Abstract
Perpaduan energi terbarukan ke dalam sistem kelistrikan terisolasi memerlukan perencanaan yang cermat agar keandalan dan efisiensi biaya tetap terjaga. Penelitian ini mengkaji perencanaan penyimpanan energi pada sistem kelistrikan Pulau Selayar, yang saat ini mengandalkan pembangkit diesel dan satu unit pembangkit surya. Penjadwalan operasi pembangkit dilakukan menggunakan metode Mixed Integer Linear Programming (MILP) untuk periode 24 jam, sementara kapasitas optimal sistem penyimpanan energi ditentukan dengan Algoritma Firefly. Simulasi dilakukan dalam tiga kondisi, yaitu simulasi dengan pembangkit, selanjutnya simulasi dengan PLTS tanpa penyimpanan dan ketiga dengan menghubungkan sistem Battery Energy Storage System. Hasil menunjukkan bahwa penggunaan BESS membantu menstabilkan distribusi daya, terutama saat beban puncak, serta mengurangi fluktuasi daya keluaran dari pembangkit. Selain itu, penerapan BESS diharapkan dapat menurunkan total biaya pembangkitan sebesar 0.25 persen dibandingkan dengan kondisi tanpa penyimpanan. Percobaan ini mendapatkan bahwa penggabungan metode MILP dan Algoritma Firefly mampu meningkatkan efisiensi operasional serta optimalisasi biaya pada sistem kelistrikan daerah terpencil meskipun kecil.

The integration of renewable energy into isolated power systems requires careful planning to ensure both reliability and cost efficiency. This study focuses on energy storage planning for the Selayar Island power system, which currently relies on diesel generators and a single solar power unit. Generation scheduling is carried out using the Mixed Integer Linear Programming (MILP) method over a 24-hour period, while the optimal capacity of the energy storage system is determined using the Firefly Algorithm. Simulations were conducted under three scenarios namely operation with diesel generators only, with the addition of solar PV without storage, and finally, with the integration of a Battery Energy Storage System (BESS). The results indicate that BESS contributes to stabilizing power distribution especially during peak load periods and helps mitigate output fluctuations from generation units. Moreover, the application of BESS is expected to reduce total generation costs by approximately 0.25% compared to systems without storage. This experiment demonstrates that the combined use of MILP and the Firefly Algorithm can enhance operational efficiency and cost optimization in remote power systems, even if the improvement is relatively modest.
