As an important energy storage method, electrochemical energy storage power stations play an important role in the power system, which can improve the stability, flexibility and reliability of the power grid and promote the large-scale application of renewable energy. However, there are a series of safety hazards in the operation of electrochemical energy storage power stations, such as overcharging, over-discharging, short circuit and other problems. Therefore, it is particularly important to carry out safety monitoring of electrochemical energy storage power stations.

[0003] However, traditional electrochemical energy storage power station safety monitoring solutions usually rely on manual inspections and regular testing, which cannot achieve real-time and comprehensive power station monitoring and are prone to ignoring potential safety risks. In addition, some existing electrochemical energy storage power station safety monitoring methods monitor the safety parameter data in the power station and compare it with the predetermined threshold to determine whether there is a safety problem. However, this method can only rely on threshold monitoring of single data for risk warning, lacks intelligent analysis of complex situations, and results in limited ability to identify and warn of abnormal situations in electrochemical energy storage power stations.

[0040] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0041] Figure 1 It is a block diagram of a smart safety monitoring system for an electrochemical energy storage power station according to an exemplary embodiment.

[0042] like Figure 1 As shown, the system 100 includes:

[0043] The electrochemical energy storage power station parameter acquisition module 101 is used to monitor the key parameters of the electrochemical energy storage power station in real time through a sensor network to obtain a time series of the key parameters, wherein the key parameters include battery voltage, battery current and battery temperature;

[0044] The power station parameter data time series integration module 102 is used to integrate the time series of the key parameters according to the parameter sample dimensions to obtain the time series of the battery voltage, the time series of the battery current and the time series of the battery temperature;

[0045] A power station parameter time series feature extraction module 103, used to perform sequence encoding on the time series of the battery voltage, the time series of the battery current and the time series of the battery temperature to obtain a battery voltage time series associated implicit feature vector, a battery current time series associated implicit feature vector and a battery temperature time series associated implicit feature vector;

[0046] A battery voltage-battery current time series feature interactive fusion module 104 is used to process the battery voltage time series associated implicit feature vector and the battery current time series associated implicit feature vector using a battery current-voltage time series interactive fusion module to obtain a battery voltage-battery current time series interactive fusion feature vector;

[0047] The power station operation status abnormality detection module 105 is used to perform battery temperature semantic mapping reasoning based on the battery voltage-battery current time series interactive fusion feature vector to obtain a battery temperature semantic reasoning mapping feature vector, and determine whether the operation status of the electrochemical energy storage power station is abnormal based on the distance between the battery temperature semantic reasoning mapping feature vector and the battery temperature time series associated implicit feature vector.

[0048] In response to the above technical problems, in the technical solution of this application, an intelligent safety monitoring system for electrochemical energy storage power stations is proposed, which can monitor and collect key parameters of electrochemical energy storage power stations in real time through a sensor network, including battery voltage, battery current and battery temperature, and introduce artificial intelligence-based data processing and analysis algorithms at the back end to perform time-series collaborative correlation analysis of these key parameters, so as to detect and judge abnormalities in the operating status of electrochemical energy storage power stations. In this way, intelligent safety monitoring of electrochemical energy storage power stations can be achieved, thereby improving the safety and operating efficiency of power stations and reducing potential risks and the possibility of accidents.

[0049] Specifically, in the technical solution of the present application, first, the key parameters of the electrochemical energy storage power station are monitored in real time through a sensor network to obtain a time series of the key parameters, wherein the key parameters include battery voltage, battery current and battery temperature. It should be understood that sensor network technology is the basis for realizing intelligent monitoring of electrochemical energy storage power stations. By deploying sensors at key locations, important parameters such as battery voltage, current and temperature can be monitored in real time to obtain accurate electrochemical energy storage power station operation data. These data can not only reflect the real-time operating status of the power station, but also provide a basis for subsequent safety analysis and early warning.

[0050] Next, considering that the key parameter data of the electrochemical energy storage power station, such as battery voltage, battery current and battery temperature, will continue to change over time in the time dimension, that is, these key parameter data have dynamic change laws and characteristics of time series. Based on this, in order to better analyze and understand the time series characteristics and correlations of these key parameters, so as to achieve comprehensive monitoring and analysis of the operating status of the power station, in the technical solution of the present application, it is necessary to integrate the time series of the key parameters according to the parameter sample dimension to obtain the time series of battery voltage, the time series of battery current and the time series of battery temperature. In this way, the time series information of the battery voltage, battery current and battery temperature in the key parameters in the time dimension can be integrated, and the position information of these key parameters in the time series can be retained, which is conducive to more fully capturing the dynamic characteristics and change laws of the battery voltage, current and temperature in the time series, so as to detect abnormal conditions in time.

