Description

Technical Field

[0001] The present invention relates to the technical field of carbon emission management, and in particular to a method for evaluating carbon neutrality in a park. Background Art

[0002] Against the backdrop of increasingly serious global climate change issues, carbon neutrality refers to enterprises offsetting their own carbon dioxide or greenhouse gas emissions through energy conservation and emission reduction, achieving positive and negative offsets, achieving relative "zero emissions", and alleviating the trend of global warming. Excessive carbon emissions can lead to an imbalance in the ecosystem and affect biodiversity and ecological service functions. By reducing carbon emissions, the concentration of greenhouse gases in the atmosphere can be reduced, thereby slowing the trend of climate warming and helping to protect the integrity and stability of the ecosystem. By promoting clean energy, energy conservation and emission reduction measures, the coordinated development of the economy, society and the environment can be promoted. Optimize the energy structure, increase the proportion of non-fossil energy, and reduce dependence on fossil fuels. Strengthen energy conservation management in industries, construction, transportation and other fields, and promote high-efficiency energy-saving technologies and equipment. At the same time, carbon capture and storage technology is used to capture and store carbon dioxide emitted by industry to prevent it from entering the atmosphere. Park carbon neutrality is a systematic and complex process that requires comprehensive consideration of multiple factors. Through scientific and reasonable evaluation methods, the park can be effectively guided to achieve carbon neutrality goals and promote sustainable development.

[0003] At present, the evaluation methods for carbon neutrality in traditional industrial parks lack comprehensiveness. They mainly focus on technical measures such as energy management, energy conservation and emission reduction, but ignore the energy-saving transformation of the industrial production chain. In addition, traditional evaluation methods lack dynamic evaluation capabilities and cannot reflect the changing trends of carbon emissions in the industrial park in different time periods. The accuracy and effectiveness of the evaluation results need to be improved. Summary of the invention

[0004] In response to the above problems, the present invention provides an evaluation method for carbon neutrality of a park, aiming to solve the problem that the traditional park carbon neutrality evaluation method ignores the energy-saving transformation of the industrial production chain and cannot reflect the changing trend of carbon emissions in the park in different time periods.

[0005] The specific technical solution provided by the present invention is: a method for evaluating carbon neutrality in a park, comprising the following steps:

[0006] Step 1: Connect to the park management platform through the network to obtain the park's daily production and operation data and energy consumption data, and classify the acquired data into operation data sets and consumption data sets;

[0007] Step 2: Obtain the hourly carbon emissions and carbon capture of the park through network-connected sensor devices, and form an emission data set with the acquired data;

[0008] Step 3: Based on the operation data set and the consumption data set, analyze the proportional relationship between the park's production operation data and energy consumption data under different production operation modes, and generate the corresponding productivity Scl;

[0009] Step 4: Based on the emission data set, analyze the balance trend of the park's carbon emissions and carbon capture in a single day, generate the corresponding net zero index Jlzs, and then analyze the park's hourly net carbon emissions to generate the net carbon data group Jtsj;

[0010] Step 5: Set a fixed range of energy consumption thresholds, a fixed value of the restricted number of days XT, and a fixed value of the standard productivity Bcl, and combine the consumption data set and productivity Scl to determine the risk level of carbon neutrality imbalance in the park, and evaluate whether there is an imbalance in the energy configuration of each link in the park's production chain;

[0011] Step 6: Set the fixed range index threshold ZY and net carbon threshold JTY, and combine the net zero index Jlzs and net carbon data group Jtsj to evaluate the carbon neutrality effect of the park and output the judgment results.

[0012] Furthermore, in step 1, the expression of the operation data set is to They correspond to the daily production and operation data of the park, which include raw material collection volume, processing output and storage volume. d represents the time point corresponding to the single-day production and operation data, m represents the single-day production and operation mode, and 1 to x represent that there are x groups of production and operation data obtained.

[0013] Furthermore, in step 1, the expression of the consumption data set is {N1 s 、N2 s 、N3 s , ..., Nx s},N1 s To Nx s These correspond to the daily energy consumption data of the park, which include water consumption, electricity consumption and fuel consumption. s represents the time point corresponding to the daily energy consumption data, and 1 to x represents that there are x groups of energy consumption data obtained.

[0014] Furthermore, in step 2, the expression of the emission data set is to They correspond to the hourly carbon emissions and carbon capture of the park respectively, p represents the hourly carbon emissions of the park, b represents the hourly carbon capture of the park, and 1 to h represent that there are h groups of carbon emissions and carbon capture obtained.

