Case4: 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.
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.
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.
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.
An appropriately dimensioned and strategically located energy storage system has the potential to effectively address peak energy demand, optimize the addition of renewable and distributed energy sources, assist in managing the power quality and reduce the expenses associated with expanding distribution networks.
Through understanding ESS placement issues and possible impacts after placement, the deployment of ESSs in a distribution network and the associated development of smart grids will be greatly facilitated. Overall, ESSs can improve the performance of a distribution network.
