[0059] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0062] In the case of no conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0063] Please refer to Figure 1 , the present invention provides an artificial intelligence-based method for predicting the electricity carbon emissions of a smart park, and the method includes:

[0064] Step S1, obtain the external and internal purchased electricity activity data and direct electricity consumption data of the smart park, and calculate the carbon emissions of the externally purchased electricity and the direct electricity consumption in the smart park by using the electricity carbon emission accounting standard to obtain the total carbon emissions.

[0065] It should be explained that in the process of obtaining the total carbon emissions, based on the latest released international, national, and local provincial and municipal electricity carbon emission accounting standards, the electricity carbon emission accounting method and the reference value of the electricity carbon emission factor are determined, and an electricity carbon emission algorithm model for the externally purchased electricity during the operation and maintenance period of the smart park is constructed.

[0066] In the process of realizing the calculation of the total carbon emissions, it is necessary to construct a sample library for the artificial intelligence spatio-temporal prediction model of the electricity carbon emissions in the smart park. The goal of constructing the sample library is to collect sample data for predicting the electricity carbon emissions in different regions (spatial dimension) and different time periods (time dimension) in the smart park.

[0067] Collect electricity consumption data from various IoT weak current sensors deployed in the park, obtain the real-time electricity consumption data and historical energy consumption data of the equipment, calculate the electricity carbon emission data by selecting the corresponding electricity carbon emission factor. In addition, it is also necessary to collect the environmental parameter information in the park for assisting model prediction, including meteorological data such as temperature, humidity, wind speed, weather, and season, which may affect the electricity demand; in addition, the operation information of the park, such as weekdays, weekends, holidays, etc., all of which will have an impact on the electricity consumption pattern;

[0068] Step S2, construct a relationship model between the total carbon emissions and the energy consumption of the electrical equipment, predict the total electricity carbon emissions generated by the electrical equipment in the smart park under any operation strategy, and judge the emission efficiency corresponding to the total electricity carbon emissions.

[0069] In one embodiment, in the process of constructing a relationship model between the total carbon emissions and the energy consumption of electrical equipment, predicting the total carbon emissions of electrical equipment in the smart park under any operating strategy, and judging the emission efficiency corresponding to the total carbon emissions of electricity, the total carbon emissions and the energy consumption data of electrical equipment corresponding to the historical operation and maintenance process of the smart park can be obtained, and the dimensionality reduction and decoupling processing is performed on the electricity consumption data to obtain a number of main dimension vectors that are orthogonally distributed; based on the mean clustering technology, each main dimension vector is sequentially constrained, and the energy consumption conditions are randomly combined and generated, and the combined energy consumption level of the energy consumption conditions is analyzed in combination with the carbon emissions; according to the Pearson correlation coefficient between the main dimension vector and the comprehensive energy consumption level, the relationship model between the carbon emissions and the energy consumption of electrical equipment is obtained, and the functional relationship result between the carbon emissions and the energy consumption is generated; based on the feature selection algorithm and the Shapley additive explanation technology, the key factors affecting the energy consumption change are obtained under any operating strategy of the electrical equipment, and a numerical set is generated to predict the energy consumption value and judge the total carbon emissions of electricity; the carbon emission factor is used to analyze the duration corresponding to the complete discharge of the total carbon emissions of electricity, and the emission efficiency of the power supply equipment in the smart park is evaluated according to the duration result.

[0070] It should be noted that in the process of obtaining the relationship model between the carbon emissions and the energy consumption of electrical equipment, first, the historical operation and maintenance data of the smart park are obtained, including the total carbon emissions (calculated by the electricity carbon emission factor) and the energy consumption data related to all electrical equipment in the park. After obtaining the original data, it is necessary to clean the data, process missing values, outliers, and problems with inconsistent data formats. For the energy consumption data, it is usually necessary to organize it according to the time granularity (such as hourly, daily, or monthly).

[0071] In order to simplify the electricity consumption data and remove redundant information, dimensionality reduction methods such as principal component analysis (PCA) or independent component analysis (ICA) can be used. PCA can map multi-dimensional data to a lower-dimensional space and retain most of the data variance.

[0072] The specific steps are as follows: first, standardize the energy consumption data so that the mean of each feature is 0 and the standard deviation is 1; calculate the covariance matrix of the standardized data to reflect the correlation between each feature; perform eigenvalue decomposition on the covariance matrix to obtain eigenvalues and eigenvectors, and the eigenvectors are the main dimensions; select the first few principal components (i.e., the main dimension vectors with larger eigenvalues) to represent the energy consumption data; the main dimension vectors generated by PCA are orthogonal, that is, uncorrelated, which provides a basis for subsequent analysis; a number of main dimension vectors are obtained, representing different aspects of the electricity consumption data, and these vectors are orthogonal, that is, the vectors are numerically independent of each other, avoiding information redundancy.

[0073] Taking each principal dimension vector as a data point, perform mean clustering analysis in multiple dimensions to find data groups with similarity in energy consumption data. For example, K-means clustering can be performed according to the numerical characteristics of each principal dimension vector, and devices with similar energy consumption patterns can be classified into one category.

