Description

Technical Field

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

[0002] Industrial parks carry the production and operation activities of enterprises and have important economic and social significance. Traditional industrial production processes are usually accompanied by a large amount of carbon emissions and other environmental pollutants, showing problems such as high energy consumption and high carbon emissions, which have an adverse impact on climate change and environmental quality. Therefore, in order to meet the challenges of climate change and achieve sustainable development goals, it is urgent to guide the carbon emission management of industrial parks.

[0003] The existing carbon emission evaluation system in industrial parks is not sound. The evaluation methods of some parks are too simplified, and may only consider direct energy consumption, while ignoring other important emission sources, such as process emissions and fugitive emissions. On the contrary, some evaluation methods are too complicated and require professional knowledge and advanced analysis tools, making it difficult for ordinary parks to implement, increasing the cost and time of evaluation. Therefore, the existing evaluation methods are too simple or complex, and it is difficult to accurately reflect the carbon emission level and emission reduction effect of the park, and it is impossible to effectively guide the energy conservation and emission reduction of the park. Summary of the invention

[0004] The present invention provides a park carbon emission management method to solve the technical problem that the existing park carbon emission evaluation system is difficult to accurately reflect the park's carbon emission level and emission reduction effect.

[0005] In order to solve the above technical problems, an embodiment of the present invention provides a park carbon emission management method, the method comprising:

[0006] Collecting park basic data and preprocessing the park basic data;

[0007] Obtain the preset park carbon emission baseline value and carbon emission design value;

[0008] Obtain a preset carbon emission calculation model, calculate the carbon emission of the park basic data according to the carbon emission calculation model, obtain the actual value of carbon emission, and visualize and analyze the result;

[0009] By comparing the actual carbon emission value with the carbon emission design value and the carbon emission baseline value, abnormal operation data can be tracked and warned;

[0010] Based on the actual carbon emission value and the carbon emission benchmark value, the carbon efficiency evaluation index is calculated;

[0011] Based on the current carbon emission intensity and the previous carbon emission intensity, the emission reduction evaluation index is calculated;

[0012] Based on the emission reduction of external energy, carbon sink, carbon emission trading volume, building carbon emission, public facility carbon emission, transportation carbon emission and waste treatment carbon emission, the neutralization evaluation index is calculated;

[0013] The carbon emission management of the park is carried out according to the comparison results of the actual carbon emission value with the carbon emission design value, the carbon emission baseline value, the carbon efficiency evaluation index, the emission reduction evaluation index and the neutralization evaluation index.

[0014] Furthermore, the carbon efficiency evaluation index includes a carbon efficiency value, where the carbon efficiency value = actual carbon emission value / carbon emission baseline value. If the carbon efficiency value is greater than 1, it indicates that the carbon emission intensity of the park is higher than the regional / industry average and there is a large room for emission reduction.

[0015] Furthermore, the emission reduction evaluation index includes the park's carbon emission intensity reduction rate, and the park's carbon emission intensity reduction rate = ((T-1) carbon emission intensity - T carbon emission intensity) / (T-1) carbon emission intensity * 100%, where T is time. The greater the park's carbon emission intensity reduction rate, the better the park's energy conservation and emission reduction effect.

[0016] Furthermore, the neutralization evaluation index includes the carbon neutrality rate of the park, and the carbon neutrality rate of the park = (external energy emission reduction + carbon sink + carbon emission trading volume) / (building carbon emissions + public facility carbon emissions + transportation carbon emissions + waste treatment carbon emissions) * 100%, wherein, when the carbon neutrality rate of the park is greater than or equal to 100%, it means that the park has achieved carbon neutrality.

[0017] Furthermore, the specific steps of tracking and warning abnormal operation data by comparing the actual carbon emission value with the carbon emission design value and the carbon emission baseline value include:

[0018] By comparing the actual carbon emission value with the carbon emission design value and the carbon emission baseline value, abnormal operation data can be tracked and warned;

[0019] When the actual carbon emission value is greater than the carbon emission benchmark value, a data warning is provided to the user, and the specific time and deviation ratio are displayed to remind the user to take urgent emission reduction measures;

[0020] When the carbon emission design value is less than the carbon emission actual value and less than the carbon emission baseline value, data tracking is continued and the park emission reduction is calculated, where the park emission reduction = carbon emission baseline value - carbon emission actual value;

[0021] When the actual carbon emission value is less than the designed carbon emission value, the system will provide users with data warnings and display the specific time and deviation ratio to remind users to check whether there is equipment failure or low-load operation.

