Abstract

Integrasi Pembangkit Listrik Tenaga Surya (PLTS) dan Battery Energy Storage System (BESS) pada sistem kelistrikan Lombok terus meningkat sebagai bentuk transisi menuju energi bersih, namun variabilitas daya keluaran PLTS berpotensi memicu ketidakstabilan sudut rotor pada generator sinkron. Kondisi ini dapat menyebabkan pelebaran deviasi sudut rotor, penurunan margin stabilitas, hingga meningkatkan risiko loss of synchronism ketika terjadi gangguan besar. Penelitian ini bertujuan untuk menganalisis pengaruh peningkatan penetrasi PLTS dan BESS terhadap kestabilan sudut rotor pada sistem kelistrikan Lombok serta mengevaluasi penggunaan sistem penyimpanan energi BESS sebagai peredam osilasi sudut rotor. Model sistem dirancang menggunakan DigSILENT PowerFactory 21 dengan data pembangkit, jaringan, dan beban aktual sistem existing. Skenario simulasi dilakukan dengan beberapa kondisi existing, kondisi existing terintegrasi PLTS, serta kondisi existing terintegrasi PLTS dan BESS. Parameter kestabilan dianalisis melalui respon sudut rotor selama kondisi gangguan hubung singkat 3 fasa. Hasil penelitian diharapkan mampu memberikan pemahaman mengenai dampak penetrasi PLTS dan BESS terhadap kestabilan sudut rotor agar tidak kehilangan sinkronisasi, serta efektivitas BESS dalam meningkatkan rotor angle stability melalui injeksi daya aktif yang cepat dan adaptif. Temuan ini dapat menjadi dasar perencanaan pengembangan energi terbarukan yang lebih aman dan stabil di masa mendatang.

The integration of Solar Power Plants (PV) and Battery Energy Storage Systems (BESS) into the Lombok power system has been increasing as part of the transition toward renewable energy; however, the variability of PV output power may negatively affect rotor angle stability in synchronous generators, leading to larger rotor angle deviations, reduced stability margins, and an increased risk of loss of synchronism during severe disturbances. Therefore, this study aims to analyze the impact of increasing PV and BESS penetration levels on rotor angle stability and to evaluate the effectiveness of BESS in damping rotor angle oscillations. The power system model was developed in DigSILENT PowerFactory 21 using actual generation, network, and load data of the existing Lombok power system. Simulation scenarios were conducted under three operating conditions, namely the existing system, the existing system integrated with PV, and the existing system integrated with both PV and BESS. Rotor angle stability was assessed based on the dynamic response of generators under three-phase short-circuit fault conditions. The results are expected to provide a better understanding of the influence of PV and BESS integration on rotor angle stability and their capability to prevent loss of synchronism, while also demonstrating the effectiveness of BESS in enhancing transient stability through fast and adaptive active power injection. These findings may serve as a valuable reference for the secure and reliable integration of renewable energy resources in future power systems.
