As renewable energy, characterised by its intermittent nature, increasingly penetrates the conventional power grid, the role of energy storage systems (ESS) in maintaining energy balance becomes paramount. This dynamic necessitates a rigorous reliability assessment of ESS to ensure consistent energy availability and system stability.
Three-dimensional research directions in fault diagnosis of lithium-ion battery energy storage station. In summary, the aforementioned literature deeply investigates fault diagnosis methods, transmission systems, and multi-scenario-oriented public datasets for energy storage systems.
In battery system fault diagnosis, finding a suitable extraction method of fault feature parameters is the basis for battery system fault diagnosis in real-vehicle operation conditions. At present, model-based fault diagnosis methods are still the hot spot of research.
Yet the faults of batteries are coupled with each other, and the actual faults usually are the simultaneous occurrence of multiple faults, so the combination of information fusion technology and battery system fault diagnosis is the future tendency. The advantages and disadvantages of data-driven fault diagnosis methods are compared in Table 7.
These indicators are crafted to reflect critical aspects such as cyclic stress from charging and discharging, the impact of environmental conditions on material degradation, and responses to grid fluctuations, which are unique to the domain of energy storage.
Notably, since the voltage and capacity of a single battery cell cannot meet the requirements of power grid integration, LIB energy storage is composed of a huge number of cells connected in series and parallel, that is, battery energy storage station (BESS) .
