This work describes an improved risk assessment approach for analyzing safety designs in the battery energy storage system incorporated in large-scale solar to improve accident prevention and mitigation, via incorporating probabilistic event tree and systems theoretic analysis. The causal factors and mitigation measures are presented.
To reduce the safety risk associated with large battery systems, it is imperative to consider and test the safety at all levels, from the cell level through module and battery level and all the way to the system level, to ensure that all the safety controls of the system work as expected.
Risk management for BESS (Battery Energy Storage Systems) involves identifying potential hazards, assessing the likelihood and impact of these hazards, and implementing measures to mitigate them. This proactive approach can help prevent incidents and ensure the safe operation of energy storage systems.
