Description

Technical Field

[0001] This invention belongs to the field of power system data management and green energy accounting technology, specifically involving a provincial and municipal level non-fossil energy electricity consumption accounting method based on the energy consumption side. It can accurately count and calculate the non-fossil energy electricity consumption within provincial and municipal administrative regions based on the energy consumption side, providing systematic and reliable technical support for government energy conservation assessment, renewable energy responsibility weight calculation, and non-fossil energy consumption accounting. It is applicable to provincial and municipal level non-fossil energy electricity consumption accounting scenarios under the national unified electricity market and green certificate trading system. Background Technology

[0002] Against the backdrop of energy structure transformation driven by the "dual carbon" goals, accurate and fair accounting of non-fossil energy electricity consumption in various provinces and cities has become a key requirement. With the rapid development of green electricity and green certificate trading, the existing accounting system is unable to accurately calculate the current status of non-fossil energy consumption from the actual consumption side of users, and has some technical shortcomings.

[0003] The existing statistics on non-fossil energy consumption mainly adopt two methods: one is production-side statistics based on physical electricity volume, following the principle of "whoever generates electricity, counts it." Although this method is convenient for data acquisition, it is easy to overlook the actual consumption situation on the regional consumption side, leading to accounting errors; the other is statistics based on physical power flow analysis. This method has high technical cost requirements, is difficult to implement, and is highly dependent on the construction and improvement of a unified national platform.

[0004] With the national energy transition and the transformation of assessment methods, in order to accurately "control fossil energy consumption and incentivize the development of non-fossil energy," the consumption of non-fossil energy is deducted from fossil energy consumption. However, there are currently some accounting problems, specifically: The lack of standardized statistical accounting methods leads to significant issues of double counting and accounting discrepancies: Green certificates and physical electricity consumption may be traded to different provinces, and the existing statistical system cannot effectively coordinate the data flow of these two different attributes. Furthermore, the lack of standardized formats for electricity contracts and settlement vouchers significantly increases the time and manpower costs of statistical accounting, making it difficult to guarantee accuracy and prone to double counting or omissions.

[0005] The disconnect between green certificate trading and physical electricity consumption leads to a confused accounting logic: Green certificates, as trading instruments independent of physical electricity consumption, can circulate in the national market. This can result in situations where province A purchases green certificates corresponding to a much larger amount of electricity than the actual electricity traded between the two provinces. This causes non-fossil energy consumption to fluctuate arbitrarily between provinces that previously had no electricity exchange, severely undermining the physical foundation and fairness of the accounting system.

[0006] Insufficient accuracy in consumption-side accounting: Existing calculation methods are mostly based on production-side or physical flow statistics, which cannot accurately reflect actual consumption on the consumption side. For green electricity through centralized bidding, the source of the electricity cannot be clearly identified, posing a traceability problem. It is impossible to directly distinguish the green electricity purchased by market entities, and it is also difficult to determine the final destination and specific users of the green electricity.

[0007] The provincial and municipal accounting systems are not coordinated: the provincial accounting results are difficult to effectively decompose to the municipal level, while the municipal data on distributed energy and self-generated and self-consumed electricity have not been effectively integrated into the provincial accounting, resulting in discrepancies between the provincial and municipal accounting results and the inability to form a unified and coherent accounting system.

[0008] In summary, there is an urgent need in this field for a technical solution that starts from the energy consumption side, can effectively coordinate physical electricity consumption and green certificate data, solve problems such as double counting, confusing accounting logic, and inconsistencies between provincial and local accounting, and achieve accurate, efficient, and fair non-fossil energy electricity consumption accounting. Summary of the Invention

[0009] (a) Technical problems to be solved This invention aims to solve the following technical problems existing in current non-fossil energy electricity consumption accounting technology, specifically as follows: 1. Insufficient user traceability leads to a distortion of the current consumption situation.

