Abstract

PLTN merupakan pembangkit rendah emisi yang menjadi salah satu alternatif untuk mencapai tujuan net zero emission di Indonesia, khususnya di Kalimantan Barat. Pada penelitian ini akan dibahas mengenai perencanaan implementasi PLTN pada Sistem Tenaga Listrik Kalbar di tahun 2030. Fokus topik utama dalam penelitian ini adalah untuk memberikan informasi serta wawasan akan potensi terjadinya fenomena power swing di sistem tenaga listrik Kalbar akibat operasional smelter dan intermittency PLTS. Selain itu, penelitian ini bertujuan untuk menginvestigasi kemampuan kapabilitas dari pembangkit PLTN dan sistem transmisi Kalbar dalam menghadapi fenomena power swing akibat smelter dan PLTS. PLTN dapat dikatakan fleksibel karena merupakan pembangkit yang mampu beroperasi pada mode base load dan load follower. Pelaksanaan penelitian ini dilakukan dengan menggunakan perangkat lunak ETAP 22.0.1 untuk melakukan simulasi dinamis menggunakan studi stabilitas transient. Hasil dari penelitian ini meninjau dampak dari fluktuasi beban smelter dan keadaan intermittency penetrasi dari PLTS terhadap perubahan nilai frekuensi, daya aktif dan sudut rotor pembangkit. Saat PLTN belum dioperasikan, pembangkit eksisting mengalami fenomena power swing yang berkepanjangan. Hal ini dibuktikan dari grafik dan rata-rata nilai rasio redaman yang berkisar di antara 5%-30%. Pada mode operasi base load, PLTN tidak menunjukkan fenomena power swing dan memiliki rata-rata rasio redaman sebesar 70%. PLTN pada mode load follower dapat melakukan penyesuain daya dengan kapabilitas perubahan daya mencapai 80% dari total kapasitas maksimumnya. PLTN pada tiap mode operasi mampu meredam osilasi akibat power swing hingga 90%. Nilai ini diukur dari karakteristik rasio redaman tiap pembangkit yang mengalami kenaikan setelah PLTN mulai dioperasikan secara bersamaan dengan pembangkit lain. Dengan kata lain, PLTN mampu menjaga dan meningkatkan kestabilan sistem tenaga listrik Kalbar akibat power swing yang disebabkan oleh smelter dan PLTS.

System by 2030. The primary focus of this study is to provide information and insights into the potential occurrence of power swing phenomena in the Kalbar power system due to smelter operations and PV intermittency. Additionally, this research aims to investigate the capability and flexibility of NPP in addressing power swing phenomena caused by smelters and PV. NPP can be considered flexible as they can operate in both base load and load follower modes. The research was conducted using ETAP 22.0.1 software to perform dynamic simulations using transient stability studies. The results of this research examine the impact of smelter load fluctuations and PV penetration intermittency on changes in frequency values, active power, and generator rotor angle. When NPP were not yet in operation, existing generators experienced prolonged power swing phenomena. This is evidenced by the graphs and average damping ratio values ranging between 5% and 30%. In base load operation mode, NPP do not exhibit power swing phenomena and have an average damping ratio of 70%. NPP in load follower mode can adjust power with a power change capability of up to 80% of their total maximum capacity. PLTNs in each operating mode can damp oscillations due to power swing by up to 90%. This value is measured from the damping ratio characteristics of each generator, which increase after PLTNs are put into operation together with other generators. In other words, PLTNs can maintain and improve the stability of the Kalbar power system against power swings caused by smelters and PLTS.
