It is a pioneering research for the fault characteristics analysis of transmission outgoing line. The results show that when a short circuit fault occurs in the outgoing line of the battery energy storage system, the fault current is limited by the inverter, and the zero sequence current has the greatest impact on the short circuit current.
In recent years, accidents such as spontaneous combustion and explosion have frequently occurred in the field of electrochemical energy storage, and thermal runaway caused by short-circuit faults in lithium-ion (Li-ion) batteries is one of the main reasons. This study investigated the internal short circuit (ISC) fault diagnosis method
The global grid energy storage market was estimated at 9.5‒11.4 GWh/year in 2020 (BloombergNEF (2020); IHS Markit (2021)7). By 2030, the market is expected to exceed 90 GWh, with some projections surpassing 120 GWh. Reaching 90 or 120 GWh represents compound annual growth rates (CAGRs) of 23% and 29%,
The purpose of Energy Storage Technologies (EST) is to manage energy by minimizing energy waste and improving energy efficiency in various processes [141]. During this process, secondary energy forms such as heat and electricity are stored, leading to a reduction in the consumption of primary energy forms like fossil fuels [ 142 ].

The current research of battery energy storage system (BESS) fault is fragmentary, which is one of the reasons for low accuracy of fault warning and diagnosis
2.1 Fault Analysis of Lithium-ion Battery. Knowledge of internal structure of lithium-ion battery helps us understand the internal mechanism of battery fault. In ideal case, only ion intercalation and deintercalation at both electrodes occur which do not result in irreversible capacity fade of battery.
The faults can be prevented from escalating to thermal runaway through early fault diagnosis and fault location of lithium-ion batteries and corresponding measures in time. To this end, based on the operational data of the lithium-ion battery energy storage system, the local outlier factor （LOF） algorithm is used for fault diagnosis and
ergy storage market will exceed 300 gigawatt-hours and 125 gigawatts of capacity by 2030. Those same forecas. s estimate that investments in energy storage will grow to $103 billion over that period. At the same time, the cost per kilowatt-hour of utility-scale battery systems is lik. ly to drop to less than half of today''s cost, making
The fault problems are classified into regular and sudden faults based on their durations. The regular fault reflects the inconsistency and degradation issues, while the sudden fault indicates the battery internal short circuit. The proposed method will be verified in the presence of such two types of faults in the following subsections.

Internal short circuit (ISC) is considered to be one of the main causes of battery thermal runaway, which is a critical obstacle to the application of lithium-ion batteries for energy storage. Aiming at inconspicuous characteristics and slow detection speed of early stage ISC faults, this paper proposes a fast diagnostic method for ISC based on
In Figure 10A, IGBT T 1 has an open-circuit fault at 0.1 s, whereas the fault diagnosis system locates the fault (label = 1) at 0.1201 s and issues protection instructions to the controller. The controller shuts down the system at 0.1204, so the current drops rapidly to avoid secondary failures.
