Abstract
Description
Technical Field
[0001] This application relates to the technical field of determining carbon emissions from power transmission, and in particular to a method, apparatus, and equipment for determining the sources and intensity of carbon emissions from power transmission. Background Technology
[0002] With the continuous advancement of electricity market trading and the ongoing expansion of regional power transmission, the carbon footprint accounting of electricity consumption is gradually evolving from simple average calculations to a more refined accounting model that is traceable, reconcilable, and auditable. Accurate and reliable attribution results for electricity carbon emissions are not only an important basis for corporate carbon disclosure and green electricity certification, but also a crucial support for regional emission reduction effectiveness assessment and policy formulation.
[0003] In existing technologies, electricity consumption on the demand side is typically calculated based on market-traded and settled electricity volume, while the supply side directly uses regional "power generation" statistics for matching. Due to systemic differences between power generation and the electricity available for external supply, such as differences in plant usage, self-consumption, statistical boundaries, and metering methods, direct matching can easily lead to incomparability between the supply and delivery sides, resulting in biased carbon emission attribution results.
[0004] In cross-regional power transmission scenarios, existing technologies mostly use net inflow / outflow of electricity or net exchange between regions for processing. It is difficult to distinguish the specific cross-regional channels through which the electricity actually passes, and it is also impossible to establish consistency constraints between the electricity decomposition results and the exchanged electricity at the channel level, resulting in a lack of traceable evidence to support the source path.
[0005] In addition, the breakdown of the power supply structure of external power is usually allocated according to the overall power supply structure ratio of the source region, which fails to reflect business evidence such as the power transmission contract structure, power transmission plan structure, or power supply structure of the channel, thus affecting the interpretability of the accounting results and the audit pass rate.
[0006] At the same time, if the impact of comprehensive line loss in power transmission and distribution is ignored under the delivery side boundary, or if the carbon emissions of power transmission and distribution assets are not reasonably allocated over time, it will also lead to problems such as unclear result boundaries, difficulty in reconciliation, and incomparability between years.
[0007] Therefore, there is an urgent need for a method based on regional power transmission that can trace the source of electricity and determine carbon emission intensity. Summary of the Invention

[0057] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

Figure 1In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or placed in the cloud or on other network servers.

Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart vehicle devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. Server 104 can be implemented using a standalone server or a server cluster composed of multiple servers.
[0059] In one exemplary embodiment, such as Figure 2 As shown, a method for determining the sources and intensity of carbon emissions from electricity transmission is provided, and this method is applied to... Figure 1 Taking a computer device as an example, the explanation includes the following steps S201 to S204. Wherein:
[0060] S201 obtains the exchange power, power consumption, and line loss rate in the target area.
[0061] The target area refers to a specific geographical or administrative region where electricity consumption occurs. This area contains one or more electricity-consuming entities (such as businesses, industrial parks, and electricity customers), and their electricity consumption can be independently measured and accounted for. External power supply refers to the electricity input into the electricity-consuming area from outside the area. This electricity is typically obtained through inter-regional power transmission (such as grid interconnection) to meet the electricity demand within the electricity-consuming area. The line loss rate characterizes the energy loss rate between power generation equipment and power-consuming equipment within the target area.
[0062] S202 determines the power supply within the target area based on power consumption and line loss rate.
[0063] In some embodiments, this embodiment can also directly obtain the line loss rate in the target area. (Satisfies 0≤L<1).
[0064] In this embodiment, the power supply can also be calculated from the power consumption: , of which 1- This represents the proportion of electricity supplied after deducting line losses, i.e., the actual electricity consumption; and it also gives the electricity consumption corresponding to line losses. If the line loss rate is missing or abnormal, take the value according to the preset replacement rule and record it, or output a non - calculable mark.
[0065] S203 determines the power supply ratio of at least one power supply source in the target area according to the exchanged power and the supplied power.
[0066] Among them, the power supply source is used to characterize the source of power carbon emissions in the target area.
[0067] In some embodiments, the exchanged power is used as a constraint condition, and the supplied power is split under at least one power supply source to obtain the power supply ratio of at least one power supply source in the target area.
[0068] In some embodiments, obtain the power consumption of the target area ; Determine the settlement attribution area of the target object according to the transaction settlement attribution rule (such as settlement account number attribution, settlement unit attribution, electricity sales company settlement attribution, etc.), denoted as: ; Use r0 as the unified bearing area of the power delivery boundary of the target object and the subsequent source attribution to ensure that the subsequent calculation results are consistent with the settlement reconciliation caliber. Obtain the power generation data of different power source types at the regional level, complete the mapping of caliber and type, and form a supply - side basic data set. Obtain the power generation of different power generation types k in each area r ∈ R in the period p: ; Map the power source type (map the type calibers of different data sources to the unified K), perform consistency processing on the power generation unit, time boundary, and statistical caliber (such as monthly natural month, annual natural year, or settlement month, etc.), and mark the missing values and abnormal values.
