Description

Technical Field

[0001] The present invention relates to the technical field of power grid operation assessment, and in particular to an online operation and maintenance supervision method and control method of energy storage device status based on AI supervision, an online operation and maintenance supervision system of energy storage device status based on AI supervision, electronic equipment and computer-readable storage medium. Background Art

[0002] The core purpose of energy storage system status monitoring is to ensure the health and safe operation of the energy storage system through regular inspections and assessments, including comprehensive monitoring of key components such as battery systems, power storage converters (PCS), and energy storage monitoring systems. Through status monitoring, the energy storage system can be ensured to operate safely and efficiently, and each component of the energy storage system can be monitored, evaluated, and maintained in real time.

[0003] The main contents of daily status supervision of energy storage systems are as follows: ‌1. Supervision of battery system‌: Batteries and battery management systems (BMS) are the core of energy storage systems. It is necessary to regularly check the clarity of equipment operation number identification and phase sequence identification, as well as the reliability of each connection point of the main circuit and secondary circuit of the battery system.

[0004] At the same time, it is necessary to monitor the health status of the battery system, including key parameters such as battery capacity, internal resistance, voltage, and environmental factors such as temperature and humidity in the battery room, to ensure that the battery operates in the best condition.

[0005] 2. Supervision of the PCS: The energy storage inverter is a key device that connects the battery system to the power grid. It is necessary to regularly check the appearance of the cabinet, the integrity of the door lock, and the working status of the temperature control device.

[0006] At the same time, it is necessary to monitor the operating parameters of the PCS, such as input / output voltage, current, power factor, etc., to ensure that it meets the design requirements and operates stably.

[0007] ‌3. Supervision of energy storage monitoring system‌: The energy storage monitoring system is responsible for data collection, processing and monitoring of the entire energy storage system. It is necessary to regularly check the operating status of the server, the switching of the functional interface, and the communication status between the monitoring system and the BMS, PCS and other systems.

[0008] Through the monitoring system, the operating status of the energy storage system can be monitored in real time, abnormal situations can be discovered and handled in a timely manner, and the safe and stable operation of the system can be ensured.

[0009] ‌4. Regular inspections and special inspections‌: In addition to daily inspections, special inspections are also required in special seasons, abnormal weather, and after abnormal equipment alarms or fault handling to ensure the safe and stable operation of the energy storage system. The inspection content should include a comprehensive inspection of key components such as the battery system, PCS, and energy storage monitoring system, as well as an inspection of the environmental conditions of the battery room or battery compartment. However, in the daily operation and maintenance of energy storage systems, system reactive power compensation is also required. The main reason for reactive power compensation in energy storage systems is to improve the stability and reliability of the power grid and to improve the power factor of the power system. This is because in the power system, reactive power is the phenomenon that the current lags or leads the voltage due to the presence of inductance and capacitance elements in the circuit. This phase difference between the lagging or leading current and voltage will cause the power factor of the power grid to decrease, which in turn affects the operating efficiency and stability of the power grid.

[0010] Therefore, through the reactive power compensation of the energy storage system, the reactive power in the power system can be effectively adjusted, the impact of reactive power on the power grid can be reduced, the overall operating efficiency of the power system can be improved, and line losses can be reduced. In addition, compared with traditional reactive power compensation equipment (such as static reactive power compensators, reactive power generators, etc.), the energy storage system is more flexible, efficient, and reliable, and can reduce dependence on traditional equipment. At the same time, reactive power is not useless power in the AC power supply system, and it has great significance for the transmission and exchange of energy. For example, the motor needs to establish and maintain a rotating magnetic field to make the rotor rotate, thereby driving mechanical movement, and reactive power is required in this process. Therefore, reactive power compensation of the energy storage system is also an important part of ensuring the normal operation of these devices.

