With the majority of renewable energy generation producing direct current (DC) output, the seamless integration of distributed power into DC distribution networks presents an opportunity to reduce commutation links, resulting in cost and loss reductions [3].
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 energy storage service is charged based on the power consumed. Following the use of the service, the distributed energy storage unit provides some of the power as stipulated in the contract, while the remaining power is procured from the DNO. (8) min C 2 = ∑ i ∈ N n β s a l e P E C, i (t) + c g r i d (P l o a d, i (t) − P E C, i (t)) 3.4.
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 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.