[0022] Furthermore, the specific steps of collecting the park basic data include:

[0023] The basic data of the park is collected through automatic collection by metering equipment and manual online reporting.

[0024] Furthermore, the metering equipment automatically collects data from a unified support service platform, and the unified support service platform aggregates basic data of the park's source-grid-load-storage dispatching system and the park's intelligent management system. The park's source-grid-load-storage dispatching system automatically collects electricity consumption data of various buildings, systems, key areas and key equipment in the park through electricity meters. The park's intelligent management system automatically collects water consumption, natural gas consumption, vehicle entry and exit, vehicle ownership, personnel entry and exit, and personnel ownership information of various buildings, systems, key areas and key equipment in the park through water meters, natural gas meters, heat meters, vehicle identification systems, and personnel identification systems.

[0025] Furthermore, the manual online reporting includes online reporting of park properties and online reporting of park enterprises. The information reported online for park properties includes park trash can models, garbage processing volume, park greening area, park greening types, park carbon trading volume, and oil consumption. The information reported online by park enterprises includes basic enterprise information and enterprise output value data.

[0026] The embodiment of the present invention further provides a park carbon emission management system, the system comprising:

[0027] The carbon monitoring unit includes a collection module and a carbon emission calculation module. The collection module is used to collect basic data of the park, pre-process the basic data of the park, and obtain a preset park carbon emission baseline value, a carbon emission design value and a carbon emission calculation model; the carbon emission calculation module is used to calculate the carbon emission of the basic data of the park according to the carbon emission calculation model, obtain the actual value of carbon emission, and visualize and analyze the results;

[0028] The carbon evaluation unit includes a carbon emission benchmarking module, a carbon efficiency evaluation module, an emission reduction evaluation module and a neutralization evaluation module. The carbon emission benchmarking module is used to compare the actual carbon emission value with the carbon emission design value and the carbon emission baseline value, and track and warn abnormal operation data; the carbon efficiency evaluation module is used to calculate the carbon efficiency evaluation index based on the actual carbon emission value and the carbon emission baseline value; the emission reduction evaluation module is used to calculate the emission reduction evaluation index based on the current carbon emission intensity and the previous carbon emission intensity; the neutralization evaluation module is used to calculate the neutralization evaluation index based on the external energy emission reduction, carbon sink, carbon emission trading volume, building carbon emissions, public facility carbon emissions, transportation carbon emissions and waste treatment carbon emissions;

[0029] The carbon emission management unit is used to manage the carbon emissions of the park according to the comparison results of the actual carbon emission value with the carbon emission design value, the carbon emission baseline value, the carbon efficiency evaluation index, the emission reduction evaluation index and the neutralization evaluation index.

[0030] Beneficial effects of the embodiments of the present invention:

[0031] This example can provide users with early warnings by comparing the actual carbon emission values ​​with the carbon emission design values ​​and the carbon emission baseline values, reminding them to take emission reduction measures or check whether the equipment is faulty or running at low load, thereby achieving carbon emission management.

[0032] The present invention conducts carbon efficiency evaluation, emission reduction evaluation and neutralization evaluation on the park according to the indicator results of carbon efficiency evaluation index, emission reduction evaluation index and neutralization evaluation index, wherein the indicator results will correspond to the corresponding evaluation results. Specifically, if the carbon efficiency value is greater than 1, it indicates that the carbon emission intensity of the park is higher than the regional / industry average level, and there is a large emission reduction space; the greater the reduction rate of the park's carbon emission intensity, the better the energy conservation and emission reduction effect of the park; when the park's carbon neutralization rate is greater than or equal to 100%, it means that the park has achieved carbon neutrality. According to the evaluation results, the emission reduction space and emission reduction effect can be intuitively and accurately understood, and the evaluation results can be used as indicators to guide the energy conservation and emission reduction of the park.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] Please refer to Figure 1-3, a park carbon emission management method provided by an embodiment of the present invention, the method comprising:

[0040] S10: Collecting park basic data and preprocessing the park basic data;

[0041] S20: Obtaining a preset park carbon emission baseline value and a carbon emission design value;

[0046] S70: Neutralization evaluation indicators are calculated based on the reduction of external energy emissions, carbon sinks, carbon emissions trading volume, building carbon emissions, public facility carbon emissions, transportation carbon emissions and waste treatment carbon emissions.