[0011] However, during the charging and discharging process of the energy storage system, the current lags behind or leads the voltage due to the presence of inductance and capacitance elements in the circuit, so there is reactive power. This phase difference between the lagging or leading current and voltage will cause the power factor of the power grid to decrease, which in turn affects the operating efficiency and stability of the power grid. The energy storage system also needs to dynamically output or absorb reactive power, so the reactive compensation of the system energy storage equipment also needs to be considered in actual operation and maintenance. The main reason for reactive compensation of the energy storage system is to improve the stability and reliability of the power grid and improve the power factor of the power system. Through the reactive compensation of the energy storage system, the reactive power in the power system can be effectively adjusted, the impact of reactive power on the power grid can be reduced, the overall operating efficiency of the power system can be improved, and the line loss can be reduced. In addition, compared with traditional reactive compensation equipment (such as static reactive compensators, reactive generators, etc.), the energy storage system is more flexible, efficient, and reliable, and can reduce dependence on traditional equipment. At the same time, reactive power is not useless power in the AC power supply system, and it has great significance for the transmission and exchange of energy. For example, the motor needs to establish and maintain a rotating magnetic field to rotate the rotor, thereby driving mechanical movement. This process requires reactive power. Therefore, reactive power compensation of the energy storage system is also an important part of ensuring the normal operation of these devices.

[0012] The operation and maintenance supervision of existing energy storage equipment mainly focuses on routine supervision such as traditional batteries, PCS, and data collection, and lacks intelligent supervision methods for reactive power compensation. Even if reactive power compensation is actually needed, administrators usually conduct temporary offline operation and maintenance to adjust the parameters of the energy storage equipment to adjust the operating status of the energy storage equipment to achieve a charging and discharging effect that tends to the actual output. This method is only effective for individual or a small number of energy storage devices. Faced with a large number (more than dozens of) energy storage devices, the manual adjustment method is inefficient and not intelligent enough, and cannot meet the development needs of intelligent manufacturing equipment.

[0030] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0031] The embodiment of the present invention provides an online operation and maintenance supervision method for energy storage device status based on AI supervision, which can be implemented by an electronic device, which can be a terminal or a server. Figure 1 The flowchart of the online operation and maintenance supervision method of energy storage device status based on AI supervision is shown. The method is implemented based on the cooperation of the energy storage system coordination controller and the host computer. The energy storage system coordination controller is used to monitor the status data of the energy storage device and upload it to the host computer. The host computer analyzes the status data of the energy storage device and performs intelligent operation and maintenance supervision and management on the energy storage device. The method includes the following steps: S1, monitoring and uploading the status data of the energy storage device to the host computer through the energy storage system coordination controller; S2, the host computer inputs the state data into a preset state AI supervision model, identifies the state characteristic value in the state data through the state AI supervision model, and outputs a reactive power compensation operation and maintenance strategy matching the state characteristic value; S3, binding the reactive power compensation operation and maintenance strategy with the corresponding energy storage device, and sending it to the energy storage system coordination controller; S4. The energy storage system coordination controller executes the reactive power compensation operation and maintenance strategy on the energy storage device.

[0032] In this embodiment, the energy storage system coordination controller can be referred to as the controller; the host computer can be referred to as the background; the state AI supervision model can be referred to as the supervision model or AI model or model.

[0033] like Figure 2 As shown, compared with the traditional solution of manual reactive power compensation operation and maintenance by the administrator, the present invention adopts AI technology, monitors the status data of each energy storage device through the controller and reports it to the host computer, and the status AI supervision model of the host computer performs feature recognition on the status data of the corresponding intelligent device and determines whether there is corresponding reactive power compensation feature data (identifies and matches the status feature value): if there is corresponding feature data, the AI ​​model recognizes and outputs the reactive power compensation operation and maintenance strategy that matches the current status feature value and sends it to the controller, and the controller performs reactive power compensation on the corresponding energy storage device.

