Abstract

Energy Management Unit (EMU) dikembangkan untuk sistem daya hibrida yang mengintegrasikan Proton Exchange Membrane Fuel Cell (PEMFC), baterai litium-ion, superkapasitor 15.6 F, dan photovoltaic (PV) Trina Solar TSM-250PA05. EMU dirancang untuk mengatur distribusi daya secara efisien, mengurangi beban pada PEMFC, serta meningkatkan efisiensi dan keandalan operasional. Penggunaan sumber energi disesuaikan secara otomatis berdasarkan kondisi seperti state of charge (SOC) baterai, perubahan beban, dan ketersediaan energi dari PV. Superkapasitor digunakan untuk menangani lonjakan beban, mengoptimalkan konsumsi hidrogen, dan meningkatkan stabilitas daya. Dua algoritma pengaturan, yaitu Proportional Integral (PI) dan External Energy Management Strategy (EEMS), dibandingkan, dengan hasil yang menunjukkan bahwa EEMS lebih stabil dan efisien, mencapai efisiensi rata-rata 88,78%, sementara PI mencapai efisiensi 86,93%. Untuk meningkatkan performa, sistem kontrol EEMS disempurnakan dengan pendekatan Modified EEMS, yang memperbaiki respons terhadap variasi beban dengan mengurangi overshoot dan mempercepat waktu respons, mencapai efisiensi 89,05%. Penelitian ini dapat dikembangkan menjadi pembangkit listrik mini grid yang efisien untuk daerah-daerah terpencil yang belum terhubung dengan jaringan listrik.

An Energy Management Unit (EMU) has been developed for a hybrid power system that integrates Proton Exchange Membrane Fuel Cell (PEMFC), lithium-ion battery, 15.6 F supercapacitor, and Trina Solar TSM-250PA05 photovoltaic (PV). The EMU is designed to manage power distribution efficiently, reduce the load on the PEMFC, and enhance operational efficiency and reliability. The use of energy sources is automatically adjusted based on conditions such as the state of charge (SOC) of the battery, load changes, and PV energy availability. Supercapacitors are used to handle load surges, optimize hydrogen consumption, and improve power stability. Two control algorithms, Proportional Integral (PI) and External Energy Management Strategy (EEMS), are compared, with results showing that EEMS is more stable and efficient, achieving an average efficiency of 88.78%, while PI reaches 86.93%. To further enhance performance, the EEMS control system is improved with a Modified EEMS approach, which improves response to load variations by reducing overshoot and accelerating response time, achieving an efficiency of 89.05%. This research can be developed into an efficient mini-grid power generation system for remote areas not connected to the electrical grid.
