Análise de sistema híbrido de geração de energia no IFMG Campus Formiga

This Course Conclusion Paper (TCC) analyzed the performance of a grid-connected hybrid photovoltaic system installed in the carport structure located at the Federal Institute of Education, Science and Technology of Minas Gerais (IFMG) – Formiga Campus. The system is composed of 15 SUNOVA SS-585-72MDH(T) photovoltaic modules, a Huawei SUN2000-6KTL-L1 hybrid inverter, a Huawei LUNA2000-5-S0 battery, and a Terra AC W7-G5-R-0 electric vehicle charger. The objective was to evaluate the energy behavior of the system in four inverter operating modes. The four analyzed modes were: Maximum Self-Consumption, Feed-in Priority, Third-Party Control, and Time of Use (ToU). In the Maximum Self-Consumption mode, the generated energy is primarily used to supply local loads. In the Feed-in Priority mode, greater export of electricity to the utility grid was observed. In the Third-Party Control mode, the charging and discharging of the battery are managed by an external control platform, which is not present at the campus, resulting in the battery operating without active charge management. In the ToU mode, the system was programmed to charge the battery in the morning and discharge it at night, demonstrating time-based energy management capability. Additionally, operational recommendations were proposed for the electric vehicle charger, emphasizing charging through photovoltaic generation or stored battery energy, thus avoiding the use of electricity from the institutional grid and ensuring compliance with the campus’s energy use policies. The analyzed hybrid system demonstrated operational flexibility across its four modes, optimizing the use of the energy produced. Therefore, the integration between photovoltaic generation and energy storage highlights the relevance of this type of system as a sustainable alternative for public institutions and reinforces its educational value for students at the campus.
