Abstract. Accurate estimation of state-of-charge (SOC) is critical for guaranteeing the safety and stability of lithium-ion battery energy storage system.
There are different energy storage solutions available today, but lithium-ion batteries are currently the technology of choice due to their cost-effectiveness and high efficiency. Battery Energy Storage Systems, or BESS, are rechargeable batteries that can store energy from different sources and discharge it when needed.
The energy storage battery undergoes repeated charge and discharge cycles from 5:00 to 10:00 and 15:00 to 18:00 to mitigate the fluctuations in photovoltaic (PV) power. The high power output from 10:00 to 15:00 requires a high voltage tolerance level of the transmission line, thereby increasing the construction cost of the regional grid.