[0034] In the process of historical operation and maintenance management, the reactive power compensation records implemented by the administrator can be recorded and saved several times in the background (background database deployed on the host computer). The supervision model training and application can be carried out based on historical big data. The model supervision training can be carried out on the historical reactive power compensation operation and maintenance big data to build a state AI supervision model and deploy it on the host computer for subsequent intelligent supervision of the state of each energy storage device to determine whether to perform reactive power compensation. On the host computer, the historical big data can be stored in the corresponding background database. The corresponding model training can be completed on the background.

[0035] In the present invention, a controller is used to coordinate and control the energy storage devices in each energy storage system. The controller controls the state management of each energy storage device and the reactive compensation operation and maintenance supervision. The controller communicates with the host computer, and can collect the state data of the corresponding energy storage device and upload it to the host computer. The host computer then performs AI supervision and issues corresponding reactive compensation operation and maintenance strategies. The reactive compensation operation and maintenance strategy includes reactive compensation operation and maintenance instructions for the corresponding energy storage device (including control parameters of the corresponding state characteristic values), which can be handed over to the controller to perform corresponding reactive compensation operation and maintenance control on the corresponding device. Specifically, the reactive compensation control parameters issued for the state data of the corresponding device, etc., can be combined with historical big data for corresponding recommendation and output. Therefore, by adopting the present invention, the reactive compensation of each energy storage device in the energy storage system can be realized through the energy storage system coordination controller and the host computer, and intelligent operation and maintenance supervision and management can be realized, greatly improving the operation and maintenance efficiency.

[0036] like Figure 3 As shown, preferably, the energy storage system coordination controller includes a communication interface, a USB interface, a plurality of sensor interfaces and a mainboard, and the mainboard is configured with a task management CPU, a coordination control CPU and a safety communication CPU, wherein: The task management CPU is used to control the sampling of the sensor interface according to the preset sampling task and send the collected charging and discharging status data of the energy storage device to the coordination control CPU, wherein the charging and discharging status data includes the charging and discharging current, voltage, power, grid frequency and temperature value of the energy storage device; The coordination control CPU is used to forward the charging and discharging status data of the energy storage device to the safety communication CPU; The secure communication CPU is used to report the charge and discharge status data of the energy storage device to the host computer through the communication interface after secure encryption processing; The task management CPU is communicatively connected with the energy storage device via the sensor interface; The safety communication CPU is connected to the host computer through the communication interface; The coordination control CPU is connected to the energy storage device through the USB interface; The task management CPU, the coordination control CPU and the safety communication CPU are communicatively connected in sequence.

[0037] Preferably, the safety communication CPU is further used to: receive and decrypt the reactive power compensation operation and maintenance strategy issued by the host computer to the corresponding energy storage device, and forward the decrypted reactive power compensation operation and maintenance strategy to the coordination control CPU; The coordination control CPU is further used to: receive and analyze the reactive compensation operation and maintenance strategy, obtain the reactive compensation control instruction therein, and issue the reactive compensation control instruction to the energy storage device through the USB interface.

[0038] The standby machine is equipped with corresponding data interaction interfaces, including a communication interface for communicating with the host computer, a USB interface for interactive control with the energy storage device, and several sensor interfaces for status data sensing and monitoring. These interfaces are all arranged on the main board. The main board is also equipped with a corresponding multi-CPU working system, mainly including a task management CPU, a coordination control CPU, and a safety communication CPU. Each energy storage device is pre-configured with corresponding sensors, such as temperature sensors, current / voltage sensors, etc., which can communicate with the main board through the corresponding sensor interface and perform sensor collection of corresponding types of status data under the control of the main board. The main board, that is, the PCB board, has three integrated CPUs that can respectively realize corresponding status data collection, processing, and execution of corresponding calculation control. The CPU model on the controller can be configured according to user needs.

