Gradually build a new energy storage standard system that ADAPTS to the trend of technological innovation, meets the needs of industrial development, and benchmarks the international advanced level.

2. Standard system
(1) System framework.
According to the construction logic of the new energy storage power station, the framework of the new energy storage standard system is divided into eight aspects: basic general purpose, planning and design, equipment testing, construction acceptance, grid-connected operation, overhaul monitoring, operation and maintenance, and safety emergency, based on different functional requirements, product and technology types, and the correlation between subsystems.
