Abstract

Sistem Timor menghadapi tantangan keandalan akibat pertumbuhan beban, keterbatasan pasokan, berakhirnya kontrak pembangkit berkapasitas besar 40 MW, serta ketidakseimbangan antara lokasi pembangkit dan pusat beban. Di sisi lain, wilayah Nusa Tenggara Timur memiliki potensi energi surya yang tinggi sehingga pemanfaatan Pembangkit Listrik Tenaga Surya (PLTS) yang dikombinasikan dengan Battery Energy Storage System (BESS) menjadi salah satu opsi untuk meningkatkan kecukupan daya sistem. Penelitian ini bertujuan menentukan kapasitas optimal PLTS dan BESS pada Sistem Timor dengan mempertimbangkan aspek keandalan dan keekonomian. Metode yang digunakan adalah simulasi HOMER dan optimasi Particle Swarm Optimization (PSO) berbasis data per jam selama satu tahun atau 8760 jam. Pada model PSO, optimasi kapasitas PLTS-BESS dilakukan berdasarkan residual defisit, yaitu sisa kebutuhan daya sistem per jam setelah memperhitungkan output dispatch pembangkit eksisting melalui simulasi HOMER. Hasil pengecekan data menunjukkan daya yang belum terpenuhi sebelum penambahan PLTS-BESS sebesar 3,483 GWh/tahun dengan kebutuhan daya maksimum yang belum terpenuhi sebesar 45,650 MW. Hasil PSO menghasilkan tambahan PLTS sebesar 23,329 MW dan BESS sebesar 45,650 MW/182,600 MWh, dengan unmet load 0 kWh/tahun dan Levelized Cost of Energy (LCOE) Rp2.239,87/kWh. Sementara itu, HOMER menghasilkan konfigurasi PLTS 24 MW dan BESS 60 MW/253 MWh dengan LCOE Rp1.985/kWh. Hasil HOMER digunakan sebagai acuan utama karena mampu melakukan dispatch sistem secara lebih lengkap, sedangkan PSO berperan sebagai metode pembanding sizing yang feasible secara teknis.

The Timor power system faces reliability challenges due to load growth, supply limitations, the expiration of a 40 MW large-scale power plant contract, and the imbalance between generation locations and load centers. On the other hand, East Nusa Tenggara has high solar energy potential, making the utilization of Solar Photovoltaic (PV) power plants combined with a Battery Energy Storage System (BESS) one of the potential options to improve system adequacy. This study aims to determine the optimal capacity of PV and BESS in the Timor power system by considering reliability and economic aspects. The methods used in this study are HOMER simulation and Particle Swarm Optimization (PSO) based on hourly data for one year, or 8760 hours. In the PSO model, the PV-BESS capacity optimization is performed based on residual deficit, defined as the hourly remaining power demand of the system after considering the existing generation dispatch output obtained through HOMER simulation. The data evaluation results show that the unmet power demand before the addition of PV-BESS is 3.483 GWh/year, with a maximum unmet power requirement of 45.650 MW. The PSO results provide an additional PV capacity of 23.329 MW and a BESS capacity of 45.650 MW/182.600 MWh, with an unmet load of 0 kWh/year and an Levelized Cost of Energy (LCOE) of IDR 2,239.87/kWh. Meanwhile, HOMER produces a configuration of 24 MW PV and 60 MW/253 MWh BESS with an LCOE of IDR 1,985/kWh. The HOMER result is used as the main reference because it is capable of performing a more comprehensive system dispatch, while PSO serves as a technically feasible sizing comparison method.
