Description

Technical Field

[0001] This invention relates to the field of regional carbon emission technology, specifically to a method, apparatus, equipment, and storage medium for calculating the carbon footprint factor of a regional power grid. Background Technology

[0002] A carbon footprint refers to the total amount of carbon dioxide and other greenhouse gases emitted by a product or service throughout its entire life cycle. The entire life cycle refers to the continuous and interconnected stages related to the product, from the acquisition of raw materials or the generation of raw materials from natural resources to their end-of-life disposal.

[0003] The regional electricity carbon footprint factor typically refers to the greenhouse gas emissions of a user using 1 kWh of electricity over its entire lifecycle within the power grid supply area of ​​a specific region. Currently, most calculations of the electricity carbon footprint factor are based on large-scale, macroscopic models, without considering the impact of refined factors such as geographical location on carbon emissions. This results in the calculation results of the electricity carbon footprint factor failing to accurately represent the distribution of the electricity carbon footprint within the region. Summary of the Invention

[0004] The purpose of this invention is to provide a method, apparatus, equipment, and medium for calculating the carbon footprint factor of a regional power grid. By using benchmark data for calculating the carbon footprint of electricity within the region, the carbon footprint of electricity is calculated from different perspectives and using different principles, thus refining the granularity of the calculation and solving the problem that the current calculation results of the carbon footprint factor of electricity cannot accurately represent the distribution of the carbon footprint of electricity within the region.

[0005] This invention is achieved through the following technical solution:

[0006] The first aspect of this application provides a method for calculating the carbon footprint factor of a regional power grid, including:

[0007] To obtain a benchmark data system for calculating the electricity carbon footprint of regional power grids;

[0008] Based on the preset calculation method, the data required by the calculation method are selected from the benchmark data system to calculate the electricity carbon footprint factor;

[0009] The calculation methods include any one of the following: carbon footprint allocation based on user electricity consumption within the region, carbon footprint allocation based on total user electricity consumption, carbon footprint factor weighting based on the proportion of electricity structure considering the impact of transfers in and out, and carbon footprint factor weighting based on the proportion of electricity structure considering the impact of transfers in.

[0010] In one feasible implementation, if the calculation method is based on the allocation of carbon footprint according to the electricity consumption of users within a region, then the data required for the calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor, specifically including:

[0011] Electricity data and background carbon footprint factor data are selected from the aforementioned benchmark data system; the electricity data includes the power generation and grid connection of each type of power in the region, the electricity transferred into the region, the electricity transferred out of the region, and the electricity consumption of users in the region; the background carbon footprint factor data includes the carbon footprint factor of each type of power and the carbon footprint factor of power transmission and distribution.

[0012] The first total carbon footprint of the region is calculated by subtracting the carbon footprint of outgoing electricity from the sum of the carbon footprints of power generation and grid connection within the region, the carbon footprints of incoming electricity, and the carbon footprints of electricity consumption by users within the region. The carbon footprints of power generation and grid connection, incoming electricity, and outgoing electricity within the region are all determined by multiplying the electricity data corresponding to each type of electricity within the region with the carbon footprint factor of the corresponding type of electricity. The carbon footprint of electricity consumption by users within the region is determined by the electricity consumption of users within the region and the carbon footprint factor of power transmission and distribution.

[0013] The ratio of the total first carbon footprint in the region to the electricity consumption of users in the region is used as the first electricity carbon footprint factor.

[0014] In one feasible implementation, the power type includes at least wind power, solar power, thermal power, and hydropower.

[0015] In one feasible implementation, if the calculation method is based on the allocation of carbon footprint according to total user electricity consumption, then the data required for the calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor, specifically including:

[0016] Electricity data and background carbon footprint factor data are selected from the aforementioned benchmark data system; the electricity data includes the power generation and grid connection of each type of power in the region, the electricity transferred into the region, the electricity transferred out of the region, and the electricity consumption of users in the region; the background carbon footprint factor data includes the carbon footprint factor of each type of power and the carbon footprint factor of power transmission and distribution.

[0017] The total second carbon footprint of the region is the sum of the carbon footprints of power generation and grid connection within the region, the carbon footprints of electricity transferred into the region, and the carbon footprints of electricity consumption by users within the region. The carbon footprints of power generation and grid connection within the region and the carbon footprints of electricity transferred into the region are determined by multiplying the electricity data corresponding to each type of power within the region with the carbon footprint factor of the corresponding type of power. The carbon footprint of electricity consumption by users within the region is determined by the electricity consumption by users within the region and the carbon footprint factor of power transmission and distribution.

