Abstract

Penggunaan energi terbarukan dalam pembangkit listrik telah menjadi prioritas strategis global untuk rencana energi jangka menengah dan panjang, didorong oleh meningkatnya kebutuhan energi dan kesadaran dampak lingkungan dari bahan bakar fosil. Tantangan utama berupa intermittensi dan ketergantungan kondisi cuaca diatasi melalui implementasi Hybrid Renewable Energy System (HRES) yang mengintegrasikan berbagai sumber energi terbarukan dengan teknologi penyimpanan energi. Penelitian ini bertujuan merancang pola operasi optimal untuk meminimalkan biaya pengoperasian sistem hibrida pada Renewable Energy Integration Demonstrator of Indonesia (REIDI) menggunakan optimasi PYOMO. Sistem terintegrasi meliputi pembangkit listrik tenaga surya, sistem penyimpanan baterai (LFP dan VRLA), sistem penyimpanan hidrogen (HESS), pembangkit biomassa, diesel generator, dan koneksi jaringan PLN. REIDI difungsikan sebagai pembangkit tenaga listrik yang menyuplai kebutuhan beban di Institut Teknologi Sepuluh Nopember (ITS) sekaligus sebagai laboratorium untuk menyimulasikan kondisi-kondisi kelistrikan hibrida baik dalam mode on-grid maupun off-grid. Untuk fungsi sebagai pembangkit, energi yang dihasilkan REIDI sebesar 3.925,69 kWh per hari dengan biaya operasional Rp 1.220.109,61 dan keuntungan Rp 4.334.738,58 tanpa memperhitungkan investasi. Jika memperhitungkan investasi, keuntungan turun menjadi Rp 1.139.261,85. Untuk pemanfaatan sebagai laboratorium dengan profil beban 4.786 kWh per hari, optimasi dilakukan pada empat skenario yaitu on-grid normal operasi, on-grid dengan pembatasan jaringan, off-grid baterai grid forming, dan off-grid diesel grid forming. Hasil penelitian menunjukkan skenario on-grid normal operasi mencapai efisiensi ekonomi tertinggi dengan biaya operasional Rp 6.905.072,15. Sistem PV menunjukkan konsistensi pemanfaatan 100% di seluruh skenario, sementara biomassa terbukti ekonomis sebagai baseload dengan biaya Rp 1.065,39 per kWh. Konfigurasi off-grid mengalami peningkatan biaya signifikan hampir satu setengah kali, mengonfirmasi trade-off fundamental antara efisiensi ekonomi dan kemandirian energi.

The utilization of renewable energy in power generation has become a global strategic priority for medium and long-term energy planning, driven by increasing energy demands and environmental awareness of fossil fuel impacts. The main challenges of intermittency and weather dependency are addressed through the implementation of Hybrid Renewable Energy System (HRES) that integrates various renewable energy sources with energy storage technologies. This research aims to design optimal operational patterns to minimize operating costs of hybrid systems at the Renewable Energy Integration Demonstrator of Indonesia (REIDI) using PYOMO optimization. The integrated system includes solar photovoltaic power plant, battery storage systems (LFP and VRLA), hydrogen energy storage system (HESS), biomass generator, diesel generator, and PLN grid connection. REIDI functions as a power plant supplying load demands at Institut Teknologi Sepuluh Nopember (ITS) while serving as a laboratory to simulate hybrid electrical conditions in both on-grid and off-grid modes. For power generation function, REIDI produces 3,925.69 kWh per day with operational costs of Rp 1,220,109.61 and profit of Rp 4,334,738.58 without considering investment. When investment is considered, profit decreases to Rp 1,139,261.85. For laboratory utilization with a load profile of 4,786 kWh per day, optimization was performed on four scenarios: on-grid normal operation, on-grid with grid limitation, off-grid battery grid forming, and off-grid diesel grid forming. Research results show that on-grid normal operation scenario achieves the highest economic efficiency with operational costs of Rp 6,905,072.15. PV system demonstrates consistent 100% utilization across all scenarios, while biomass proves economical as baseload with costs of Rp 1,065.39 per kWh. Off-grid configurations experience significant cost increases of nearly one and a half times, confirming the fundamental trade-off between economic efficiency and energy independence.
