Description

Technical Field

[0001] This invention relates to the field of carbon emission metering technology in power systems, specifically to a method, system, equipment, and storage medium for carbon emission reduction metering on the electricity consumption side of a distribution area. Background Technology

[0002] With the introduction of the "dual carbon" target, carbon emission measurement during the construction of new power systems has become a fundamental issue that urgently needs to be addressed. Currently, carbon emission measurement and accounting methods are relatively mature on the generation side of the power grid system. Although almost all direct carbon emissions in the power industry originate from the generation stage, with virtually no carbon emissions generated during the use of electricity, electricity production is driven by electricity demand, and the power generation, transmission, and consumption in the power system are in instantaneous equilibrium. Therefore, establishing a carbon metering system on the electricity consumption side can provide crucial data references for guiding users to improve electricity efficiency, thereby achieving the goals of saving and rationally using electricity. Summary of the Invention

[0003] To address the problem that carbon emissions cannot be measured on the electricity consumption side of the power grid system in the prior art, this invention provides a method, system, equipment, and storage medium for measuring carbon emission reduction on the electricity consumption side of a distribution transformer area.

[0004] This invention is achieved through the following technical solution: a method for carbon emission reduction metering on the electricity consumption side of a distribution transformer area, comprising the following steps:

[0005] S1: Obtain the nodal carbon potential of the distribution network node where the transformer substation is located, the electricity output of renewable energy within the substation, and the electricity consumption of the substation. Nodal carbon potential refers to the carbon emissions equivalent to those on the generation side caused by a unit of electricity consumption at that node, typically expressed in kgCO2 / kWh. For power generation nodes, the nodal carbon potential is equivalent to the real-time carbon emission intensity of the power plant. Additionally, the electricity consumption of the substation refers to the electricity consumed by the electricity user side of the substation. It can be positive or negative. A positive value indicates that the distribution network supplies electricity to the substation as an external power source when there is no renewable energy or the renewable energy output is insufficient to support the electricity demand of the load within the substation. A negative value indicates that the renewable energy output within the substation is sufficient to support the electricity demand of the load within the substation, and the surplus is sent back to the distribution network. The electricity consumption of the substation can be obtained by reading the substation's master meter. The specific process is as follows:

[0006] The main grid can obtain the instantaneous carbon potential of all nodes based on carbon flow calculation technology. Therefore, distribution network nodes can obtain the instantaneous carbon potential ρ1 of their corresponding main grid nodes, and obtain the power generation P1 provided by the main grid nodes to the distribution network nodes from the acquisition equipment at the substation gates of the distribution network nodes. In addition, carbon cost per unit of power generation can be calculated for each power generation node within the distribution network node, specifically by obtaining the instantaneous carbon potential of each power generation node. The power generation capacity is obtained from the acquisition equipment of each power node within the distribution network node. Then, ignoring line impedance, it can be assumed that the instantaneous carbon potential of all nodes on the distribution network line is consistent. Following the principle of proportional sharing, the node carbon potential e of the distribution network node where the transformer substation is located can be calculated as follows: The network topology of the distribution network node is tree-shaped, radial, or ring-shaped.

[0007] S2: Obtain the carbon emissions per unit of alternative energy for each electricity substitution load within the distribution area: The specific process is as follows: The energy source of the electricity substitution load is electricity and other energy sources that directly generate carbon emissions. The energy sources that directly generate carbon emissions mainly refer to fossil fuels. For example, the electricity substitution load includes, but is not limited to: automobiles powered by gasoline and electricity, automobiles powered by diesel and electricity, heating equipment powered by coal and electricity, dryers powered by coal and electricity, and heating equipment powered by natural gas and electricity. The carbon emissions per unit of alternative energy refer to the carbon emissions generated by the equivalent effect of a unit of electricity when other energy sources that directly generate carbon emissions provide energy to the electricity substitution load. For example, if one kilowatt-hour of electricity can power an electric vehicle for 10 kilometers, and the gasoline required to power the vehicle for the same distance is 0.7 liters, then 0.7 liters of gasoline will produce 1.6 kilograms of carbon dioxide. Therefore, the carbon emissions per unit of alternative energy are 1.6 kg CO2.