[0018] The ratio of the total second carbon footprint within the region to the total electricity consumption of users within the region is used as the second electricity carbon footprint factor; the total electricity consumption of users within the region is the sum of electricity consumption of users within the region and electricity transferred out of the region.

[0019] In one feasible implementation, if the calculation method is a weighted average of the carbon footprint factor based on the proportion of electricity volume structure considering the impact of transfer in and out, then the data required for the calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor, specifically including:

[0020] Electricity data and background carbon footprint factor data are selected from the aforementioned benchmark data system. Electricity data includes the power generation and grid connection of each power type, the electricity transferred into the region, the electricity transferred out of the region, and the average line loss rate within the region. Background carbon footprint factor data includes the carbon footprint factor of each power type and the carbon footprint factor of power transmission and distribution.

[0021] The carbon footprint factor of each power type is weighted by the proportion of the first power structure of each power type. The weighted sum is then summed with the carbon footprint factor of transmission and distribution to obtain the first power structure weighted carbon footprint factor. The first power structure weighted carbon footprint factor is then added to the product of the first power structure weighted carbon footprint factor and the average line loss rate to obtain the third power carbon footprint factor.

[0022] The proportion of the first power volume structure of each power type is determined by the ratio of the first power volume of the target power type in the region to the first power volume of all power types in the region. The first power volume of the target power type in the region is the sum of the power generation and grid connection of the target power type in the region and the power transfer in the region minus the power transfer out of the target power type in the region. The first power volume of all power types in the region is the sum of the power generation and grid connection of each power type in the region and the power transfer in the region minus the power transfer out of the region.

[0023] In one feasible implementation, if the calculation method is a weighted average of the electricity structure proportion considering the impact of transfers on the carbon footprint factor, then the data required for the calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor, specifically including:

[0024] Electricity data and background carbon footprint factor data are selected from the aforementioned benchmark data system; the electricity data includes the power generation and grid connection of each power type, the power transferred into the region, and the average line loss rate in the region; the background carbon footprint factor data includes the carbon footprint factor of each power type and the carbon footprint factor of power transmission and distribution.

[0025] The carbon footprint factor of the corresponding power type is weighted by the proportion of the second power structure of each power type. The weighted sum is summed with the carbon footprint factor of transmission and distribution to obtain the second power structure weighted carbon footprint factor. The second power structure weighted carbon footprint factor is added to the product of the second power structure weighted carbon footprint factor and the average line loss rate to obtain the fourth power carbon footprint factor.

[0026] The proportion of the second power volume structure of each power type is determined by the ratio of the second power volume of the target power type in the region to the second power volume of all power types in the region; the second power volume of the target power type in the region is the sum of the power generation and grid connection of the target power type in the region and the power transfer in the region; the second power volume of all power types in the region is the sum of the power generation and grid connection of each power type in the region and the power transfer in the region.

[0027] In one feasible implementation, the method further includes: selecting an accounting method suitable for the target scenario from among various accounting methods based on the accounting starting point and the impact of inter-regional power allocation on the power structure.

[0028] The second aspect of this application provides a device for calculating the carbon footprint factor of a regional power grid, comprising:

[0029] The data acquisition unit is used to acquire a benchmark data system for calculating the electricity carbon footprint of the regional power grid.

[0030] The calculation unit, based on a preset calculation method, selects the data required by the calculation method from the benchmark data system to calculate the electricity carbon footprint factor;

[0031] The calculation methods include any one of the following: carbon footprint allocation based on user electricity consumption within the region, carbon footprint allocation based on total user electricity consumption, carbon footprint factor weighting based on the proportion of electricity structure considering the impact of transfers in and out, and carbon footprint factor weighting based on the proportion of electricity structure considering the impact of transfers in.

Furthermore, it calculates the electricity carbon footprint factor from two perspectives: users within the region and the power grid within the region, based on the principles of allocation and proportion. Based on actual needs, it selects the appropriate calculation method from the four calculation methods corresponding to the two perspectives and two principles, thereby solving the problem that the current calculation results of the electricity carbon footprint factor cannot accurately represent the distribution of the electricity carbon footprint within the region.

