The maximum amount of energy accumulated in the battery within the analysis period is the Demonstrated Capacity (kWh or MWh of storage exercised). In order to normalize and interpret results, Efficiency can be compared to rated efficiency and Demonstrated Capacity can be divided by rated capacity for a normalized Capacity Ratio.
That method compared actual metered PV system energy delivery with that of a computer model. The computer model used was the National Renewable Energy Laboratory's (NREL's) System Advisor Model (SAM). The KPIs reported are Availability (% up-time) and Performance Ratio (PR).
The energy storage capacity, E, is calculated using the efficiency calculated above to represent energy losses in the BESS itself. This is an approximation since actual battery efficiency will depend on operating parameters such as charge/discharge rate (Amps) and temperature.
Energy storage systems can help address intermittency challenges by storing excess energy for use when the supply of green power is less, ensuring a more reliable and stable grid.
