O método tem como objetivo minimizar a compra de energia da rede externa aplicando a ferramenta de otimização Recozimento Simulado para determinar o perfil diário de carga e descarga do banco de baterias, considerando restrições técnicas e operacionais. Nas simulações foram consideradas a dinâmica da demanda e da disponibilidade de recurso solar, bem como da tarifa de energia ao longo do dia, aproveitando a energia armazenada em momentos de tarifa mais barata e maior disponibilidade de geração solar em momentos de pico, reduzindo assim o custo diário de operação. Os resultados evidenciaram a aplicabilidade da ferramenta de otimização, determinando pontos de operação do sistema de armazenamento que maximizaram o aproveitamento dos recursos disponíveis. / This work proposes a method of energy management of a university campus, with a photovoltaic solar generation source and a energy storage system, which are connected to the main grid. The developed method aims to minimize the purchase of energy from the external grid using the Simulated Annealing optimization method. It is considered in the simulations variable energy tariffs according to the period of the day applied by the local utility. The obtained results were satisfactory, since the applied management scheme managed to reduce energy consumption significantly throughout the day, taking advantage of the energy stored at cheaper tariff schedules and greater availability of solar generation at peak times, making a minimum daily cost while it reaches the constraints associated with the problem. The obtained results showed the applicability of the optimization method, through the determination of operating points of the battery bank that maximized the use of available resources