[0039] When sampling is required, the host computer can send the corresponding sampling instructions to the controller according to the sampling frequency (task) of the corresponding energy storage device. After the security communication CPU performs security processing (generally synchronized with the encryption algorithm adopted by the host computer, such as the host computer encrypts the instruction and sends it to the controller, which is decrypted by the controller's security communication CPU and then checked for security), the instruction is forwarded, and finally the task management CPU executes the corresponding sampling task. The sampling task includes the host computer's requirements for the sampling frequency, data format, and type of status data of the corresponding energy storage device. It can be executed according to the preset sampling task.

[0040] Therefore, the task management CPU can control the corresponding sensor interface, collect the charging and discharging status data of the corresponding energy storage device, and transmit it to the coordination control CPU. After coordination by the coordination control CPU, the charging status data of the corresponding energy storage device is transmitted to the security communication CPU, which encrypts it and reports it to the host computer.

[0041] The encryption and decryption algorithms used in the secure communication CPU, such as symmetric encryption or asymmetric encryption, or hash-based encryption and decryption algorithms, can be understood by referring to the security encryption and decryption algorithms used.

[0042] The encryption and decryption processing of data signals, task instructions, etc. on the host computer and controller can be specifically referred to the selected encryption and decryption algorithm, which will not be elaborated here.

[0043] After the upper computer receives the charge and discharge status data of the corresponding energy storage device, it will decrypt and identify the signal source in the data to determine the energy storage device to which the current status data belongs. The background will generate a sampling file for the corresponding energy storage device and record and bind the charge and discharge status data sampled this time, and then perform subsequent AI supervision. The management of the corresponding energy storage device in the background and the identification of the device identity of the corresponding energy storage device based on the status data can also refer to the existing background equipment management solutions. For example, when sampling, the device code of the current energy storage device can be written into its charge and discharge status data, etc., so as to identify the identity and perform identity verification in the background.

[0044] In the coordinated control CPU, because the controller needs to collect the status of several energy storage devices and supervise the reactive compensation operation and maintenance, the coordinated control CPU can use a preset coordination management mechanism, such as a message queue, to orderly report the data of each energy storage device to the safety communication CPU. At the same time, it can also process some priority devices. For example, when the coordinated control CPU receives the charging and discharging status data of the corresponding energy storage device uploaded by the task management CPU, it can identify whether there is a corresponding priority mark in its status data. If there is a corresponding priority mark, the coordinated control CPU can perform coordinated control and report the status data with a priority mark to the host computer through the safety communication CPU first, so as to realize coordinated data reporting, prioritize uploading of important parameters, and orderly coordinate system equipment message transmission and routing.

[0045] Preferably, the energy storage system coordination controller further includes: Memory A, used to provide storage services for the safety communication CPU, including: storing the charging and discharging state data of the energy storage device sampled and reported each time, and the reactive compensation operation and maintenance strategy received accordingly; The memory A is communicatively connected to the safety communication CPU.

[0046] Preferably, the energy storage system coordination controller further includes: Memory B, used to provide storage services for the task management CPU, including: storing the charge and discharge state data of the energy storage device collected by each sampling; The memory B is communicatively connected to the task management CPU.

[0047] The memory may be, for example, a CMOS memory or a Flash memory, etc., which can store the data generated by the corresponding CPU, so as to facilitate the controller to record and back up.

[0048] like Figure 4 As shown, preferably, the method for generating the state AI supervision model includes: Collecting historical operation and maintenance supervision big data of some of the energy storage devices from the background database of the host computer, including historical status data of the energy storage devices and reactive power compensation operation and maintenance strategies issued by system operation and maintenance supervision, wherein the reactive power compensation operation and maintenance strategies include corresponding reactive power compensation control instructions; Feature engineering is performed on the historical operation and maintenance supervision big data, and a supervised learning algorithm is used to extract feature data from the historical operation and maintenance supervision big data, including the state feature values ​​in each group of the historical state data and the reactive compensation control instructions and strategy keywords corresponding to the state feature values ​​in the reactive compensation operation and maintenance strategy, and the state feature values ​​are bound to the strategy keywords to obtain the extracted features of each group: {state characteristic value, strategy keyword}; Collecting feature extraction results of each of the energy storage devices to obtain a feature set consisting of several groups of {state feature values, strategy keywords}; Dividing the feature set into a training set and a validation set according to a preset ratio; Input the training set into the default machine learning model, and train it according to the preset optimized iterative training conditions to construct the state AI supervision model; The performance of the state AI supervision model is verified using the validation set: If the verification is successful, the state AI supervision model is deployed and applied to the host computer; If the verification fails, repeat the above steps and retrain the model.