[0047] Example 1:

[0048] Embodiment 1 of this application provides a method for calculating the regional power grid carbon footprint factor, in order to solve the problem that the current calculation results of the power carbon footprint factor cannot accurately characterize the distribution of the power carbon footprint in the region.

[0049] The subject executing this method can be any computing device capable of implementing the method, such as a server, mobile phone, personal computer, smart wearable device, smart robot, etc.

[0050] Furthermore, the embodiments of this application do not limit the execution order of different steps. When using the method provided in the embodiments of this application, the execution order of different steps can be adjusted according to actual needs.

[0051] To clearly explain this plan, the following points will be made first:

[0052] This embodiment proposes a method for calculating the carbon footprint of regional power grids. The carbon footprint of electricity is characterized by the greenhouse gas emissions per kilowatt-hour of electricity consumed by a user over its entire lifecycle. The electricity lifecycle encompasses the generation and transmission / distribution stages. The generation stage includes equipment acquisition, construction, operation, maintenance, and decommissioning. The transmission / distribution stage includes grid construction, maintenance, and power losses during transmission. The following embodiments, based on the definition of the carbon footprint of electricity, compare mainstream domestic and international accounting systems and database modeling methods, and combine the power structure and electricity trading situation within the region to be calculated (e.g., within a province) to calculate the carbon footprint of electricity.

[0053] For ease of description, the following uses a regional power grid carbon footprint factor calculation device as the execution subject of this method to provide a detailed description of the method provided in this application embodiment.

[0054] like Figure 1 The diagram shown is a flowchart illustrating the specific implementation of a method for calculating the carbon footprint factor of a regional power grid according to an embodiment of this application, including the following steps 11-12:

[0055] Step 11: Obtain a baseline data system for calculating the electricity carbon footprint of the regional power grid.

[0056] In this embodiment, the region can be a geographical or administrative region where electricity carbon footprint accounting can be performed, such as a province, city, or a district or county within a province.

[0057] The benchmark data system includes benchmark data such as electricity consumption data and background carbon footprint factor data.

[0058] The electricity data includes at least the power generation and grid connection volume of each power type in the region, the electricity transferred into the region, the electricity transferred out of the region, the electricity consumption of users in the region, and the average line loss rate in the region; the background carbon footprint factor data includes the carbon footprint factor of each power type and the carbon footprint factor of power transmission and distribution.

[0059] Step 12: Based on the preset calculation method, select the data required by the calculation method from the benchmark data system and calculate the electricity carbon footprint factor.

[0060] Regarding specific accounting methods, this embodiment proposes four accounting methods based on two perspectives and two principles. The two perspectives are: the perspective of users within the region and the perspective of the power grid within the region; the two principles are: the allocation principle and the proportion principle.

[0061] The four accounting methods constructed include: carbon footprint allocation based on user electricity consumption within the region, carbon footprint allocation based on total user electricity consumption, carbon footprint factor weighting based on the proportion of electricity structure considering the impact of transfer in and out, and carbon footprint factor weighting based on the proportion of electricity structure considering the impact of transfer in.

[0062] In one feasible implementation, when calculating the electricity carbon footprint factor in a real area, one of four calculation methods can be selected. The four calculation methods can be used to calculate the corresponding carbon footprint factor respectively. The four carbon footprint factors calculated separately can be further processed (such as taking the average) to obtain the final regional electricity carbon footprint factor.

[0063] In another feasible implementation, based on the starting point of the accounting and the impact of inter-regional power allocation on the power generation structure, an accounting method suitable for the target scenario is selected from various accounting methods. Specifically, this could be:

[0064] The carbon footprint allocation method based on users' electricity consumption within a region is applicable to scenarios where carbon footprint is allocated from the user's perspective based on the actual electricity consumption of users within the region, and where the responsibility for the carbon footprint of the electricity consumption is not borne by users within the region.

[0065] The carbon footprint allocation method based on total user electricity consumption is applicable to scenarios where carbon footprint is allocated from the grid side to users within the region and users receiving electricity outside the region based on the total user electricity consumption of the regional grid.

[0066] The method of weighting the carbon footprint factor by considering the proportion of electricity structure affected by power transfers in and out is applicable to scenarios that connect with the international electricity carbon footprint accounting system and consider the impact of power transfers in and out between regional power grids on the actual electricity consumption structure of users.