[0051] Then, in order to capture the time series pattern and characteristic information of the key parameters of the electrochemical energy storage power station in the time dimension, the time series of the battery voltage, the time series of the battery current and the time series of the battery temperature are passed through the sequence encoder based on the RNN model to obtain the battery voltage time series associated implicit feature vector, the battery current time series associated implicit feature vector and the battery temperature time series associated implicit feature vector. Through the processing of the sequence encoder based on the RNN model, the time series association and dynamic change characteristics of the battery voltage, battery current and battery temperature in the time dimension can be effectively captured, so as to reflect the law and trend of these key parameters changing over time, and provide strong data support for the subsequent electrochemical energy storage power station operation status analysis and anomaly detection tasks.

[0052] In one embodiment of the present disclosure, the power station parameter timing feature extraction module is used to: pass the time series of the battery voltage, the time series of the battery current and the time series of the battery temperature through a sequence encoder based on an RNN model to obtain the battery voltage timing-related implicit feature vector, the battery current timing-related implicit feature vector and the battery temperature timing-related implicit feature vector.

[0053] It should be understood that battery current and voltage are two very important parameters in the battery's electrochemical energy storage system, and the timing correlation relationship between them can reveal the internal state and characteristics of the battery, thereby reflecting the battery temperature timing semantics. Based on this, in order to more accurately utilize the timing synergistic correlation characteristics between the battery current and voltage to perform timing semantic reasoning of the battery temperature, it is necessary to more comprehensively characterize the operating state and dynamic characteristics of the battery system. Specifically, in the technical solution of the present application, the battery current-voltage timing interaction fusion module is further used to process the battery voltage timing association implicit feature vector and the battery current timing association implicit feature vector to obtain a battery voltage-battery current timing interaction fusion feature vector. By applying the battery current-voltage timing interaction fusion module, the battery voltage timing characteristics and the battery current timing characteristics can be interactively fused, so that the timing correlation characteristics and dynamic change laws between the battery voltage and current can be better captured, so as to more comprehensively describe the operating state of the battery system, and provide more useful information and support for subsequent battery temperature timing semantic reasoning and energy storage power station operating state detection.

[0054] In particular, in a specific example of the present application, the battery current-voltage timing interaction fusion module is used to process the battery voltage timing-related implicit feature vector and the battery current timing-related implicit feature vector using the following timing feature interaction fusion formula to obtain the battery voltage-battery current timing interaction fusion feature vector;

[0055] The interactive fusion formula of the time series features is:

[0056]

[0057] in, is the eigenvalue of the ith position in the implicit eigenvector associated with the battery voltage time series, is the eigenvalue of the ith position in the implicit eigenvector associated with the battery current timing, α and β are adjustment hyperparameters, and v ci is the eigenvalue of the i-th position in the battery voltage-battery current time series interactive fusion eigenvector.

[0058] In one embodiment of the present disclosure, the battery voltage-battery current timing feature interactive fusion module includes: a battery voltage-battery current timing association encoding unit, which is used to multiply the battery voltage timing association implicit feature vector and the battery current timing association implicit feature vector by position point to obtain a battery voltage-battery current timing association feature vector; and an association feature multi-modulation optimization unit, which is used to perform multi-modulation optimization on the battery voltage-battery current timing association feature vector to obtain the battery voltage-battery current timing interactive fusion feature vector.

[0059] Further, in one embodiment of the present disclosure, the associated feature multi-modulation optimization unit includes: a linear term modulation subunit, which is used to perform linear term modulation on each position feature value in the battery voltage-battery current timing interaction fusion feature vector to obtain a linear term modulated battery voltage-battery current timing association feature vector; a quadratic term modulation subunit, which is used to perform quadratic term modulation on each position feature value in the battery voltage-battery current timing interaction fusion feature vector to obtain a quadratic term modulated battery voltage-battery current timing association feature vector; a multi-modulation subunit, which is used to add the linear term modulated battery voltage-battery current timing association feature vector and the quadratic term modulated battery voltage-battery current timing association feature vector by position to obtain a multi-modulated battery voltage-battery current timing association feature vector; a constant term modulation addition subunit, which is used to perform constant plus one modulation on each position feature value in the multi-modulated battery voltage-battery current timing association feature vector to obtain the battery voltage-battery current timing interaction fusion feature vector.

