Abstract
Keandalan merupakan aspek penting dalam sistem tenaga listrik yang berpengaruh terhadap kontinuitas pasokan dan kualitas pelayanan. Evaluasi keandalan dapat dilakukan menggunakan indeks Loss of Load Probability (LOLP) yang menggambarkan probabilitas terjadinya defisit daya, serta Loss of Load Expectation (LOLE) yang menunjukkan ekspektasi jumlah hari dalam setahun ketika sistem tidak mampu memenuhi beban. Penelitian ini menganalisis keandalan sistem isolated Ketapang di Kalimantan Barat dengan menggunakan metode rekursif. Sistem Ketapang saat ini disuplai oleh 19 unit pembangkit dengan total kapasitas 50,6 MW dengan beban puncak tertinggi tahun 2023 mencapai 44,27 MW. Hasil analisis menunjukkan nilai LOLP sebesar 0,01992 dan LOLE sekitar 7,27 hari/tahun, yang mengindikasikan potensi terjadinya kekurangan daya cukup signifikan. Untuk meningkatkan keandalan, dilakukan integrasi Pembangkit Listrik Tenaga Biomassa (PLTBm) yang memanfaatkan limbah kelapa sawit dengan kapasitas 12,05 MW. Hasilnya dapat menurunkan nilai LOLP dan LOLE sebesar 88% menjadi 0,00238 dan 0,87 hari/tahun. Skenario integrasi PLTBm dengan penyesuaian OLTC mampu meningkatkan performa sistem Kelistrikan Ketapang, karena dapat menjaga profil tegangan tetap berada dalam rentang standar, menghasilkan kebutuhan daya reaktif (Mvar) yang lebih kecil dibandingkan kondisi aktual, serta menurunkan rugi-rugi daya apabila dibandingkan dengan skenario yang hanya menambahkan PLTBm tanpa penyesuaian OLTC.

Reliability is a crucial aspect of the power system that impacts the continuity of supply and quality of service. Reliability evaluation can be conducted using the Loss of Load Probability (LOLP) index, which represents the probability of a power deficit occurring, and the Loss of Load Expectation (LOLE) index, which indicates the expected number of days per year when the system is unable to meet the load. This study analyzes the reliability of the Ketapang isolated system in West Kalimantan using the recursive method. The Ketapang system is currently supplied by 19 generating units with a total capacity of 50,6 MW, and the highest peak load in 2023 reached 44,27 MW. The analysis results show a LOLP value of 0,01992 and a LOLE of approximately 7,27 days per year, which indicates a significant potential for power shortages. To improve reliability, a Biomass Power Plant (BPP) utilizing palm oil waste with a capacity of 12,05 MW was integrated into the system. As a result, the LOLP and LOLE values decreased by 88% to 0,00238 and 0,87 days per year, respectively. The BPP integration scenario with OLTC adjustments is able to improve the performance of the Ketapang Electricity system, because it can maintain the voltage profile within the standard range, produce smaller reactive power (Mvar) requirements compared to actual conditions, and reduce power losses when compared to the scenario that only integration BPP without OLTC adjustments.
