Any grid connected storage system can be seen as a so-called black box with certain measures of performance (MoP). The definition of the MoP is the same for every kind of storage system regardless of what’s inside the black box, but the technology and design choices of a particular system determine their value.
The table below lists a minimal set of characteristics of a battery based storage system; it is a subset of the definitions in the GRIDSTOR RP document (1). The definitions from IEC 62933-1 CDV are used (9) for electrical energy storage systems.
