Abstract

Sistem kelistrikan Sumbawa – Bima membentang dari Labuhan (Sumbawa) sampai ke Dompu (Bima). Jaringan yang meliputi pada sistem ini meliputi tegangan 150 Kv dan 70 Kv. Sistem ini dipasok dari PLTU, PLTMG, PLTD, dan PLTM/PLTMH. Menurut Rencana Usaha Penyediaan Tenaga Listrik (RUPTL) saat ini produksi tenaga Listrik pada sistem kelistrikan di Nusa Tenggara Barat (NTB) Sebagian masih diperoleh dari PLTD sehingga mengakibatkan biaya pokok produksi masih cukup tinggi. Sistem kelistrikan Sumbawa memiliki potensi PLTS yang ditargetkan untuk mengurangi biaya pokok produksi. Dengan maraknya penggunaan energi baru terbarukan pada sistem kelistrikan menyebabkan permasalahan tersendiri pada jaringan kelistrikan. Salah satu factor penting pada sistem kelistrikan adalah kestabilan pada sistem tenaga Listrik. Penambahan PLTS pada sistem kelistrikan dapat mempengaruhi kestabilan pada sistem, khususnya saat terjadi gangguan hubung singkat tiga fasa. Penelitian ini bertujuan untuk menganalisis pengaruh penetrasi PLTS terhadap kestabilan transien sistem kelistrikan Sumbawa menggunakan simulasi pada software DigSilent PowerFactory. Tiga skenario dibandingkan, yaitu sistem tanpa PLTS, sistem dengan PLTS kontrol droop, dan sistem dengan PLTS kontrol fixed output. Parameter yang dianalisis meliputi respons tegangan, frekuensi, sudut rotor, daya pembangkit sinkron, dan daya keluaran PLTS. Hasil simulasi menunjukkan bahwa PLTS dengan kontrol droop memberikan kontribusi positif terhadap kestabilan sistem. PLTS jenis ini mampu memberikan fast frequency response, menekan lonjakan daya puncak generator slack, mempercepat redaman ayunan rotor, serta menyeimbangkan daya aktif dengan respons yang adaptif. Sebaliknya, PLTS dengan kontrol fixed output tidak memberikan respons terhadap gangguan, sehingga membebani pembangkit konvensional lebih berat dan menghasilkan deviasi parameter sistem yang lebih besar. Dengan demikian, integrasi PLTS dengan kontrol droop terbukti lebih efektif dalam menjaga kestabilan transien pada sistem isolated seperti Sumbawa.

The Sumbawa–Bima power system extends from Labuhan (Sumbawa) to Dompu (Bima), comprising 150 kV and 70 kV transmission networks. This system is supplied by coal-fired power plants (PLTU), gas engine power plants (PLTMG), diesel generators (PLTD), and micro/mini-hydro power plants (PLTM/PLTMH). According to the Electricity Supply Business Plan (RUPTL), a significant portion of electricity production in the West Nusa Tenggara (NTB) region still relies on PLTD, resulting in a relatively high cost of electricity generation. The Sumbawa power system has solar photovoltaic (PV) potential, which is targeted to reduce production costs. However, the increasing use of renewable energy sources in power systems presents new challenges, particularly regarding the stability of the electricity network. One of the most critical aspects of a power system is the stability of the electrical grid itself. The addition of PV to the power system can affect its stability, especially during three-phase short-circuit disturbances. This study aims to analyze the impact of PV penetration on the transient stability of the Sumbawa power system using simulations conducted in DigSilent PowerFactory software. Three scenarios are compared: the system without PV, the system with PV using droop control, and the system with PV using fixed output control. The parameters analyzed include voltage response, frequency response, rotor angle, synchronous generator output, and PV output power. The simulation results show that PV systems with droop control contribute positively to system stability. This type of PV is capable of providing fast frequency response, reducing the peak power overshoot in the slack generator, accelerating rotor angle damping, and balancing active power through adaptive response. In contrast, PV systems with fixed output control do not respond to disturbances, which increases the burden on conventional generators and leads to greater deviations in system parameters. Therefore, the integration of PV with droop control proves to be more effective in maintaining transient stability in isolated power systems such as that of Sumbawa.
