Abstract

Komitmen Indonesia terhadap target net-zero emission 2060 dan arah kebijakan RUPTL 2025–2034 mendorong peningkatan penetrasi energi terbarukan pada sistem kelistrikan kepulauan seperti Ambon–Seram. Pada sistem yang relatif lemah, integrasi Pembangkit Listrik Tenaga Surya (PLTS) skala besar dan Battery Energy Storage System (BESS) berpotensi memengaruhi kestabilan tegangan dalam kondisi tunak. Penelitian ini menganalisis dampak integrasi terkoordinasi PLTS dan BESS terhadap stabilitas tegangan Sistem Kelistrikan Ambon–Seram untuk tahun perencanaan 2033. Model sistem dikembangkan di perangkat lunak DIgSILENT PowerFactory berdasarkan data operasi dan rencana pengembangan pembangkit, termasuk proyeksi pertumbuhan beban, komposisi pembangkitan, serta lokasi kandidat PLTS dan BESS. Stabilitas tegangan dievaluasi menggunakan studi aliran daya, analisis kurva P–V, serta indeks stabilitas tegangan pada bus-bus kritis pada kondisi beban puncak. Beberapa skenario disimulasikan, meliputi sistem dasar tahun 2033 tanpa PLTS/BESS, penambahan PLTS saja, serta kombinasi PLTS dan BESS dengan variasi kapasitas, lokasi, dan pengaturan daya reaktif inverter. Hasil studi diharapkan dapat memberikan rekomendasi teknis penempatan dan kapasitas PLTS–BESS yang mampu meningkatkan cadangan stabilitas tegangan sekaligus mendukung penetrasi PLTS yang lebih tinggi di Sistem Ambon–Seram.

Indonesia’s commitment to a net-zero emission target by 2060 and the policy direction of the RUPTL 2025–2034 encourage increasing penetration of renewable energy in islanded power systems such as Ambon–Seram. In such relatively weak grids, the integration of large-scale solar photovoltaic (PV) power plants and battery energy storage systems (BESS) can significantly affect steady-state voltage stability. This study analyzes the impact of coordinated PV and BESS integration on the voltage stability of the Ambon–Seram power system for the 2033 planning year. The system model is developed in DIgSILENT PowerFactory based on operational data and generation expansion plans, including projected load growth, generation mix, and candidate locations for PV and BESS. Voltage stability is evaluated using load-flow studies, P–V curve analysis, and a voltage stability index at critical buses under peak load conditions. Several scenarios are simulated, including the 2033 base system without PV/BESS, PV-only integration, and combined PV and BESS integration with different capacities, locations, and inverter reactive power settings. The results are expected to provide technical recommendations for the siting and sizing of PV–BESS that can enhance the voltage stability margin while supporting higher PV penetration in the Ambon–Seram power system.