[0074] At the same time, select the optimal K value, that is, the number of clusters, according to experience or the Silhouette Method. Meanwhile, randomly select K center points. According to the distance metric of the principal dimension vector (such as Euclidean distance), assign each data point to the closest center point. Based on the data points in each cluster, recalculate the center point of each cluster until the clustering result converges. Based on the result of mean clustering, randomly combine different categories of energy consumption patterns (that is, each category represents an energy consumption condition), and combine these conditions with carbon emissions according to the power carbon emission data. Each combination will generate a specific energy consumption level and correspond to a carbon emission. Combine the carbon emissions of each energy consumption condition with the comprehensive energy consumption level (that is, the sum of energy consumption in all dimensions) for analysis to help understand the energy consumption under different device configurations and operating modes and its impact on carbon emissions.

[0075] The Pearson correlation coefficient is used to measure the linear correlation between two variables, and its value ranges from -1 to 1. The closer the value is to 1, the stronger the positive correlation. At the same time, use the Pearson correlation coefficient to calculate the correlation between the principal dimension vector (energy consumption) and the comprehensive energy consumption level to help understand which principal dimensions have a greater impact on the total energy consumption and reveal the relationship between energy consumption changes and carbon emissions.

[0076] Pearson correlation coefficient ω Calculation formula: ;

[0077] In the formula, x i and y i represent the values of the principal dimension vector and the comprehensive energy consumption level respectively, and represent the means of the corresponding variables.

[0078] According to the calculated Pearson correlation coefficient, a relationship model between carbon emissions and the energy consumption of electrical equipment can be constructed. For example, if the correlation between the principal dimension and carbon emissions is strong, it indicates that this dimension plays a key role in controlling carbon emissions. Using these correlations, a function model can be generated to describe the quantitative relationship between carbon emissions and energy consumption. If the linear correlation is strong, it can be represented by a linear regression model.

[0079] In one embodiment, in the process of obtaining the key factors affecting the energy consumption change of an electrical device under any operating strategy based on a feature selection algorithm and Shapley additive explanation technology, generating a numerical set to predict the energy consumption value, and judging the total power carbon emission, the influencing factors including the load fluctuation mode, environmental impact mode, and operating cycle mode can be selected according to the operating strategy of the electrical device, and the total influence component value of the influencing factors on the electrical device can be judged; the characteristic information of the total influence component value is obtained, and the characteristic information is used as the feature set, and the total influence component value is used as the data set to initialize the number of iterations and the number of selected neighbors; a set of influence component values of an influencing factor is randomly selected from the data set as the selection object, and at the same time, the influence component values in the same dimension of the other two influencing factors are selected as heterogeneous objects, and the selection is repeated until the number of iterative selections of the object is reached; the distance between the selection object and the heterogeneous object in the characteristic information is analyzed, and the key factors affecting the energy consumption change are determined in combination with the Shapley additive explanation technology, and a numerical set of the key factors is generated; the energy consumption of the electrical device under the numerical set is calculated, and the total power carbon emission is judged according to the functional relationship between the energy consumption of the electrical device and the carbon emission amount.

[0080] Among them, the calculation formula for the total influence component value is: ;

[0081] In the formula, β represents the total influence component value, β F represents the influence component value under the load fluctuation mode, β Y represents the influence component value under the operating cycle mode, β H represents the influence component value under the environmental impact mode, a represents the accumulation order, c b represents the regression coefficient of the influence component under the load fluctuation mode, D b represents the b th load fluctuation value under the f 1e and f 2e represent the regression coefficient of the influence component under the operating cycle mode, t represents the cumulative number of days from the start observation date to the end observation date of the current operating strategy, e represents a constant, i h represents the regression coefficient of the influence component under the environmental impact mode, J h represents the h th aging factor.

[0082] It should be noted that in the process of obtaining the key factors affecting energy consumption changes, the influencing factors are first selected, including the load fluctuation pattern, the environmental impact pattern, and the operating cycle pattern;

[0083] Specific implementation:

[0084] Load fluctuation pattern: The load fluctuation pattern represents the change of the device load. For example, the load fluctuation of the device in different time periods. This pattern can be constructed based on historical power consumption data and the change of the device load. By methods such as time series analysis or FFT (Fast Fourier Transform), the frequency characteristics of the device load are extracted to obtain the load fluctuation pattern.

[0085] Environmental impact pattern: The environmental impact pattern considers the impact of external environmental factors such as temperature, humidity, and air pressure on the device operation efficiency and energy consumption. For example, an increase in temperature may lead to an increase in the energy consumption of the device.

[0086] Operating cycle pattern: The operating cycle pattern refers to the operating law of the device within a certain cycle. For example, the energy consumption of some devices is relatively high at startup and relatively low during periodic operation. Considering the start-stop frequency and continuous working duration of the device, this pattern can help analyze the energy consumption fluctuation of the device in different working states. According to the start-stop records of the device, the operating cycle pattern can be extracted. Different cycles can be divided by clustering algorithms (such as K-means), and the energy consumption changes of the device under different cycles can be analyzed.

[0087] For each influencing factor (load fluctuation, environmental impact, and operating cycle), the Shapley Additive Explanations (SHAP) technique is used to evaluate the contribution of this factor to the device energy consumption. The SHAP method is derived from cooperative game theory and is used to measure the marginal contribution of features to the model output.

[0088] Shapley value: For each influencing factor, the SHAP method calculates the contribution of this factor in different subsets to obtain a "contribution score" or influence value. This influence value represents the relative influence of this factor on the total energy consumption change of the device. The calculation method of SHAP:

[0089] Feature selection: First, specific features of each influencing factor (load fluctuation, environmental impact, operating cycle) are selected. For example, load fluctuation can include load fluctuation frequency and amplitude; environmental impact can include temperature and humidity; operating cycle can include startup time and duration, etc.

