Batteries cannot provide peak power

Can a battery be used for peaking?

Unlike traditional thermal generation, batteries used for peaking could also be sited on the distribution network, potentially providing additional value [ 48 ]. While we focus on battery storage, these results are more generally applicable to storage with the same duration per unit of energy capacity.

Do lithium-ion batteries have a peak power?

Although there have been many studies on state estimation of lithium-ion batteries (LIBs), aging and temperature variation are seldom considered in peak power prediction during the whole life of the battery.

Does battery storage provide peaking capacity?

There is significant focus on the ability of battery storage to provide peaking capacity. Batteries (particularly lithium-ion based batteries) are increasingly cost-competitive compared to fossil-fueled peaking capacity, but their cost-competitiveness declines rapidly beyond about 4–8 h of duration [ 8 ].

What affects the peak power capacity of a lithium ion battery?

As mentioned above, the peak power capability of LIBs is affected by themaximum charge and discharge current, the maximum and minimum cut-off voltage, the remaining available capacity of the battery, etc.

What is the predicted peak current of a battery?

When the SOC of the battery is 70%, the predicted peak current is 117.4 A, with a relative error of 4.5%; When the SOC of the battery is 50%, the predicted peak current is 101.6 A, with a relative error of 8.1%; When the SOC of the battery is 20%, the predicted peak current is 40.34 A, with a relative error of 5.0%.

What are the problems in battery power prediction?

Based on existing research, the problems in battery power prediction are as follows: (1) It is necessary to obtain battery parameters under different aging and temperature states through a large number of experiments, which requires a large amount of preliminary work.
