Description

Technical Field

[0001] The present invention relates to the field of power system planning, and in particular to a multi-region carbon emission pre-assessment method, system and medium. Background Art

[0002] The planning of future new power systems needs to comprehensively consider multiple factors such as safety, economy, and low carbon, and carbon emission analysis is often conducted in the form of carbon emission constraints. How to confirm the carbon emission constraint indicators for typical scenarios in key years in the future will have a huge impact on parameters such as the power structure, electricity proportion, and new energy consumption of the new power system.

[0003] Calculating interregional carbon transfers follows a clear sequence. Parameters such as the carbon emissions of the sending region and the regional power grid carbon emission factor must be determined before calculating carbon transfers. While some scholars have proposed methods for calculating carbon transfers between multiple regions, the relationship between sending and receiving ends between regions is often analyzed by drawing system structure diagrams and clearly annotating the power consumption and carbon emissions of each interconnecting line. When there are many regions and interconnecting lines, the analysis becomes complex, making it difficult to clearly and accurately calculate and analyze carbon emission transfers between regions. Furthermore, when complex scenarios such as green power and interconnecting lines exist within the transmission lines, using regional power grid carbon emission factors to calculate carbon emission transfers for other interconnecting lines can compromise the fairness of carbon emission accounting.

[0004] Existing models for carbon emission assessments of multi-regional power systems with interconnecting lines can calculate the CO2 emissions generated by local coal-fired and gas-fired power generation in each region. However, there is limited analysis of the carbon transfer effect of electricity transmission through interconnecting lines between regions. Existing inter-regional carbon emission transfer algorithms typically begin by mapping the system structure between each region and clarifying the corresponding relationship between the sending and receiving ends of each region. This becomes complex and difficult to calculate for scenarios with a large number of regions and a large proportion of electricity generated through interconnecting lines. Summary of the Invention

[0055] Example 1

[0056] Furthermore, in order to describe the specific process and purpose of the present invention in more detail, the above steps are described in more detail.

[0057] Specifically, the multi-region carbon emission pre-assessment method provided by the present invention includes the following steps:

[0058] Step S100: Obtain the regional calculation order based on the relationship between the sending end and the receiving end of the interconnection line.

[0059] Step S101: Sort by area serial number and analyze the corresponding relationship between the sending end and the receiving end of the i-th tie line.

[0060] Step S102: Determine whether the sending-end region sequence number is sorted before the receiving-end region sequence number. If not, swap the receiving-end region with the adjacent region on the left. Determine whether the sending-end region sequence number is sorted before the receiving-end region sequence number. If not, continue swapping with the adjacent region on the left. Continue swapping the sending-end region until it is before the receiving-end region. If so, skip this connection line and proceed to the next step.

[0061] Step S103: Analyze the corresponding relationship between the sending end and the receiving end of the (i+1)th tie line, and sort them according to the above steps S101 and S102.

[0062] Step S104: Analyze the influence of several tie lines one by one to form a sorting matrix that satisfies the relationship between the sending and receiving ends of all tie lines.

[0063] Step S200: Determine the initial power generation matrix, carbon emission matrix, and transferred power matrix of each region as the carbon emission, incoming and outgoing carbon emission conditions of the region.

[0064] Preferably, some areas can identify supporting power sources, while some areas cannot. In order to distinguish these supporting power sources, it is necessary to sort out the initial power generation matrix and carbon emission matrix of each area, the transfer power matrix of the interconnection lines with supporting power sources, and the carbon transfer matrix; the transfer power matrix without supporting power sources.

[0065] And get the following matrix:

[0066]

[0067] in, is the total power generation of local power sources in region m; is the total carbon emissions of local power sources in region m; The total power transmission capacity from area m1 to area m2 with a clear supporting power line. If there is no corresponding power line, the element value is 0. The total carbon emissions from area m1 to area m2 with a clear supporting power line. If there is no corresponding power line, the element value is 0; The total power transmission from area m1 to area m2 without a clear supporting power line. If there is no corresponding line, the element value is 0; is the total carbon emissions from area m1 to area m2 without a clear supporting power line, where the initial value of all elements is 0.

[0068] Step S300: Based on the regional calculation order and the local carbon emissions, incoming and outgoing carbon emissions of each region, the carbon emission factors of the outgoing electricity of each region are obtained one by one, and the net carbon emissions of each region are calculated according to the carbon emission factors.

[0069] like Figure 2 , Figure 3 As shown, regional power generation needs to consider local carbon emissions, incoming and outgoing carbon emissions, and the carbon emission factors of each region's outgoing electricity. Only then can local net carbon emissions be calculated. The specific steps include:

[0070] Step S301: Based on the relationship between regional input and output, determine the amount of carbon emissions received and the amount of carbon emissions delivered.

[0071] Step S302: Subtract the outgoing carbon emissions from the local carbon emissions and add the incoming carbon emissions to obtain the net carbon emissions of the region.

[0072] Step S303: Repeat the above steps for each region to obtain the net carbon emissions of each region.

[0073] Step S304: Generate a carbon emission matrix based on the net carbon emissions of each region.