[0047] S80: Carry out carbon emission management in the park based on the comparison results of actual carbon emission values ​​with design carbon emission values, carbon emission baseline values, carbon efficiency evaluation indicators, emission reduction evaluation indicators and neutralization evaluation indicators.

[0048] In a specific embodiment, taking an office park in Xiong'an as an example, the "Xiong'an New Area Park Carbon Emission Accounting Standard Part 1: Public Building Park" DB1331 / T 068-2023 can be selected, and the carbon emission calculation model is preset according to the carbon emission calculation formula in the standard, and the carbon emission calculation model is used to calculate the carbon emission of the park basic data to obtain the actual value of carbon emissions. The calculation results can be displayed on the display screen or output as a document for viewing, which is convenient for carbon emission analysis.

[0049] Specifically, the actual value of carbon emissions refers to the cumulative value of carbon emissions from all carbon emission sources in the park (such as electricity, heat, transportation, etc.). In this embodiment, the actual value of carbon emissions is calculated based on a preset carbon emission calculation model.

[0050] Specifically, the carbon emission value of the same type of parks in the region or industry in the standard is the carbon emission baseline value.

[0051] Specifically, the carbon emission design value is calculated based on the operating data under the design conditions of the park.

[0052] like Figure 3 As shown, specifically, the specific steps of collecting park basic data in step S10 include:

[0053] The basic data of the park is collected through automatic collection by metering equipment and manual online reporting. The basic data of the park is collected by a unified support service platform, park properties and park enterprises.

[0054] Specifically, the metering equipment automatically collects data from a unified support service platform, which aggregates basic data from the park's source-grid-load-storage dispatching system and the park's intelligent management system.

[0055] The park source-grid-load-storage dispatching system automatically collects electricity consumption data of each building, system, key area and key equipment in the park through electricity meters. The data is calculated according to the preset carbon emission calculation model to obtain the carbon emissions of electricity of each building, system, key area and key equipment in the park, as well as the carbon emissions generated by energy transported outside the park, such as car charging piles and renewable energy surplus power transmission.

[0056] The park's intelligent management system automatically collects information on water usage, natural gas usage, vehicle in and out, vehicle ownership, personnel in and out, and personnel ownership of each building, system, key area, and key equipment in the park through water meters, natural gas meters, heat meters, vehicle identification systems, and personnel identification systems. The data is calculated based on the preset carbon emission calculation model to obtain carbon emissions from domestic sewage treatment, fossil fuel combustion, heat, and transportation in the park, as well as the carbon emission intensity of park units and personnel.

[0057] Specifically, manual online reporting includes online reporting of park properties and online reporting of park enterprises.

[0058] The information reported online by the park property includes the model of the park's trash can, the amount of garbage processed, the park's green area, the type of park greening, the park's carbon trading volume, and the amount of oil used. By calculating this data based on the preset carbon emission calculation model, we can obtain the carbon emissions generated by the park's solid waste treatment, the park's carbon sink, and the carbon emissions from fuel.

[0059] The information reported online by enterprises in the park includes basic information of the enterprise and the output value data of the enterprise. The data is used to calculate the carbon emission intensity per unit output value of the park.

[0060] Preferably, after the park basic data is collected, the park basic data is preprocessed.

[0061] The preprocessing of the park's basic data includes data cleaning, data integration, data transformation, etc. Data cleaning is specifically to identify and correct errors and inconsistencies in the data, such as filling or deleting missing values, outliers, duplicate values, etc., to improve the accuracy and reliability of the data; data integration is specifically to convert data in different formats into a unified format and merge them together to form a unified data set; data transformation is specifically to convert data into numerical values ​​with the same dimension and magnitude to improve the processability and interpretability of the data.