[0067] The method of weighting the carbon footprint factor based on the proportion of electricity structure that takes into account the impact of power transfers is aligned with the international electricity carbon footprint accounting system. It considers the impact of power transfers on the regional power grid on the actual electricity consumption structure of users and is applicable to scenarios where cross-regional power transfers are the main source of electricity.

[0068] In one feasible implementation, if the calculation method is based on the allocation of carbon footprint according to the electricity consumption of users within the region, then the data required for the calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor. The model corresponding to this calculation method is as follows: Figure 2 As shown, from the perspective of users within the region, considering the cross-regional transfer of electricity, the carbon footprint is allocated based on the electricity consumption of users within the region. It should be noted that the electricity consumption of users within the region shown in the figure is directly obtainable statistical data. This statistical data is derived from the electricity generated and fed into the grid within the region, further based on the electricity transferred out, the electricity transferred in, and line losses.

[0069] Specifically, this includes steps 1211 to 1213:

[0070] Step 1211: Select electricity generation data and background carbon footprint factor data from the benchmark data system; the electricity generation data includes the power generation and grid connection volume of each type of electricity in the region. Electricity transferred into the region Electricity transferred out within the region Electricity consumption of users in the area The background carbon footprint factor data includes carbon footprint factors for each type of electricity. Carbon footprint factor of power transmission and distribution ;

[0071] Step 1212: Carbon footprint based on regional power generation and grid connection Carbon footprint of transferred electricity Carbon footprint of electricity consumption by users in the region The sum of these three minus the carbon footprint of the electricity transferred out It serves as the largest carbon footprint in the region.

[0072] Specifically, the carbon footprints of power generation and grid connection within the region, the carbon footprints of electricity transferred in, and the carbon footprints of electricity transferred out are all determined by multiplying the electricity data corresponding to each power type within the region with the corresponding carbon footprint factor; the carbon footprint of user electricity consumption within the region is determined by combining user electricity consumption within the region with the transmission and distribution carbon footprint factor. Specifically:

[0073] The carbon footprint of electricity generation and grid connection within the region Represented as:

[0074] = ;

[0075] in, The carbon footprint factor represents electricity type i, which includes at least wind power, solar power, hydropower, and thermal power. It should be noted that the carbon footprint factors for each electricity type in this embodiment temporarily use standardized carbon footprint factors from national or international databases.

[0076] Carbon footprint of transferred electricity Represented as: = ;

[0077] Check the carbon footprint of electricity consumption Represented as: = ;

[0078] Carbon footprint of electricity consumption by users in the region Represented as: = .

[0079] Step 1213: Use the ratio of the total first carbon footprint in the region to the electricity consumption of users in the region as the first electricity carbon footprint factor.

[0080] First carbon footprint factor The calculation formula can be expressed as:

[0081]

[0082] .

[0083] In one feasible implementation, if the carbon footprint allocation method is based on total user electricity consumption, then the data required for this calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor. The calculation model corresponding to this method is as follows: Figure 3As shown, from the perspective of the regional power grid, the calculation is based on the total electricity consumption of users within the region. The total users within the region include users receiving electricity from outside the region (users using electricity transferred out of the region) and users within the region. The calculation process specifically includes steps 1221 to 1223:

[0084] Step 1221: Select electricity generation data and background carbon footprint factor data from the benchmark data system; the electricity generation data includes the power generation and grid connection volume of each type of electricity in the region. Electricity transferred into the region Electricity transferred out within the region Electricity consumption of users in the area The background carbon footprint factor data includes carbon footprint factors for each type of electricity. Carbon footprint factor of power transmission and distribution ;

[0085] Step 1222: Carbon footprint based on regional power generation and grid connection Carbon footprint of transferred electricity Carbon footprint of electricity consumption by users in the region The sum of these three constitutes the second largest carbon footprint in the region.

[0086] Among them, the carbon footprint of power generation and grid connection within the region and the carbon footprint of power transfer are determined by multiplying the power data corresponding to each power type within the region with the carbon footprint factor of the corresponding power type; the carbon footprint of user power consumption within the region is determined by the user power consumption within the region and the transmission and distribution carbon footprint factor.