[0090] Calculating the Shapley value: For each feature, calculate its influence value among all possible feature combinations. This means combining this feature with other features and calculating the marginal contribution of this feature by comparing the impact on the model output (energy consumption) with and without this feature.

[0091] Therefore, for each influencing factor, a corresponding influence component value can be obtained finally, which reflects its influence degree on energy consumption. Then, take the Shapley value of each influencing factor as the influence component value, and sum up the influence component values of all influencing factors to get the "total influence component value". This value represents the change in equipment energy consumption under the combined action of various influencing factors.

[0092] During the initialization of the feature set and the data set, the feature set contains the feature data of all influencing factors (such as load fluctuation patterns, environmental impact patterns, operation cycle patterns). These feature data constitute the input for subsequent model training; take the total influence component value as the target value (label) of the data set for training the model. The data set will be used in the subsequent iterative process for optimizing the modeling of the influencing factors and energy consumption changes. Set the initial number of iterations and the number of selected nearest neighbors for subsequent feature selection and optimization algorithms (such as KNN, support vector machines, etc.). The number of iterations determines the training accuracy of the model, and the number of nearest neighbors is used to adjust the distance metric during training, thereby affecting the performance of the model.

[0093] Randomly select a set of influence component values of influencing factors from the data set as the selection object, that is, select a sample of a specific influencing factor. For the other two influencing factors, randomly select their influence component values as heterogeneous objects in the same dimension (such as the same time, environment, or cycle state). It can be understood as combining different behavior patterns (load, environment, cycle) together for comparative analysis. Through iteration, continuously randomly select a set of "selection objects" and two sets of "heterogeneous objects" from the data set. In each iteration, the influencing factor and its corresponding influence component value will be used as the data points for training the model. This iterative process can help generate more feature combinations and enhance the generalization ability of the model to ensure that the model can adapt to various different operation strategies and different electricity consumption environments.

[0094] Through iterative selection, a data set containing multiple selection objects and heterogeneous objects is finally obtained. Each data point represents a specific equipment operation mode. These data points will be used to train a machine learning model to help predict energy consumption changes and carbon emissions.

[0095] In one embodiment, in the process of analyzing the distance between the selected object and the heterogeneous object in terms of feature information, and combining the Shapley additive explanation technique to determine the key factors affecting the energy consumption change and generate a numerical set of the key factors, the importance value of the selected object can be analyzed based on the distance result, and the importance value of the object can be repeatedly analyzed according to the number of iterative selections, and the maximum importance value is used as the corresponding feature weight; analyze the Shapley values of each influencing factor, take the average of the absolute values of the Shapley values to obtain the feature contribution value of each influencing factor, and collectively refer to the feature contribution value and the feature weight as the factor contribution value; analyze the cumulative contribution rate of each influencing factor contribution value in the total factor contribution value, calculate the cumulative contribution rate difference of each influencing factor according to the cumulative contribution rate, and compare the cumulative contribution rate difference with the cumulative contribution rate difference threshold; select the influencing factors with the cumulative contribution rate difference greater than the cumulative contribution rate difference threshold as the key factors affecting the energy consumption change, and generate a numerical set of the electrical equipment under different operation strategies according to the key factors.

[0096] In one embodiment, in the process of analyzing the duration corresponding to the complete discharge of the total electricity carbon emissions by using the carbon emission factor and evaluating the emission efficiency of the power supply equipment in the smart park according to the duration result, the total electricity carbon emissions can be respectively regarded as the total carbon emissions of direct electricity consumption and the total carbon emissions of purchased electricity, and the carbon emission rate can be set according to the corresponding carbon emission factor to obtain the emission duration of the direct electricity consumption equipment and the emission duration of the purchased electricity equipment; obtain the decision factors affecting the carbon emissions of the direct electricity consumption equipment and the purchased electricity equipment, establish a direct influence relationship matrix, and perform a normalization process on the direct influence relationship matrix to obtain a normalized influence matrix; obtain the comprehensive influence matrix of the normalized influence matrix, add the factors in each row of the comprehensive influence matrix to obtain the influence degree, and at the same time add the factors in each column of the comprehensive influence matrix to obtain the influenced degree; calculate the centrality and reason degree of each factor based on the influence degree and the influenced degree, determine the emission duration evaluation index system according to the calculation result, and respectively evaluate the relative efficiency of the carbon emissions of the direct electricity consumption equipment and the purchased electricity equipment in combination with the data envelopment analysis model.

[0097] It should be noted that in the process of relative efficiency evaluation, the total electricity carbon emissions of the smart park can be split into two parts:

[0098] Total carbon emissions of direct electricity consumption: The carbon emissions generated by the electricity directly provided by the self-owned power generation equipment in the park (such as wind energy, solar energy, coal-fired generators, etc.); Total carbon emissions of purchased electricity: The carbon emissions generated by the electricity purchased through the external power grid.

[0099] For each power source (direct power consumption and purchased electricity), different carbon emission factors need to be set. These factors represent the carbon emissions generated per unit of power consumption. Generally, the carbon emission factor of purchased electricity depends on the overall energy composition of the power grid (such as the proportion of thermal power generation, etc.), while the carbon emission factor of direct power consumption may be set based on factors such as equipment type and operating efficiency.

