Abstract

Adopsi teknologi energi terbarukan yang terus berkembang masih menghadapi tantangan seperti ketidakstabilan, intermiten, dan kapasitas penyimpanan energi yang terbatas. Generator mesin diesel, yang dikenal dengan stabilitas dan keandalannya, tetap penting sebagai sumber daya utama atau cadangan, terutama di daerah terpencil. Namun, generator diesel konvensional yang beroperasi pada kecepatan konstan tidak efisien dalam konsumsi bahan bakar dan menghasilkan emisi yang tinggi. Penelitian ini menyelidiki implementasi sistem generator diesel berkecepatan variabel menggunakan generator BLDC (Brushless Direct Current) yang dikontrol oleh pengontrol berbasis logika fuzzy (FLC). Sistem yang diusulkan menyesuaikan kecepatan mesin dan siklus kerja konverter untuk mengoptimalkan efisiensi bahan bakar dengan tetap menjaga kestabilan tegangan dan frekuensi. Hasil simulasi menunjukkan bahwa sistem ini mengurangi konsumsi bahan bakar hingga 7,6% (0,86 liter/jam) untuk generator 100 kW. Selain itu, FLC secara efektif menstabilkan tegangan dan frekuensi selama perubahan beban dan akhirnya meningkatkan kinerja sistem secara keseluruhan

The growing adoption of renewable energy technologies still faces challenges such as instability, intermittency, and limited energy storage capacity. Diesel engine generators, known for their stability and reliability, remain important as primary or backup power sources, especially in remote areas. However, conventional diesel generators operating at constant speed are inefficient in fuel consumption and produce high emissions. This study investigates the implementation of a variable-speed diesel generator system using a BLDC (Brushless Direct Current) generator controlled by a fuzzy logic controller (FLC). The proposed system adjusts the engine speed and converter duty cycle to optimize fuel efficiency while maintaining voltage and frequency stability. Simulation results show that this system reduces fuel consumption by up to 7.6% (0.86 liters/hour) for a 100 kW generator. Furthermore, the FLC effectively stabilizes voltage and frequency during load changes and ultimately improves overall system performance
