It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings:
[0045] Example 1
[0046] refer to Figure 1 The method for equivalence of day-ahead scheduling potential for industrial flexible loads as described in this invention includes the following steps:
[0047] 1) Considering the complementary characteristics of flexible industrial loads, aggregate flexible loads for small and medium-sized industries;
[0048] The specific operation of step 1) is as follows:
[0049] 11) Collect load data from smart meters, sensors and monitoring equipment in industrial enterprises in real time, clean and process the collected load data to ensure the accuracy and availability of the data, and integrate and standardize the load data from different enterprises for subsequent analysis and aggregation.
[0050] 12) For the characteristics of flexible industrial load regulation, such as regulation capacity, regulation delay, and regulation cost, the Max-min normalization method is used to normalize them. A larger normalized result indicates better performance of the flexible industrial load in this aspect. The normalization formula is:
[0051]
[0052] q qi For the normalized industrial flexible load characteristics, q i For the original industrial flexible load characteristics, min 1≤j≤n {q i} represents the lower limit of the flexible load characteristics of industry, max 1≤j≤n {q i} represents the upper limit of the industrial flexible load characteristics.
[0053] 13) For the normalized industrial flexible load adjustment characteristics, quantify them into Boolean values, where 1 indicates the presence of a certain characteristic and 0 indicates the absence of a certain characteristic. Then, based on the characteristic values of each industrial flexible load, construct the industrial flexible load complementary coordination matrix Q. k for:
[0054]
[0055] Among them, the industrial flexible load complementary coordination matrix Q k Each column in the matrix corresponds to an industrial flexible load, such as energy storage, electrolytic aluminum, and industrial furnaces. The industrial flexible load complementarity coordination matrix Q... k Each row in the table represents the quantified, multi-dimensional adjustment characteristics of the industrial flexible load, such as adjustment capacity, adjustment delay, and adjustment cost.
[0056] 14) Based on the flexible load complementarity coordination matrix Q of each industry k To aggregate flexible industrial loads, machine learning algorithms such as K-means clustering and nearest neighbor algorithm can be used.
[0057] 2) Obtain interaction data between industrial flexible loads and the power grid, and construct a day-ahead equivalent scheduling dataset for industrial flexible loads;
[0058] The specific operation of step 2) is as follows:
[0059] 21) Collect interaction data between industrial flexible loads and the power grid through power companies, energy trading markets or related institutions. The interaction data includes the declared volume and declared price information of industrial flexible loads in the day-ahead ancillary service (peak shaving) market, and the production plan of industrial flexible loads.
[0060] 22) Preprocess the interactive data, including data cleaning, outlier removal, and missing data filling.
[0061] 23) Based on the preprocessed interactive data, construct the input information set, in which the interactive data is integrated and divided according to the preset time interval and time window. The appropriate time granularity, such as hourly, daily or weekly, can be selected according to the needs and actual situation.
[0062] 24) Considering the load demand of the power grid, the price signals of the energy market, and the flexibility of industrial loads, different flexible industrial load dispatching instructions are randomly generated. The flexible industrial load dispatching instructions are input into the flexible industrial load production process optimization model to verify whether the flexible industrial load dispatching instructions can be executed. The verification results are used as labels to construct an equivalent dispatching label data set. Based on the equivalent dispatching label data set and the input information set, an industrial flexible load day-ahead equivalent dispatching dataset is constructed.
[0063] 3) Establish a data-driven industrial flexible load equivalent scheduling model and determine the parameters of the data-driven industrial flexible load equivalent scheduling model.
[0064] The specific operation of step 3) is as follows:
[0065] 31) Considering day-ahead scheduling operations, interactive data structures, and production regulation characteristics, establish an equivalent scheduling model for flexible industrial loads, similar to generating units or energy storage systems:
[0066]
[0067] in, M represents the load power of the industrial flexible load k. k For the corresponding coefficient matrix, N k These are the reported parameters to be determined for the equivalent model, corresponding to power, ramp, and energy boundaries.
