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.
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.
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.
In summary, configuring and sharing an energy storage device among multiple agents, in consideration of their respective interests, can lead to more efficient utilization of the device. Moreover, such a setup can determine the most suitable configuration and operation mode under the influence of various factors.
The model considers the concerns of stakeholders in shared energy storage, including investors, users, and power grid operators. Additionally, the impact of intricate factors, such as actual distribution network topology and power flow, is taken into consideration.
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.

At present, capillary hydrogen storage greatly exceeds DOE targets in many areas. However, capillary storage does not meet the DOE targets for volumetric capacity and a large amount of energy is needed to release hydrogen from the capillaries. The systems also have limited long-term durability. Therefore, they are not currently in use [30].
