Abstract

Vanadium Redox Flow Battery (VRFB) telah muncul sebagai solusi potensial untuk penyimpanan energi terbarukan karena skalabilitas dan masa pakainya yang lama. Namun, mengoptimalkan efisiensi operasional mereka dan mengatasi masalah akurasi parameter untuk beban yang tepat menimbulkan tantangan yang signifikan. Makalah ini bertujuan untuk mengukur parameter kritis VRFB dan menganalisis kinerjanya dalam memberi daya pada sistem dalam berbagai kondisi operasi laju aliran. Simulasi dilakukan menggunakan perangkat lunak MATLAB dan blok unit untuk mengevaluasi perilaku VRFB selama kondisi pengosongan dan pengisian pada tiga laju aliran elektrolit: 10, 5, dan 1 liter per menit (lpm). Analisis berfokus pada parameter utama, termasuk durasi pengoperasian, waktu pengisian/pengosongan, dan status pengisian. Hasil penelitian menunjukkan bahwa laju aliran yang lebih tinggi meningkatkan durasi pelepasan, sementara laju aliran yang lebih rendah menyebabkan waktu pengoperasian yang lebih pendek dan riak yang lebih menonjol yang disebabkan oleh ketidakstabilan kontrol pompa dan variasi kepadatan elektrolit. Oleh karena itu, merancang parameter yang sesuai dalam sistem VRFB sangat penting untuk mengembangkan solusi penyimpanan energi berkelanjutan dan mendukung penerapan teknologi energi bersih.

Vanadium Redox Flow Batteries (VRFB) have emerged as a potential solution for renewable energy storage due to their scalability and long lifetime. However, optimizing their operational efficiency and addressing the issue of parameter accuracy for the right load pose significant challenges. This paper aims to quantify the critical parameters of VRFBs and analyze their performance in powering the system under various flow rate operating conditions. Simulations are performed using MATLAB software and unit blocks to evaluate the behavior of VRFBs during discharge and charging conditions at three electrolyte flow rates: 10, 5, and 1 liter per minute (lpm). The analysis focuses on key parameters, including operating duration, charging/discharge time, and state of charge. The results show that higher flow rates increase the discharge duration, while lower flow rates lead to shorter operating times and more pronounced ripples caused by pump control instability and electrolyte density variations. Therefore, designing appropriate parameters in VRFB systems is critical to developing sustainable energy storage solutions and supporting the implementation of clean energy technologies.
