Abstract

Menurut Rencana Usaha Penyediaan Tenaga Listrik (RUPTL) draft 2021 – 2030, terdapat rencana pembangunan Pembangkit Listrik Tenaga Surya (PLTS) berkapasitas 3,2 MW di Pulau Rote pada tahun 2025. Pembangunan PLTS pada Pulau Rote tidak hanya bertujuan untuk mengurangi emisi karbon, tetapi juga untuk menekan biaya operasional yang tinggi untuk Pembangkit Listrik Tenaga Diesel (PLTD). Dalam mengintegrasikan PLTS ke sistem, diperlukan pemilihan lokasi yang tepat untuk meminimalisir kerugian pada sistem. Salah satu aspek yang perlu diperhatikan adalah stabilitas tegangan. Pada penelitian ini, akan dilakukan studi untuk menentukkan lokasi penempatan PLTS pada pulau Rote terlebih dahulu. Selain PLTS, Battery Energy Storage System (BESS) juga diintegrasikan ke dalam sistem untuk mengantisipasi beban puncak Pulau Rote yang terjadi pada malam hari. Penentuan lokasi PLTS dan BESS pada sistem akan dilakukan berdasarkan metode sensitivitas tegangan. Berdasarkan sensitivitas tegangan terbesar, lokasi penempatan PLTS dan BESS pada sistem distribusi Pulau Rote akan ditempatkan pada feeder Busalangga dan feeder Papela. Penentuan lokasi dibagi menjadi 2 skema, yaitu skema PLTS terpusat dan PLTS tersebar. Setelah penentuan lokasi PLTS dan BESS, dilakukan simulasi stabilitas tegangan saat kondisi steady-state menggunakan p-v curve. Hasil simulasi menunjukkan batasan transfer daya sebelum menuju titik collapse (voltage collapse) pada seluruh bus sistem Pulau Rote mengalami kenaikan, seperti pada bus 503 feeder Busalangga dari 4,983 MW saat kondisi existing menjadi 6,904 MW saat kondisi PLTS terpusat dan 6,848 MW saat kondisi PLTS tersebar. Melalui simulasi p-v curve pada 334 bus, didapat skema PLTS tersebar membuat batas transfer daya pada bus sistem lebih besar dibanding skema PLTS terpusat. Adanya penambahan PLTS dan BESS pada sistem Pulau Rote juga menaikkan voltage profile pada setiap bus yang dianalisis menggunakan simulasi quasi-dynamic selama 24 jam, seperti pada bus 503 feeder Busalangga dengan tegangan existing 0,9271 p.u. naik menjadi 0,9613 p.u. pada skema PLTS terpusat dan 0,9612 p.u. pada skema PLTS tersebar saat beban kondisi beban puncak.

According to the National Electricity Supply Business Plan (RUPTL) for 2021–2030, there is a plan to construct a 3,2 MW solar power plant on Rote Island by 2025. The objective of building the solar power plant on Rote Island is not only to reduce carbon emissions but also to lower the high operational costs associated with the diesel power plant. To integrate the solar power plant into the system effectively, it is crucial to select an appropriate location to minimize system losses. One key aspect to consider is voltage stability. This study will first determine the optimal location for placing the solar power plant on Rote Island. Besides the solar power plant, a Battery Energy Storage System (BESS) will also be integrated into the system to manage peak loads occurring at night on Rote Island. The location determination for the solar power plant and BESS will be based on the voltage sensitivity method. Based on the highest voltage sensitivity, the solar power plant and BESS will be placed on the Busalangga feeder and Papela feeder. The study examines two scenarios: a centralized solar power plant and a distributed solar power plant. After determining the locations for the solar power plant and BESS, voltage stability simulations in steady-state conditions will be conducted using the p-v curve. The simulation results show that the power transfer limits before reaching the collapse point (voltage collapse) in all buses of the Rote Island system have increased, as seen at bus 503 of the Busalangga feeder, from 4,983 MW in the existing condition to 6,904 MW in the centralized solar power plant condition and 6,848 MW in the distributed solar power plant condition. Through p-v curve simulations on 334 buses, it was found that the distributed solar power plant scheme results in higher power transfer limits on the system buses compared to the centralized solar power plant scheme. The addition of solar power plant and BESS to the Rote Island system also raises the voltage profile at each bus analyzed using quasi-dynamic simulations over 24 hours, as seen at bus 503 of the Busalangga feeder, where the existing voltage of 0,9271 p.u. increased to 0,9613 p.u. in the centralized solar power plant scheme and 0,9612 p.u. in the distributed solar power plant scheme during peak load condition.