[0060] Among them, the first-order modulation subunit includes: an exponential modulation secondary subunit, which is used to calculate the exponential function value raised to the power of the eigenvalues ​​of each position in the battery voltage-battery current timing correlation characteristic vector to obtain the exponentially modulated battery voltage-battery current timing correlation characteristic vector; and a first parameter adjustment secondary subunit, which is used to multiply the exponentially modulated battery voltage-battery current timing correlation characteristic vector by a first predetermined adjustment hyperparameter to obtain the first-order modulation battery voltage-battery current timing correlation characteristic vector.

[0061] The quadratic term modulation subunit includes: an exponential quadratic modulation secondary subunit, which is used to calculate an exponential function value with the square of the characteristic value of each position in the battery voltage-battery current timing correlation characteristic vector as a power to obtain an exponential quadratic modulation battery voltage-battery current timing correlation characteristic vector; and a second parameter adjustment secondary subunit, which is used to multiply the exponential quadratic modulation battery voltage-battery current timing correlation characteristic vector by a second predetermined adjustment hyperparameter to obtain the quadratic term modulation battery voltage-battery current timing correlation characteristic vector.

[0062] Furthermore, considering that the battery voltage-battery current timing interaction fusion feature vector contains the timing interaction fusion feature information between the battery voltage timing features and the battery current timing features, this feature information can reflect the state and dynamic characteristics of the battery system. Therefore, a semantic reasoning mapper can be used to learn and model the deep relationship between battery temperature and voltage and current, and use this relationship to map the timing interaction fusion semantics of the battery voltage and current into the timing semantic space of the battery temperature, thereby obtaining the mapping reasoning semantics of the battery temperature. Specifically, in the technical solution of the present application, the battery voltage-battery current timing interaction fusion feature vector is passed through a decoder-based battery temperature semantic reasoning mapper to obtain a battery temperature semantic reasoning mapping feature vector.

[0063] Then, the Hamming distance between the battery temperature semantic reasoning mapping feature vector and the battery temperature time series associated implicit feature vector is calculated to measure the similarity between the battery temperature time series mapping semantic reasoning feature and the battery temperature time series associated implicit feature. That is to say, by comparing the Hamming distance between the battery temperature reasoning mapping feature vector and the original time series associated implicit feature vector, the difference between the battery temperature reasoning semantics and the actual monitoring situation can be evaluated, thereby helping to diagnose the fault of the battery system. Furthermore, based on the comparison between the Hamming distance and the predetermined threshold, it is determined whether the operating state of the electrochemical energy storage power station is abnormal. In particular, in response to the Hamming distance being greater than the predetermined threshold, it is determined that the operating state of the electrochemical energy storage power station is abnormal. In this way, hidden safety hazards and problems can be discovered in time through the time series analysis of the key parameters of the electrochemical energy storage power station and the comparison of the differences in battery temperature, avoiding serious safety accidents caused by the hysteresis of the response, thereby improving the safety and operating efficiency of the power station and reducing the possibility of potential risks and accidents.

[0064] In one embodiment of the present disclosure, the power station operation state abnormality detection module includes: a battery temperature semantic mapping reasoning unit, which is used to pass the battery voltage-battery current timing interactive fusion feature vector through a decoder-based battery temperature semantic reasoning mapper to obtain the battery temperature semantic reasoning mapping feature vector; a battery temperature timing feature comparison unit, which is used to calculate the Hamming distance between the battery temperature semantic reasoning mapping feature vector and the battery temperature timing associated implicit feature vector; an operation state abnormality judgment unit, which is used to determine whether the operation state of the electrochemical energy storage power station is abnormal based on the comparison between the Hamming distance and a predetermined threshold.

