[0002] Early energy storage systems were mainly based on mechanical energy storage, such as water pump energy storage and flywheel energy storage. The control methods of these systems are relatively simple, and are mainly adjusted through mechanical devices, such as adjusting the flow of water pumps or the speed of flywheels. However, these systems have certain limitations in energy density and efficiency. With the popularization of smart grids and renewable energy, the control methods of energy storage systems have further developed. The emergence of intelligent control systems enables energy storage systems to be better integrated with the power grid and achieve precise control of energy flow. Control methods have gradually evolved towards technical directions such as model prediction, optimization algorithms and artificial intelligence to achieve optimal operation of energy storage systems. In addition, targeted control methods have also emerged for different types of energy storage technologies, such as compressed air energy storage and supercapacitors. However, the current energy storage system control methods lack multi-scale coupling, making it difficult to accurately describe the complex dynamic characteristics of the system. At the same time, there is a lack of effective control models and optimized control strategies for battery status, resulting in low system operation efficiency or battery damage, which in turn leads to low efficiency and reliability of energy storage system control.

Analysis of characteristic data such as temperature and humidity can reveal the changing trend and correlation between sensors. Based on features such as humidity change rate and temperature change rate, similarity data between sensors are calculated, which helps to discover the correlation and pattern between sensors. Cluster analysis is performed based on the similarity data of the sensors, and sensors with similar characteristics and behavior patterns are classified into one category, thereby constructing the sensor perception network topology.