[0008] S3: Obtain the electricity consumed by each electricity substitution load within the distribution area during the metering period, and combine this with the nodal carbon potential of the distribution network node where the distribution area is located, the electricity output of new energy sources within the distribution area, the electricity consumed by the distribution area, and the carbon emission of each electricity substitution load per unit of substituted energy to calculate the carbon emission reduction of each electricity substitution load within the distribution area during the metering period. The specific steps are as follows:

[0009] (1) Divide the metering time into multiple time periods and obtain the electricity consumption of the distribution area and the electricity output of new energy sources in the distribution area in each time period, so as to calculate the electricity provided by the distribution network node to the distribution area in each time period.

[0010] (2) Obtain the node carbon potential of the distribution network node where the transformer area is located in each time period, and calculate the total carbon emissions of the transformer area during the metering time period by combining the electricity provided by the distribution network node to the transformer area in each time period.

[0011] (3) Calculate the total electricity consumption of the transformer area within the metering time period based on the electricity consumption of the transformer area within each time period, and calculate the carbon emissions generated per unit of electricity consumed in the transformer area in combination with the total carbon emissions of the transformer area within the metering time period.

[0012] (4) Subtract the carbon emissions generated per unit of electricity consumed in the power distribution area from the carbon emissions per unit of alternative energy of each power substitution load to obtain the carbon emission reduction per unit of each power substitution load.

[0013] (5) The carbon emission reduction of each power substitution load within the distribution area during the metering time is calculated based on the unit carbon emission reduction of each power substitution load and the electricity consumed by each power substitution load within the distribution area during the metering time.

[0014] The above calculation process is illustrated in the following example: The metering time is set to one day, divided into 24 hours. The electricity consumption data of the distribution area and the electricity output of renewable energy sources within the area are obtained for each hour. This allows the calculation of the electricity supplied to the distribution area by the distribution network node each hour. For example, if the electricity consumption data of the distribution area in one hour is 20 kWh, and the electricity output of renewable energy sources within the area in one hour is 10 kWh, then the electricity supplied to the distribution area by the distribution network node in one hour is 10 kWh. This process is repeated to calculate the electricity supplied to the distribution area by the distribution network node throughout the day. T = 1, 2, 3, ..., 24.

[0015] Then, the nodal carbon potential of the distribution network node where the transformer area is located is calculated every hour to obtain the nodal carbon potential data of the distribution network node within a day. Given T = 1, 2, 3, ..., 24, the total carbon emissions of the distribution area in one day can be calculated as follows: Among them, when W t When the value is negative, it means that when the distribution area releases electricity to the distribution network, all the electricity in the area is provided by renewable energy sources within the area, and no carbon emissions are generated on the generation side. Therefore, the corresponding nodal carbon potential data e of the distribution network node at this time is... t It is zero.

[0016] Then, add up the electricity consumption of the transformer area over 24 hours to obtain the total electricity consumption W of the transformer area in one day. 总 Then divide the total carbon emissions F of the district in one day by the total electricity consumption W. 总 This gives us the carbon emissions A generated on the generation side for each unit of electricity consumed within the transformer area, where A = F / W. 总 .

[0017] Then, the carbon emission A generated per unit of electricity consumed in the distribution area is subtracted from the carbon emission B per unit of alternative energy of each electricity substitution load to obtain the carbon emission reduction per unit of electricity substitution load, C=AB.

[0018] Finally, multiply the unit carbon emission reduction C of each electricity substitution load by the electricity consumption W of each electricity substitution load in one day. x The carbon emission reduction W of each electricity substitution load in the transformer area can then be calculated within a day. 减 Among them, W 减 =C*W x .

[0019] The essence of this invention is: by first calculating the carbon emissions generated per unit of electricity consumed in the power distribution area, then calculating the carbon emission reduction per unit of electricity consumed and per unit of alternative energy consumed, and finally multiplying by the total electricity consumed by the electricity-substituted load, the carbon emission reduction can be calculated. Thus, the carbon emission reduction brought about by the electricity-substituted load can be accurately measured from the perspective of the electricity user, which helps to encourage users to improve electricity efficiency, use electricity rationally, save electricity, and reduce carbon emissions.