[0010] The existing accounting system uses the electricity generated and fed into the grid on the power generation side for macro-level statistics, which cannot accurately trace non-fossil energy electricity to specific users, time, and spatial dimensions on the end-consumer side. This model has data gaps between "green electricity production" and "green electricity consumption," making it difficult to support refined management and credible consumption certification.

[0011] 2. The user classification model is too general, and the attribution of consumer responsibility is unclear.

[0012] Existing consumer-side accounting methods for classifying end-users are rather crude and fail to define consumption responsibilities based on users' actual participation patterns in the electricity market. This invention provides a precise classification based on users' actual participation patterns in the electricity market, such as direct market transactions, grid-mediated power purchases, and self-consumption, thus fairly defining the green consumption responsibilities and contributions of different market participants.

[0013] 3. The accounting at the provincial and local levels is disconnected, and the data cannot be verified in a closed loop.

[0014] The present invention proposes two sets of non-fossil energy accounting models based on user consumption at the provincial and municipal levels. The provincial accounting model (such as one based on the production side or the whole network balance) and the municipal accounting model (such as one based on the consumption side classification) are unified and connected in terms of statistical scope, coverage and data sources.

[0015] 4. Lack of fair allocation rules for untraceable green electricity For green electricity purchased and distributed through agents by power grid companies, as well as green electricity consumption that is difficult to measure directly, such as distributed self-generation and self-consumption, existing technologies lack a unified, transparent, and auditable mechanism for the allocation of green certificates or environmental rights. This invention specifically proposes allocation rules for such green electricity, filling a gap in this field.

[0016] In summary, this invention provides a collaborative accounting method based on consumption data and green rights traceability, starting from the energy consumption side. This method can accurately calculate non-fossil energy electricity consumption in provincial and municipal administrative regions, providing systematic and reliable technical support for government energy conservation assessments, renewable energy responsibility weight calculations, non-fossil energy consumption accounting, and guiding enterprises to promote non-fossil energy consumption.

[0017] (II) Technical Solution This invention adheres to the principles of "user-centricity" and "consumption-based approach," with its core being the construction of a collaborative accounting model that prioritizes the end-user consumption side of non-fossil energy and supplements it with green certificate trading. This technical solution determines the total non-fossil energy electricity consumption of the entire province through a provincial-level accounting model, and then combines this with a municipal-level accounting model and allocation mechanism to achieve accurate accounting of non-fossil energy electricity consumption at both the provincial and municipal levels. The specific steps are as follows: (1) Determination of basic data collection and accounting boundaries First, determine the accounting period (e.g., monthly, quarterly, annual) and accounting boundaries (clarify the provincial and municipal administrative regions), and collect the following basic data to form a complete and traceable dataset: 1. Total electricity consumption of the province and its prefectures (referred to as...) , ,in Represents a provincial-level administrative region. (Representing a prefecture-level administrative region); 2. Various electricity market transaction data: Provincial renewable energy bilateral agreement electricity trading volume The total amount of green electricity procured through centralized bidding in province p ( ), Local bilateral agreement transaction of renewable energy electricity ( ); 3. Data on inter-provincial power flow and green certificate transfer: data from other provinces Towards Net inflow of non-fossil energy electricity (green electricity) into the province ; 4. Distributed and self-owned power plant generation data for self-consumption: Province's self-generated and self-consumed renewable energy electricity , City's self-generated and self-consumed renewable energy electricity ; 5. Green electricity data to be allocated in the spot market: Green electricity volume in the provincial spot market that is yet to be allocated and traced ; The municipal and provincial spot markets share the green electricity volume of the city. .

