Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0030] The terms “first”, “second”, and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by “first”, “second”, and the like are generally a category, and are not limited to the number of objects, for example, the first object can be one or more.

[0031] In the embodiments of the present application, a carbon emission information generation method, device, equipment, medium and program product are proposed to solve the problem of low accuracy of existing carbon emission calculation.

[0032] Referring to Figure 1 , Figure 1 is a flowchart of a carbon emission information generation method provided by an embodiment of the present application, as shown in Figure 1 , the method comprises the following steps:

[0033] Step 101, obtaining power plant construction data, power plant production data and coal mining and transportation data corresponding to a target power plant, the power plant construction data being used to represent energy consumption information of construction and / or demolition of the target power plant, the power plant production data being used to represent power generation information of the target power plant in a first preset time period, and the coal mining and transportation data being used to represent coal mining information of the target power plant in a second preset time period and transportation information of the coal mined in the second preset time period.

[0034] Specifically, the energy consumption information of construction and / or demolition of the target power plant can include energy consumption information of the target power plant in the construction and / or demolition process, for example, the energy consumption information of power plant construction mainly includes manufacturing of power generation equipment, construction of power plant, the energy consumption information of power plant demolition mainly includes waste disposal and demolition of power plant, etc. The power generation information can include the power generation amount of the target power plant in the first preset time period.

[0035] The coal mining information can be the mining information of each batch of incoming coal in the second preset time period, for example, can include the mining method of the coal source and the carbon emission intensity of each batch of coal. The transportation information of the coal can be the transportation information of each batch of incoming coal in the second preset time period, for example, can include the transportation method of each batch of coal and the corresponding carbon emission intensity of the coal transportation, in the case where it is difficult to determine the actual value, a preset value can also be selected as the default data of the carbon emission intensity of the coal transportation.

[0036] The first preset time period can be determined according to actual needs, for example, can be 15 minutes, which is consistent with the time period of the power market intraday spot trading quotation. It should be noted that the second preset time period can be greater than or equal to the first preset time period, and the second preset time period includes the first preset time period.

[0037] Step 102, determining a first carbon emission amount in the first preset time period according to the power plant production data, the first carbon emission amount including carbon emission amount in the process of coal-fired power generation.

[0038] It can be understood that the first carbon emission amount can be the carbon emission amount of the target power plant in the process of power generation in the first preset time period.

[0039] Step 103, determining a second carbon emission amount in the first preset time period according to the power plant construction data, the second carbon emission amount including at least one of carbon emission amount of manufacturing power generation equipment, carbon emission amount of constructing power plant, carbon emission amount of waste disposal and carbon emission amount of demolishing power plant.

[0040] Specifically, the carbon emissions from manufacturing the above-mentioned power generation equipment may refer to the carbon emissions from manufacturing the equipment required for the operation of the target power plant. The power generation equipment mainly includes main equipment of coal-fired power plants such as boilers, steam turbines, and generators, as well as auxiliary equipment such as coal mills, blowers, water steam circulation equipment, and environmental protection equipment. Among them, the implicit carbon emissions in the manufacturing process of the equipment are mainly calculated based on the equipment carbon label.

[0041] The above-mentioned carbon emissions from building a power plant may refer to the carbon emissions during the process of building a power plant. For example, building a power plant requires basic materials such as steel and concrete, as well as power consumption such as gasoline, diesel, and electricity. Among them, the embodied carbon emissions in the material manufacturing process are mainly calculated based on the average embodied carbon emissions of the materials. The carbon emissions from gasoline and diesel consumption can be calculated based on the standard quota values ​​for coal-fired power plant construction, and the carbon emissions from electricity can be calculated based on the national or regional average carbon emission factors for the current year.

[0042] The carbon emissions from waste treatment mentioned above may include the energy consumption required to treat the waste, the carbon dioxide emissions generated by the decomposition of the waste, etc. The carbon emissions from the dismantling of the power plant mentioned above mainly include the embodied carbon emissions from the diesel and electricity consumed during the dismantling process.

