Abstract

The use of renewable energy to replace fossil fuels in electricity generation systems has been increasing every year. Unlike fossil fuels, which can generate energy according to load demand, renewable energy sources produce power unpredictably. Therefore, batteries are needed for power shifting. Li-ion is the most commonly used battery, although it only has a life cycle of about 1500 - 4500 cycles. We need another type of battery as an alternative because if we only rely on Li-ion, it will cause battery waste, which is a problem for the environment. Liquid Metal Battery (LMB), according to the latest research, have a life cycle of up to 10,000 times, so they could eventually become a promising alternative. LMB is composed of modules with a combined configuration of parallel and series circuits and requires a management system, especially for the balancing process. Due to the large capacity of this battery type, bidirectional active balancing using a bidirectional flyback converter is an ideal alternative, as the process is fast and highly efficient. Fuzzy logic control can be used in this system because it does not require mathematical equations and is suitable for systems with multiple inputs and outputs.
