Abstract:

Energy storage has attracted considerable attention as a key technology enabling the development of smart grids and energy transformation, with battery energy storage represented by lithium-ion batteries becoming one of the preferred storage carriers for large-scale energy storage. However, with the gradual increase in the scale of battery energy storage applications, new challenges and risks in the quality and safety of energy storage systems have emerged. The battery energy storage system is not yet mature as a complete electrical equipment product, and there is uncertainty in the overall safety and quality status of energy storage power stations, resulting in low utilization rates of many existing energy storage power stations. Due to the immaturity and continuous iterative development process of the entire equipment product, it is particularly important to conduct a comprehensive performance evaluation around the core component of lithium-ion batteries for energy storage to improve the application level of lithium-ion battery energy storage power stations at the current stage, guided by safe and high-quality applications. This research reviews the latest progress of domestic standards related to energy storage of lithium-ion batteries. It provides a detailed analysis of the core standard for lithium-ion battery energy storage and its role in industry development. Based on the evaluation of battery energy storage characteristics and research accumulation of testing technology, a comprehensive solution has been proposed for the full process testing and evaluation of battery energy storage, including testing type, evaluation level, sampling arrival, testing grid connection, and operation assessment testing. It is demonstrated through detailed analysis of each link that the scheme can achieve closed-loop management of the entire chain of energy storage equipment on the grid side, power supply side, and user side involved in grid operation, which is of great significance for enhancing the standardization level of the battery energy storage equipment before the operation, improving the operation reliability of the energy storage power station, and reducing the safety risks of the energy storage power station.