[0100] The carbon emission rate can be calculated by the following formula: Carbon emission rate = time / total carbon emissions. Based on the total carbon emissions of direct power consumption and purchased electricity and the set carbon emission factors, the carbon emission rates of these two parts of power supply can be calculated.

[0101] Identification of decision factors: Decision factors for carbon emissions of direct power consumption equipment: For example, power demand of the equipment, load fluctuation, operating time, equipment energy efficiency, etc.; Decision factors for carbon emissions of purchased electricity equipment: For example, power source of the power grid (whether mainly coal-fired power), external electricity price, external power grid load, etc.

[0102] The influence relationship matrix describes the mutual influence relationships among decision factors. The elements in the matrix represent the direct influence degree between decision factors. The larger the value, the stronger the influence between two factors. For example, if the energy efficiency of the equipment has a greater impact on the carbon emissions of direct power consumption equipment, a larger weight will be assigned to the corresponding position in the matrix. The purpose of normalization is to standardize all values in the influence relationship matrix to the same dimension (such as values between 0 and 1) to better compare the influence intensities of different factors; The comprehensive influence matrix can be obtained by matrix weighted summation of the normalized influence matrix, reflecting the mutual influence degree among all factors: The influence degree of each row factor (decision factor) on other factors is obtained by summing each row; The influenced degree of each column factor (decision factor) by other factors is obtained by summing each column.

[0103] Centrality is an index to measure the importance of a factor in the influence network. The greater the influence degree, the stronger the influence of this factor, so it can be considered that this factor is "central"; Causality is a measure of the degree to which a factor affects other factors as a "cause", measured based on the "influenced degree" of this factor, that is, the degree to which this factor affects other factors.

[0104] Based on the calculation results of the influence degree and the influenced degree, an evaluation index system for emission duration is established. This system can include factors such as influence degree, causality, carbon emission rate, etc., comprehensively reflecting the carbon emission efficiency of the equipment. Data Envelopment Analysis (DEA) is a technology based on efficiency evaluation, which evaluates the relative efficiency by comparing the inputs and outputs of different equipment.

[0105] In this embodiment, the DEA model can be used to evaluate the carbon emission efficiency of direct electricity-consuming equipment and externally purchased electricity equipment. Through the DEA model, the relative efficiency between different equipment (input carbon emissions and output electricity) is compared to identify the most efficient equipment operation strategy.

[0106] DEA model calculation:

[0107] Inputs: total carbon emissions, total energy consumption, etc.; Outputs: electricity supply, system efficiency, etc.

[0108] DEA will calculate the relative efficiency value of each equipment based on these input-output data, providing a reference for the best practices of equipment carbon emissions and energy consumption.

[0109] To facilitate the understanding of the above technical solution of the present invention, the following will provide a detailed description of the evaluation method of the emission efficiency of the present invention in the actual process.

[0110] Step 1: Mean clustering and energy consumption condition analysis;

[0111] (1) Data collection and preprocessing:

[0112] Collect the historical total carbon emissions and energy consumption data of the intelligent park's electricity-consuming equipment. The following are some example data:

[0113] Total carbon emissions: Calculated through the electricity carbon emission factor, with the unit of ton CO2.

[0114] Assume that the electricity carbon emission factor of the intelligent park is 0.4 ton CO2 / 1000 kWh (kWh). If the intelligent park consumes 100,000 kWh of electricity in a month, the total carbon emissions are: Total carbon emissions = 100,000 kWh × 0.4 (ton CO2 / kWh) = 40 tons CO2;

[0115] Electricity-consuming equipment energy consumption data:

[0116] Assume that there are the following types of equipment in the park:

[0117] Air conditioning system: The energy consumption in January is 10,000 kWh, and in February is 12,000 kWh;

[0118] Lighting system: 5,000 kWh in January and 4,800 kWh in February;

[0119] Elevator system: 3,500 kWh in January and 3,700 kWh in February;

[0120] Computer equipment: 6,000 kWh in January and 6,100 kWh in February;

[0121] Clean the energy consumption data collected from electrical equipment to handle issues such as missing values, outliers, and inconsistent data formats. For example, if the energy consumption data of certain equipment is missing in a specific month, it needs to be filled (methods such as mean filling and previous value filling can be used). Outliers (such as extreme peak values) can be judged based on the equipment operation situation whether it is a data entry error or an abnormal fluctuation, and adjusted accordingly.

[0122] To simplify the electrical energy consumption data and remove redundant information, principal component analysis (PCA) is used to reduce the dimensionality of the data. Assume that the electrical data has the following characteristics:

[0123] Load fluctuation frequency: The number of fluctuations of the equipment load per unit time;

[0124] Energy consumption: The monthly electricity consumption of the equipment (unit: kWh);

[0125] Environmental factors: For example, the impact of temperature and humidity on energy consumption;

[0126] Through PCA, eigenvalue decomposition is performed on the covariance matrix to obtain the main dimension vectors. Select the first few principal components, and these components retain most of the variance in the data. Assume that two main components (main dimension vectors) are obtained for subsequent analysis. Perform mean clustering analysis on each main dimension vector to find similar energy consumption patterns. Assume that K =3 clusters are selected for clustering analysis, and the K-means algorithm is used.