[0087] Step 1223: The ratio of the total second carbon footprint in the region to the total electricity consumption of users in the region is used as the second electricity carbon footprint factor; the total electricity consumption of users in the region is the sum of the electricity consumption of users in the region and the electricity transferred out of the region.

[0088] Second carbon footprint factor The calculation formula can be expressed as:

[0089] .

[0090] In one feasible implementation, if the calculation method involves weighting the carbon footprint factor based on the proportion of electricity volume that is considered influencing transfer in and out, then the data required for this calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor. The calculation model corresponding to this method is as follows: Figure 4 As shown, starting from the impact of the electricity consumption structure proportion of each type of electricity within the region, and using the weighted average of the electricity consumption structure proportion of each type of electricity within the region as the benchmark, while also considering the impact of various transfers in and out, the carbon footprint factor is calculated. The calculation process specifically includes steps 1231 to 1232:

[0091] Step 1231: Select electricity generation data and background carbon footprint factor data from the aforementioned benchmark data system; electricity generation data includes the power generation and grid connection volume of each power type. Electricity transferred into the region Electricity transferred out within the region Average line loss rate within the region The background carbon footprint factor data includes carbon footprint factors for each type of electricity. Carbon footprint factor of power transmission and distribution ;

[0092] Step 1232: Weight the carbon footprint factor of the corresponding power type according to the proportion of the first power structure of each power type, and sum the weighted sum with the transmission and distribution carbon footprint factor to obtain the first power structure weighted carbon footprint factor; take the first power structure weighted carbon footprint factor, add the first power structure weighted carbon footprint factor to the product of the first power structure weighted carbon footprint factor and the average line loss rate in the region, and obtain the third power carbon footprint factor.

[0093] Among them, the first electricity consumption structure proportion of the electricity type The first electricity consumption of the target power type within the region is determined by the ratio of the first electricity consumption of all power types within the region. The first electricity consumption of the target power type within the region is the generation and grid connection capacity of the target power type within the region. Electricity transferred in with the target power type within the region The sum minus the outflow of the target power type within the region The first electricity consumption for all power types within the region is the power generation and grid connection volume of each power type within the region. Electricity transferred into the region The sum minus the amount of electricity transferred out within the region .

[0094] The first electricity consumption structure percentage of the electricity type It can be represented as:

[0095] .

[0096] Third carbon footprint factor The calculation formula can be expressed as:

[0097] .

[0098] In one feasible implementation, if the calculation method involves weighting the carbon footprint factor based on the proportion of electricity volume structure considering the impact of transfers, then the data required for this calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor. The calculation model corresponding to this method is as follows: Figure 5As shown, starting from the impact of the electricity consumption structure proportion of each power type within the region, and using the weighted average of the electricity consumption structure proportion of each power type within the region as the benchmark, while also considering the impact of various transfers, the carbon footprint factor is calculated. The calculation process specifically includes steps 1241-1242:

[0099] Step 1241: Select electricity generation data and background carbon footprint factor data from the aforementioned benchmark data system; electricity generation data includes the power generation and grid connection volume of each type of electricity. Electricity transferred into the region Average line loss rate within the region The background carbon footprint factor data includes carbon footprint factors for each type of electricity. Carbon footprint factor of power transmission and distribution ;

[0100] Step 1242: Weight the carbon footprint factor of the corresponding power type according to the proportion of the second power structure of each power type, and sum the weighted sum with the transmission and distribution carbon footprint factor to obtain the second power structure weighted carbon footprint factor; add the second power structure weighted carbon footprint factor to the product of the second power structure weighted carbon footprint factor and the average line loss rate in the region to obtain the fourth power carbon footprint factor.

[0101] Among them, the second electricity consumption structure accounts for a certain percentage. The second electricity consumption of the target power type within the region is determined by the ratio of the second electricity consumption of all power types within the region; the second electricity consumption of the target power type within the region is the power generation and grid connection volume of the target power type within the region. Electricity transferred in with the target power type within the region The sum; the second electricity quantity of all power types within the region is the power generation and grid connection quantity of each power type within the region. Electricity transferred into the region The sum of.

[0102] The second electricity consumption structure percentage of electricity types It can be represented as:

[0103] .

[0104] Fourth carbon footprint factor The calculation formula can be expressed as:

[0105] .

