Get a quoteBased on the table, nodes with DER have higher energy storage configuration, maximum charging and discharging power, and maximum energy storage capacity. This indicates a greater demand and potential for energy storage at these nodes. Table 11. The energy storage configuration results for Case 4.
Therefore, a comprehensive configuration strategy of the allo-cation of centralised energy storage in transformer stations, the allocation of decentralised energy storage on lines and the upgrading of distribution lines is under researched.
Currently, the mainstream energy storage configuration methods can be divided into the sequential operation simulation-based configuration method, certainty configuration method and uncertainty configuration method.
The key issues in the optimal configuration of distributed energy storage are the selection of location, capacity allocation and operation strategy.
However, studies on shared energy storage configurations have primarily focused on the peer-to-peer competitive game relation among agents, neglecting the impact of network topology, power loss, and other practical factors on energy storage configuration.
When a large capacity decentralised energy storage is installed on each line, a better control effect can be achieved. However, the economic cost is very high. In case 5, the optimal distribution network planning scheme is obtained using energy storage allocation and line upgrading.