[0020] A system for carbon emission reduction metering at the electricity consumption side of a distribution transformer area, applying the above method, has the following specific framework: A first data acquisition unit is used to acquire the nodal carbon potential of the distribution network node where the distribution transformer area is located, the electricity output of new energy sources within the distribution transformer area, and the electricity consumption of the distribution transformer area; the working process is described in step S1. A second data acquisition unit is used to acquire the carbon emissions per unit of alternative energy for each electricity substitution load within the distribution transformer area; the working process is described in step S2. A calculation unit is used to acquire the electricity consumed by each electricity substitution load within the distribution transformer area during the metering time, and, combined with the acquired nodal carbon potential of the distribution network node where the distribution transformer area is located, the electricity output of new energy sources within the distribution transformer area, the electricity consumption of the distribution transformer area, and the carbon emissions per unit of alternative energy for each electricity substitution load, calculates the carbon emission reduction of each electricity substitution load within the distribution transformer area during the metering time. The specific working process of this system is to adopt the above-mentioned method for carbon emission reduction metering at the electricity consumption side of the distribution transformer area; the working process is described in step S3.

[0021] A device for measuring carbon emission reduction at the electricity consumption side of a distribution station includes a processor and a memory. The memory stores a computer program, and the processor executes the steps of the above-described method for measuring carbon emission reduction at the electricity consumption side of a distribution station by calling the computer program stored in the memory.

[0024] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a method, system, equipment, and storage medium for carbon emission reduction metering on the electricity consumption side of a distribution area. The method for carbon emission reduction metering on the electricity consumption side of a distribution area first obtains the nodal carbon potential of the distribution network node where the distribution area is located, the power output of new energy sources in the distribution area, and the power consumption of the distribution area, thereby calculating the carbon emissions generated per unit of power consumption in the distribution area. Then, it obtains the carbon emissions per unit of alternative energy of each power substitution load in the distribution area and the power consumption of each power substitution load in the distribution area within the metering time, thereby calculating the carbon emission reduction of each power substitution load in the distribution area. This not only realizes the metering of carbon emissions from the electricity consumption side of the distribution area, but also encourages users to improve electricity efficiency, use electricity rationally, and save electricity by calculating the carbon emission reduction of each power substitution load, which helps to reduce carbon emissions; it solves the technical problem in the prior art that carbon emissions cannot be metered on the electricity consumption side of the power grid system.

[0033] The aforementioned system for carbon emission reduction metering at the electricity consumption side of a distribution transformer area specifically employs a method for carbon emission reduction metering at the electricity consumption side of the distribution transformer area, such as... Figure 1 As shown, it includes the following steps:

[0034] S1: Obtain the nodal carbon potential of the distribution network node where the transformer substation is located, the electricity output of renewable energy within the substation, and the electricity consumption of the substation. Nodal carbon potential refers to the carbon emissions equivalent to those on the generation side caused by a unit of electricity consumption at that node, typically expressed in kgCO2 / kWh. For power generation nodes, the nodal carbon potential is equivalent to the real-time carbon emission intensity of the power plant. Additionally, the electricity consumption of the substation refers to the electricity consumed by the electricity user side of the substation. It can be positive or negative. A positive value indicates that the distribution network supplies electricity to the substation as an external power source when there is no renewable energy or the renewable energy output is insufficient to support the electricity demand of the load within the substation. A negative value indicates that the renewable energy output within the substation is sufficient to support the electricity demand of the load within the substation, and the surplus is sent back to the distribution network. The electricity consumption of the substation can be obtained by reading the substation's master meter. The specific process is as follows:

