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.
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.
Efficiency of the storage plant is shown to have minimal impact in cases of small energy capacity but can have a supressing effect for larger-sized plants. This is because when charging efficiency is low, more energy is required to charge to the same level of energy.
The term capacity value refers to the dependable capacity a storage plant can provide upon which a network planner can rely so as to avoid network reinforcements triggered by an increase in demand. Until now, research has been primarily focused on distributed generation (DG) resources.