[0049] The data of reactive compensation operation and maintenance supervision conducted by the administrator in the past can be recorded in the system database. When training the model, the big data of historical operation and maintenance supervision can be retrieved and collected from the background database, including the analysis of the historical status data of the corresponding storage equipment and the corresponding reactive compensation operation and maintenance instructions issued. Each historical status data and the corresponding reactive compensation operation and maintenance strategy constitute a set of historical operation and maintenance supervision data; several sets of data constitute big data.

[0050] The reactive compensation operation and maintenance strategy that the administrator controls and generates based on the historical status data of the corresponding energy storage device includes the corresponding reactive compensation control instructions, which can be current compensation, voltage compensation, or compensation of the corresponding power factor. The corresponding reactive compensation control instructions are determined based on the operating parameters in the corresponding historical status data. For example, if it is found through analysis that the current is lagging or the voltage is leading, the corresponding type of reactive compensation current or reactive compensation voltage can be generated to balance the power factor, so that the charging and discharging power of the energy storage device reaches a balanced state, so that the charging and discharging is stable, the charging and discharging power grid composed of the energy storage device has the best operating efficiency, and maintains better stability.

[0051] Therefore, the reactive power compensation operation and maintenance strategy that has been set for the corresponding state in the past can be determined by the administrator according to the reactive power compensation analysis results generated by the specific analysis to determine the corresponding reactive power compensation operation and maintenance strategy.

[0052] After collecting the historical operation and maintenance supervision big data, feature engineering is required to extract the data features under each set of data. Using the supervised learning algorithm, the state feature values ​​in the historical state data in each set of data are extracted, such as the current value or voltage value with operation differences, or the power value, temperature value, etc., which may affect the operation of the system and require corresponding reactive power compensation. Therefore, the supervised learning algorithm can be used to extract the state feature values ​​in the state data of each set of data, and the reactive power compensation operation and maintenance strategy in the set of data can be analyzed to extract the corresponding strategy keywords, such as "current compensation" or "voltage compensation", etc.; at the same time, the corresponding instructions in the operation and maintenance strategy can be extracted, so as to bind the extracted strategy keywords and instructions with the corresponding state feature values, so that the subsequent model can match and output the corresponding strategy keywords and instructions according to the identified features.

[0053] The steps of using supervised learning algorithms to extract data features and their correlations in each set of data can be referred to as follows: 1. Data Collection and Preprocessing ‌Data Collection‌: Collect relevant data from various sensors, monitoring systems and other channels of the energy storage system, including the following status data: battery status, temperature, voltage, current, power factor and other parameters, as well as system operating status, alarm information (system reactive power compensation strategy or alarm instructions / information related to reactive power compensation, etc., which contain corresponding reactive power compensation control parameters), etc.

[0054] ‌Data Cleansing‌: Clean the collected data to remove duplicate, missing or abnormal data records to ensure the accuracy and completeness of the data.

[0055] ‌Data Standardization‌: Standardize data from different sources and in different formats, unify data formats and units, and facilitate subsequent data analysis and processing.

[0056] 2. Feature Selection and Extraction ‌Feature Selection‌: According to the requirements of energy storage system status monitoring, features related to the energy storage system status are selected from the preprocessed data. These features may include physical quantities such as battery temperature, voltage, current, power factor, as well as system operation time, load conditions, alarm information, etc.