[0043] Step 104: Determine a third carbon emission amount within the first preset time period based on the coal mining and transportation data, where the third carbon emission amount includes carbon emissions during the coal mining and transportation process.

[0044] It can be understood that the third carbon emission amount may be the carbon emission amount generated by the target power plant during the first preset time period due to coal mining and transportation.

[0045] Step 105: Generate carbon emission information corresponding to the target power plant based on the first carbon emissions, the second carbon emissions, and the third carbon emissions, wherein the carbon emission information includes the total carbon emissions of the target power plant within the first preset time period, and the total carbon emissions are the sum of the first carbon emissions, the second carbon emissions, and the third carbon emissions.

[0046] Specifically, the carbon emission information may be used to indicate the carbon footprint of the target power plant during the first preset time period.

[0047] In the embodiments of the present application, the method for generating the carbon emission information can include the following steps: obtaining power plant construction data, power plant production data and coal mining and transportation data corresponding to a target power plant; determining a first carbon emission amount in a first preset time period according to the power plant production data, wherein the first carbon emission amount includes a carbon emission amount in a coal-fired power generation process; determining a second carbon emission amount in the first preset time period according to the power plant construction data, wherein the second carbon emission amount includes at least one of a carbon emission amount in manufacturing power generation equipment, a carbon emission amount in building a power plant, a carbon emission amount in waste disposal and a carbon emission amount in dismantling a power plant; determining a third carbon emission amount in the first preset time period according to the coal mining and transportation data, wherein the third carbon emission amount includes a carbon emission amount in a coal mining and transportation process; and determining a total carbon emission amount of the target power plant in the first preset time period based on the first carbon emission amount, the second carbon emission amount and the third carbon emission amount, so that the carbon footprint of the target power plant can be calculated in real time according to the scale of the first preset time period, thereby improving the accuracy of the carbon emission amount calculation.

[0048] Optionally, the first carbon emission amount includes at least one of a boiler coal-fired carbon emission amount, a combustion-supporting oil carbon emission amount and a desulfurization carbon emission amount.

[0049] The boiler coal-fired carbon emission amount is equal to a product of a coal consumption amount in the first preset time period, an average carbon content of coal, a coal combustion conversion efficiency and a preset value, and the coal consumption amount is equal to a product of a power generation amount in the first preset time period and a unit coal consumption intensity in the first preset time period.

[0050] The combustion-supporting oil carbon emission amount is equal to a product of an amount of combustion-supporting oil used in the first preset time period and a combustion-supporting oil carbon emission factor.

[0051] The desulfurization carbon emission amount is equal to a product of the coal consumption amount, a sulfur content of coal and a desulfurization efficiency.

[0052] Specifically, the boiler coal-fired carbon emission amount can refer to a carbon emission amount generated by a boiler device of the target power plant in a process of burning coal, the combustion-supporting oil carbon emission amount can refer to a carbon emission amount generated in a process of fuel-assisted combustion, and the desulfurization carbon emission amount can refer to a carbon emission amount caused by release of carbon elements in lime in a desulfurization process.

[0053] For example, a calculation formula of the combustion-supporting oil carbon emission amount is as follows:

[0054] A CO2 emission amount generated by the boiler coal-fired = a coal consumption amount × an average carbon content × 44 / 12

[0055]

[0056] wherein, coal_elec is the coal consumption for power generation in the t time period, C_rate is the carbon content of coal (according to the carbon verification of the power plant), comfu_eff is the coal combustion conversion efficiency (usually 99% is taken), and Δelec is the carbon emission factor of coal. t t elec is the power generation in the t time period. coal_rate is the unit coal consumption of the unit in the t time period. The t time period can be taken as every 15 minutes.

[0057] The calculation formula of the carbon emission of the combustion-supporting oil is as follows:

[0058]

[0059] Among them, coal_oil is the carbon emission of the combustion-supporting oil in the t time period, oil_comfu is the consumption of the combustion-supporting oil (tons), and CO2_den_heavyoil is the carbon emission factor of the combustion-supporting oil.

