A assinatura do Acordo de Paris e a elaboração do Roteiro Para Neutralidade Carbónica
em 2050 impõem objetivos para a introdução de fontes de energia renovável no contexto
português, aumentado a penetração da energia fotovoltaica em diferentes setores do sistema
energético nacional. Neste contexto, o armazenamento de energia torna-se um elemento-
chave para maximizar a utilização do recurso solar e para contribuir para a redução de custos.
O presente trabalho visa o desenvolvimento de um sistema que utiliza a flexibilidade
energética disponibilizada por baterias, com o objetivo de maximizar o autoconsumo em
sistemas de geração fotovoltaica e reduzir os custos relativos ao consumo de energia elétrica.
As operações do sistema em ambiente real, indicam o alcance do objetivo proposto, com uma
redução nos custos de faturação em 49% e um aumento absoluto do autoconsumo em cerca
de 31%, em relação a um cenário base com apenas geração e sem armazenamento.
Adicionalmente, durante as análises comparativas entre os cenários propostos, foi identificada
uma oportunidade de melhoria do sistema em questão, onde seria possível atingir uma
redução nos custos em 50% e um aumento absoluto no autoconsumo de 48%.

In this context, energy storage becomes a key element to maximize the use of solar resources and to contribute to cost reduction. The present work aims to develop a system that uses the energy flexibility provided by batteries, with the objective of maximizing self-consumption in photovoltaic generation systems and reducing costs related to electricity consumption. The system's operations in a real environment indicate the achievement of the proposed objective, with a reduction in billing costs by 49% and an absolute increase in self-consumption of about 31%, compared to a base scenario with only generation and without storage. Additionally, during the comparative analysis between the proposed scenarios, an opportunity to improve the system in question was identified, where it would be possible to achieve a reduction in costs by 50% and an absolute increase in self-consumption of 48%.
