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.
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.
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.
Energy storage devices are distributed across multiple nodes of the distribution network for joint use by EC and DNO. EC purchases energy storage resources based on electricity demand, but the purchase amount is limited to ensure convergence of the tidal current and DNO’s availability of energy storage resources.
The energy storage device can only obtain power from the DER and supply power to the distribution network but cannot purchase power from it. This example illustrates the difference between coupling and decoupling of DER and energy storage device locations.
Other energy storage technologies In addition to the above storage technologies, there are other energy storage technologies that have been employed in distribution networks, including compressed air energy storage, pumped hydro energy storage and hydrogen energy storage (fuel cell).