[0060] Specifically, the carbon emission of the combustion-supporting oil is generally mainly from heavy oil, and the carbon emission factor of the heavy oil can be calculated as 0.95 kg / L. The density of the heavy oil is generally taken as 2.98 kg CO2 / L, and the CO2_den_heavyoil is generally taken as 3.137 kg CO2 / kg.

[0061] The calculation formula of the carbon emission of the desulfurization is as follows:

[0062] Desulfurization CO2 emission = coal consumption of the power plant × sulfur content of coal × 44 / 32 × desulfurization efficiency

[0063]

[0064] Among them, S_emission is the carbon emission of the desulfurization process in the t time period, S_rate is the sulfur content of coal (%), and deSO2_eff is the desulfurization efficiency (usually 99%).

[0065] Optionally, the method further includes:

[0066] determining a first total amount according to the power plant construction data, the first total amount being a sum of the carbon emission of the manufacturing of the power generation equipment, the carbon emission of the construction of the power plant, the carbon emission of the waste treatment, and the carbon emission of the demolition of the power plant;

[0067] determining a first annual average carbon emission according to the first total amount and the life cycle of the power plant;

[0068] ​According to the first average annual carbon emission and the average annual utilization hours, a second carbon emission in the first preset time period is determined, wherein the average annual utilization hours is a ratio of the annual power generation of the target power plant to the installed capacity.

[0069] Specifically, the first total amount can be understood as the sum of the carbon emissions of manufacturing power generation equipment, constructing the power plant, waste treatment in the process of decommissioning the power plant, and dismantling the power plant. The power plant life cycle can be a preset value determined according to various factors and requirements of the power plant, and the equipment life can be consistent with the power plant life.

[0070] The first average annual carbon emission can be a ratio of the first total amount and the power plant life cycle. It should be noted that the first average annual carbon emission is not the carbon emission in the first year, and the "first" here is not a limitation on the year.

[0071] The average annual utilization hours can be the utilization hours of the previous year. From the perspective of post-analysis, the carbon emission of this part can be corrected and adjusted after each year ends. The first average annual carbon emission is evenly distributed to the first preset time period according to the average annual utilization hours.

[0072] In this embodiment, the method for generating the carbon emission information can determine a first total amount according to the power plant construction data, the first total amount being the sum of the carbon emissions of manufacturing power generation equipment, constructing the power plant, waste treatment, and dismantling the power plant. According to the first total amount and the power plant life cycle, a first average annual carbon emission is determined, and according to the first average annual carbon emission and the average annual utilization hours, a second carbon emission in the first preset time period is determined, wherein the average annual utilization hours is a ratio of the annual power generation of the target power plant to the installed capacity. Therefore, the carbon emissions of manufacturing power generation equipment, constructing the power plant, waste treatment, and dismantling the power plant can be evenly distributed year by year according to the power plant life, and then evenly distributed to the first preset time period according to the average annual utilization hours in the annual scale, thereby improving the accuracy of calculating the carbon footprint of the target power plant.

[0073] Optionally, the carbon emission of dismantling the power plant is equal to the sum of the oil carbon emission and the electricity carbon emission, the oil carbon emission is equal to the product of the oil carbon emission intensity and the oil consumption, and the electricity carbon emission is equal to the product of the implicit carbon emission factor and the electricity consumption.

[0074] For example, the calculation formula of the carbon emission of dismantling the power plant is as follows:

[0075] EM waste= oil_den * oil_retired + elec_den * elec_retired

[0076] wherein EM waste is the carbon emission of the decommissioned power plant, oil_den is the carbon emission intensity of the oil used by the decommissioned power plant, oil_retired is the oil consumption of the decommissioned power plant, elec_den is the carbon emission factor, and elec_retired is the electricity consumption of the decommissioned power plant.

[0077] Optionally, the target power plant comprises a boiler, a steam turbine, a generator, and auxiliary machinery, and the carbon emission of the manufactured power generation equipment comprises at least one of:

[0078] the carbon emission of the boiler, the carbon emission of the steam turbine, the carbon emission of the generator, and the carbon emission of the auxiliary machinery.

[0079] The carbon emission of the manufactured power plant comprises the carbon emission of the steel and cement used for construction of the power plant.

