Energy storage is critical in distributed energy systems to decouple the time of energy production from the time of power use. By using energy storage, consumers deploying DER systems like rooftop solar can, for example, generate power when it''s sunny out and deploy it later during the peak of energy demand in the evening.
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.