[0018] (2) Provincial non-fossil energy electricity consumption accounting model This accounting framework is based on the province's non-fossil energy electricity consumption side, constructing a provincial accounting model that primarily focuses on end-user consumption and supplements it with green certificate rights. The model uses the province's actual non-fossil energy consumption as its statistical basis, covering electricity users involved in medium- and long-term transactions and spot transactions. It includes net inflows of green electricity from both within and outside the province, as well as locally generated and consumed non-fossil energy. The total provincial non-fossil energy electricity consumption is decomposed into five sources, as detailed in the following formula:

[0019] In the formula: : The province's non-fossil energy electricity consumption is based on the user's energy consumption side; : The electricity volume traded under the provincial bilateral agreement for renewable energy (including direct market access and agent purchasers) belongs to... The province has traceable non-fossil energy power through medium- and long-term power trading contracts; : Province The electricity volume traded under the city's bilateral agreement for renewable energy is a type of renewable energy electricity traded locally at the city level, independent of provincial-level transactions. : Green electricity in the provincial spot market that is pending allocation and traceability is non-fossil energy electricity whose consumption attribution is determined through allocation. :Towards The total number of other provinces with net non-fossil energy electricity input; other provinces Towards The net inflow of green electricity transactions in the province reflects the non-fossil energy portion of the physical electricity transmission across provinces; : The total number of renewable energy types generated and consumed by the province, including distributed photovoltaic power and self-supplied biomass at power plants; : The province's self-generated and self-consumed renewable energy electricity, i.e. Non-fossil energy power that is not connected to the main power grid within the province and is consumed by users themselves.

[0020] (3) Accounting model for non-fossil energy electricity consumption at the prefecture-level city level This accounting framework is based on the municipal-level non-fossil energy electricity consumption side, constructing a municipal-level accounting model that primarily focuses on municipal-level end-user consumption and supplements it with provincial-level overall coordination. This model uses the actual non-fossil energy consumption of municipal-level end-users as the core of the accounting, classifying users into three categories: direct market entry, agency power purchase, and residential + agricultural users. It covers medium- and long-term transactions, spot transactions, and municipal-level self-generated and self-consumed electricity, decomposing the total municipal-level non-fossil energy electricity consumption into four sources. The specific formula is as follows:

[0021] In the formula: : The city's total non-fossil energy electricity consumption during the accounting period; : The amount of green electricity traded through bilateral agreements in the city refers to For urban electricity users (including those who directly enter the market and those who purchase electricity through agents), the green electricity consumption volume that is directly contracted with renewable energy power generation companies within and outside the province through bilateral agreements in the medium- and long-term electricity market and clearly assigned to them will have its corresponding green certificates transferred to the users along with the transactions; : Provincial centralized bidding for green electricity volume The city's allocated electricity volume is calculated using the following formula:

[0022] in, for The total amount of green electricity procured through centralized bidding by the province, for Municipal electricity consumption allocation coefficient; ( The municipal electricity consumption allocation factor is calculated using the following formula:

[0023] in, for The city's total electricity consumption for The province's total electricity consumption; : City-generated and self-consumed non-fossil electricity refers to Non-fossil energy consumption in localized projects such as distributed photovoltaic power generation and self-consumption within the city's geographical area mainly serves as a safety net for residential and agricultural users; : The green electricity in the city's spot market that is pending traceability is non-fossil energy electricity whose consumption attribution is determined through an allocation method.

