Introduction Energy storage technology is an indispensable support technology for the development of smart grids and renewable energy . The energy storage system plays an essential role in the context of energy-saving and gain from the demand side and provides benefits in terms of energy-saving and energy cost .
Furthermore, a wavelet-transform-based anti-misjudgment method that ensures the reliability of the fault warning and location is proposed. Thus, a nonintrusive, timely, and effective solution to ensure the safety of the battery energy storage system (BESS) is provided.
The range of abnormal voltage is from 0 to 3.39 V, and the temperature range is from 22 to 28 °C. The current jump is caused by the switching between charging and discharging of the energy storage power station. The SOC ranges from 17.5 to 86.6%.
Early and precise prediction of voltage anomalies during the operation of energy storage stations is crucial to prevent the occurrence of voltage-related faults, as these anomalies often indicate the possibility of more serious issues.