[0127] The clustering process is for each main dimension vector. Randomly select the initial center points, use the Euclidean distance metric to assign the data points to the closest center points, and recalculate the center points of the clusters until the clustering results converge. Through clustering analysis, three typical energy consumption working conditions are identified:

[0128] Low energy consumption mode: The equipment operates at a low load state with low energy consumption; Medium energy consumption mode: The equipment operates at a standard load state with moderate energy consumption; High energy consumption mode: The equipment operates at a high load state with high energy consumption; Combine each energy consumption mode and the corresponding carbon emissions to analyze the impact of the energy consumption working conditions on carbon emissions.

[0129] Step 2: Analysis of key factors affecting energy consumption changes;

[0130] According to the PCA dimensionality reduction results and clustering analysis, calculate the Pearson correlation coefficient between each main dimension vector and carbon emissions. Assume that the correlation coefficients obtained through calculation are:

[0131] Correlation coefficient between main dimension 1 and carbon emissions: 0.85; Correlation coefficient between main dimension 2 and carbon emissions: 0.75; According to the Pearson correlation coefficient, construct a relationship model between carbon emissions and energy consumption. Assume that an LSTM model is used for modeling: Carbon emissions = τ1 × Main Dimension 1 + τ 2 × Main Dimension 2 + ν , where τ 1 and τ 2 are regression coefficients, ν is the intercept term. By solving the regression coefficients using the least squares method, the functional relationship between carbon emissions and energy consumption is obtained.

[0132] Through the feature selection algorithm and the Shapley Additive Explanation technique (SHAP), analyze the contributions of the load fluctuation pattern, environmental impact pattern, and operation cycle pattern to the change in equipment energy consumption. Assuming different operation strategies, the following impact component values are obtained through SHAP calculation:

[0133] Impact component value of the load fluctuation pattern: 0.60; Impact component value of the environmental impact pattern: 0.25; Impact component value of the operation cycle pattern: 0.15; reflecting the relative contributions of each impact factor to the change in equipment energy consumption.

[0134] Step 3. Emission efficiency assessment;

[0135] Based on the constructed carbon emission model and the analysis results of the impact factors, the total electricity carbon emissions of the smart park under any operation strategy can be predicted. For example, assuming that the operation strategy of the equipment leads to the following changes in energy consumption:

[0136] Change in Main Dimension 1: Increase by 200 kWh; Change in Main Dimension 2: Decrease by 100 kWh;

[0137] According to the model, predict the carbon emissions: Predicted carbon emissions = τ 1 × 200 + τ 2 × (-100) + ν ; Based on the carbon emission rate calculated from the carbon emission factor, evaluate the emission efficiency of the power supply equipment. According to the set carbon emission factor (0.4 tons of CO2 / kWh), we get:

[0138] Direct electricity carbon emission rate: 0.4 tons of CO2 / kWh;

[0139] Carbon emission rate of purchased electricity: Assume the carbon emission factor of purchased electricity is 0.5 tons of CO2 / kWh.

[0140] Through the Data Envelopment Analysis (DEA) model, evaluate the carbon emissions and energy consumption of each equipment, and calculate the relative efficiency value of each equipment. For example: Emission efficiency of direct electricity equipment: 0.8 (higher efficiency); Emission efficiency of purchased electricity equipment: 0.6 (lower efficiency).

[0141] Therefore, based on the above steps, a relationship model between the total carbon emissions and the energy consumption of electrical equipment can be accurately constructed to predict the total carbon emissions of electrical equipment in the smart park under different operation strategies, and to judge the emission efficiency corresponding to the total carbon emissions of electricity. Finally, based on these analysis results, the park managers can optimize the equipment operation strategies, reduce carbon emissions, and improve energy efficiency.

[0142] Step S3: Generate an electricity usage allocation model based on the total carbon emissions of electricity and the emission efficiency, determine the electricity carbon emission reduction strategy in the smart park, and evaluate the energy conservation and emission reduction effect of the smart park after the application of the electricity carbon emission reduction strategy according to the total carbon emissions of electricity.

[0143] In one embodiment, in the process of generating an electricity usage allocation model based on the total carbon emissions of electricity and the emission efficiency, determining the electricity carbon emission reduction strategy in the smart park, and evaluating the energy conservation and emission reduction effect of the smart park after the application of the electricity carbon emission reduction strategy, the electricity consumption details, time granularity data, and historical electricity consumption data in the smart park can be obtained, and the time series model can be combined to identify the trend prediction and seasonal changes of electricity consumption to determine the peak and off-peak periods of electricity consumption; analyze the total electricity cost and regional electricity cost in the smart park according to the electricity price data, and analyze the equipment usage situation during the peak electricity consumption period in combination with the electricity consumption details to obtain the electricity demand in the smart area; construct a multi-objective integrated planning model with the minimum power generation cost as the objective function, and generate the optimal output combination corresponding to the dynamic allocation of direct electricity and purchased electricity in combination with the total carbon emissions of electricity and the emission efficiency; obtain the direct electricity consumption and purchased electricity consumption in the smart park according to the optimal output combination, determine the electricity carbon emission reduction strategy in the smart park, and obtain the total carbon emissions of electricity in the smart park after the application of the optimal output combination; compare the difference between the total carbon emissions of electricity obtained after the application of the optimal output combination and the initial total carbon emissions of electricity to evaluate the energy conservation and emission reduction effect of the smart park after the application of the electricity carbon emission reduction strategy.

