　　With the transformation of the global energy structure and the rapid development of renewable energy, energy storage technology has gradually become a key link in regulating energy supply and demand, and improving energy utilization efficiency. Against this backdrop, distributed energy storage systems have emerged as an effective means of addressing energy instability and volatility. Distributed energy storage, with the help of miniaturized and modular energy storage devices, can store and release energy at the user end, thereby achieving flexible regulation of local power grids. This system can not only effectively balance the intermittency and instability of renewable energy sources (such as solar and wind energy) in the power generation process, but also provide reliable power support during peak demand periods, reducing the pressure on the power grid. This article introduces the application of the Acrel-1000DP distributed energy storage monitoring system by Ankerui in the 5MW distributed energy storage project of Jinyi Industrial in Jiaxing, Zhejiang. The system optimizes the energy management of the enterprise, effectively reduces power costs, and ensures the continuity and stability of production activities.

　　The safety automatic device 1) AM6-FE frequency and voltage emergency control device can monitor the frequency and voltage of the power grid in real time. Once an abnormal situation beyond the set range is detected, the control strategy is immediately activated. By adjusting the generator output, cutting off some loads, or using compensation equipment, the frequency and voltage of the power grid can be quickly restored to normal levels, ensuring the continuity and reliability of power supply. 2) The AM5SE-IS anti islanding device may form an islanding state when the distributed power source fails to disconnect from the power grid in a timely manner in the event of a power outage. This state may cause uncontrollable distributed power sources, voltage and frequency mismatch during power grid recovery, and may also lead to dangerous operations by power workers without their knowledge. The anti islanding device monitors the status of the power grid in real time. Once a power outage is detected, it can quickly cut off the connection between the distributed power source and the power grid within a specified time, thereby ensuring the safe operation of the power grid and the personal safety of maintenance personnel. 3) When the energy released by the energy storage power station exceeds the local load demand, the excess energy may flow into the grid, forming a reverse flow. The anti backflow protection device can monitor the direction and magnitude of the current in real time. Once the backflow phenomenon is detected, it will quickly act by cutting off relevant circuits or adjusting the output power of the energy storage system to prevent the backflow of electrical energy to the grid, ensuring the safety and stability of the system.