[0062] like Figure 2 As shown, the specific steps of step S40 include:

[0063] When the actual carbon emission value is greater than the carbon emission benchmark value, it provides users with data warnings and displays the specific time and deviation ratio to remind users to take urgent emission reduction measures;

[0064] When the carbon emission design value is less than the actual carbon emission value and less than the carbon emission benchmark value, the data will be continuously tracked and the emission reduction of the park will be calculated. The emission reduction of the park = the carbon emission benchmark value - the actual carbon emission value;

[0065] When the actual carbon emission value is less than the designed carbon emission value, the system will provide users with data warnings and display the specific time and deviation ratio to remind users to check whether there is equipment failure or low-load operation.

[0066] In a specific embodiment, taking an office park in Xiongan as an example, the benchmark value is selected as the 2020 Hebei Province office building baseline carbon emission intensity of 86.8kgCO2 / m 2 a. The design value is the carbon emission intensity calculated under the design conditions of the park, 30kgCO2 / m 2 a, if the actual carbon emission value of the park in that year is 100kgCO2 / m 2 a, that is, the actual carbon emission value is greater than the carbon emission benchmark value, then a data warning is provided to the user, and the specific time and deviation ratio are displayed to remind the user to take urgent emission reduction measures; if the actual carbon emission value of the park in that year is 50kgCO2 / m 2 a, that is, when the carbon emission design value is less than the actual carbon emission value and less than the carbon emission baseline value, data tracking will continue, and the emission reduction of the park is 36.8kgCO2 / m 2 a; If the actual carbon emission value of the park in that year is 10kgCO2 / m 2 a, that is, when the actual carbon emission value is less than the designed carbon emission value, a data warning will be provided to the user, and the specific time and deviation ratio will be displayed to remind the user to check whether there is equipment failure or low-load operation.

[0067] This embodiment compares the actual carbon emission value with the carbon emission design value and the carbon emission baseline value, and can provide early warning to users, reminding them to take emission reduction measures or check whether the equipment is faulty or running at low load. The actual carbon emission value is displayed visually, which can make users more intuitive and easier to perceive abnormal data, making it convenient for users to perform corresponding maintenance on the equipment that generates the abnormal data.

[0068] In this embodiment, the carbon efficiency evaluation index, the emission reduction evaluation index and the neutralization evaluation index are calculated based on the park basic data collected in the above step S10.

[0069] Specifically, carbon efficiency evaluation indicators include carbon efficiency value, carbon efficiency value = actual carbon emission value / carbon emission baseline value. If the carbon efficiency value is greater than 1, it means that the carbon emission intensity of the park is higher than the regional / industry average and there is a large room for emission reduction.

[0070] Specifically, the emission reduction evaluation indicators include the park's carbon emission intensity reduction rate, which is ((T-1) carbon emission intensity-T carbon emission intensity) / (T-1) carbon emission intensity*100%), where T is time. The greater the park's carbon emission intensity reduction rate, the better the park's energy conservation and emission reduction effect.

[0071] More specifically, based on the basic information and output value data reported online by the park enterprises, the data is calculated according to the preset carbon emission calculation model to obtain the carbon emission intensity per unit output value of the park.

[0072] Specifically, the neutralization evaluation indicators include the carbon neutrality rate of the park, which is (external energy emission reduction + carbon sink + carbon emission trading volume) / (building carbon emissions + public facility carbon emissions + transportation carbon emissions + waste treatment carbon emissions) * 100%. When the park's carbon neutrality rate is greater than or equal to 100%, it means that the park has achieved carbon neutrality.

[0073] More specifically, the emission reduction of external energy can be calculated based on the electricity consumption data collected by electricity meters, such as car charging piles and external transmission of surplus power from renewable energy, to obtain the carbon emissions generated by the energy transmitted from the park. The difference within a certain period of time is the emission reduction of external energy.

[0074] The carbon sink amount can be calculated based on the park greening area and park greening types reported online by the park property.