[0144] In one embodiment, in the process of constructing a multi-objective integrated planning model with the minimum power generation cost as the objective function and generating the optimal output combination corresponding to the dynamic allocation of direct power consumption and purchased power by combining the total power carbon emissions and emission efficiency, the total power generation cost under the condition of meeting the power consumption demand can be calculated based on the power consumption demand and power consumption cost of the smart park, and the power generation cost value required for direct power consumption or purchased power to meet the power consumption demand at any time period within the smart park can be analyzed according to the total power generation cost; taking the minimum power generation cost value and the minimization of carbon emissions as the objective function and the capacity of the power generation equipment as the constraint condition, combining the single objective function and the constraint condition to construct a multi-objective integrated planning model; assigning weights to the objective function by the weighted sum method, and finding a trade-off based on Pareto optimality to obtain the output balance point of the multi-objective integrated planning model, and determining the combined allocation optimization result of the multi-objective integrated planning; taking the total power carbon emissions and emission efficiency as the basis for judging the fairness of the output combination, verifying the fairness of the combined allocation optimization result by using the calculation formula of the fairness of the output combination allocation, and outputting the optimal output combination corresponding to the dynamic allocation of direct power consumption and purchased power according to the fairness result.

[0145] It should be noted that in the process of outputting the optimal output combination, the goal is to minimize the total power generation cost of the smart park under the condition of meeting the power consumption demand. Here, the power generation cost involves two parts: direct power consumption and purchased power.

[0146] Direct power consumption cost: The cost of power supply generated by the power generation equipment in the smart park;

[0147] Purchased power consumption cost: The cost of power purchased from the external power grid;

[0148] Minimization of carbon emissions: The goal is to reduce the total carbon emissions, and the emissions are reduced by optimizing the power consumption method, such as by selecting power generation equipment or purchased power with a lower carbon emission factor.

[0149] The power consumption demand constraint is to ensure that at any time period, the sum of direct power consumption and purchased power can meet the power consumption demand of the park, that is: D ( t ) = P direct ( t ) + P purchase ( t ), where P direct ( t ) represents the direct power consumption at time t , P purchase ( t ) represents the purchased power consumption, D ( t ) represents time tThe electricity demand at a moment.

[0150] Power generation equipment capacity constraint: Each power generation equipment has a maximum power generation capacity, which cannot exceed its designed capacity: P direct ( t ) ≤ P max,direct , where P max,direct represents the maximum power generation capacity of the direct power consumption source.

[0151] Construct a multi-objective optimization model that includes two objective functions (minimizing power generation cost and minimizing carbon emissions). To make the model operable in practice, the weighted sum method is used to transform the two objective functions into a single objective function: Objective function = U 1 × power generation cost + U 2 × total carbon emissions objective function; U 1 and U 2 are the weight coefficients of the objective function, which reflect the relative importance between power generation cost and carbon emissions. The weights can be determined through expert evaluation or sensitivity analysis, and the power generation cost and total carbon emissions can be calculated based on the equipment and power carbon emission factors in the smart park.

[0152] For each time period, the cost of direct power consumption and the cost of purchased electricity are calculated based on factors such as the fuel cost of the power generation equipment, the electricity market price, and the equipment efficiency of direct power consumption. The carbon emissions of each power generation equipment can be calculated by multiplying the electricity consumed by the equipment by the carbon emission factor of the equipment. Carbon emissions = ∑ l P l ( t ) × carbon emission factor l where P l ( t ) is the power generation of equipment l at time t , and the carbon emission factor l is the carbon emission factor of the equipment.

[0153] In multi-objective optimization, the objective functions are conflicting with each other. Therefore, it is necessary to find a balance point to achieve a compromise effect. To obtain the optimal solution, the concept of Pareto optimality can be used, that is, under the given constraints, find a solution that is not dominated by any other solution.

[0154] Dominance relationship: For two solutions E and G , if E is not inferior to G in all objectives and is superior to G in at least one objective, thenE dominance G In multi-objective optimization, the Pareto optimal solution means that there is no solution that can be better than this solution in all objectives. To find the Pareto optimal solution, some common optimization algorithms can be used. For example: Genetic algorithm: By simulating the biological evolution process, operations such as crossover and mutation are used to find the optimal solution; Particle Swarm Optimization (PSO): Simulates the collective behavior of bird flocks or fish schools to find the optimal solution.

[0155] In the weighted sum method, the relative importance between objectives is set by giving weights U 1 and U 2. For example: If U 1 is larger, it means that the power generation cost takes precedence over carbon emissions; if U 2 is larger, it means that reducing carbon emissions takes precedence over the power generation cost. The weights can be adjusted according to different operation strategies, policy requirements or expert opinions, and sensitivity analysis can be used to evaluate the changes in the model results under different weights.

[0156] The fairness of the allocation of direct power consumption and purchased power is judged by the total carbon emissions and emission efficiency. The core idea of fairness evaluation is: while meeting the power consumption demand, try to make the carbon emission efficiency of the two power consumption methods close to avoid over-reliance on one method, resulting in excessive carbon emissions.

[0157] Through the above process, the optimal output combination of direct power consumption and purchased power is finally output, that is, how to reasonably allocate the power demand of the park within a certain period of time, which not only meets the power consumption demand but also minimizes the power generation cost and carbon emissions. The allocation of direct power consumption and purchased power will be dynamically adjusted to adapt to actual demand fluctuations, energy cost changes and carbon emission requirements. The output results can provide optimization suggestions for park managers to select the optimal power supply method at different time periods.

