Despite widely known hazards and safety design of grid-scale battery energy storage systems, there is a lack of established risk management schemes and models as compared to the chemical, aviation, nuclear and the petroleum industry.
This can happen when a grid does not have adequate RES generation capacity and at the same time there is a lack of sufficient excess energy from wind and solar to be stored in batteries. Even though in some times of the day, there might be significant amount of excess energy and BESS alone might supply the peak demand.
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.
Traditional risk assessment methods such as Event Tree Analysis, Fault Tree Analysis, Failure Modes and Effects Analysis, Hazards and Operability, and Systems Theoretic Process Analysis are becoming inadequate for designing accident prevention and mitigation measures in complex power systems.
