In terms of $, that can be translated into $/kWh, the main data to compare Battery Energy Storage Systems. Sinovoltaics’ advice: after explaining the concept of usable capacity (see later), it’s always wise to ask for a target price for the whole project in terms of $/kWh and $.
Therefore, the energy storage units with high SOH should participate in power distribution preferentially. Under the premise of meeting the power requirements, the units with low SOH should be in idle states to minimize the battery life loss. The block diagram of consensus factor selection is shown in Fig. 2.