[0158] Among them, the calculation formula for the fairness of output combination allocation is: ;

[0159] In the formula, max Z represents the fairness of output combination allocation, α represents the power consumption demand of electrical equipment in the smart park, A represents the set of power consumption demands of electrical equipment in the smart park, δ represents the time point, B represents the set of time points, ε represents the relative efficiency of carbon emissions, N represents the set of carbon emission efficiencies, σ represents the transmission point in the power supply process in the smart park, Q represents the set of transmission points in the power supply process in the smart park,ρ Represents the transmission path during the power supply process in the smart park, P Represents the set of transmission paths during the power supply process in the smart park, S σ,α,δ,ρ Represents the δ th time period, the σ th transmission point, and the ρ th transmission path to meet the α th power consumption demand of the electrical equipment, the required power generation cost value, R α,δ Represents the δ th time period to meet the α th power consumption demand of the electrical equipment, the required capacity of the power generation equipment, λ α,δ During the δ th time period to meet the α th power consumption demand of the electrical equipment, the required power transmission duration.

[0160] It should be noted that during the operation of the power carbon emission reduction strategy, according to the carbon emission quota set by the park, different warning levels are defined (such as yellow warning, orange warning, red warning), and each level corresponds to a different degree of over-standard risk. Considering factors such as seasonal fluctuations and special activities, the warning threshold is adjusted in a timely manner to better adapt to the actual situation.

[0161] Classification suggestions:

[0162] Low-level warning (yellow): Inform users that the current carbon emissions are approaching the quota ceiling, encourage them to take some simple energy-saving measures, such as turning off unnecessary electrical equipment, and provide tips or links on energy conservation and emission reduction to help users understand how to effectively reduce personal or departmental carbon emissions.

[0163] Medium-level warning (orange): For specific areas or facilities, give a detailed energy-saving plan, such as adjusting the air-conditioning temperature setting, optimizing the lighting schedule, etc., and perform temporary power limit or operation mode switching on key energy-consuming equipment to avoid a sharp increase in carbon emissions in the short term.

[0164] High-level warning (red): Activate the emergency plan, such as mobilizing the emergency team to check and repair problem points that may cause high carbon emissions; when necessary, turn off non-essential production equipment or services, evaluate the deficiencies of the existing energy management system, and formulate medium- and long-term improvement measures, such as introducing more renewable energy and upgrading energy storage facilities.

[0165] To facilitate the understanding of the above technical solutions of the present invention, the following will detail the determination method of the power carbon emission reduction strategy in the smart park during the actual process of the present invention.

[0166] Step 1: Data preparation;

[0167] Before implementing the power carbon emission reduction strategy, it is necessary to collect and analyze various data of the smart park. The following are some examples of key data:

[0168] Electricity consumption details data: Total electricity consumption of the system (unit: kWh): For example, the total electricity consumption of the park on a certain day is 10,000 kWh;

[0169] Regional electricity consumption: For example, the park is divided into three regions A, B, and C. The electricity consumption of region A is 4,000 kWh, that of region B is 3,000 kWh, and that of region C is 3,000 kWh.

[0170] Sub-system electricity consumption: For example, the electricity consumption of the air conditioning system is 2,000 kWh, and that of the lighting system is 1,500 kWh.

[0171] Electricity price data: Daily electricity price (unit: yuan / kWh). For example, the electricity price during peak hours is 1.0 yuan / kWh, and that during off-peak hours is 0.5 yuan / kWh;

[0172] Carbon emission data: Carbon emission factor (unit: ton CO2 / kWh). The carbon emission factor of direct electricity-consuming equipment is 0.4 ton CO2 / kWh, and that of purchased electricity is 0.5 ton CO2 / kWh.

[0173] Total carbon emissions: Assume that the total carbon emissions of the smart park are 4 tons CO2.

[0174] Historical electricity consumption data:

[0175] High electricity consumption areas: For example, region A is often a high electricity consumption area in summer;

[0176] Low electricity consumption areas: Region C is often a low electricity consumption area in summer;

[0177] Energy-saving measure evaluation data:

[0178] Energy-saving measures: Adjusting air conditioning temperature, using high-efficiency lighting, etc., with an energy-saving effect of 10%.

[0179] Step Two: Power usage allocation model;

[0180] It is necessary to optimize the power usage allocation within the smart park according to factors such as electricity demand, carbon emission factor, and electricity price data. The goal is to reduce the total power generation cost and carbon emissions by reducing peak-hour power consumption and optimizing the power source.

[0181] (1) Determine the electricity demand: Assume that the total electricity consumption of 10,000 kWh needs to be met within a specific time period (such as 24 hours a day), and the electricity demand of each region is known as follows:

[0182] Region A: 4000 kWh; Region B: 3000 kWh; Region C: 3000 kWh;

[0183] (2)Analyze electricity prices and carbon emissions:

[0184] Electricity prices have a greater impact on the cost of electricity consumption, especially during peak periods:

[0185] The electricity price during peak hours is 1.0 yuan / kWh;

[0186] The electricity price during off-peak hours is 0.5 yuan / kWh;

[0187] At the same time, different power sources (direct electricity consumption and purchased electricity) also have different carbon emission factors:

[0188] Direct electricity consumption: 0.4 tons of CO2 / kWh; Purchased electricity: 0.5 tons of CO2 / kWh.

