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 future key years will have a huge impact on parameters such as the power structure, electricity proportion, and new energy consumption of the new power system.

[0003] There is a clear order in the calculation of inter-regional carbon transfer. It is necessary to first solve the carbon emissions of the sending area, the regional power grid carbon emission factor and other parameters before the carbon transfer can be calculated clearly. Some scholars have proposed a method for calculating carbon transfer between multiple regions, but the relationship between the sending and receiving ends of each region is often analyzed by drawing a system structure diagram and clearly marking the power and carbon emissions of each interconnection line. When the number of regions and interconnection lines is large, the analysis scenario becomes complicated, and it is difficult to clearly and accurately calculate and analyze the carbon emission transfer between regions. At the same time, when there are complex scenarios such as green electricity and interconnection line supporting power grids in the transmission line, using the regional power grid carbon emission factor to calculate the carbon emission transfer of other interconnection lines will affect the fairness of carbon emission accounting.

[0004] For the existing technology of carbon emission assessment and calculation for multi-regional power systems with interconnection lines, there are existing calculation models that can calculate the CO2 emissions generated by local coal-fired power and gas-fired power in each region, but there is less analysis on the carbon transfer effect brought by the transmission of electricity through interconnection lines between multiple regions. The existing inter-regional carbon emission transfer algorithm generally draws the system structure diagram between each region first, and sorts out the corresponding relationship between the sending end and the receiving end between each region. This will become complicated and difficult to calculate for scenarios with many regions and a large proportion of interconnection line electricity. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a multi-region carbon emission pre-assessment method and system, which can automatically sort out the relationship between the sending and receiving ends of each region, and calculate the net carbon emissions of the regional power grid after considering the carbon transfer of the interconnection line in each region, and at the same time propose an improved residual carbon emission factor calculation method based on the carbon emission characteristics of the interconnection line.

[0055] Embodiment 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 comprises the following steps:

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

[0059] Step S101, sorting according to the area serial number, and analyzing the corresponding relationship between the sending end and the receiving end of the i-th connecting line.

[0060] Step S102, determine whether the sequence number of the sending end area is sorted before the sequence number of the receiving end area. If not, exchange the receiving end area with the adjacent area on the left, and determine whether the sequence number of the sending end area is sorted before the sequence number of the receiving end area. If not, continue to exchange with the adjacent area on the left; keep exchanging the sending end area before the receiving end area; if so, skip this connection line and proceed to the next step.

[0061] Step S103, analyzing the correspondence between the sending end and the receiving end of the (i+1)th tie line, and sorting them according to the above steps S101 and S102.

[0062] Step S104, analyzing the influence of several tie lines one by one, and forming 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 transfer 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 area m; is the total carbon emissions of local power sources in region m; It is the total power transmission from area m1 to area m2 with a clear supporting power line. If there is no corresponding line, the element value is 0; It is the total carbon emissions from area m1 to area m2 with a clear supporting power line. If there is no corresponding line, the element value is 0; It is the total power transmission from area m1 to area m2 without a clear supporting power connection line. If there is no corresponding connection line, the element value is 0; It 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, obtain the carbon emission factor of the outgoing electricity of each region one by one, and calculate the net carbon emissions of each region according to the carbon emission factor.

[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 the electricity delivered to each region one by one. Only then can the local net carbon emissions be calculated. Specifically, the following steps are included:

[0070] Step S301: Determine the carbon emissions received and the carbon emissions sent based on the regional input and output relationship.

[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 area.

[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 emission of region m1; The total carbon emissions transferred for the interconnection lines with clear supporting power sources received by area m1; The total carbon emissions transferred by the interconnection line without clear supporting power supply 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 before; The total carbon emissions transferred by the interconnection line with clear supporting power supply sent to area m1; The total carbon emissions transferred by the interconnection line without clear supporting power supply sent to area m1.

[0081]

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

[0083]

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

[0085] Embodiment 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 according to the relationship between the sending end and the receiving end of the interconnection line.

[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) According to the regional IDs, sort them from left to right and from small to large, and analyze the corresponding relationship between the sending end and the receiving end 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 sender ID is sorted before the receiver ID. If so, proceed to step 4); if not, swap the receiver region with the left adjacent region to determine whether the sender ID is sorted before the receiver ID. If still not, continue to swap with the left adjacent region; keep swapping the sender region until it is before the receiver region, and then proceed to step 4);

[0097] The corresponding relationship of the first tie line is sending end area 1 and sending end area 2. The sorting S satisfies the requirement that the sending end ID is before the receiving end ID, and step 4 is performed;

[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 order S:

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

[0103] Carry out sorting adjustment in sequence

[0104] 5) Analyze the impact of n tie lines one by one and form a sorting matrix that satisfies the relationship between the sending and receiving ends 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 transfer 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 of the interconnection lines with supporting power sources, and the carbon transfer matrix; the transfer power matrix without supporting power sources.