[0068] 32) Based on the equivalent scheduling tag data set, generate an initial equivalent power set containing all executable industrial flexible load scheduling instructions, and use a neural network to predict the adjustment direction and distance of the power set in order to eliminate power points in the power set that cannot be scheduled. The neural network is an estimating neural network.
[0069]
[0070] Among them, Ω k Let be the power set, β be the scaling factor, and z be the displacement factor.
[0071] 33) Based on the adjusted distance of the power set, an offline neural network model is trained to determine the parameters of the data-driven industrial flexible load equivalent scheduling model. The trained neural network model is used as the equivalent neural network. Specifically, the day-ahead equivalent scheduling dataset of industrial flexible load obtained in step 2) is input, and the regularization term of the loss function of the equivalent neural network is adjusted according to the distance output set of the estimation neural network. Through stochastic gradient descent, the weight parameters of the equivalent neural network are continuously adjusted, and the output is the parameters of the optimized equivalent model.
[0072]
[0073] Where, θ t Here are the network weight parameters to be updated, where δ is the learning rate and ε is the smoothing coefficient. and is the mean of the first and second moments of the gradient.
[0074] 34) Use the PyTorch deep learning library to build and train a deep learning model. Through multiple rounds of training, obtain converged results. Divide the input information set in step 2) into a test set and substitute it into the equivalent neural network. Perform inverse normalization on the output of the equivalent neural network to obtain the parameters of the data-driven industrial flexible load equivalent scheduling model.
[0075] 4) Establish and solve the day-ahead dispatch model of the power grid that incorporates the data-driven industrial flexible load equivalent dispatch model.
[0076] The specific process of step 4) is as follows:
[0077] 41) Construct a day-ahead dispatch model for the power grid that includes power balance constraints, reserve capacity constraints, and cross-sectional capacity constraints.
[0078] 42) Embed the data-driven industrial flexible load equivalent scheduling model into the day-ahead power grid scheduling model. The constraints of this day-ahead power grid scheduling model are:
[0079]
[0080]
[0081]
[0082]
[0083]
[0084] in, This indicates that the k-th industrial flexible load selects the z-th adjustment scheme. These represent the actual / baseline power consumption of the k-th industrial flexible load in the t-th time period, respectively. These are the parameters for the industrial flexible load equivalent model.
[0085] 44) Use a solver to solve the day-ahead dispatch model of the power grid embedded with the data-driven industrial flexible load equivalent dispatch model to obtain the industrial flexible load dispatch plan, and perform industrial flexible load dispatch according to the industrial flexible load dispatch plan. The commercial solver can be cplex or gurobi.
[0086] It should be noted that this invention, by analyzing and utilizing the interaction data between industrial flexible loads and the power grid, aggregates industrial flexible loads under the regional power grid into dispatchable objects similar to generating units or energy storage for use by the upper-level power grid. This allows for more accurate prediction and assessment of the potential and flexibility of industrial loads. Furthermore, this invention combines data analysis, machine learning, and optimization techniques to establish an equivalent dispatch model for industrial flexible loads, achieving refined management and dispatch of loads. Simultaneously, it considers the actual conditions and energy supply strategies within the industrial flexible loads, ensuring that dispatch instructions issued by the upper-level power grid can be effectively executed by industrial users.
[0087] Example 2
[0088] In a provincial power grid, the aggregated industrial flexible load includes two types of self-provided generators with rated capacities of 350MW and 125MW, respectively. The maximum loads of electric arc furnaces and electrolytic cells (electrolytic aluminum) are 20.72MW and 735MW, respectively. Considering this invention, its equivalent dispatch potential model is as follows: Figure 2 As shown, the response cost-response power relationship of the equivalent model is as follows: Figure 3 As shown.
[0089] As can be seen, compared with the method of directly superimposing equipment parameters to equalize scheduling potential, this invention can more accurately describe the adjustment capability boundary of industrial flexible loads, ensuring that the power grid does not issue scheduling instructions that industrial flexible loads cannot execute. Figure 3 It can be seen that the equivalent model can achieve equal response power within a certain cost range, thereby improving the grid's flexible adjustment capability and its ability to absorb new energy sources while ensuring its own benefits.