[0106] The above describes the calculation of the regional power grid's carbon footprint factor. In practical applications, one of the four implementation methods given can be selected; the first, second, third, and fourth methods are used to distinguish the carbon footprint factors obtained under different calculation methods.

[0107] This application embodiment calculates the electricity carbon footprint by using benchmark data within the region, thus refining the granularity of the calculation. Furthermore, it calculates the electricity carbon footprint factor from two perspectives: users within the region and the power grid within the region, based on the principles of allocation and proportion. Based on actual needs, it selects the appropriate calculation method from the four calculation methods corresponding to the two perspectives and two principles, thereby solving the problem that the current calculation results of the electricity carbon footprint factor cannot accurately represent the distribution of the electricity carbon footprint within the region.

[0108] Example 2:

[0109] To address the problem that the calculation results of the electricity carbon footprint factor in the prior art cannot accurately represent the distribution of electricity carbon footprint in a region, this application also provides a calculation device for the electricity carbon footprint factor of a regional power grid, based on the same inventive concept as Embodiment 1.

[0110] A schematic diagram of the specific structure of the device is shown below. Figure 6 As shown, it includes the following functional units 61-62:

[0111] Data acquisition unit 61 is used to acquire a benchmark data system for calculating the electricity carbon footprint of the regional power grid;

[0112] The calculation unit 62, based on a preset calculation method, selects the data required by the calculation method from the benchmark data system and calculates the electricity carbon footprint factor;

[0113] The calculation methods include any one of the following: carbon footprint allocation based on user electricity consumption within the region, carbon footprint allocation based on total user electricity consumption, carbon footprint factor weighting based on the proportion of electricity structure considering the impact of transfers in and out, and carbon footprint factor weighting based on the proportion of electricity structure considering the impact of transfers in.

[0114] In one feasible implementation, if the calculation method is based on the allocation of carbon footprint according to the electricity consumption of users within a region, then the data required for the calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor; then the calculation unit is specifically used for:

[0115] Electricity data and background carbon footprint factor data are selected from the aforementioned benchmark data system; the electricity data includes the power generation and grid connection of each type of power in the region, the electricity transferred into the region, the electricity transferred out of the region, and the electricity consumption of users in the region; the background carbon footprint factor data includes the carbon footprint factor of each type of power and the carbon footprint factor of power transmission and distribution.

[0116] The first total carbon footprint of the region is calculated by subtracting the carbon footprint of outgoing electricity from the sum of the carbon footprints of power generation and grid connection within the region, the carbon footprints of incoming electricity, and the carbon footprints of electricity consumption by users within the region. The carbon footprints of power generation and grid connection, incoming electricity, and outgoing electricity within the region are all determined by multiplying the electricity data corresponding to each type of electricity within the region with the carbon footprint factor of the corresponding type of electricity. The carbon footprint of electricity consumption by users within the region is determined by the electricity consumption of users within the region and the carbon footprint factor of power transmission and distribution.

[0117] The ratio of the total first carbon footprint in the region to the electricity consumption of users in the region is used as the first electricity carbon footprint factor.

[0118] The types of electricity include at least wind power, solar power, thermal power, and hydropower.

[0119] In one feasible implementation, if the calculation method is based on the allocation of carbon footprint according to total user electricity consumption, then the data required for the calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor. The calculation unit is specifically used for:

[0120] Electricity data and background carbon footprint factor data are selected from the aforementioned benchmark data system; the electricity data includes the power generation and grid connection of each type of power in the region, the electricity transferred into the region, the electricity transferred out of the region, and the electricity consumption of users in the region; the background carbon footprint factor data includes the carbon footprint factor of each type of power and the carbon footprint factor of power transmission and distribution.

[0121] The carbon footprint of the region is the sum of the carbon footprint of the power generation and grid connection, the carbon footprint of the transferred power, and the carbon footprint of the user power consumption within the region; this is the second total carbon footprint within the region. The carbon footprint of the power generation and grid connection and the carbon footprint of the transferred power are determined by multiplying the power data corresponding to each power type within the region with the carbon footprint factor of the corresponding power type. The carbon footprint of the user power consumption within the region is determined by the user power consumption within the region and the transmission and distribution carbon footprint factor.

[0122] The ratio of the total second carbon footprint within the region to the total electricity consumption of users within the region is used as the second electricity carbon footprint factor; the total electricity consumption of users within the region is the sum of electricity consumption of users within the region and electricity transferred out of the region.