[0015] Further, in step 3, the calculation steps of the productivity Scl are as follows:

[0016] Extract the production and operation data of the park on the kth day under the i-th production and operation mode in the operation data set and mark it as represents the amount of raw materials collected in the park on the kth day, represents the processing output of the park on the kth day, represents the storage volume of the park on the kth day, and d represents the time point corresponding to the single-day production and operation data;

[0017] According to the production and operation data of the park on the kth day, the energy consumption data of the park on the kth day in the consumption data set is extracted and marked as represents the water consumption of the park on the kth day, Including water consumption in the collection of raw materials Water consumption in processing and water consumption in storage represents the electricity consumption of the park on the kth day, Including electricity consumption in the raw material collection process Power consumption in processing And the electricity consumption of storage represents the fuel consumption of the park on the kth day, Including fuel consumption in the collection of raw materials Fuel consumption in the processing stage Fuel consumption in storage s represents the time point corresponding to the single-day energy consumption data, and d = s;

[0018] Calculate the productivity Scl, as shown in formula (1):

[0019]

[0020] Where: It represents the proportional relationship between the production and operation data and water consumption of the raw material collection, processing and storage links of the park on the kth day under the i-th production and operation mode; It represents the ratio of production operation data and electricity consumption in the raw material collection, processing and storage links of the park on the kth day under the i-th production operation mode; It represents the proportional relationship between the production operation data and fuel consumption of the raw material collection, processing and warehousing links of the park on the kth day under the i-th production operation mode.

[0021] Further, in step 4, the net zero index Jlzs is calculated as follows:

[0022] According to the production and operation data of the park on the kth day, the carbon emissions and carbon capture of the park on the kth day in the emission data set are extracted and marked as The calculation formula of the net zero index Jlzs is as follows:

[0023]

[0024] Where: Tkl p Tkl represents the carbon emissions of the park at the lth hour on the kth day, b It represents the carbon capture amount of the park at the lth hour on the kth day, and 24 represents the constant in the calculation formula of the net zero index.

[0025] Furthermore, in step 4, the calculation steps of the net carbon data set Jtsj are as follows:

[0026] According to the carbon emissions and carbon capture of the park every hour, the net carbon emissions of the park every hour are calculated. The calculation formula is as follows:

[0027] Jt l =Tkl p -Tkl b (3)

[0028] Where: Jt l represents the net carbon emissions of the park at the lth hour on the kth day;

[0029] According to the hourly net carbon emissions of the park, the net carbon data group Jtsj is analyzed and generated, as shown in formula (4):

[0030]

[0031] Where: Jtsj represents the net carbon data set, Jt max represents the highest net carbon emission of the park in a single hour on the kth day, Jt min represents the lowest net carbon emissions of the park in a single hour on the kth day, It represents the average value of net carbon emissions of the park on the kth day.

[0032] Furthermore, in the step five, the energy consumption threshold includes a water consumption threshold SY, an electricity consumption threshold DY and a fuel threshold RY; the daily water consumption, electricity consumption and fuel consumption of the park under the i-th production and operation mode are compared with the water consumption threshold SY, the electricity consumption threshold DY and the fuel threshold RY respectively. If any one of the values ​​of the park's daily water consumption, electricity consumption and fuel consumption exceeds the corresponding energy consumption threshold, it means that the park's energy consumption on that day exceeds the standard. The number of days when the park's energy consumption exceeds the standard under the i-th production and operation mode is counted and marked as NC. If NC≥XT, then under the i-th production and operation mode, the risk level of carbon neutrality imbalance in the park is judged to be high risk.

[0033] Furthermore, in step five, the productivity Scl under the i-th production operation mode is compared with the standard productivity Bcl. If the productivity Scl is different from the standard productivity Bcl, it indicates that there is an imbalance in the energy configuration of each link in the production chain of the park.

