Abstract
Description
Technical Field
[0001] The present application relates to the technical field of carbon quota scheduling, and in particular to a carbon quota scheduling method, device, equipment, storage medium and program product. Background Art
[0002] With the large-scale grid connection of renewable energy power generation, green electricity (electricity with carbon dioxide emissions approaching zero or zero during the production process) is gradually becoming an important source of electricity supply. Especially for regions with unbalanced distribution of production capacity and energy consumption structure, cross-regional green electricity trading will become an inevitable choice for consuming renewable energy and promoting carbon emission reduction in the future. At present, there is a general consensus on the carbon emission reduction benefits of consuming green electricity, but there is currently no clear accounting and measurement method for how much carbon emissions are equivalent to cross-regional green electricity consumption.
[0003] In the existing technology, it is usually agreed that green electricity does not produce carbon emissions during electricity trading. When calculating electricity carbon emissions, the green electricity consumption is deducted from the total electricity consumption, and then multiplied by the average carbon emission factor of the regional power grid to obtain the electricity carbon emissions. However, the total amount of green electricity in the region has been deducted when calculating the average carbon emission factor of the regional power grid, which will lead to the problem of duplicate calculation. When the carbon emission calculation involves multiple different regions and power generation entities, the calculated carbon emissions are less accurate, which affects the reasonable scheduling of carbon quotas and results in poor energy conservation and emission reduction effects.

[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0050] The carbon quota scheduling method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. Among them, the terminal 102 can be, but is not limited to, sensors and data acquisition devices in various power systems, such as carbon footprint data acquisition devices for measuring or tracking electricity users, carbon trading data recording platforms, power generation data acquisition devices, power consumption data acquisition devices, various types of electric energy meters and power monitoring systems, etc. The server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.
[0051] In an exemplary embodiment, Figure 2 As shown, a carbon quota scheduling method is provided, which is applied to Figure 1 The application environment in is taken as an example to illustrate, including the following steps 202 to 206.
[0052] in:
[0053] Step 202, obtaining the historical carbon emission data and historical electricity consumption-clearing power data of the target electricity users, and obtaining the historical power generation-clearing power data of the target power generation entities; wherein the target power generation entities include renewable energy power generation entities and non-renewable energy power generation entities.
[0054] Among them, the target electricity user refers to the recipient of electricity resources when transferring electricity resources, which can be a power company or an end user. The target power generation entity refers to the power resource provider when transferring electricity resources, that is, the entity used to produce electric energy, which can be a generator set, such as a thermal power unit, a wind power unit, etc. The problem of difficult storage of electricity resources can be solved by timely transferring the generated electricity resources to the electricity user through the power generation entity, so that the production and use of the power system can be completed at the same time, and the utilization rate of electricity resources can be improved. Historical carbon emission data refers to the electricity data transferred when all the electricity resources generated by the power generation entity are transferred to the power user. Renewable energy power generation entity refers to the power generation entity that uses renewable energy to generate electricity, such as wind, hydropower and solar power generation entities. Non-renewable energy power generation entity refers to the power generation entity that uses non-renewable energy to generate electricity, such as the power generation entity that uses coal, natural gas, oil or nuclear energy to generate electricity.
[0055] Exemplarily, the historical carbon emission data, historical electricity consumption-clearing power data and historical power generation-clearing power data of the target electricity user can be obtained through data exchange with the target electricity user, target power generation or carbon emission data provider through data collection tools or data access protocols. For example, the historical electricity consumption data of the target subject can be obtained through the data of electricity meters, smart meters or power providers, the historical carbon emission data can be obtained from energy suppliers or carbon emission data providers, and the historical power generation-clearing power data can be obtained from electricity market data or directly from the target power generation subject.
[0056] Step 204, determine the equivalent carbon emissions of the target electricity user based on the historical power generation-clearing power data and historical power consumption-clearing power data corresponding to the renewable energy power generation entity, and determine the carbon quota transfer data when scheduling the target carbon quota based on the equivalent carbon emissions.
[0057] Among them, equivalent carbon emissions refer to the standardization of all carbon emissions of the subject that emits carbon, so that it can be better compared with other subjects or measure the overall impact of the subject on the greenhouse effect. It is the net carbon emissions of the target electricity user taking into account the emission reduction benefits after the use of renewable energy. Carbon quota represents the carbon emission quota, that is, the total amount of greenhouse gas emissions allowed. Through the setting of carbon quotas, greenhouse gas emissions can be restricted to achieve environmental protection. Target carbon quota refers to the target carbon quota after carbon quota scheduling determined based on equivalent carbon emissions. Carbon quota transfer data refers to data that records and tracks carbon emission rights transactions and transfers, which may include data such as emission subjects and emission quantities.
[0058] For example, the equivalent carbon emissions of the target electricity user can be determined based on the historical power generation and clearing data of renewable energy power generation entities, and information such as power consumption, power generation, and energy sources can be obtained; for different power sources, the corresponding carbon emission factors can be used to calculate the carbon emissions of electricity use. Fossil fuel power generation usually has higher carbon emissions, while renewable energy power generation has very low or approximately zero carbon emissions. Therefore, fossil fuels and renewable energy have different carbon emission factors. Comparing the carbon emission factors of renewable energy with those of traditional energy can obtain the carbon emission reduction benefits of renewable energy. Combining the carbon emissions corresponding to power consumption and the carbon emission reduction benefits corresponding to renewable energy can obtain the equivalent carbon emissions of the target electricity user.
