Description

Technical Field

[0001] This application relates to the field of power system technology, specifically to a method, system, and medium for calculating the comprehensive carbon emission factor of a provincial power grid. Background Technology

[0002] For the power industry, calculating the emission factor on the power supply side is a crucial bridge connecting electricity consumption and carbon emissions. Therefore, it is necessary to develop a reasonable calculation model for the emission factor on the power supply side as soon as possible.

[0003] Research on carbon emission accounting by power grid companies worldwide started relatively late. Statistical data on the types of electricity consumed and the types of power generation for exchanged electricity in most regions are incomplete. Furthermore, against the backdrop of large-scale development of distributed power sources, the increasing proportion of renewable energy, the expanding scale of inter-regional power transmission, the gradual conversion of thermal power units into peak-shaving and backup power sources, and the gradual advancement of bidirectional interactive electrification, the spatial and temporal differences in power sources across power grids at all levels have significantly increased. The fluctuations in power generation from different generation types and the bidirectional load on-grid electricity are also drastic. Continuing to use the regional power grid average emission factor for carbon emission accounting by power grid companies will result in significant errors. Moreover, there are no mature calculation methods for power grid emission factors considering different time scales (year, month, day) and provincial levels, leading to inaccuracies in the actual calculation of electricity consumption in various regions. When calculating carbon emissions for a specific province, two existing accounting methods are used: the material conservation method and the emission factor method. However, there are significant differences in the temporal and spatial distribution of power resources between different provinces. Calculating the carbon emissions of a province solely using the emission factor of its own region will result in substantial errors. Summary of the Invention

[0004] The purpose of this application is to propose a method, system, and medium for calculating the comprehensive carbon emission factor of provincial power grid supply, which helps to avoid the impact of "carbon leakage" and helps power grid companies achieve accurate carbon emission accounting.

[0005] The technical solution of this application:

[0006] In a first aspect, embodiments of this application provide a method for calculating the comprehensive carbon emission factor of a provincial power grid, comprising the following steps:

[0007] Determine the sources of electricity consumed by the provincial power grid, determine the power generation of the main power plants in the province, and know the amount of electricity sent to other provinces and the amount of electricity received by the main grid from other provinces;

[0008] The total power generation of each main power plant in the province is statistically analyzed, and the power generation type is determined.

[0009] Obtain various types of electricity transmitted to other provinces;

[0010] The total carbon emissions of the main grid are obtained by multiplying the electricity consumption of each type of grid by the corresponding carbon emission factor.

[0011] The comprehensive carbon emission factor of a provincial power grid is obtained by dividing the total carbon emissions of the main grid by the total electricity consumption of the main grid.

[0012] The specific method for obtaining the various types of electricity transmitted to other provinces is as follows: after deducting the known amount of electricity transmitted to other provinces, the electricity is then allocated according to the proportion of thermal, hydro, wind, and solar power generation consumed by the main grid of the province, thus obtaining the various types of electricity transmitted to other provinces.

[0013] The calculation methods for the power generation of the main power plants in the province, the power sent to the main grid, and the power sent to the main grid are shown in equation (1):

[0014]

[0015] In the formula E 发电厂 E represents the total power generation of power plants within the province. 发电厂,k This represents the power generation of the kth type of power plant within the province. For the k-th type of electricity transmitted to the main power grid of other provinces,

[0016] The calculation method for various types of power generation transmitted to other provinces is as shown in equation (2):

[0017]

[0018] In the formula, PY represents the provinces that are known to transmit various types of electricity to other provinces; P represents all provinces that transmit electricity to other provinces. The k-th type of power generation is transmitted to the p-th province; To transmit the total electricity to the p-th province; To receive the k-th type of power generation from the p-th province; Let p be the total electricity received from the p-th province.

[0019] The calculation methods for various types of power generation absorbed by the provincial power grid are as follows:

[0020]

[0021] After receiving various types of electricity consumed from different regions within the province, the total carbon dioxide emissions from power generation companies are:

[0022]

[0023] In the formula: The unit comprehensive carbon dioxide emissions per unit of power generation for the k-th type of power generation enterprise in region i, expressed in tons of carbon dioxide per megawatt-hour, CE i Let be the total carbon emissions of region i.

[0024] Power supply emission factor of region i This can be derived from equation (5):

[0025]

[0026] Secondly, embodiments of this application provide a system for calculating the comprehensive carbon emission factor of a provincial power grid, including:

[0029] The module for acquiring electricity transmitted to other provinces is used to obtain various types of electricity transmitted to other provinces.

[0030] The total carbon emission calculation module is used to obtain the electricity consumption of various types in the provincial main grid, and multiply the electricity consumption of each type by the corresponding carbon emission factor to obtain the total carbon emission of the main grid.

[0031] The comprehensive carbon emission factor calculation module is used to divide the total carbon emissions of the main grid by the total electricity consumption of the main grid to obtain the comprehensive carbon emission factor of the provincial power grid.