[0057] ‌Feature Extraction‌: Features that are more directly related to the state of the energy storage system can be extracted from the raw data using statistical methods, mathematical transformations, or domain knowledge. For example, statistical features such as the average temperature, maximum temperature difference, and voltage fluctuation range of the battery can be calculated, or frequency domain features of the signal can be extracted using methods such as Fourier transform.

[0058] 3. Data Annotation and Training Set Construction ‌Data Annotation‌: The extracted feature data is labeled (in this embodiment, the extracted features of the group are: {state feature value, strategy keyword}, ​​and the label is on the state feature value), that is, each group of data is labeled accordingly according to the actual state of the energy storage system or expert knowledge. For example, the data can be divided into categories such as "normal", "warning", and "fault" according to the health status of the battery.

[0059] ‌Training set construction‌: The labeled data is divided into a training set and a validation set (for example, in a ratio of 8:2) for subsequent training and evaluation of the supervised learning model.

[0060] IV. Supervised Learning Model Training and Optimization ‌Model Selection‌: According to the specific needs and data characteristics of the energy storage system state supervision, select the appropriate supervised learning algorithm. For example, for classification problems, you can choose algorithms such as logistic regression, support vector machine, decision tree, random forest, etc.; for regression problems, you can choose algorithms such as linear regression and polynomial regression.

[0061] ‌Model Training‌: The selected supervised learning algorithm is trained using the training set data, and the performance of the model is optimized by adjusting the parameters and structure of the model.

[0062] ‌Model Evaluation and Optimization‌: Use the validation set data to evaluate the trained model, and evaluate the performance of the model by calculating indicators such as accuracy, recall, and F1 score. Further optimize and adjust the model based on the evaluation results.

[0063] Model validation is done by the administrator himself.

[0064] 5. Feature Correlation Analysis ‌Feature Importance Evaluation‌: Using the trained supervised learning model, evaluate the importance of each feature to the model's prediction results. This can be done by calculating the importance score of the feature or using a feature selection algorithm.

[0065] ‌Correlation Analysis‌: Based on the results of feature importance assessment, the correlation between each feature is analyzed. For example, correlation analysis, cluster analysis and other methods can be used to reveal the internal connection and mutual influence between features.

[0066] ‌Visual display‌: By drawing feature importance diagrams, correlation network diagrams, etc., the correlation relationship and importance distribution between features can be intuitively displayed, providing strong data support for energy storage system status supervision.

[0067] In summary, using supervised learning algorithms to extract data features and their correlations in each set of data in energy storage system state supervision is a complex and systematic process, which requires the comprehensive use of multiple steps and methods such as data preprocessing, feature selection and extraction, data labeling and training set construction, supervised learning model training and optimization, and feature correlation analysis.

[0068] In this aspect, by extracting data from big data through supervised learning algorithms, a feature set consisting of state feature values ​​and policy keywords can be constructed. Subsequently, a machine learning model, such as a random forest model, is used to train and learn the features in the feature set, so that the model can train and learn the relationship between policy keywords corresponding to different state feature values. The subsequent model can perform state recognition and output the matched policy keywords, and use the policy keywords to retrieve the corresponding reactive power compensation operation and maintenance strategy. The retrieval can be handed over to, for example, an LLM large language model to retrieve the reactive power compensation operation and maintenance strategy containing the corresponding policy keywords, and output it to the controller, which executes the operation and maintenance strategy on the corresponding storage device and performs reactive power compensation, so as to achieve stable operation of the power grid.

[0069] A large number of reactive power compensation operation and maintenance strategies can be pre-stored in the database, or historical operation and maintenance strategies can be used as a strategy library to provide a database retrieval basis for the output of the model.