[0080] Specifically, the boiler, the steam turbine, the generator, and the auxiliary machinery are power generation equipment of the target power plant, and the auxiliary machinery can comprise a coal mill, an air blower, a water vapor circulation device, and environmental protection equipment.

[0081] For example, the carbon emission of the manufactured power generation equipment and the carbon emission of the manufactured power plant are calculated according to the following formulas:

[0082] EM equipment + EM construct = CO2_boiler + CO2_turbine + CO2_generator +

[0083] CO2_auxiliary + CO2_cemsteel + CO2_construct

[0084] wherein CO2_boiler is the carbon emission of the boiler, CO2_turbine is the carbon emission of the steam turbine, CO2_generator is the carbon emission of the generator, CO2_auxiliary is the carbon emission of the auxiliary machinery, and CO2_cemsteel is the carbon emission of the steel and cement used for construction of the power plant.

[0085] Optionally, the coal mining and transportation data comprises at least two coal mining and transportation sub-data, and the at least two coal mining and transportation sub-data correspond to at least two batches one by one.

[0086] The coal mining and transportation sub-data includes the amount of incoming coal of each batch, the carbon emission intensity of coal transportation, and the carbon emission intensity of coal production, and the third carbon emission amount in the first preset time period is determined according to the coal mining and transportation data, including:

[0087] A second total amount is determined according to the amount of incoming coal, the carbon emission intensity of coal transportation, and the carbon emission intensity of coal production of the at least two batches, and the second total amount is the sum of the carbon emission amounts of the at least two batches of coal mining and transportation;

[0088] A second annual carbon emission amount is determined according to the second total amount and the life cycle of the power plant;

[0089] The third carbon emission amount in the first preset time period is determined according to the second annual carbon emission amount and the annual average utilization hours, wherein the annual average utilization hours is the ratio of the annual power generation amount to the installed capacity of the target power plant.

[0090] Specifically, the above-mentioned coal mining and transportation sub-data can be the relevant data of the incoming coal of each batch, and the second annual carbon emission amount can be the ratio of the second total amount to the life cycle of the power plant. It should be noted that the second annual carbon emission amount does not refer to the carbon emission amount in the second year, and the "second" here is not a limitation on the year.

[0091] The annual average utilization hours can be the utilization hours of the previous year, and the carbon emission of this part can be corrected and adjusted after each year ends from the perspective of post-analysis. The first annual carbon emission amount is evenly distributed to the first preset time period according to the annual average utilization hours.

[0092] It should be noted that, in the case of data accounting conditions, the carbon emission of the coal mining and transportation link is calculated based on the mining method and transportation method of the coal source of each batch of incoming coal. In the case where the batch cannot be determined, the minimum determinable time period can be taken as the average value, and the calculation is performed according to the coal consumption of the coal-fired power unit and scaled to the scale of the first preset time period.

[0093] For example, the calculation formula of the second total amount is as follows:

[0094]

[0095] Wherein, EMtrans is the total amount of implicit carbon emission of incoming coal, CO2_coal_pden n is the carbon emission intensity of coal production of the nth batch, CO2_coal_tden n is the carbon emission intensity of coal transportation of the nth batch, coal_input nis the amount of incoming coal for the nth batch, N is the total number of batches, and the loss of incoming coal is not considered for the time being. The emission factor of unit coal production is 0.07 t CO2 / tce, which can be used as the default data of carbon emission intensity of coal production.

[0096] As a specific embodiment, the carbon emission information generation method can be applied to a coal-fired power plant power generation carbon footprint near real-time accounting model, Figure 2 is a flow diagram of an accounting model provided by an embodiment of the present application, as Figure 2 shown:

[0097] In order to more accurately, systematically and comprehensively account for the carbon footprint of coal-fired generating units, the present application proposes a coal-fired power plant power generation carbon footprint near real-time accounting model, LCA_CUFP, which can output the carbon footprint of coal-fired power generation enterprises in near real time. The LCA_CUFP model selects a method based on process analysis (PA) to model the carbon footprint of coal-fired generating units in production and operation.