[0034] Furthermore, in the step six, the net zero index Jlzs and net carbon data group Jtsj under the i-th production and operation mode are compared with the set index threshold ZY and net carbon threshold JTY respectively. If any value of the net zero index Jlzs and the net carbon data group Jtsj exceeds the index threshold ZY and the net carbon threshold JTY, it indicates that the carbon neutrality effect of the park is not good.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] (1) The present invention connects to the park management platform through the network to comprehensively and in real time obtain daily operation data and energy consumption data under various production and operation modes, and calculates the productivity under various production and operation modes. It further compares the energy consumption data with the energy consumption threshold to determine whether the park's energy consumption exceeds the standard, and then determines the risk level of carbon neutrality imbalance in the park based on the number of days exceeding the standard, thereby truly reflecting the energy efficiency of the park on that day and avoiding the "greenwashing" behavior of only offsetting carbon emissions without actual emission reduction during park management. At the same time, it determines whether there is an imbalance in the energy configuration of each link in the park's production chain by comparing the productivity with the standard productivity, providing guidance for energy conservation and emission reduction control in each link of the production chain, and promptly reminding management personnel to adjust the production and operation mode in a targeted manner to truly achieve source control.

[0037] (2) The present invention obtains the hourly carbon emissions and carbon capture of the park in real time through a network-connected sensor device, and analyzes and generates a net zero index and a net carbon data group corresponding to various production and operation modes, and further compares them with the index threshold and the net carbon threshold respectively, so as to dynamically evaluate the carbon neutrality effect of the park, and reflect the carbon neutrality of the park under various production and operation modes in real time, which complements the judgment of whether the energy configuration of each link in the production chain is unbalanced, and can greatly improve the rating accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Figure 1 The present invention is a flow chart of an evaluation method for carbon neutrality in a park, illustrating an example. DETAILED DESCRIPTION

[0039] In order to make the technical problems and technical solutions solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] like Figure 1As shown, this embodiment provides a method for evaluating carbon neutrality in a park, and the method includes the following steps:

[0041] Step 1: Connect to the park management platform through the network to obtain the park's daily production operation data and energy consumption data, and classify the acquired data into operation data sets and consumption data sets.

[0042] Specifically, the expression of the operation data set is to They correspond to the daily production and operation data of the park, which include raw material collection volume, processing output and storage volume. d represents the time point corresponding to the single-day production and operation data, m represents the single-day production and operation mode, and 1 to x represent that there are x groups of production and operation data obtained.

[0043] The expression for consuming the data set is {N1 s 、N2 s 、N3 s , ..., Nx s},N1 s To Nx s They correspond to the daily energy consumption data of the park, which include water consumption, electricity consumption and fuel consumption; s represents the time point corresponding to the daily energy consumption data, and 1 to x represents that there are x groups of energy consumption data obtained.

[0044] Under different production and operation modes, the park's production capacity and energy consumption are different. Comprehensive collection of daily production and operation data and energy consumption data will help to accurately judge the risk level of carbon neutrality imbalance in the park under different production and operation modes, and evaluate whether there is an imbalance in the energy configuration of each link in the park's production chain.

[0045] Step 2: Use the network to connect the sensor devices to obtain the hourly carbon emissions and carbon capture of the park, and form the obtained data into an emission data set.

[0046] Specifically, the expression of the emission data set is to They correspond to the hourly carbon emissions and carbon capture of the park respectively, p represents the hourly carbon emissions of the park, b represents the hourly carbon capture of the park, and 1 to h represent that there are h groups of carbon emissions and carbon capture obtained.

[0047] Carbon emissions and carbon capture directly reflect the carbon neutrality management effect of the park. Real-time collection of the park's hourly emission data is conducive to the subsequent analysis of carbon emission trends in different time periods.

[0048] Step 3: Based on the operation data set and the consumption data set, analyze the proportional relationship between the park's production operation data and energy consumption data under different production operation modes, and generate the corresponding productivity Scl. The calculation steps are as follows:

[0049] Extract the production and operation data of the park on the kth day under the i-th production and operation mode in the operation data set and mark it as represents the amount of raw materials collected in the park on the kth day, represents the processing output of the park on the kth day, represents the storage volume of the park on the kth day, and d represents the time point corresponding to the single-day production and operation data;

[0050] According to the production and operation data of the park on the kth day, the energy consumption data of the park on the kth day in the consumption data set is extracted and marked as represents the water consumption of the park on the kth day, Including water consumption in the collection of raw materials Water consumption in processing and water consumption in storage represents the electricity consumption of the park on the kth day, Including electricity consumption in the raw material collection process Power consumption in processing And the electricity consumption of storage represents the fuel consumption of the park on the kth day, Including fuel consumption in the collection of raw materials Fuel consumption in the processing stage Fuel consumption in storage s represents the time point corresponding to the single-day energy consumption data, and d = s;

[0051] Calculate the productivity Scl, as shown in formula (1):

[0052]

[0053] Where: It represents the proportional relationship between the production and operation data and water consumption of the raw material collection, processing and storage links of the park on the kth day under the i-th production and operation mode; It represents the ratio of production operation data and electricity consumption in the raw material collection, processing and storage links of the park on the kth day under the i-th production operation mode; It represents the proportional relationship between the production operation data and fuel consumption of the raw material collection, processing and warehousing links of the park on the kth day under the i-th production operation mode.

