Abstract

Penelitian ini mengembangkan sistem daya hibrida berbasis fuel cell, baterai, superkapasitor, dan panel surya, dengan fokus pada manajemen energi menggunakan algoritma kontrol External Energy Maximization Strategy (EEMS). Sistem ini dirancang untuk memenuhi kebutuhan beban resistif DC dengan mengoptimalkan keluaran daya baterai serta pengaturan tegangan charge/discharge superkapasitor. Input utama algoritma EEMS adalah state of charge (SOC) baterai dan tegangan DC bus. Pada penelitian ini digunakan tiga variasi SOC awal baterai. Performansi EEMS berfokus pada penghematan hidrogen, SOC baterei, dan efisiensi sistem. Hasil pengujian menunjukkan bahwa algoritma kontrol EEMS yang dirancang mampu mendistribusikan daya dari masing-masing komponen sistem daya hibrida dan peningkatan nilai SOC awal baterai berdampak positif terhadap efisiensi sistem dan konsumsi hidrogen. Pada SOC awal 60%, 70%, dan 80%, efisiensi sistem masing-masing tercatat sebesar 87,68%, 87,76%, dan 87,83%, sementara konsumsi hidrogen menurun dari 39,92 gram, 36,58 gram dan 35,21 gram. Peningkatan SOC awal baterai juga menyebabkan penggunaan daya baterai lebih banyak untuk pemenuhan kebutuhan beban.

This study developed a hybrid power system based on fuel cells, batteries, supercapacitors, and solar panels, focusing on energy management using the External Energy Maximization Strategy (EEMS) control algorithm. The system was designed to meet the demands of DC resistive loads by optimizing battery power output and managing the charge/discharge voltage of the supercapacitor. The main inputs for the EEMS algorithm are the state of charge (SOC) of the battery and the DC bus voltage. Three variations of the initial SOC of the battery were used in this study. The performance of EEMS was evaluated based on hydrogen savings, battery SOC, and system efficiency. The test results indicate that the designed EEMS control algorithm effectively distributes power from each component of the hybrid power system. Additionally, increasing the initial SOC of the battery positively impacts system efficiency and hydrogen consumption. At initial SOCs of 60%, 70%, and 80%, the system efficiencies were recorded at 87.68%, 87.76%, and 87.83%, respectively, while hydrogen consumption decreased from 39.92 grams to 36.58 grams and 35.21 grams. Higher initial SOC also leads to greater battery power usage to meet load demands.