[0075] The carbon emission trading volume is the park carbon trading volume reported online by the park properties.

[0076] Building carbon emissions can be calculated based on the electricity consumption data of each building collected by electricity meters, and can also be calculated based on data such as water consumption, natural gas consumption, personnel entry and exit, and personnel affiliation information of each building collected by water meters, natural gas meters, heat meters, and personnel identification systems.

[0077] The carbon emissions of public facilities can be calculated based on the electricity carbon emissions of various systems, key areas and key equipment collected by electricity meters, as well as the water consumption, natural gas consumption, personnel entry and exit, and personnel affiliation information of various systems, key areas and key equipment collected by water meters, natural gas meters, heat meters and personnel identification systems.

[0078] Transportation carbon emissions can be calculated based on data collected by the vehicle identification system on vehicle entry and exit, vehicle ownership, and fuel consumption reported online by park properties.

[0079] Carbon emissions from waste treatment can be calculated based on data such as park trash can models and waste treatment volumes reported online by the park property.

[0080] In a specific embodiment, taking an office park in Xiongan as an example, the benchmark value is selected as the 2020 Hebei Province office building baseline carbon emission intensity of 86.8kgCO2 / m 2 a, if the actual carbon emission value of the park in that year is 100kgCO2 / m 2 a, then the carbon efficiency value is 1.15, and the carbon efficiency value is greater than 1, indicating that the carbon emission intensity of the park is higher than the regional / industry average level, and there is a large room for emission reduction.

[0081] If the carbon emissions of the park are 100kgCO2 / m 2 a. In 2023, the carbon emissions of the park will be 80kgCO2 / m 2 a, the park's carbon emission intensity reduction rate is 20%, which represents the change in the park's carbon emission intensity compared with the previous period. The greater the park's carbon emission intensity reduction rate, the better the park's energy conservation and emission reduction effect.

[0082] If the park's external energy emission reduction in 2023 is 0tCO2, the carbon sink is 100tCO2, the purchase of CCER (Certified Voluntary Emission Reductions, CCER) is 500tCO2, the building carbon emissions are 400tCO2, the carbon emissions of public facilities such as street lights and pump rooms in the park are 200tCO2, the carbon emissions of transportation in the park are 50tCO2, and the carbon emissions of solid waste and domestic sewage treatment in the park are 100tCO2, then the park's carbon neutrality rate is 80%. The carbon neutrality rate represents the park's carbon neutrality process. When the carbon neutrality rate is greater than or equal to 100%, it means that the park has achieved carbon neutrality.

[0083] The carbon emission collection method of the present invention combines automatic collection by metering equipment with manual online reporting. The information reported manually only needs to fill in data that cannot be directly obtained by the equipment, such as waste treatment and enterprise output value data, which greatly reduces the workload of manual reporting of information.

[0084] This example can provide users with early warnings by comparing the actual carbon emission values ​​with the carbon emission design values ​​and the carbon emission baseline values, reminding them to take emission reduction measures or check whether the equipment is faulty or running at low load, thereby achieving carbon emission management. Combined with carbon efficiency evaluation indicators, emission reduction evaluation indicators and neutralization evaluation indicators, the carbon emission situation can be further confirmed, whether the carbon emission management is reasonable can be clarified, and carbon emission management can be assisted.

[0085] The present invention conducts carbon efficiency evaluation, emission reduction evaluation and neutralization evaluation on the park according to the indicator results of carbon efficiency evaluation index, emission reduction evaluation index and neutralization evaluation index, wherein the indicator results will correspond to the corresponding evaluation results. Specifically, if the carbon efficiency value is greater than 1, it indicates that the carbon emission intensity of the park is higher than the regional / industry average level, and there is a large emission reduction space; the greater the reduction rate of the park's carbon emission intensity, the better the energy conservation and emission reduction effect of the park; when the park's carbon neutralization rate is greater than or equal to 100%, it means that the park has achieved carbon neutrality. According to the evaluation results, the emission reduction space and emission reduction effect can be intuitively and accurately understood, and the evaluation results can be used as indicators to guide the energy conservation and emission reduction of the park.
