Abstract

Indonesia, as the largest archipelagic country, faces significant challenges in providing consistent electricity to its numerous isolated microgrids, many of which rely on diesel generators. The limited operational hours of these systems hinder economic growth, especially in remote regions like Rhun Island. This research aimed to develop an optimized hybrid power system integrating photovoltaic (PV) panels and Battery Energy Storage Systems (BESS) to extend electricity availability and reduce reliance on fossil fuels. Using simulation tools such as PVsyst and HOMER Pro, the study evaluated various configurations to identify the most cost-efficient and sustainable solution. Additionally, Demand Side Management (DSM) strategies, including peak clipping and load shifting, were applied to further optimize the system's performance and reduce operational costs. The findings demonstrated that the hybrid system significantly decreased the Levelized Cost of Energy (LCOE) to $0.431/kWh compared to a diesel-only system. Furthermore, the renewable energy fraction increased to 81.7%, contributing to Indonesia's energy transition goals. This research offers a replicable model for other small islands, promoting sustainable energy solutions and supporting local economic development by ensuring a stable 24-hour power supply. The implications suggest that adopting hybrid systems with DSM can accelerate energy equity and environmental sustainability in remote areas.

Abstract

An efficient electrical system is essential to meet the energy needs of the community without incurring high operational costs. This study aims to compare the total operational costs of power plants during three extreme time periods: low load (00:00–05:00), medium load (06:00–18:00), and high load (19:00–23:00), and to determine the most efficient combination of power plants using the Unit Commitment (UC) method based on priority list techniques. The study was conducted on the Bengkulu regional power system with the assumption of zero startup costs due to data limitations. Simulation results show that coal-fired power plants (IPP), hydroelectric power plants, and micro-hydro power plants serve as the base load power plants that are always active due to their low operational costs, while diesel power plants are only used as supplements when load exceeds the capacity of the main power plants. The lowest total operational cost occurs during low-load periods at Rp 40,936,446/hour, while the highest cost occurs during peak-load periods at Rp 65,040,329/hour. This finding confirms that optimizing the combination of power plants based on cost efficiency can significantly reduce operational expenses. In the future, it is expected that the electricity system can adopt smart grid technology to reduce, even eliminate, the use of inefficient diesel power plants.

Abstract

Pulau Sebesi di Provinsi Lampung saat ini masih mengandalkan Pembangkit Listrik Tenaga Diesel (PLTD) untuk kebutuhan energinya, dengan beban rata-rata sebesar 100 kW dan biaya pokok produksi (BPP) listrik mencapai Rp 5.539/kWh. Tingginya BPP serta target pemerintah untuk mencapai Net Zero Emission pada tahun 2060 mendorong perlunya konversi ke sistem pembangkit energi terbarukan. Penelitian ini bertujuan untuk menganalisis keekonomian dan optimasi biaya dari sistem Hybrid Renewable Energy System (HRES) di Pulau Sebesi yang menggabungkan PLTD dengan Pembangkit Listrik Tenaga Surya (PLTS), Pembangkit Listrik Tenaga Hidrogen (PLTH2), serta Battery Energy Storage System (BESS).Tiga skema simulasi dilakukan: Skema 1 (Hybrid PLTD dan PLTS), Skema 2 (Hybrid PLTD dan PLTH2 150 kW), dan Skema 3 (Hybrid PLTD, PLTH2 150 kW, dan PLTS 300 kW). Simulasi dilakukan menggunakan aplikasi Homer untuk menghitung Levelized Cost of Energy (LCOE), biaya operasional, serta emisi Gas Rumah Kaca (GRK). Hasil penelitian menunjukkan bahwa semua skema layak diimplementasikan, namun Skema 3 paling optimal dengan LCOE terendah sebesar $0.247/kWh, pengurangan emisi CO hingga 99,1%, serta Return on Investment (ROI) tertinggi sebesar 101,4%. Skema ini terbukti paling efisien dan menguntungkan dari segi ekonomi dan lingkungan. Penelitian ini memberikan referensi penting bagi PT PLN (Persero) dalam pengembangan pembangkit energi baru terbarukan di wilayah Terdepan, Terluar, dan Tertinggal (3T) untuk mendukung program dedieselisasi serta pemerataan akses listrik di seluruh Indonesia. pemeliharaan PLTP maupun PLTU. Selain itu import daya dari Sumbagsel perlu dilakukan filter pemilihan renewable energi untuk mengurangi dampak emisi yang berlebih dalam menjaga keandalan sistem.
