The system central processing module is used for the information text instructions output by each module in the central control system, and the user information terminal is an information output device for receiving the energy consumption optimization management system.

[0075] The intelligent information collection terminal collection module responds to the intelligent information collection terminal deployed in the energy consumption detection area to obtain real-time energy consumption data.

[0076] Specifically, the energy consumption optimization management system responds to multiple intelligent information collection terminals pre-set in the energy consumption detection area, collects information from multiple energy consumption devices corresponding to the target energy consumption monitoring area, and the intelligent information collection terminals include but are not limited to current transformers, voltage sensors, water flow sensors, thermal gas mass flow meters, etc.; converts the data information obtained by the intelligent information collection terminals into digital signals; and transmits the digital signals by building a data transmission link with the help of LoRa wireless communication technology.

[0079] The energy data preprocessing module is used to perform preprocessing operations on the real-time energy consumption data transmitted by the intelligent information collection terminal collection module, and the preprocessing operation is used to obtain the key energy calibration group corresponding to the real-time energy consumption data.

[0080] Specifically, after acquiring the real-time energy consumption data transmitted by the collection module of the intelligent information collection terminal, the energy consumption optimization management system preprocesses the real-time energy consumption data to obtain multiple key energy information corresponding to the real-time energy consumption data, namely, the key energy calibration group.

[0081] In a possible implementation, the preprocessing step includes:

[0084] A2: Data completion: Perform data completion operations based on missing real-time energy consumption data. The completion operation is used to complete the real-time energy consumption data that is not an outlier.

[0085] In this embodiment, when the real-time energy consumption data is missing in the power consumption data within the time period, and there are valid data points before and after the missing part, linear interpolation is used to complete it. The power at time t1 is 100kW, and the power at time t3 is 120kW. The missing data corresponding to time t2, the completion value is (100+(120-100) / (t3-t1)*(t2-t1))kW;

[0086] A3: Feature extraction and association analysis: Feature extraction and association analysis operations are performed on the cleaned and completed real-time energy consumption data. The feature extraction and association analysis operations are used to obtain energy consumption indicators, statistical indicators, and correlation coefficients corresponding to the real-time energy consumption data. Energy consumption indicators are key performance parameters corresponding to different types of energy consumption data. Statistical indicators are combinations of different types of energy data. Statistical indicators include the mean, variance, maximum value, and minimum value corresponding to each energy consumption indicator combination.

[0088] A4: Data standardization processing: The extracted key energy information is processed using the Z-score standardization method to generate a key energy calibration group.

[0089] The intelligent prediction module is used to obtain an intelligent prediction model, and obtain energy consumption characteristics according to the key energy calibration group transmitted by the intelligent prediction model through the energy data preprocessing module.

[0090] Specifically, the intelligent prediction model is a pre-constructed learning model. By inputting the key energy calibration group transmitted by the energy data preprocessing module into the intelligent prediction model, the intelligent prediction model obtains energy consumption characteristics according to the key energy calibration group transmitted by the energy data preprocessing module.

[0092] Specifically, in industrial plants, the intelligent prediction model adopts a deep learning multi-scale LSTM algorithm, performs time sorting based on key energy information, and obtains energy consumption trends through multiple LSTM models; obtains multiple time scales, where the time scale is multiple unit time periods corresponding to the prediction time; divides multiple LSTM models based on the time scale, and obtains multiple energy consumption features corresponding to the multiple LSTM models; uses a weighted average method to fuse multiple LSTM models of different time scales, uses multiple energy consumption features as fusion vectors according to weighted results, and obtains energy consumption features through activation functions. The energy consumption features include predicted energy consumption values, energy consumption trends, and evaluation indicators corresponding to the intelligent evaluation model.

[0093] In one possible implementation, obtaining energy consumption characteristics includes: measuring the degree of difference between the predicted energy consumption value and the actual energy consumption data through a loss function corresponding to the intelligent prediction model, the loss function includes mean square error and mean absolute error; based on the degree of difference calculated by the loss function, the prediction parameters corresponding to the intelligent prediction model are iteratively updated through an optimization algorithm, the optimization algorithm includes but is not limited to stochastic gradient descent, Adam, etc., and the prediction parameters are weights and bias parameters dynamically adjusted in the intelligent optimization model.

[0094] Specifically, the multi-scale LSTM model captures time series information at different levels by using LSTM models of multiple time scales at the same time. According to the importance of time scale to energy consumption characteristics, the prediction parameters corresponding to the LSTM models of multiple time scales are determined through the fully connected layer; based on the i-th predicted energy consumption value Ea i and the actual energy consumption value of the ith Calculate the root mean square error coefficient ER1 between the predicted energy consumption value and the actual energy consumption data, which is specifically expressed as:

[0098]

[0099] Wherein, N represents the total number of test points in the test evaluation set for the intelligent prediction model, and i represents the index of the test point in the test evaluation set.

[0100] In a possible implementation, obtaining energy consumption characteristics includes: performing an evaluation operation on the predicted energy consumption value corresponding to the intelligent prediction model according to the degree of difference obtained by calculating multiple loss functions, and the evaluation operation is to obtain evaluation indicators corresponding to the prediction parameters of the optimized intelligent prediction model.

[0101] Specifically, when the root mean square error coefficient ER1 between the predicted energy consumption value and the actual energy consumption data is lower than the preset error threshold, the preset error threshold is set to 0.1, and the determination coefficient ER2 between the predicted energy consumption value and the actual energy consumption data belongs to the high-level standard, and the specific value corresponding to the high-level standard is 0.8, then the prediction result of the intelligent prediction model is evaluated to be highly accurate, and the prediction parameters corresponding to the intelligent prediction model do not need to be optimized through the optimization algorithm.

[0102] The multi-objective optimization scheduling module is based on the real-time energy consumption data transmitted by the intelligent information collection terminal acquisition module and the energy consumption characteristics transmitted by the intelligent prediction module.
