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.
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 systems For distribution networks, an ESS converts electrical energy from a power network, via an external interface, into a form that can be stored and converted back to electrical energy when needed, , .
As mentioned above, distributed energy storage has its corresponding application scenarios in each part of a power system, including source, network and load. In different application scenarios, the capacity determination, location selection and coordinated operation of energy storage have different technical indicators or economic considerations.
Therefore, it is necessary to plan and study the energy storage and capacity of distribution network. method for distribution network based on cluster division. Firstly, the distribution network is divided network cluster node multi-level grid structure. Second, a two-level coordinated location and volume results of cluster division.
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.
Properly configuring energy storage devices in distribution systems is crucial to enhance the integration and absorption of renewable energy generation, while economic factors also need to be taken into
