This can lead to significant line over-voltage and power flow reversal issues when numerous distributed energy resources (DERs) are connected to the distribution network , . Incorporation of distributed energy storage can mitigate the instability and economic uncertainty caused by DERs in the distribution network.
In this situation, the energy storage device is installed by the DNO at the DER node, which is physically linked to the distributed energy resource. The energy storage device can only receive power from DER and subsequently provide it to DNO for their use.
Furthermore, the power capacity of distributed energy storage must meet the constraint of battery charging rate (C-rate). This means that the ratio of battery power to capacity must be subject to the C-rate constraint.
Centralized energy storage is utilized, and the storage device is configured by the distribution network investment, with careful selection of location, capacity, and power to minimize the operational cost of the distribution network.
