Abstract

Penggunaan energi terbarukan memiliki potensi besar untuk mengurangi ketergantungan pada pembangkit listrik konvensional, terutama di wilayah kepulauan Indonesia yang masih sangat bergantung pada pembangkit berbasis fosil. Pulau Buton, misalnya, memiliki potensi energi angin yang signifikan. Di Desa Rongi, Kabupaten Buton Selatan, tercatat kecepatan angin rata-rata sekitar 6 m/s. Dalam rangka mendukung target pemerintah Indonesia untuk mencapai bauran energi terbarukan pada tahun 2050, penelitian ini bertujuan untuk menganalisis dampak penetrasi turbin angin terhadap kualitas daya listrik di sistem distribusi Pulau Buton. Penetrasi turbin angin dalam skala besar diperkirakan dapat mempengaruhi kualitas daya dan stabilitas sistem secara keseluruhan. Oleh karena itu, penelitian ini berfokus pada analisis dampak penetrasi tersebut terhadap kualitas daya dan stabilitas sistem distribusi listrik di Pulau Buton. Simulasi aliran daya dan analisis transien dilakukan untuk menilai kinerja sistem dalam kondisi steady-state dan dinamis. Perangkat lunak ETAP versi 21.0.1 digunakan untuk membantu pemodelan dan simulasi. Skema penetrasi turbin angin yang dikaji melibatkan 7 unit turbin angin dengan kapasitas masing-masing 2,1 MW. Hasil penelitian menunjukkan bahwa pada kecepatan angin 4 m/s hingga 7 m/s, faktor daya dan tegangan pada setiap bus masih berada dalam batas operasi yang dapat diterima, dan rugi-rugi daya pada sistem mengalami penurunan. Namun, pada kecepatan angin 8 m/s dan 9 m/s, terjadi penurunan faktor daya dan tegangan, serta peningkatan rugi-rugi daya pada saluran. Analisis transien secara keseluruhan menunjukkan bahwa pada kecepatan angin 4 m/s, turbin angin belum stabil, sedangkan pada kecepatan angin 5 m/s hingga 7 m/s, tidak memberikan dampak yang signifikan. Sementara itu, pada kecepatan angin 8 m/s dan 9 m/s, terjadi penurunan frekuensi serta osilasi frekuensi, meskipun masih dalam batas sesuai standar. Pada kecepatan angin 7 m/s hingga 9 m/s, faktor daya mengalami penurunan, sehingga perlu dilakukan mitigasi

The use of renewable energy has great potential to reduce dependence on conventional power plants, especially in the Indonesian archipelago which is still highly dependent on fossil-based power plants. Buton Island, for example, has significant wind energy potential. In Rongi Village, South Buton Regency, the average wind speed is recorded at around 6 m/s. In order to support the Indonesian government's target to achieve a renewable energy mix by 2050, this study aims to analyze the impact of wind turbine penetration on the quality of electric power in the Buton Island distribution system. Large-scale wind turbine penetration is expected to affect the power quality and stability of the overall system. Therefore, this study focuses on analyzing the impact of this penetration on the power quality and stability of the electricity distribution system on Buton Island. Power flow simulation and transient analysis were conducted to assess the system performance under steady-state and dynamic conditions. ETAP software version 21.0.1 was used to assist in modeling and simulation. The wind turbine penetration scheme studied involved 7 wind turbine units with a capacity of 2.1 MW each. The results of the study showed that at wind speeds of 4 m/s to 7 m/s, the power factor and voltage at each bus were still within acceptable operating limits, and power losses in the system decreased. However, at wind speeds of 8 m/s and 9 m/s, there was a decrease in the power factor and voltage, as well as an increase in power losses in the line. The overall transient analysis showed that at a wind speed of 4 m/s, the wind turbine was not stable, while at wind speeds of 5 m/s to 7 m/s, it did not have a significant impact. Meanwhile, at wind speeds of 8 m/s and 9 m/s, there was a decrease in frequency and frequency oscillation, although still within the standard limits. At wind speeds of 7 m/s to 9 m/s, the power factor decreased, so mitigation was needed.
