Scope

Scope: This standard specifies the structure, basic requirements, performance requirements, and test methods of electrochemical energy storage backup power systems. This standard applies to electrochemical energy storage backup power systems with voltage levels ranging from 380V to 10kV, including generator black-start on the power supply side and temporary backup power on the load side. Main technical content: With the implementation of China's "Double Carbon" strategy and the widespread application of renewable energy, the power system faces the challenges of diversified power supply and multi-faceted electricity consumption. Therefore, to ensure reliable power supply and safe electricity use for users, the power system has very high standards for backup power. For the main power supply and standby power of the "source-grid-load" system in the power system, there are corresponding standards, but they all target additional backup power generators, gasoline and diesel generators, UPSs, etc. They do not involve interaction with other energy storage devices or aspects such as deployment and transportation. To ensure the safety, stability, and continuity of the power system and to give full play to the role of electrochemical energy storage systems in the power system backup power system, it is necessary to formulate corresponding technical specifications based on the actual situation of the power system, the technical characteristics of electrochemical energy storage backup power systems, and the specific needs of power users. Therefore, it is planned to develop the standard "Technical Specifications for Electrochemical Energy Storage Systems for Power Backup".
