Also, the work aimed to collect numeric values of a number of common parameters used to analyze energy storage. These numeric values could then be used as basis for a first evaluation of the energy storage technology that is best suited to a given situation. The method was divided into three main phases.
This report describes development of an effort to assess Battery Energy Storage System (BESS) performance that the U.S. Department of Energy (DOE) Federal Energy Management Program (FEMP) and others can employ to evaluate performance of deployed BESS or solar photovoltaic (PV) +BESS systems.
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.
Efficiency is the sum of energy discharged from the battery divided by sum of energy charged into the battery (i.e., kWh in/kWh out). This must be summed over a time duration of many cycles so that initial and final states of charge become less important in the calculation of the value.
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 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.
