analisados. Nesse contexto, as simulações computacionais possibilitam visualizar possíveis cenários, facilitar análises e fomentar planejamentos futuros. Este trabalho avalia os efeitos da geração distribuída fotovoltaica e do novo regime tarifário para consumidores residenciais que aderirem à tarifa Branca. Unidades habitacionais localizadas em Bento Gonçalves, São Paulo e Belém, com ou sem geração fotovoltaica, foram estudadas. Mostra-se que apenas a adesão à tarifa Branca gera 12,7%, 17,1%, 23,4% de aumento de gastos nas respectivas localidades, o que ressalta a necessidade da mudança nos hábitos atualmente típicos do consumidor e da redução no uso de energia nos horários de pico. Em contrapartida, os casos com geração fotovoltaica foram majoritariamente mais econômicos com a tarifa Convencional. No entanto, houve casos com resultado contrário em Bento Gonçalves, onde a diferença não foi relevante ou a melhor opção foi a tarifa Branca, visto que o pico de consumo gerado pelo chuveiro elétrico foi eliminado com a inserção do sistema solar de aquecimento de água que acompanhou o sistema fotovoltaico. Este, por sua vez, levou o consumo das habitações à tarifa mínima, principalmente em São Paulo, onde os custos foram praticamente os mesmos, não importando o regime tarifário escolhido.
