Application of digitalization in energy storage security

Judging from the environment in which energy storage power stations are put into operation, most of them are located in the Gobi Desert and have been in operation for more than 10 years. The effect of monitoring, maintaining, and tracking power stations solely through human labor is very limited, and most of the time they are unattended. .

Therefore, the investment of energy storage power stations in digital technologies such as remote control, BMS, EMS, and AI can effectively provide early warning of energy storage power station accidents and stop losses in a timely manner. Not only that, the digitalization of energy storage systems can further meet the needs of new power systems for safety, efficiency, flexibility, flexibility, and intelligence, and unleash the true value of energy storage.

Li Feng, chairman of Cairi Energy, also told Gaogong Energy Storage that experience, data, and algorithms are the core of the future of the energy storage market. "Through in-depth continuous verification and continuous repair of algorithms, energy storage security can be ensured with maximum efficiency.

Specifically, the BMS is mainly responsible for monitoring the charging status of the battery and the temperature during the charging and discharging stages. When it is detected that the temperature exceeds the safe range, the BMS will form relevant data and report it to the upper management system, and turn off the power in a timely manner to prevent the internal battery temperature from continuing to rise. rise.

Taking into account factors such as energy storage power stations moving towards GWh and the operation time of power stations for more than 10 years, higher requirements have been put forward for the reliability, accuracy, response speed and storage time of data processed by BMS.

EMS is responsible for monitoring fault anomalies during system operation, and performs visual fault prediction based on big data. It uses a variety of artificial intelligence algorithm models to conduct visual analysis of the battery life cycle, identify early signs of faults, and make safety warning designs to improve Energy storage security.

In CATL's zero-auxiliary source optical storage integration system, each string optical storage converter is equipped with an independent local energy management system (Local EMS), which can not only achieve millisecond-level response and achieve "zero" deviation in output power, When applied to safety aspects, timely accident warnings can be provided.

Huawei's digital energy FusionSolar intelligent optical storage solution realizes refined monitoring and charge and discharge management through the integration of digital technology and power electronics technology, and uses digital twin technology to sense every component of the power station to ensure more detailed safety.

Overseas, Fluence's latest product, the Gridstack Pro battery energy storage system, can handle more advanced data collection and thermal management, and provide comprehensive software control of all layers of the system architecture; Tesla has developed the Powerhub real-time monitoring platform, all Megapack All can be connected to the platform for managing energy storage power generation and microgrids.