[0032] The module for obtaining electricity transmitted to other provinces includes a proportional allocation unit. After deducting the known amount of electricity transmitted to other provinces of each type, the proportional allocation unit allocates the electricity according to the proportion of thermal, hydro, wind and solar power generation absorbed by the main grid of the province, thereby obtaining the amount of electricity transmitted to other provinces of each type.

[0033] The power generation determination module includes a power generation calculation unit for power plants within the province's main grid, a power generation calculation unit for power transmitted to the main grid, and a power generation calculation unit for power transmitted to the main grid.

[0035] Fourthly, embodiments of this application provide a computer-readable storage medium storing program code, which, when executed by a processor, implements the steps of the method for calculating the comprehensive carbon emission factor of provincial power grid supply as described above.

[0036] Compared with existing technologies, the beneficial effects of this application are as follows: This application establishes a calculation model for the power exchange of provincial power grids by analyzing the influencing factors of power supply emission factors at all levels of power grids, and compiles a calculation method covering provincial power grids. This method helps to avoid the impact of "carbon leakage" and assists power grid companies in achieving accurate carbon emission accounting. Attached Figure Description

[0038] Figure 2 This is a schematic diagram of the method flow of an embodiment of this application;

[0039] Figure 3 This is a system block diagram of an embodiment of this application. Detailed Implementation

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0041] like Figure 2 The flowchart shown illustrates a method for calculating the comprehensive carbon emission factor of a provincial power grid. The implementation steps are as follows:

[0042] S1. First, clarify the source of the electricity consumed by the provincial power grid, namely the power generation of the main power plants in the province, and know the amount of electricity sent to other provinces and the amount of electricity received by the main grid from other provinces.

[0043] S2. Calculate the total power generation of each main power plant in the province and identify the power generation type.

[0044] S3. The unknown types of power generation transmitted to other provinces are allocated according to the proportion of thermal, hydro, wind, and solar power generation consumed by the main grid of the province after deducting the known types of power generation transmitted to other provinces. This yields the types of power transmitted to other provinces.

[0045] S4. After obtaining the electricity consumption of each type in the provincial main grid from steps S2 and S3, the total carbon emissions of the main grid can be obtained by multiplying the electricity consumption of each type by the corresponding carbon emission factor.

[0046] S5. Divide the total carbon emissions of the main grid by the total electricity consumed by the main grid to obtain the comprehensive carbon emission factor of the provincial power grid.

[0047] Provincial power grids are primarily based on a 500kV voltage level, and use 500kV substations as gateways for power exchange with other provincial power grids. This application proposes... Figure 1 The diagram shows the equivalent model of power exchange for different power generation types in a provincial power grid.

[0048] Where M represents the mainnet; E M-i E represents the amount of electricity injected into region i from the main grid via a 500kV transformer; i-M E represents the amount of electricity fed into the main grid from region i via a 500kV transformer; M- E represents the amount of electricity flowing from the main grid of this province to different provinces; M+ The amount of electricity injected into the main grid of this province from different provinces; H, S, F, and G represent four different types of power generation: thermal power, hydropower, wind power, and photovoltaic power. These represent the power generation of four types of power plants in the main grid: thermal, hydro, wind, and solar. These represent the power generation of four types of power plants within region i: thermal, hydro, wind, and solar.

[0049] Generally, there are three main sources of carbon emissions within a province: carbon emissions from electricity generated within the province and consumed by the province, carbon emissions from electricity exchange with other provinces, and carbon emissions from grid losses. This application proposes to include grid losses in the regional load. The calculation method for the total electricity consumed within the province and the electricity of each type of electricity consumed is shown in Equation (1).

[0050]

[0051] In the formula, AD represents the total electricity consumed within the province; E represents the electricity generated within the province and consumed by the province; AD k E represents the kth type of electricity consumed within the province, where k is one of four power generation types: thermal (H), hydro (S), wind (F), and solar (G); k Category k electricity generated within the province and consumed by the province; The main grid receives the k-th type of electricity from other provinces.

[0052] Based on formula (1), this application first calculates the electricity absorbed by the provincial power grid itself, and then calculates the electricity received (outflowed) by other regions of the provincial power grid according to the proportion of electricity generated by different types of power generation such as thermal, hydro, wind and solar power in the region to which the electricity belongs.

[0053] The calculation method for the total power generation and the power generation of each type in the province proposed in this application is shown in Equation (2):

[0054]

[0055] In the formula E 发电厂 E represents the total power generation of power plants within the province. 发电厂,k This represents the power generation of the kth type of power plant within the province. This refers to the k-th type of electricity transmitted to the main grid of other provinces. The variables in equation (2) are only related to the parameters of each type of power generation within the province.

[0056] At present, carbon emission management of most provincial power grids in my country is just beginning. There is no complete statistical data on the proportion of each type of power generation in the electricity consumption, nor has carbon footprint tracking been completed. In order to transmit various types of power generation to other provinces, the method proposed in this application is as follows: after deducting the known types of power generation transmitted to other provinces, the unknown types of power generation to be transmitted to other provinces are allocated according to the proportion of thermal, hydro, wind and solar power generation.

