Abstract

Sistem tenaga listrik di kepulauan dengan penetrasi fotovoltaik (PV) mengalami kendala operasional yang signifikan karena intermittency pasokan listrik, dan ketidakstabilan frekuensi. Battery Energy Storage System (BESS) biasanya digunakan untuk mengurangi masalah ini, namun siklus pengisian dan pengosongan yang intensif dalam durasi yang singkat mempercepat penuaan baterai dan meningkatkan biaya siklus hidup. Makalah ini mengkaji arsitektur hybrid energy storage system (HESS) yang menggabungkan BESS dengan flywheel energy storage system (FESS) untuk mengurangi flukttuasi tenaga yang tinggi pada baterai. Penilaian tekno-ekonomi dilakukan untuk sistem Nusa Penida di Indonesia menggunakan simulasi DIgSILENT PowerFactory. Model simulasi yang divalidasi terhadap data operasional aktual menunjukkan kemiripan lebih dari 95%. Hasil menunjukkan bahwa integrasi FESS secara efektif menyerap fluktuasi frekuensi tinggi, memperpanjang masa pakai baterai hingga 3,86 kali menurut pemodelan degradasi semi-empiris. Secara ekonomi, konfigurasi hybrid menurunkan levelized cost of electricity (LCOE) dari Rp 1.112/kWh menjadi Rp 1.069/kWh dan Net Present Value (NPV) sebesar Rp 12,58 miliar. Hasil penelitian menunjukkan bahwa integrasi FESS mendukung penerapan sistem hibrida PV–BESS–FESS untuk jaringan listrik kepulauan.

Electric power systems on islands with high photovoltaic (PV) penetration experience significant operational constraints due to power intermittency, and frequency instability. Battery Energy Storage Systems (BESS) are commonly used to mitigate this problem, however intensive charge and discharge cycles of short duration accelerate electrochemical battery aging and increase life cycle costs. This paper examines a hybrid energy storage system (HESS) architecture that combines a BESS with a Flywheel Energy Storage System (FESS) to eliminate high-frequency power from battery operation. A techno-economic assessment was carried out for the Nusa Penida network in Indonesia using dynamic simulation in DIgSILENT PowerFactory. The simulation model was validated against actual operational data, showing a similarity of more than 95%. Results show that FESS integration effectively absorbs high-frequency transients, extending battery life by 3.86 times according to semi-empirical degradation modeling. Economically, the hybrid configuration reduces the Average Cost of Electricity (LCOE) from IDR 1,112/kWh to IDR 1,069/kWh and the Net Present Value (NPV) of IDR 12.58 billion. The research results show that FESS integration supporting the application of PV–BESS–FESS hybrid systems for renewable energy-dominated island power grids.