[0054] According to the above calculation process, the productivity Scl under each production operation mode can be analyzed by analogy.

[0055] Step 4: Based on the emission data set, analyze the balance trend of carbon emissions and carbon capture in the park on a single day and generate the corresponding net zero index Jlzs, which is calculated as follows:

[0056] According to the production and operation data of the park on the kth day, the carbon emissions and carbon capture of the park on the kth day in the emission data set are extracted and marked as The calculation formula of the net zero index Jlzs is as follows:

[0057]

[0058] Where: Tkl p Tkl represents the carbon emissions of the park at the lth hour on the kth day, b It represents the carbon capture amount of the park at the lth hour on the kth day, and 24 represents the constant in the calculation formula of the net zero index.

[0059] Furthermore, based on the carbon emissions and carbon capture of the park every hour on the kth day, the net carbon emissions of the park every hour on the kth day are calculated using the following formula (3):

[0060] Jt l =Tkl p -Tkl b (3)

[0061] Where: Jt l represents the net carbon emissions of the park at the lth hour on the kth day;

[0062] Furthermore, according to the hourly net carbon emissions of the park, the net carbon data group Jtsj is analyzed and generated, as shown in formula (4):

[0063]

[0064] Where: Jtsj represents the net carbon data set, Jt max represents the highest net carbon emission of the park in a single hour on the kth day, Jt min represents the lowest net carbon emissions of the park in a single hour on the kth day, It represents the average value of net carbon emissions of the park on the kth day.

[0065] According to the above calculation process, and by analogy, the net zero index Jlzs and net carbon data group Jtsj under each production operation mode are analyzed to comprehensively analyze the carbon neutrality effect of the park, which will help managers to optimize and transform the energy management, energy conservation and emission reduction technical measures in each link of the industrial production chain in a targeted manner.

[0066] Step 5: Set a fixed range of energy consumption thresholds, a fixed value of restricted days XT, and a fixed value of standard productivity Bcl, and combine the consumption data set and productivity Scl to determine the risk level of carbon neutrality imbalance in the park, and evaluate whether there is an imbalance in the energy configuration of each link in the park's production chain.

[0067] Specifically, the energy consumption thresholds include a water consumption threshold SY, an electricity consumption threshold DY, and a fuel consumption threshold RY.

[0068] The daily water consumption, electricity consumption, and fuel consumption of the park under the i-th production and operation mode are compared with the water consumption threshold SY, electricity consumption threshold DY, and fuel threshold RY respectively. If any value of the park's daily water consumption, electricity consumption, and fuel consumption exceeds the corresponding energy consumption threshold, it means that the park's energy consumption on that day exceeds the standard.

[0069] At this time, the number of days when the park's energy consumption exceeds the standard under the i-th production and operation mode is counted and marked as NC. If NC ≥ XT, the risk level of carbon neutrality imbalance in the park under the i-th production and operation mode is judged to be high risk. The number of days when energy consumption exceeds the standard NC can truly reflect the energy efficiency of the park on that day, thereby avoiding the "greenwashing" behavior of only offsetting carbon emissions without actual emission reductions during park management.

[0070] Compare the productivity Scl under the i-th production operation mode with the standard productivity Bcl. If the productivity Scl is different from the standard productivity Bcl, it means that there is an imbalance in the energy configuration of each link in the park's production chain, and the management personnel can be reminded in time to adjust the production operation mode in a targeted manner.

[0071] Step six: Set a fixed range of index threshold ZY and net carbon threshold JTY, and compare the net zero index Jlzs and net carbon data group Jtsj under the i-th production and operation mode with the set index threshold ZY and net carbon threshold JTY respectively. If any value of the net zero index Jlzs and the net carbon data group Jtsj exceeds the index threshold ZY and the net carbon threshold JTY, it means that the carbon neutrality effect of the park is not good. This dynamic assessment is more accurate.

[0072] It should be understood that the serial numbers of the steps in the above embodiments do not imply a sequence of execution, and the execution sequence of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.