[0035] The main grid can obtain the instantaneous carbon potential of all nodes based on carbon flow calculation technology. Therefore, distribution network nodes can obtain the instantaneous carbon potential ρ1 of their corresponding main grid nodes, and obtain the power generation P1 provided by the main grid nodes to the distribution network nodes from the acquisition equipment at the substation gates of the distribution network nodes. In addition, carbon cost per unit of power generation can be calculated for each power generation node within the distribution network node, specifically by obtaining the instantaneous carbon potential of each power generation node. The power generation capacity is obtained from the acquisition equipment of each power node within the distribution network node. Then, ignoring line impedance, it can be assumed that the instantaneous carbon potential of all nodes on the distribution network line is consistent. Following the principle of proportional sharing, the node carbon potential e of the distribution network node where the transformer substation is located can be calculated as follows: The network topology of the distribution network node is tree-shaped, radial, or ring-shaped.

[0036] S2: Obtain the carbon emissions per unit of alternative energy for each electricity substitution load within the distribution area: The specific process is as follows: The energy source of the electricity substitution load is electricity and other energy sources that directly generate carbon emissions. The energy sources that directly generate carbon emissions mainly refer to fossil fuels. For example, the electricity substitution load includes, but is not limited to: automobiles powered by gasoline and electricity, automobiles powered by diesel and electricity, heating equipment powered by coal and electricity, dryers powered by coal and electricity, and heating equipment powered by natural gas and electricity. The carbon emissions per unit of alternative energy refer to the carbon emissions generated by the equivalent effect of a unit of electricity when other energy sources that directly generate carbon emissions provide energy to the electricity substitution load. For example, if one kilowatt-hour of electricity can power an electric vehicle for 10 kilometers, and the gasoline required to power the vehicle for the same distance is 0.7 liters, then 0.7 liters of gasoline will produce 1.6 kilograms of carbon dioxide. Therefore, the carbon emissions per unit of alternative energy are 1.6 kg CO2.

[0037] S3: Obtain the electricity consumed by each energy substitution load within the distribution area during the metering period, and combine this with the nodal carbon potential of the distribution network node where the distribution area is located, the electricity output of new energy sources within the distribution area, the electricity consumed by the distribution area, and the carbon emission of each energy substitution load per unit of energy substitution energy to calculate the carbon emission reduction of each energy substitution load within the distribution area during the metering period, such as... Figure 2 As shown, the specific steps are as follows:

[0038] (1) Divide the metering time into multiple time periods and obtain the electricity consumption of the distribution area and the electricity output of new energy sources in the distribution area in each time period, so as to calculate the electricity provided by the distribution network node to the distribution area in each time period.

[0039] (2) Obtain the node carbon potential of the distribution network node where the transformer area is located in each time period, and calculate the total carbon emissions of the transformer area during the metering time period by combining the electricity provided by the distribution network node to the transformer area in each time period.

[0040] (3) Calculate the total electricity consumption of the transformer area within the metering time period based on the electricity consumption of the transformer area within each time period, and calculate the carbon emissions generated per unit of electricity consumed in the transformer area in combination with the total carbon emissions of the transformer area within the metering time period.

[0041] (4) Subtract the carbon emissions generated per unit of electricity consumed in the power distribution area from the carbon emissions per unit of alternative energy of each power substitution load to obtain the carbon emission reduction per unit of each power substitution load.

Therefore, the corresponding nodal carbon potential data e of the distribution network node at this time is... t It is zero.

[0045] Then, add up the electricity consumption of the transformer area over 24 hours to obtain the total electricity consumption W of the transformer area in one day. 总 Then divide the total carbon emissions F of the district in one day by the total electricity consumption W. 总 This gives us the carbon emissions A generated on the generation side for each unit of electricity consumed within the transformer area, where A = F / W. 总 .

[0046] Then, the carbon emission A generated per unit of electricity consumed in the distribution area is subtracted from the carbon emission B per unit of alternative energy of each electricity substitution load to obtain the carbon emission reduction per unit of electricity substitution load, C=AB.

[0047] Finally, multiply the unit carbon emission reduction C of each electricity substitution load by the electricity consumption W of each electricity substitution load in one day. x The carbon emission reduction W of each electricity substitution load in the transformer area can then be calculated within a day. 减 Among them, W 减 =C*W x .
