Customer ServiceCase4: The distribution network invests in the energy storage device, which is configured in the DER node to assist in improving the level of renewable energy consumption. The energy storage device can only obtain power from the DER and supply power to the distribution network but cannot purchase power from it.
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.
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.
The deployment of energy storage systems (ESSs) is a significant avenue for maximising the energy efficiency of a distribution network, and overall network performance can be enhanced by their optimal placement, sizing, and operation.
Typically, the distribution network operator (DNO) alone configures and manages the energy storage and distribution network, leading to a simpler benefit structure. , . Conversely, In the shared energy storage model, the energy storage operator and distribution network operator operate independently.