[0074]

[0075] in, Represents the net emissions of region m.

[0076] Preferably, since some areas cannot determine the clear supporting power source, the carbon emissions received include the carbon emissions received from areas with clear supporting power sources and the carbon emissions received from areas without clear supporting power sources; similarly, the carbon emissions sent out also include the carbon emissions sent out from areas with clear supporting power sources and the carbon emissions sent out from areas without clear supporting power sources.

[0077] Bringing the above situation into step S300, the specific calculation process becomes:

[0078]

[0079]

[0080] in, is the total carbon emissions of local power sources in region m1; is the regional net carbon emissions of region m1; The total carbon emissions transferred from the interconnection line with clear supporting power supply to area m1; The total carbon emissions transferred by the interconnection line without a clear supporting power source received by area m1. According to the ranking, when calculating the power received by area m1, the carbon transfer amount sent by the sending end area corresponding to area m1 has been calculated previously; The total carbon emissions transferred by the interconnection line with clear supporting power supply for area m1; The total carbon emissions transferred by the interconnection line without a clear supporting power supply to area m1.

[0081]

[0082] according to Calculate the carbon emissions transferred in area m1 without supporting power interconnection lines.

[0083]

[0084] Repeat the above steps for each region to obtain the net carbon emissions of all regions.

[0085] Example 2

[0086] In order to verify the effect of the present invention, a specific scenario is now introduced for verification.

[0087] Step S100: Obtain the regional calculation order based on the relationship between the sending end and the receiving end of the interconnection line.

[0088] 1) Select multiple regions across the country for analysis. The names and IDs of each region are shown in Tables 1 and 2.

[0092] Contact line ID Receiver ID Receiver ID 1 1 2 2 1 3 3 1 4 4 5 1 5 3 3 6 6 2 7 5 2 8 4 2 9 6 3 10 5 3 11 6 5 12 7 1

[0093] 2) Sort the area IDs from left to right and from small to large, and analyze the corresponding relationship between the sending and receiving ends of the i-th (i=1) tie line;

[0094] Constructing the initial sorting matrix

[0095] S=[1,2,3,4,5,6,7]

[0096] 3) Determine whether the sending end ID is sorted before the receiving end ID. If so, proceed to step 4). If not, swap the receiving end region with the adjacent region on the left and determine whether the sending end ID is sorted before the receiving end ID. If not, continue swapping with the adjacent region on the left. Continue swapping the sending end region until it is sorted before the receiving end region, then proceed to step 4).

[0097] The first tie line corresponds to sending area 1 and sending area 2. The sorting S satisfies the requirement that the sending end ID is before the receiving end ID, and then proceed to step 4).

[0098] 4) Analyze the corresponding relationship between the sending end and the receiving end of the (i+1)th tie line, and adjust the sorting S according to step 3);

[0099] Analysis shows that the second and third tie lines have no effect on the sorting S. After the fourth tie line, the sorting S is adjusted:

[0100] S = [5, 1, 2, 3, 4, 6, 7];

[0101] After the 4th tie line, adjust the sorting S:

[0102] S = [5, 1, 3, 2, 4, 6, 7];

[0103] Carry out sorting adjustments in sequence

[0104] 5) Analyze the impact of n tie lines one by one and form a sorting matrix that satisfies the sending and receiving end relationships of all tie lines.

[0105] After analyzing the 12 curves, the final sorting matrix S = [6, 7, 4, 1, 3, 5, 2] is formed.

[0106] Step S200: Determine the initial power generation matrix, carbon emission matrix, and transferred power matrix of each region as the carbon emission, incoming and outgoing carbon emission conditions of the region.

[0107] Sort out the initial power generation matrix and carbon emission matrix of each region, the transfer power matrix and carbon transfer matrix of the interconnection lines with supporting power sources; and the transfer power matrix without supporting power sources.

Specifically, it includes a first relationship corresponding component, which can sort according to the regional sequence number and analyze the corresponding relationship between the sending and receiving ends of the i-th tie line; a bubble sorting component, which can determine whether the sending end region sequence number is sorted before the receiving end region sequence number. If not, it will swap the receiving end region with the adjacent region on the left, and determine whether the sending end region sequence number is sorted before the receiving end region sequence number. If not, it will continue to swap with the adjacent region on the left; the sending end region will be swapped before the receiving end region; if so, the tie line will be skipped and the next step will be carried out; the second relationship corresponding component can analyze the corresponding relationship between the sending and receiving ends of the i+1th tie line and sort according to the above steps; The matrix generation component can analyze the impact of several tie lines one by one and form a sorting matrix that satisfies the relationship between the sending and receiving ends of all tie lines; The data collection module determines the initial power generation matrix, carbon emission matrix, and transfer power matrix of each region as the carbon emission, incoming and outgoing carbon emission information of the region; The net emission calculation module can determine the carbon emissions received and the carbon emissions sent out based on the relationship between regional input and output; the local carbon emissions are subtracted from the sent carbon emissions and added to the received carbon emissions to obtain the net carbon emissions of the region; the above steps are repeated for each region to obtain the net carbon emissions of each region.