[0069] In some embodiments, introduce the "conversion coefficient from power generation to available power" at the regional level to convert the statistical power generation into available power closer to the settlement delivery caliber, so as to reduce the systematic deviation between the power generation statistical caliber and the settlement caliber. Construct a reference power for each area r (t is the historical period), and the reference power should preferably adopt a caliber consistent with the settlement delivery or confirmed for reconciliation (such as the summary of regional settlement delivery power, the summary of regional electricity sales settlement, etc.). Based on historical data as the training window (such as the last 12 months or the last 3 years), use robust estimation or regression methods to推算 the conversion coefficient. In the embodiment, the weighted ratio method can be used: ; Among them is the weight (higher weight can be assigned to recent samples, and the weight of abnormal months can be reduced). If the training fails or key data is missing, the ( <p) of the most recent valid period can be used according to the preset fallback rule, and the reason for fallback is recorded. Convert the statistical power generation into regional - classified available power: And obtain the total available local power in the region: .
[0070] It should be noted that this embodiment can also determine the power type structure weight for each channel c:a→b. The priority of evidence can be: channel supporting structure > contract structure > planning structure > inter-regional structure > overall structure of the source region (lowest priority). To ensure the weights satisfy normalization: If the conditions are not met, the data will be normalized according to the rules or marked as abnormal and recorded. Based on weights, the channel exchange power will be divided into channel power for different power types: This ensures that the hard constraints on the channel are met.
[0071] S204 determines carbon emission intensity based on electricity consumption and the proportion of electricity supplied by at least one power source.
[0072] Carbon emission intensity includes carbon emission intensity on the power supply side and carbon emission intensity on the power consumption side.
[0073] In some embodiments, the carbon emission intensity on the power supply side within the target area is determined based on the electricity consumption and the power supply ratio of at least one power source; the carbon emission intensity on the electricity consumption side within the target area is determined based on the carbon emission intensity on the power supply side and the electricity supply.
[0074] In the above embodiments, by using the actual electricity consumption on the power consumption side as the accounting basis and combining it with line loss conversion, the electricity caliber of the supply side and the delivery side is unified, which significantly improves the accuracy and annual comparability of carbon emission intensity accounting. At the same time, by using the electricity exchanged across regions as a hard constraint, a traceable chain of electricity source and transmission path is established, ensuring that the decomposition results are strictly consistent with the channel metering data, which greatly enhances the verifiability and audit credibility of carbon emission source attribution. In addition, in the decomposition of external power structure, business basis such as the channel matching power structure is given priority, so that the accounting results are more in line with the actual power transmission composition. The time allocation of carbon emissions from transmission and distribution assets is comprehensively considered, and finally a clear boundary, reconcilable and recalcible carbon emission intensity on the delivery side is formed, which provides reliable technical support for regional carbon management, green power certification and regulatory disclosure.
[0075] It should be noted that this embodiment can also obtain multi-source exchange power data for each cross-regional channel c (which may include fields such as sending-end region a, receiving-end region b, direction, and period p), for example, the settlement caliber. Measurement caliber Dispatch criteria The main power volume of the settlement channel is determined according to the "settlement caliber priority" principle: Record the source fields of the data used for reconciliation and verification. Treat the channel exchange volume as a hard constraint: when decomposing external power attribution, at the channel level, it must satisfy the condition that "the sum of the decomposed volumes equals the channel exchange volume," meaning for each channel: ;in This is the result of splitting the channel power by power type.
[0076] It should be noted that this embodiment can also use the cross-regional channel dimension as the main traceability index to store the sending-end region a, receiving-end region b, cycle p, and main caliber power of channel c. Information such as source of incoming power and verification status is included. In subsequent output of incoming power breakdown and object attribution, the mapping relationship of "source region—channel—receiving end region—object" is retained, ensuring that the source of incoming power for any object can be traced back to the specific channel and corresponding exchange power record, thus meeting the audit's verification requirements for "path and quantity consistency".
[0077] Figure 3 This is a flowchart illustrating the steps for determining the carbon emission intensity on the power supply side in one embodiment. This embodiment refines the steps in the above embodiment for determining the carbon emission intensity on the power supply side within a target area based on electricity consumption and the power supply ratio of at least one power source. This embodiment provides an optional method for determining the carbon emission intensity on the power supply side, including the following steps:
[0078] S301 obtains the power supply side factor of at least one power supply type.
[0079] Among them, the power supply side factor is used to characterize the carbon emissions generated by producing a unit of electricity for the corresponding power supply type.