[0189] Step 3: Analysis of electricity consumption costs;

[0190] Based on the electricity price data, the electricity consumption costs of different regions can be analyzed. For example:

[0191] The electricity consumption cost of Region A is 4000 kWh × 1.0 yuan / kWh = 4000 yuan (assuming all are peak hours);

[0192] The electricity consumption cost of Region B is 3000 kWh × 0.5 yuan / kWh = 1500 yuan (assuming all are off-peak hours);

[0193] The electricity consumption cost of Region C is 3000 kWh × 1.0 yuan / kWh = 3000 yuan (assuming all are peak hours).

[0194] Step 4: Optimize the allocation of electricity use based on carbon emissions;

[0195] It is necessary to reduce the total carbon emissions of the park through optimization strategies. The following is a possible strategy:

[0196] During peak electricity periods (1.0 yuan / kWh), try to use purchased electricity (emission factor is 0.5 tons of CO2 / kWh); during off-peak electricity periods (0.5 yuan / kWh), give priority to using direct electricity (emission factor is 0.4 tons of CO2 / kWh), and reduce the electricity demand during peak periods through system scheduling.

[0197] Assume that during off-peak hours, it is decided that Region A uses 2000 kWh of direct electricity and Region B uses 3000 kWh of purchased electricity; during peak hours, Region A uses 2000 kWh of purchased electricity, Region B uses 0 kWh of purchased electricity, and Region C uses 3000 kWh of purchased electricity.

[0198] The goal is to minimize the power generation cost and carbon emissions. A single objective function is constructed by the weighted sum method to balance these two goals: Objective function = U 1 × power generation cost + U 2 × total carbon emissions where: U 1 = 0.6 (reflecting a cost - priority strategy); U 2 = 0.4 reflecting the priority of carbon emissions reduction.

[0199] In multi - objective optimization, genetic algorithms or particle swarm optimization are used to solve the Pareto optimal solution, that is, to find a compromise point between power generation cost and carbon emissions.

[0200] Dominance relationship: Suppose two solutions E and G are obtained. If solution E is superior to solution G in terms of cost, and is also superior to solution G in terms of carbon emissions, then solution E will dominate solution G , and then gradually adjust the power source and the output of power generation equipment until a solution that meets the power demand and maximally reduces costs and carbon emissions is found.

[0201] Step Four: Apply the optimal output combination;

[0202] The results of the optimal output combination may be as follows:

[0203] Region A: Direct power consumption 2000 kWh, purchased power 2000 kWh;

[0204] Region B: Direct power consumption 0 kWh, purchased power 3000 kWh;

[0205] Region C: Direct power consumption 0 kWh, purchased power 3000 kWh;

[0206] Suppose these output combinations are optimal in terms of balancing cost and carbon emissions.

[0207] According to the comparison between the optimal output combination and the initial total power carbon emissions, evaluate the energy - saving and emission - reduction effect:

[0208] Initial total carbon emissions: 10000 kWh × 0.4 tons CO2 / kWh = 4 tons CO2;

[0209] Total carbon emissions under the optimal output combination: Suppose the total carbon emissions under the optimal output combination are 3.5 tons CO2;

[0210] The energy - saving and emission - reduction effect is: Emission reduction = 4 tons CO2 - 3.5 tons CO2 = 0.5 tons CO2, which means that through the application of the optimal power usage allocation model, the carbon emissions of the smart park have been reduced by 0.5 tons CO2.

[0211] Based on the evaluation data of energy-saving measures, the effects of energy-saving measures (such as adjusting air-conditioning temperature, optimizing lighting, etc.) in different time periods can be further analyzed and compared with the same period in the past.

[0212] For example: In a certain energy-saving cycle, the park saved 10% of the power consumption by adjusting the air-conditioning temperature, reducing 0.2 tons of CO2 emissions. The final result is that through optimizing power distribution and implementing energy-saving measures, the smart park achieved the goal of reducing 0.7 tons of CO2 emissions.

[0213] Therefore, through the above process, a power usage allocation model based on the total power carbon emissions and emission efficiency is constructed, and the power carbon emission reduction strategy for the smart park is determined. With the support of real-time data monitoring and optimization algorithms, it can provide the best power usage strategy for the park, not only effectively reducing carbon emissions, but also achieving energy conservation and emission reduction, and providing strong support for sustainable development.

[0214] In the second aspect, the present invention also provides a smart park power carbon emission prediction system based on artificial intelligence, which includes:

[0215] A total carbon emission calculation unit 1, which is used to obtain the data of the external purchased power activities and direct power consumption data in the smart park, and calculate the carbon emissions of the external purchased power and the direct power consumption in the smart park by using the power carbon emission accounting standard to obtain the total carbon emissions;

[0216] A carbon emission efficiency judgment unit 2, which is used to construct a relationship model between the total carbon emissions and the energy consumption of the electrical equipment, predict the total power carbon emissions generated by the electrical equipment in the smart park under any operation strategy, and judge the emission efficiency corresponding to the total power carbon emissions;

[0217] An energy-saving strategy execution evaluation unit 3, which is used to generate a power usage allocation model based on the total power carbon emissions and emission efficiency, determine the power carbon emission reduction strategy in the smart park, and evaluate the energy conservation and emission reduction effect of the smart park after using the power carbon emission reduction strategy according to the total power carbon emissions.

[0218] In summary, by means of the above technical solutions of the present invention, the present invention can accurately calculate the total carbon emissions by obtaining the data of the external purchased power activities and direct power consumption data in the smart park, provide reliable data support for subsequent analysis, and construct a relationship model between the total carbon emissions and the energy consumption of the electrical equipment, which can provide scientific predictions for the power carbon emissions under different operation strategies.