[0098] The model is mainly for pure condensing power generation coal-fired generating units. Firstly, the boundary of carbon footprint accounting of coal-fired generating units is defined, and the time granularity of carbon emission accounting of different links of coal-fired power generation is defined. At the same time, the model can select to use input coal-fired generating unit production data or directly use default data, and through modeling and accounting of carbon emissions of processes such as construction of coal-fired generating units, coal mining and transportation, coal-fired power generation, and retirement of coal-fired power plants, the carbon footprint intensity of coal-fired generating units is output.

[0099] Among them, the carbon footprint accounting boundary is defined, Figure 3 is a schematic diagram of a carbon footprint accounting boundary provided by an embodiment of the present application, as Figure 3 shown: Taking a coal-fired power plant as the target object, according to the carbon footprint accounting standard, the scope of emission (direct carbon emission) is mainly the combustion link of coal in the process of coal-fired power generation and the desulfurization carbon emission generated by using gypsum for desulfurization; the scope of emission (indirect carbon emission) mainly includes the carbon emission of the user to provide electricity and heat, and the coal-fired power plant as an energy producer to produce electricity and heat, generally produces electricity and heat by itself, and the external power line is used as a backup to ensure the production and operation, the annual use is uncertain and the electricity is very small, which is not the focus of the present model; the scope of emission (indirect carbon emission between upstream and downstream) mainly includes the carbon emission of the process links such as equipment manufacturing, construction, coal transportation, and coal waste and retirement of coal-fired power plants.

[0100] Therefore, the formula for calculating the total amount of carbon footprint is as follows:

[0101]

[0102] Among them, EMlca is the total carbon footprint in the time period T. Scope 1 emissions, is the carbon emission of coal-fired boiler in power generation process in time t, is the carbon emission of combustion-supporting oil, is the carbon emission of desulfurization process; Scope 3 emissions, EM equipment is the embodied carbon emission of power generation equipment manufacturing process, EM construct is the embodied carbon emission of coal-fired power plant construction process, EM trans is the carbon emission of coal mining, transportation and other processes, EM waste is the carbon emission of waste disposal and power plant decommissioning process.

[0103] In terms of time resolution of carbon footprint accounting, the time distribution of carbon emissions of different processes and the confirmation of emission responsibility have great differences. According to the correlation of emission responsibility, each component of the carbon footprint will be allocated and confirmed according to certain rules. The time scale of the carbon footprint output can be set to 15 minutes, which is consistent with the time period of the intraday spot trading quotation of the electricity market.

[0104] It should be noted that the carbon emissions of the power generation equipment manufacturing process and the power plant construction process belong to the upstream centralized emissions for coal-fired power generation enterprises. In terms of emission responsibility division, the centralized emissions are allocated according to the equipment life (the main equipment in the model is set to be consistent with the life of the power plant) and the life of the power plant year by year, and then the annual average utilization hours (the utilization hours of the last year can be used, and based on the perspective of post-analysis, the carbon emissions of this part can be corrected and adjusted after each year ends) are allocated to the 15-minute time period of the operation of the coal-fired unit.

[0105] The model can cover the carbon footprint calculation of the power plant under the following operating conditions, Figure 4a is a schematic diagram of a conventional operating condition of a power plant provided by an embodiment of the present application, as Figure 4a shown, in the conventional operating condition, the boiler is maintained for stable combustion, the unit load is generally maintained at not less than 50% design load, and the output load is adjusted according to the dispatching instruction and the power plant production plan requirement; Figure 4b is a schematic diagram of a frequent start-stop operating condition of a power plant provided by an embodiment of the present application, as Figure 4b shown, in the frequent start-stop operating condition, the unit is mainly stopped in response to the situation that the new energy such as wind and light is large and the thermal power low-load condition is difficult to stabilize, and is started to peak when needed; Figure 4c is a schematic diagram of a deep peak regulation operating condition of a power plant provided by an embodiment of the present application, as Figure 4c shown, in the deep peak regulation operating condition, the unit is mainly operated at low load in response to the system dispatching demand, and is quickly started to peak when needed to play the role of system regulation.