[0065] Furthermore, in one embodiment of the present disclosure, the electrochemical energy storage power station intelligent safety monitoring system also includes a training module for training the RNN model-based sequence encoder, the battery current-voltage timing interaction fusion module, and the decoder-based battery temperature semantic reasoning mapper. The training module includes: a training electrochemical energy storage power station parameter acquisition unit, which is used to monitor the training key parameters of the electrochemical energy storage power station in real time through the sensor network to obtain the time series of the training key parameters, wherein the training key parameters include the training battery voltage, the training battery current and the training battery temperature; a training power station parameter data time series integration unit, which is used to integrate the time series of the training key parameters according to the parameter sample dimension to obtain the time series of the training battery voltage, the time series of the training battery current and the time series of the training battery temperature; a training power station parameter time series feature extraction unit, which is used to respectively perform sequence encoding on the time series of the training battery voltage, the time series of the training battery current and the time series of the training battery temperature to obtain the training battery voltage time series associated implicit feature vector, the training battery current time series associated implicit feature vector and the training battery temperature time series associated implicit feature vector; a training battery voltage-battery current time series feature interactive fusion unit, which is used to use the battery The current-voltage timing interaction fusion module processes the training battery voltage timing-associated implicit feature vector and the training battery current timing-associated implicit feature vector to obtain a training battery voltage-battery current timing interaction fusion feature vector; the training battery temperature semantic mapping reasoning unit is used to pass the training battery voltage-battery current timing interaction fusion feature vector through the decoder-based battery temperature semantic reasoning mapper to obtain a training battery temperature semantic reasoning mapping feature vector; the training battery temperature timing feature comparison unit is used to calculate the specific loss function value between the training battery temperature semantic reasoning mapping feature vector and the training battery temperature timing-associated implicit feature vector; the training unit is used to train the RNN model-based sequence encoder, the battery current-voltage timing interaction fusion module and the decoder-based battery temperature semantic reasoning mapper based on the specific loss function value, and in each iterative training, the training battery temperature semantic reasoning mapping feature vector is optimized.

[0066] In the technical solution of the present application, the training battery temperature semantic reasoning mapping feature vector is obtained by performing feature timing interactive fusion encoding on the training battery voltage timing-related implicit feature vector and the training battery current timing-related implicit feature vector and decoding by a decoder-based battery temperature semantic reasoning mapper, that is, the training battery temperature semantic reasoning mapping feature vector has a complex multi-domain and multi-modal timing feature association representation dimension of the encoding domain-decoding domain. Therefore, the feature expression effect under the complex multi-domain and multi-modal timing feature association representation dimension of the encoding domain-decoding domain is improved during the model iteration process.

[0067] Based on this, the applicant of the present application optimizes the training battery temperature semantic reasoning mapping feature vector, for example, denoted as V, during each iteration of the model, which is expressed as follows: in each iteration training, the training battery temperature semantic reasoning mapping feature vector is optimized to obtain the optimized training battery temperature semantic reasoning mapping feature vector; wherein the optimization formula is:

[0068]

[0069] Among them, μ, σ and v max They are the feature sets v i ∈V, log is the logarithmic function with base 2, and α is the weight hyperparameter, V is the training battery temperature semantic reasoning mapping feature vector, V′ is the optimized training battery temperature semantic reasoning mapping feature vector, v max -1 is the feature set v i ∈V is the inverse of its maximum value, represents positional addition, represents positional subtraction, and ⊙ represents positional multiplication.

[0070] Here, we use an interactive representation containing probability statistics features represented by mean μ and standard value σ and v as a latent variable feature. i and v maxThe short sequence of the distribution interaction representation is used as the sub-manifold potential motif under the complex manifold network of the training battery temperature semantic reasoning mapping feature vector V, and the obtained potential motif feature information pattern and feature distribution pattern of the training battery temperature semantic reasoning mapping feature vector V are used as its global structure inference unit, so as to reconstruct the complex manifold structure of the training battery temperature semantic reasoning mapping feature vector V in the form of a global structure potential motif dictionary based on connection, so as to improve the generation and evolution understanding ability of the model in the iterative process for the manifold structure corresponding to the temporal correlation feature of the complex multi-domain and multi-modal temporal feature association representation dimension of the encoding domain-decoding domain, and improve the feature expression effect under the complex multi-domain and multi-modal temporal feature association representation dimension of the encoding domain-decoding domain during the model iteration process. In this way, the calculation accuracy of the Hamming distance between the training battery temperature semantic reasoning mapping feature vector and the battery temperature temporal association implicit feature vector is improved. In this way, the safety monitoring of the electrochemical energy storage power station can be carried out more accurately, thereby improving the safety and operation efficiency of the power station and reducing the possibility of potential risks and accidents.

[0071] In summary, the above scheme is adopted to monitor and collect the key parameters of the electrochemical energy storage power station in real time through the sensor network, including battery voltage, battery current and battery temperature, and introduce artificial intelligence-based data processing and analysis algorithms at the back end to perform time series collaborative correlation analysis of these key parameters, so as to detect and judge the operating status of the electrochemical energy storage power station.
