To harmonize the capability specification of battery energy storage systems with the requirements of electrical power systems the values ‘usable capacity regarding constant battery power’ and associated ‘minimum charge and discharge durations’ are used. In this regard, a sample battery rack is considered as a battery energy storage system. By introducing power based performance characteristics the capabilities of battery energy storage systems become more predictable. Additionally reliability of system design is improved.
