Description

Technical Field

[0001] This invention relates to a dynamic electric carbon factor calculation method based on time-domain trend and regional heterogeneity correction, belonging to the field of novel power system carbon metering. Background Technology

[0002] The power system is currently undergoing a profound transformation from a traditional binary balance of "safety-economy" to a ternary synergy of "safety-economy-low carbon". As a fundamental measure of carbon emission responsibility on the electricity consumption side, the accuracy of the electricity carbon dioxide emission factor directly affects the verification of product carbon footprint and the implementation of the dual carbon control system.

[0003] However, existing electricity carbon factor accounting systems still face significant technical bottlenecks in practical applications. Firstly, the spatiotemporal characteristics are ambiguous: current mainstream accounting methods mostly use annual or regional grid average factors, which are "static retrospective" calculations. Under the new power system, renewable energy output fluctuates dramatically, and annual average factors cannot reflect the strong time-varying characteristics of electricity production with seasonal and temporal variations, leading to severe distortion in the allocation of carbon emission responsibility at the electricity consumption end in the time domain. Secondly, regional heterogeneity is ignored: existing administrative division accounting often ignores the heterogeneity of regional resource endowments, economic structures (such as the proportion of secondary industry), and social statistical parameters (such as population and output). Since direct emission sources and indirect responsibility points are geographically separated, and the above methods fail to effectively decouple the responsibility relationship between them, there is a lack of a universal "electricity-carbon coupling" evaluation model to decouple direct emission sources and indirect responsibility points, resulting in unequal carbon reduction incentives between resource-rich areas and load centers. Furthermore, with the popularization of green electricity and green certificate trading, the impact of market trading behavior on carbon emission accounting is becoming increasingly prominent. If the accounting method does not take market transactions into account, the problem of "double accounting for the environmental attributes" of electricity is very likely to occur. The existing "top-down" method is difficult to accurately separate trading trends from natural trends, and cannot form a closed-loop carbon traceability logic.

[0004] Therefore, developing a dynamic carbon factor accounting method that can capture time-domain fluctuation trends in real time and perform multiple corrections based on regional heterogeneity characteristics (such as output value, population, and industrial structure) has important engineering value for building an accurate and transparent carbon metering system. Summary of the Invention

[0059] Example 1: As Figures 1-2 As shown, according to a first aspect of the present invention, a method for calculating dynamic electrocarbon factor based on time-domain trend and regional heterogeneity correction is provided, comprising:

[0060] S1. Taking the composite region as the research object, a time-domain trend correction model is constructed under the current statistical period to obtain the time-domain trend correction coefficient. The composite region includes multiple power supply zones (in a new power system, a composite region refers to a unified accounting unit formed by merging multiple geographically adjacent power supply zones with close power supply relationships).

For example: in years, if the current statistical period... If it is 2026, then it represents the year 2026. Represents 2025; for each statistical period, measured in months, then... The total power generation is determined by the power generation structure of the complex area, and generally may involve hydropower, thermal power, wind power, solar power, energy storage, etc.

This leads to a decrease, thereby driving the total electrocarbon factor EF. s,t Shift towards low-carbonization.

[0091] Furthermore, S3 specifically refers to:

[0092] Based on the hyperbolic tangent function, construct a smooth response function;

[0093] After processing the thermal power deviation, green power deviation, inter-regional input adjustment, and secondary industry share through a smoothing response function, a regional heterogeneity correction coefficient is synthesized according to the weighted superposition rule.

[0097] Furthermore, in order to ensure the dynamic electrocarbon factor The numerical stationarity of the above deviations is assessed using a smooth response function constructed based on the hyperbolic tangent (tanh). Perform nonlinear fitting:

[0099] Where x represents the proportion of thermal power deviation, green power deviation, inter-regional input adjustment, or secondary industry (when...). At that time, it represents the deviation of thermal power. ,when At that time, it represents the cross-regional input adjustment amount. ,when At that time, it represented the proportion of the secondary industry. ,when At that time, it represents the deviation of green electricity. ), For the first An adjustment coefficient is used to control the slope of the function graph, i.e. the response sensitivity and the marginal contribution of each deviation to the final factor. For the first An offset is used to control the response activation threshold point for accounting.

[0100] To verify the accuracy of the proposed carbon factor calculation, this invention sets up three typical scenarios, selecting a provincial power grid as the composite region, and conducting a 12-month (monthly) comparative calculation of three typical simulated zones under the jurisdiction of the provincial power grid. The specific parameter settings are shown in Table 1:

[0101] Zone A (Region A): The electricity consumption of the secondary industry accounts for more than 75%, the local thermal power capacity is insufficient, and it is heavily dependent on external power sources.

[0102] Zone B (Region B): The industrial structure is balanced, and the proportion of new energy is on par with the provincial average.

[0103] Zone C (Region C): Rich in wind and solar resources, with a large surplus of green electricity, it undertakes the main peak-shaving and power transmission tasks for the entire province.

[0104] Table 1

[0105]

[0106] The correction formula proposed in this invention The calculations were performed, and the results for partition A are shown in Table 2 below (using the traditional static method). Electric carbon factor considering time-domain correction ):

[0107] Table 2

[0108]

[0109] The simulation results in Table 2 demonstrate that, in terms of high-frequency capture capability, this invention successfully captures fluctuations of over 30% in the overall grid's carbon factor caused by seasonal renewable energy consumption, effectively solving the data lag problem of traditional static factors. Regarding spatial premium, the difference in carbon factor between partition A and partition C at the same time can reach over 100% through regional correction, accurately reflecting the fairness principle of "whoever uses thermal power is responsible, and whoever generates green power benefits." In terms of algorithm stability, after introducing the tanh smoothing response function, even under extreme power conditions in partition A, the calculated factor can still converge stably within the physical upper limit, proving its robustness.

[0110] Furthermore, simulation results for the statistical period 2025 are presented as follows: Figure 2 As shown, through Figure 2It is evident that the accounting method proposed in this invention possesses significant technological advantages: First, this method successfully overcomes the "time lag" defect of traditional accounting methods in the time dimension. Compared to the black dashed line (0.5839) representing the annual static baseline in the figure, the dynamic carbon factor generated by the method of this invention for each region can accurately capture the seasonal fluctuations of the power system's power source composition, truly restoring the emission characteristics during peak summer demand and periods of high renewable energy generation. Second, by introducing regional heterogeneity correction, this method achieves a significant distinction between the accounting results of region A (high-energy-consuming industrial type) and region C (green energy-rich type), accurately quantifying the carbon emission responsibility of different regions and reflecting the fairness and scientific nature of the accounting logic. Furthermore, this method innovatively adopts a hyperbolic tangent (tanh) smoothing response function, ensuring that the curves of each scenario always maintain nonlinear smooth evolution when facing data fluctuations, effectively avoiding step-like abrupt changes caused by extreme data, and the algorithm possesses robustness.