[0024] (4) Accounting process for non-fossil energy electricity consumption at the provincial and municipal levels The accounting for non-fossil energy electricity consumption at both the provincial and municipal levels shall be carried out in accordance with the following steps: Step S1: Basic Data Collection and Accounting Boundary Determination: Complete the determination of the accounting cycle and accounting boundary, collect all data from the "Basic Data Collection and Accounting Boundary Determination" section of this plan, and form the basic data set for collaborative accounting; Step S2: Provincial Non-Fossil Energy Consumption Calculation: Based on the data collected in Step S1, the provincial non-fossil energy electricity consumption calculation model is applied, and the calculation is performed using the formula... ,calculate Non-fossil energy electricity consumption on the energy consumption side of the province To achieve a synergistic unity between physical electricity consumption and green rights; Step S3: Determination of City-Level Apportionment Coefficient and Verification of Active Consumption: Based on "Consumer Responsibility" and "Local Principle," the formula is used... calculate Municipal electricity allocation coefficient Simultaneously verified The amount of non-fossil energy electricity actively consumed by the city through market mechanisms, namely (Bilateral agreement on green electricity trading) and (Self-generated and self-consumed non-fossil electricity), this portion of electricity is considered as... Priority deduction items and basic components of the city's non-fossil energy electricity consumption; Step S4: Summarize provincial centralized green electricity distribution and municipal final consumption: Total green electricity procured through centralized bidding in the province ( )and Green electricity volume in the provincial spot market that is yet to be allocated and cannot be traced ( The "provincial-level green batteries" are composed of [various components], and are allocated according to the sharing coefficient determined in step S3. Proportional allocation The city received ( Provincial centralized bidding for green electricity volume (City's allocated electricity) and ( (Green electricity consumption borne by city-affiliated electricity purchasers); finally, through the formula Summary The city's final non-fossil energy electricity consumption.

[0025] (III) Beneficial Effects This invention is an accounting model initiated from the "energy consumption side" based on the principles of "locality" and "consumer responsibility." This model integrates multi-source data, including direct green electricity transactions, green certificate transfers, self-consumption, and market allocation, to achieve comprehensive and accurate measurement of non-fossil energy consumption at the user end. This method accurately reflects the true green consumption levels of various cities and enterprises. Through clear accounting guidance, it effectively incentivizes enterprises to actively participate in green electricity trading, directly boosting non-fossil energy consumption and promoting the transformation of local energy structures.

[0026] This invention constructs an accounting system that combines "provincial-level overall accounting + regional interconnection considerations + detailed allocation at the prefecture-level city level," and addresses the inconsistency in statistical results across different provincial and prefecture-level levels by incorporating the "local principle." This framework ensures both the integrity of provincial macro-data and the accuracy of prefecture-level micro-data. The entire scheme employs clear calculation formulas, and all required data is sourced from existing mature information systems, such as power trading platforms and power grid dispatching systems, thus combining scientific rigor with engineering feasibility.

[0027] This invention deeply integrates electricity trading data, green certificate trading data, distributed energy data, and grid dispatch data to construct a clear green electricity traceability mechanism. This mechanism ensures that the physical flow and environmental rights of each kilowatt-hour of green electricity have a clear attribution, avoiding accounting biases caused by data fragmentation and improving the accuracy and reliability of non-fossil energy electricity consumption accounting.

[0028] This invention adopts a "direct transaction + unified allocation" paradigm, which fully respects the autonomous choice of market participants, such as allowing enterprises to obtain green electricity through bilateral transactions. Furthermore, by using a unified allocation method based on total electricity consumption, it ensures fairness in the green responsibility borne by all user groups, including residents, agricultural users, and agents purchasing electricity. This design is applicable to interconnected power grid systems where physical boundaries are difficult to define precisely, achieving a fair allocation of consumption responsibility, providing institutional support for the efficient operation of the green electricity and green certificate markets, and effectively stimulating the vitality of the green energy market.

[0029] This invention addresses regional interconnection issues at the provincial level and calculates consumption based on total electricity consumption at the prefecture-level city level, effectively avoiding the problem of unclear physical boundaries between cities. This invention scientifically prevents the inflated or deflated consumption figures caused by pure green certificate trading, ensuring the accuracy and fairness of green consumption accounting under a unified national electricity market, and providing key technical support for the statistics and management of non-fossil energy electricity consumption under the "dual carbon" target.