[0057] For the various types of power generation transmitted to other provinces, this application proposes a calculation method as shown in equation (3):

[0058]

[0059] In the formula, PY represents the provinces that are known to transmit various types of electricity to other provinces; P represents all provinces that transmit electricity to other provinces. The k-th type of power generation is transmitted to the p-th province; To transmit the total electricity to the p-th province; To receive the k-th type of power generation from the p-th province; Let p be the total electricity received from the p-th province.

[0060] This application proposes the following calculation methods for various types of power generation absorbed by the provincial power grid:

[0061]

[0062] After receiving various types of electricity consumed from different regions within the province, the total carbon dioxide emissions from power generation companies are:

[0063]

[0064] In the formula: Let represent the unit comprehensive carbon dioxide emissions of power generation by the k-th type of power generation enterprise in region i, expressed in tons of carbon dioxide per megawatt-hour (tCO2 / MWh). CE i Let be the total carbon emissions of region i.

[0065] Then the power supply emission factor of region i This can be derived from equation (6):

[0066]

[0067] like Figure 3 As shown, this application embodiment provides a system for calculating the comprehensive carbon emission factor of a provincial power grid, including:

[0068] The power consumption determination module 1 is used to determine the source of power consumption in the provincial power grid, determine the power generation of the main power plants in the province, and know the power sent to other provinces and the power received by the main grid from other provinces;

[0069] Statistical module 2 is used to calculate the total power generation of each main power plant in the province and determine the power generation type;

[0070] The module 3 for acquiring electricity transmitted to other provinces is used to obtain various types of electricity transmitted to other provinces.

[0071] Total carbon emission calculation module 4 is used to obtain the electricity consumption of each type in the main grid within the province, and multiply the electricity consumption of each type by the corresponding carbon emission factor to obtain the total carbon emission of the main grid.

[0072] The comprehensive carbon emission factor calculation module 5 is used to divide the total carbon emissions of the main grid by the total electricity consumption of the main grid to obtain the comprehensive carbon emission factor of the provincial power grid.

[0073] The module for obtaining electricity transmitted to other provinces includes a proportional allocation unit. After deducting the known amount of electricity transmitted to other provinces of each type, the proportional allocation unit allocates the electricity according to the proportion of thermal, hydro, wind and solar power generation absorbed by the main grid of the province, thereby obtaining the amount of electricity transmitted to other provinces of each type.

[0074] The power generation determination module includes a power generation calculation unit for power plants within the province's main grid, a power generation calculation unit for power transmitted to the main grid, and a power generation calculation unit for power transmitted to the main grid. The power generation calculation unit for power plants within the province's main grid is used to calculate the power generation of power plants within the province's main grid, the power transmission calculation unit for power transmitted to the main grid is used to calculate the power transmitted to the main grid, and the power transmission calculation unit for power transmitted to the main grid is used to calculate the power transmitted to the main grid.

[0075] The following table shows the power generation data of all power plants in a certain province.

[0076] Table 1. Power generation data of power plants in this province (100 million kWh)

[0077] <![CDATA[Hydropower E 发电厂,S > 63.00 <![CDATA[Wind Power E 发电厂,F > 2.96 <![CDATA[Photovoltaic E 发电厂,G > 2.96 <![CDATA[Total E 发电厂 > 182.55

[0078] To determine the emission factor of the provincial power grid, it is necessary not only to know the electricity generated by power plants of various power generation types within the province, but also to know the electricity exchange between the province and other provinces. As shown in the established provincial power grid emission factor calculation model, inter-provincial electricity exchange occurs only through the 500kV and above main grid. The processed data on electricity received from other provinces by the main grid is shown in Table 2.

[0079] Table 2. Electricity Data Received from Other Provinces by the Main Grid (100 Million kWh)

[0080]

[0081]

[0082] The distribution of various types of power plants is greatly influenced by geographical factors, resulting in uneven distribution of power generation types across provinces and cities in my country. Consequently, the types of power transmitted to other provinces also vary significantly depending on geographical location. Based on the model established above, the unknown power generation transmitted to other provinces is deducted from the known power generation of each type, and then allocated according to the proportions of thermal, hydro, wind, and solar power generation. Therefore, the processed power data transmitted from the province to the main grid of other provinces is shown in Table 3 below.

[0083] Table 3. Electricity data transmitted to the main power grid of other provinces (100 million kWh)

[0084]

[0085] This application calculates the power supply emission factor of the provincial power grid from the consumption side. Combining the above data with the calculation model of the proportion of each type of power generation in the power consumption of the provincial power grid, the power consumption situation in the province is calculated as shown in the table below.

[0087] thermal power 78.23 wind power 2.84 Photovoltaics 2.85 total 192.01

[0088] Based on equations (5) and (6), the emission factor of the power grid in the province is calculated to be 0.32tCO2 / MWh.
