Scope

Scope: This standard specifies the principles and technical requirements that should be followed when prefabricated cabin-type lithium battery energy storage systems are connected to DC power grids, including power quality, power control, grid adaptability, protection and safety automatic devices, communication and automation, power metering, external interfaces, and grid connection testing. This standard applies to prefabricated cabin-type lithium battery energy storage systems with a rated power of 44MW or less that are connected to DC power grids with a nominal voltage of ±35kV or lower. Prefabricated cabin-type lithium battery energy storage systems of other power ratings and voltage levels may refer to this standard for implementation. Main technical content: This standard specifies the principles and technical requirements that should be followed when prefabricated cabin-type lithium battery energy storage systems are connected to DC power grids, including power quality, power control, grid adaptability, protection and safety automatic devices, communication and automation, power metering, external interfaces, and grid connection testing. (1) Terms and definitions include the definitions of prefabricated cabin-type lithium battery energy storage systems, DC power grids, DC voltage imbalance, DC voltage ripple factor, and DC voltage sags. (2) General principles specify the principles that should be followed when prefabricated cabin-type lithium battery energy storage systems are connected to DC power grids. (3) Connection conditions specify the technical requirements for voltage matching, power quality, power control, voltage regulation fault ride-through, protection and safety automatic devices, communication and automation, power metering, and external interfaces. (4) Connection tests specify the technical requirements for power quality tests, power control tests, grid adaptability tests, charge/discharge time tests, grid-interactive protection fu
