Can battery thermal runaway faults be detected early in energy-storage systems?

What are the simulated faults?

The simulated faults are three phase-to-ground in Figs. 7 a and 7 b and single-line-to-ground (SLG), as shown in Figs. 7 c and 7 (d). The voltage and current show abnormality

How does a fault current affect a dc grid?

The fault current then passes through the antiparallel diodes of the VSC, acting as an unstable rectifier (Joshua and Vittal, 2022), which may result in the complete failure of the DC grid (Augustine et al., 2021). Therefore, protection schemes must be robust and efficient to handle these issues promptly (Li et al., 2023a).
