Abstract

Peningkatan kebutuhan energi listrik serta rencana integrasi Pembangkit Listrik Tenaga Surya (PLTS) dalam sistem kelistrikan Pulau Bawean menimbulkan tantangan terhadap kestabilan tegangan, terutama karena karakteristik sistem yang terisolasi dan memiliki margin stabilitas yang terbatas. Penetrasi PLTS yang bersifat intermiten berpotensi meningkatkan risiko terjadinya voltage collapse akibat berkurangnya kemampuan sistem dalam mempertahankan profil tegangan saat terjadi peningkatan beban. Penelitian ini bertujuan untuk menganalisis pengaruh integrasi Battery Energy Storage System (BESS) terhadap peningkatan kestabilan tegangan dan kemampuan pembebanan maksimum (maximum loadability) pada sistem kelistrikan Pulau Bawean. Analisis dilakukan menggunakan perangkat lunak DIgSILENT PowerFactory dengan metode load flow, kurva P–V, dan kurva Q–V pada kondisi tahun 2025, 2028, dan 2034. Simulasi dilakukan pada kondisi tanpa BESS (base case) serta dengan integrasi BESS pada faktor daya 1,0 dan 0,85. Hasil penelitian menunjukkan bahwa integrasi BESS mampu meningkatkan margin kestabilan tegangan pada seluruh bus kritis yang dianalisis. Peningkatan kemampuan pembebanan maksimum terbesar terjadi pada Bus G(3) Feeder Kota, sementara peningkatan margin daya reaktif terbesar terjadi pada Bus S(1) Feeder Sangkapura. Selain itu, manfaat BESS semakin meningkat seiring pertumbuhan beban dan penetrasi energi terbarukan, dengan peningkatan maximum loadability mencapai lebih dari 2% pada tahun 2034. Dari seluruh skenario yang dianalisis, operasi BESS pada faktor daya 0,85 memberikan performa terbaik karena mampu menyediakan dukungan daya reaktif yang lebih besar sehingga meningkatkan kemampuan sistem dalam menunda terjadinya voltage collapse. Hasil penelitian ini menunjukkan bahwa BESS merupakan solusi yang efektif untuk meningkatkan keandalan dan kestabilan tegangan sistem kelistrikan Pulau Bawean pada masa mendatang.

The increasing demand for electrical energy and the planned integration of photovoltaic (PV) power plants into the Bawean Island power system pose significant challenges to voltage stability, particularly due to the isolated nature of the system and its limited stability margin. The intermittent characteristics of PV generation may increase the risk of voltage collapse by reducing the system's capability to maintain acceptable voltage profiles under increasing load conditions. This study aims to analyze the impact of Battery Energy Storage System (BESS) integration on voltage stability enhancement and maximum loadability improvement in the Bawean power system. The analysis was conducted using DIgSILENT PowerFactory through load flow studies, P–V curve analysis, and Q–V curve analysis for the years 2025, 2028, and 2034. Simulations were performed under both base-case conditions and BESS integration scenarios with power factors of 1.0 and 0.85. The results indicate that BESS integration improves the voltage stability margin at all critical buses investigated. The highest increase in maximum loadability was observed at Bus G(3) of Kota Feeder, while the largest improvement in reactive power margin occurred at Bus S(1) of Sangkapura Feeder. Furthermore, the benefits of BESS become more significant as load demand and renewable energy penetration increase, with maximum loadability improvements exceeding 2% in 2034. Among all analyzed scenarios, BESS operation at a power factor of 0.85 demonstrated the best performance by providing greater reactive power support and enhancing the system's capability to delay voltage collapse. The findings confirm that BESS is an effective solution for improving the reliability and voltage stability of the Bawean Island power system in the future.