[0123] In one feasible implementation, if the calculation method is a weighted average of the electricity structure proportion considering the impact of transfers in and out on the carbon footprint factor, then the data required for the calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor. The calculation unit is specifically used for:

[0124] Electricity data and background carbon footprint factor data are selected from the aforementioned benchmark data system. Electricity data includes the power generation and grid connection of each power type, the electricity transferred into the region, the electricity transferred out of the region, and the average line loss rate within the region. Background carbon footprint factor data includes the carbon footprint factor of each power type and the carbon footprint factor of power transmission and distribution.

[0125] The carbon footprint factor of each power type is weighted by the proportion of the first power structure of each power type. The weighted sum is then summed with the carbon footprint factor of transmission and distribution to obtain the first power structure weighted carbon footprint factor. The first power structure weighted carbon footprint factor is then added to the product of the first power structure weighted carbon footprint factor and the average line loss rate in the region to obtain the third power carbon footprint factor.

[0126] The proportion of the first power volume structure of each power type is determined by the ratio of the first power volume of the target power type in the region to the first power volume of all power types in the region. The first power volume of the target power type in the region is the sum of the power generation and grid connection of the target power type in the region and the power transfer in the region minus the power transfer out of the target power type in the region. The first power volume of all power types in the region is the sum of the power generation and grid connection of each power type in the region and the power transfer in the region minus the power transfer out of the region.

[0127] In one feasible implementation, if the calculation method is a weighted average of the electricity structure proportion considering the impact of transfers on the carbon footprint factor, then the data required for the calculation method is selected from the benchmark data system to calculate the electricity carbon footprint factor. The calculation unit is specifically used for:

[0128] Electricity data and background carbon footprint factor data are selected from the aforementioned benchmark data system; the electricity data includes the power generation and grid connection of each power type, the power transferred into the region, and the average line loss rate in the region; the background carbon footprint factor data includes the carbon footprint factor of each power type and the carbon footprint factor of power transmission and distribution.

[0129] The carbon footprint factor of the corresponding power type is weighted by the proportion of the second power structure of each power type. The weighted sum is then summed with the carbon footprint factor of transmission and distribution to obtain the weighted carbon footprint factor of the second power structure. The second power structure weighted carbon footprint factor is then added to the product of the second power structure weighted carbon footprint factor and the average line loss rate in the region to obtain the fourth power carbon footprint factor.

[0130] The proportion of the second power volume structure of each power type is determined by the ratio of the second power volume of the target power type in the region to the second power volume of all power types in the region; the second power volume of the target power type in the region is the sum of the power generation and grid connection of the target power type in the region and the power transfer in the region; the second power volume of all power types in the region is the sum of the power generation and grid connection of each power type in the region and the power transfer in the region.

[0131] Based on the starting point of the accounting and the impact of power allocation between regions on the power structure, an accounting method suitable for the target scenario is selected from various accounting methods.

[0132] This application embodiment calculates the electricity carbon footprint by using benchmark data within the region, thus refining the granularity of the calculation. Furthermore, it calculates the electricity carbon footprint factor from two perspectives: users within the region and the power grid within the region, based on the principles of allocation and proportion. Based on actual needs, it selects the appropriate calculation method from the four calculation methods corresponding to the two perspectives and two principles, thereby solving the problem that the current calculation results of the electricity carbon footprint factor cannot accurately represent the distribution of the electricity carbon footprint within the region.

[0135] The processor 72, coupled to the memory 71, is used to execute the computer program stored in the memory 71 to perform a method for calculating the carbon footprint factor of a regional power grid as described in the foregoing embodiments.

[0136] When the processor 72 executes the computer program to perform the calculation method of regional power grid carbon footprint factor, it refines the calculation granularity by using benchmark data within the region to calculate the power carbon footprint. Furthermore, it calculates the power carbon footprint factor separately from the perspectives of electricity consumption by users within the region and electricity generation and grid connection by power sources within the region, based on the principles of allocation and proportion. This solves the problem that the current calculation results of power carbon footprint factor cannot accurately represent the distribution of power carbon footprint within the region.

[0137] When the processor 72 executes the computer program in the memory 71, in addition to the functions described above, it can also perform other functions, as detailed in the descriptions of the preceding embodiments.