[0080] S302 determines the carbon emission intensity on the power supply side within the target area based on electricity consumption, the power supply ratio of at least one power source, and the power supply side factor.
[0081] In some embodiments, this embodiment can inherit the settlement origination structure of the target object and settle the electricity amount of the object. Decomposed into attributable charge: .
[0082] Furthermore, obtain a database of carbon footprint factors on the power generation side. (Available by region and power type), determine the power supply-side carbon intensity within the target region based on attributable electricity, the proportion of power supplied from at least one power source, and the power supply-side factor:
[0083]
[0084] in, For the power supply side factor, To attribute the electricity, The proportion of power supplied from at least one power source.
[0085] In the above embodiments, by introducing power supply side factors based on power supply type and combining electricity consumption and the power supply ratio of each power source, the carbon emission contribution of different power supply types (such as coal power, hydropower, wind power, etc.) in the power supply structure can be accurately quantified, realizing a refined accounting of carbon emission intensity on the power supply side. This method not only reflects the actual impact of power supply structure differences on carbon emissions and avoids the distortion problem caused by simple average accounting, but also makes the composition of carbon emission sources more transparent and interpretable, providing scientific and reliable data support for the formulation of regional carbon emission reduction strategies, optimization of green power structure, and carbon emission performance evaluation.
[0086] Figure 4 This is a flowchart illustrating the steps for determining the carbon emission intensity on the electricity consumption side in one embodiment. This embodiment refines the steps for determining the carbon emission intensity on the electricity consumption side within a target area based on the carbon emission intensity on the power supply side and the amount of electricity supplied, as described in the previous embodiment, and includes the following steps:
[0087] S401 obtains the carbon emissions of power transmission and distribution equipment within a target area during a preset period.
[0088] S402 determines the carbon emission allocation within the target area based on the carbon emissions of power transmission and distribution equipment within a preset period.
[0089] In some embodiments, let the set of power transmission and distribution equipment be A. For power transmission and distribution equipment code∈A, obtain its full life cycle carbon footprint or implicit emissions TotalEmis(code) and service life Y(code). If the accounting period is monthly, let Np=12; if it is annual, then Np=1.
[0090] The asset's allocated emissions over period p are as follows: Carbon emissions are allocated based on the settlement region: .
[0091] Obtain the denominator for regional delivery electricity volume with a caliber consistent with transaction settlement. (e.g., total electricity delivered for regional settlement), determine the carbon emission allocation for the target region: .
[0092] S403 determines the carbon emission intensity on the electricity consumption side within the target area based on the carbon emission intensity on the power supply side, electricity consumption, and carbon-allocated emissions.
[0093] In some embodiments, when it is necessary to output a comprehensive factor on the delivery side, this embodiment determines the carbon emission intensity on the electricity consumption side within the target area based on the carbon emission intensity on the power supply side, the amount of electricity supplied, and the carbon-allocated emission amount:
[0094]
[0095] in, Carbon emission intensity on the electricity consumption side, Carbon emission intensity on the power supply side, Carbon-allocated emissions. This represents electricity consumption.
[0096] It should be noted that this embodiment can also input data for archiving, that is, retain the settlement electricity consumption of the target object. Settlement Region The mapping basis; regional classification of power generation Sources and versions; cross-regional power exchange The original data, the ruling results (with settlement criteria taking priority), and the verification records; line loss rate Sources include: fields required for asset ledgers and allocation. Key intermediate results are archived, i.e., retention conversion factors. The calculation record (training window, method, parameters, rollback status), i.e., channel split weights. Evidence citation and normalization verification; regional source weighting Attributable power of objects ; and detailed calculations of line loss offsetting and asset allocation. Recalculated output package: Generates a result package containing "data version number / timestamp / caliber description / anomaly and substitution markers", ensuring that under the same input and parameter conditions, one-click recalculation can be performed and consistent results can be obtained to meet audit, regulatory disclosure and reconciliation requirements.
[0097] In the above embodiments, by introducing the carbon emissions of power transmission and distribution equipment within a preset period and reasonably allocating them to the electricity consumption side, the quantitative inclusion of carbon emissions in the power transmission and distribution process is achieved, making the accounting boundary of the carbon emission intensity on the electricity consumption side more complete and scientific. This method effectively distinguishes the carbon emission responsibilities of the generation side and the power transmission and distribution network, avoiding the deviation caused by simply attributing power transmission and distribution emissions to the generation side or ignoring them, and significantly improving the accuracy and regional comparability of the accounting results. At the same time, using the power supply as the denominator for allocation ensures consistency with the delivery caliber, making the final carbon emission intensity on the electricity consumption side clear and reconcilable, and truly reflecting the actual carbon emission level borne by the user side, providing solid technical support for precise policy implementation, low-carbon assessment, and evaluation of the grid emission reduction effectiveness.