[0040] II. Provincial Non-Fossil Energy Electricity Consumption Calculation Based on the appendix Figure 3 The provincial non-fossil energy consumption accounting model uses the provincial accounting formula to calculate the total non-fossil energy electricity consumption in Shaanxi Province: Substitute into Shaanxi Province ( (Provincial) data calculation: (1) Substitute the data into each item: 10,000 kilowatt-hours =120 million kilowatt-hours, 10,000 kilowatt-hours Tens of thousands of kilowatt-hours; (2) Calculation process: Tens of thousands of kilowatt-hours; (3) Results: In the third quarter of 2024, the non-fossil energy electricity consumption on the energy consumption side of Shaanxi Province was... 10,000 kilowatt-hours, combined with attached Figure 3 Analysis of power sources shows that medium- and long-term transactions account for the largest share (68.97%), while inter-provincial imports account for 16.09%, reflecting the characteristics of non-fossil energy consumption in the province being mainly based on contracted electricity volume and supplemented by inter-provincial complementarity.

[0041] III. Determination of Electricity Allocation Coefficient and Active Consumption at the Municipal Level (1) Electricity allocation coefficient in Xi'an calculate Based on the principles of "locality" and "fair allocation of electricity consumption," the electricity allocation coefficient for Xi'an City is calculated using the following formula. .

[0042] According to the formula Substitute the data: (i.e., 24%), which is consistent with the proportion of Xi'an's total electricity consumption in the province, providing a basis for the centralized allocation of green electricity at the provincial level.

[0043] (2) Verification of active consumption in Xi'an "Active consumption" refers to non-fossil energy electricity generated independently by Xi'an City through market mechanisms, without participating in provincial unified allocation, reflecting the design concept of "respecting the market entity's right to choose independently." This portion of electricity includes green electricity traded through local bilateral agreements and self-generated and self-consumed non-fossil energy. Active consumption Tens of thousands of kilowatt-hours; IV. Calculation of Final Consumption at the Municipal Level (1) The amount of green electricity generated through centralized bidding in Shaanxi Province City's allocated electricity ( )calculate According to the formula =18000 × 0.24 = 43.2 million kilowatt-hours; This portion of the electricity supply covers the needs of users in Xi'an who do not directly participate in market transactions, and is correspondingly attached. Figure 2 The apportionment categories for "agent-purchased electricity" and "spot trading" in China.

[0044] (2) Calculation of final consumption in Xi'an Based on the municipal-level accounting formula, the electricity consumption of various non-fossil energy sources is summarized to calculate the final consumption of Xi'an City: , Substitute the data into each item: Tens of thousands of kilowatt-hours; Results Verification: Xi'an's non-fossil energy consumption accounts for 23.18% of the province's total, which is basically consistent with its electricity consumption share of 24%. The slight difference stems from the allocation logic of green electricity to be allocated at the provincial level, verifying the coordination between the provincial and municipal accounting results and solving the problem of "provincial and municipal accounting deviation" in existing technologies.

[0045] V. Summary of Implementation Results This embodiment uses specific calculations from Shaanxi Province and Xi'an City, combined with the appendix. Figure 2 Source tracing tools and attachments Figure 3 The provincial-level accounting model fully verifies the technical solution of this invention and achieves the following effects: Clear data traceability: All accounting data comes from existing power trading and dispatching systems, eliminating the need to build a new platform and reducing implementation costs. Data categories and appendices... Figure 2 The green electricity trading and traceability classification are matched one by one to ensure that the physical flow of each kilowatt-hour of green electricity and the ownership of environmental rights are clear.

[0046] The accounting logic is rigorous: by adopting the model of "provincial-level unified accounting + municipal-level allocation", it ensures both the integrity of the province's total non-fossil energy consumption and the accuracy of municipal-level data, avoiding double counting and logical confusion.

[0047] Fairness is paramount: 77 million kilowatt-hours of green electricity actively consumed by Xi'an City are directly included in local consumption, while the remaining electricity is allocated according to the proportion of electricity consumption, taking into account both market autonomy and user fairness, and effectively stimulating enterprises' enthusiasm to participate in green electricity trading.

[0048] In summary, this embodiment fully demonstrates that the present invention can effectively solve the technical problems of existing non-fossil energy electricity consumption accounting and provide reliable technical support for green energy management at the provincial and local levels under the "dual carbon" target.
