Technical Conditions for Distributed Energy Storage System Access to Distribution Station Control Devices

This standard specifies technical conditions for distributed energy storage systems accessing distribution station control devices, focusing on voltage stability control at the low-voltage side of 10kV transformers. It leverages power IoT and edge computing in new distribution terminals to optimize source-grid-load interactions, promote local renewable energy accommodation, and reduce voltage fluctuations. The document covers general requirements, safety, functions like transient fluctuation detection and suppression, operation mode switching, accommodation control planning, and energy storage health evaluation. It details control and communication interfaces including power line carrier, wireless (4G/5G), Ethernet, 433MHz, Bluetooth, and serial communication. Hardware and software requirements for interface devices are defined, including measurement, communication ports, software architecture, data sharing, remote updates, and algorithm libraries. Applicable to remotely controlled distributed storage in distribution stations, it excludes large storage stations or those without control interfaces. The standard references multiple national and industry standards to ensure interoperability and reliability.