[0070] When constructing the above features, the state feature values ​​corresponding to each strategy can also be expanded and processed, and the state feature values ​​corresponding to each strategy can be drifted up and down by a certain value to generate a state feature range value. For example, the charging current value of 40A is drifted to 37.5-42.5A. As long as the charging and discharging current values ​​meet this state feature range value, an operation and maintenance strategy will be used for processing, avoiding the drawbacks of excessive classification recognition, increased computing power share, and low recognition accuracy in the recognition of individual feature values. By identifying the range value, the model can improve the supervision range and recognition accuracy of the state data.

[0071] Preferably, S2, the host computer inputs the state data into a preset state AI supervision model, identifies the state characteristic value in the state data through the state AI supervision model and outputs a reactive power compensation operation and maintenance strategy matching the state characteristic value, including: Receive and identify the basic information of the status data reported by the energy storage system coordination controller and bind it to the device ID corresponding to the energy storage device; The state data is input into the state AI supervision model, and the state AI supervision model identifies the state feature value in the state data and determines whether there is a policy keyword matching the state feature value: If yes, extract the strategy keywords, retrieve the corresponding reactive power compensation operation and maintenance strategy according to the strategy keywords and output it; Otherwise, continue monitoring.

[0072] The model can identify whether the corresponding state characteristic value requires reactive compensation. If the state characteristic value that requires reactive compensation is extracted and identified in the state data of the current device, the AI ​​model is used to predict and match the output of the policy keywords corresponding to the state characteristic value (here, avoid directly outputting the corresponding reactive compensation operation and maintenance instructions to reduce the operating pressure of the model, and instead output the corresponding policy retrieval and send it to the policy library for execution, and find and output the reactive compensation operation and maintenance strategy containing the policy keywords).

[0073] For example, here, you can let the LLM large language model (through the backend LLM API interface, request call) perform the search, for example, you can refer to the following steps: First, it is necessary to identify the strategy keywords and prepare a relevant retrieval database or knowledge base (the original strategy stored in the background or a separate strategy library that stores a large number of reactive power compensation operation and maintenance strategies). This database or knowledge base should contain various operation and maintenance strategies and their corresponding keywords or tags.

[0074] ‌Prepare strategic keywords and database‌: Determine the strategic keywords to be searched, which should be closely related to the operation and maintenance strategy.

[0075] Establish a database or knowledge base containing various operation and maintenance strategies and their keywords or tags to ensure the accuracy and completeness of the data.

[0076] ‌Build a retrieval system‌: Utilize existing search engine technology or deep learning technology, such as keyword-based retrieval, content-based retrieval, or Transformer-based retrieval models, to build an efficient retrieval system.

[0077] This retrieval system should be able to quickly find relevant operation and maintenance strategies in the database based on strategy keywords.

[0078] ‌Combined with LLM large language model and retrieval system‌: Combine the LLM large language model with the retrieval system to achieve retrieval enhancement generation.

[0079] When a strategy keyword is entered, the retrieval system will first retrieve the operation and maintenance strategy information related to the keyword from the database.

[0080] The LLM large language model will then rearrange and combine this information to generate an operation and maintenance strategy text output that meets the requirements.

[0081] ‌Optimization and Evaluation‌: According to the needs of actual applications, the combination of LLM large language model and retrieval system is optimized to improve the accuracy and efficiency of retrieval.

[0082] Various evaluation indicators can be used to evaluate the performance of the system, such as accuracy, recall, etc., so as to continuously optimize and improve it.

[0083] Output operation and maintenance strategy: Finally, the operation and maintenance strategy text generated by the LLM large language model is output to the user for reference and use.

[0084] Through the above steps, the goal of allowing the LLM large language model to search the library based on strategy keywords and output the corresponding operation and maintenance strategy can be achieved.

[0085] like Figure 5 As shown, the host computer of the present invention can manage several energy storage devices in the energy storage power grid system through the controller, and the background can build the operation and maintenance files of the corresponding energy storage devices, and record the results of each sampling and operation and maintenance supervision to facilitate subsequent supervision and management.
