【 摘 要 】

When distributed energy storage on user side is connected to the distribution network, it will have a significant impact on the distribution network. So the reasonable access for energy storage system has become a key problem. Therefore, this paper analyzes the impact on power distribution network loss and voltage stability by accessing distributed energy storage on user side. Firstly, the relationship between voltage stability of distribution network and distributed energy storage access is studied. It is concluded that the distributed energy storage is beneficial to the voltage stability of distribution network. Then the calculation method of distribution network loss before and after distributed energy storage access is analyzed. Finally, the access location of distributed energy storage is simulated and analyzed. Considering the network loss and voltage stability, it is concluded that small capacity distributed energy storage should be connected at the end of the line, and a certain large capacity distributed energy storage should be connected at the beginning of the line.
