Abstract

Mengingat keterbatas energi fosil, Indonesia secara perlahan sudah mememulai transisi mengarah pada energi terbarukan. Indonesia merupakan salah satu negara tropis dengan sinar matahari sepanjang tahun hal ini tentu menjadi potensi pengembangan pembangkitan tenaga surya. Dalam upaya mengembakang potensi tersebut pemerintah Indonesia sudah berkomitmen untuk melakukan transisi energi baru terbarukan melalui Rencana Umum Energi Nasional (RUEN) dan menargetkan penerapan Renewable Energy Technologies (RET) 23% dari total pembagian energi utama dan 31% pada tahun 2050. Pulau Lombok sebagai salah satu pulau yang ada di Nusa Tenggara Barat, PLTS menjadi salah satu solusi yang di tawarkan hal ini juga sejalan dengan kebijakan pemerintah dalam meningkatkan pemanfaatan pembangkitan Energi Baru Terbarukan (EBT). Oleh karena itu pada tugas akhir ini akan dilakukan permodelan PLTS dan dianalisis dampak penetrasi PLTS tehadap stabilitas, khususnya melalui pengamatan terhadap nilai Critical Clearing Time (CCT) mengunakan software DIgsilent PowerFactory. Simulasi dilakukan dengan skenario gangguan hubung singkat pada saluran 150kV baik pada kondisi beban puncak siang maupun luar beban puncak siang. Hasil simulasi menunjukkan bahwa penetrasi PLTS dapat memengaruhi nilai CCT pada sistem. Pada saluran Jeranjang Sengkol, nilai CCT meningkat seiring dengan peningkatan penetrasi PLTS, sedangkan pada saluran Bayan–Sambelia, nilai CCT menurun. Hal ini menunjukkan bahwa penetrasi PLTS tidak selalu memberikan dampak positif terhadap nilai CCT pada sistem kelistrikan Pulau Lombok.

Considering the limitations of fossil energy, Indonesia is gradually transitioning towards renewable energy. As a tropical country with year-round sunlight, Indonesia has great potential for solar power generation. In an effort to develop this potential, the Indonesian government has committed to transitioning to renewable energy through the National General Energy Plan (RUEN), aiming for the application of Renewable Energy Technologies (RET) to contribute 23% of the total primary energy mix and 31% by 2050. Lombok Island, as one of the islands in West Nusa Tenggara, solar power plants as one of the proposed solutions, which aligns with the government’s policy to increase the use of renewable energy generation. Therefore, this thesis will model the solar power plants and analyze the impact of solar power plants penetration on stability, particularly by observing the Critical Clearing Time (CCT) using the DIgSILENT PowerFactory software. Simulations were conducted with short-circuit fault scenarios on the 150 kV transmission lines, both during peak daytime load conditions and offpeak daytime load conditions. The simulation results show that solar power plants penetration can affect the CCT value in the system. On the Jeranjang–Sengkol transmission line, the CCT increases as solar power plants penetration rises, whereas on the Bayan–Sambelia transmission line, the CCT decreases. This indicates that solar power plants penetration does not always have a positive impact on the CCT in the Lombok Island power system.