[0059] Step 206: Schedule the target carbon quota according to the carbon quota transfer data.
[0060] Exemplarily, the carbon quota can be scheduled according to the obtained carbon quota transfer data, so that the carbon quota after scheduling is the target carbon quota. Taking the above example as an example, the carbon quota is scheduled between the carbon quota transfer-out party and the carbon quota transfer-in party according to the carbon quota transfer data, so that the carbon quota of the carbon quota transfer-out party or the carbon quota transfer-in party after scheduling is the target carbon quota.
[0061] In the above-mentioned carbon quota scheduling method, the historical carbon emission data and historical electricity-clearing power data of the target electricity user are obtained, and the historical power generation-clearing power data of the target power generation subject is obtained; wherein, the target power generation subject includes renewable energy power generation subject and non-renewable energy power generation subject; the carbon emission situation of the target electricity user and the source of the electricity used can be understood, and the carbon footprint can be quantified; the equivalent carbon emissions of the target electricity user are determined according to the historical power generation-clearing power data and historical electricity-clearing power data corresponding to the renewable energy power generation subject, and the carbon quota transfer data when scheduling the target carbon quota is determined according to the equivalent carbon emissions; the actual carbon emissions of the electricity user can be more accurately reflected, the emission reduction benefits brought by the use of renewable energy by the electricity user can be quantified, and the efficient use and precise scheduling of sustainable energy can be promoted; the target carbon quota can be scheduled according to the carbon quota transfer data, and the carbon quota scheduling can be flexibly realized, the reliability of the carbon quota scheduling can be improved, and the energy-saving and emission reduction measures can be made more precise and effective.
[0062] In an exemplary embodiment, the equivalent carbon emissions of a target electricity user are determined based on historical power generation-clearing power data and historical power consumption-clearing power data corresponding to the renewable energy power generation subject, including: determining the total carbon emissions of the target electricity user within a preset historical period; determining the corresponding difference in carbon emissions reduction when the target electricity user consumes renewable energy within the preset historical period based on the renewable energy identification information in the historical power consumption-clearing power data; and determining the target carbon emissions of the target electricity user based on the difference between the total carbon emissions and the carbon emissions.
[0063] Among them, total carbon emissions refer to the sum of all greenhouse gas emissions generated by the target electricity user, which can be expressed in parameters such as carbon dioxide equivalent. Renewable energy identification information refers to the identification information of energy, electricity or fuel, which is used to indicate that the energy is generated from a renewable energy source. It is usually contained in carriers such as electricity labels or electricity certificates. It can also include information such as the percentage of renewable energy in energy products and the geographical location of renewable energy resources, such as the location of wind farms or solar panels. The corresponding reduction in carbon emissions when consuming renewable energy refers to the carbon emissions reduced by the electricity user due to the use of renewable energy.
[0064] Exemplarily, the target electricity user's electricity source and electricity consumption can be determined, the corresponding carbon emission coefficient can be determined according to the electricity source, and then the carbon emission coefficient can be multiplied by the electricity consumption to obtain the total carbon emissions of the target electricity user in the preset historical period. The corresponding reduction in carbon emissions when the target electricity user consumes renewable energy in the preset historical period can be determined based on the renewable energy identification information in the historical electricity consumption clearing power data, and the carbon emission factor related to the non-renewable energy in the carbon quota to be scheduled area can be used to calculate the carbon emissions of electricity consumption in the carbon quota to be scheduled area without renewable energy; and based on the renewable energy identification information in the electricity consumption clearing power data, the proportion of renewable energy is determined, and the corresponding carbon emission reduction is calculated, and the carbon emissions of non-renewable energy are added to the carbon emission reduction of renewable energy to obtain the carbon emissions reduced by the target electricity user in the preset historical period by consuming renewable energy.
[0065] In an exemplary embodiment, the total carbon emissions of a target electricity user within a preset historical period are determined, including: obtaining the total power generation of each non-renewable energy power generation entity in the carbon quota to be scheduled area, and obtaining the total carbon emissions of the carbon quota to be scheduled area; determining the average carbon emission factor of the carbon quota to be scheduled area according to the ratio of total carbon emissions to total power generation, and determining the total carbon emissions of the target electricity user according to the average carbon emission factor and the total electricity consumed by the target electricity user within the preset historical period; wherein the average carbon emission factor is used to characterize the carbon emissions generated when the carbon quota to be scheduled area produces and consumes electricity.
[0066] Among them, the average carbon emission factor of the carbon quota to be scheduled area refers to the ratio between the total carbon emissions and the total energy consumption generated in the carbon quota to be scheduled area within a specific time period.
[0067] Exemplarily, the average carbon emission factor of the area to be scheduled for carbon quota is determined based on the ratio of total carbon emissions to total power generation, and the total carbon emissions of the target power user are obtained by multiplying the average carbon emission factor by the total electricity consumed by the target power user in a preset historical period. The total carbon emissions of the target power user obtained by multiplying the average carbon emission factor by the total electricity consumed by the target power user in a preset historical period is an estimated value of the actual total carbon emissions, and this value can reflect the carbon emission contribution of the target power user.
[0068] In an exemplary embodiment, the difference in carbon emissions corresponding to the reduction when a target electricity user consumes renewable energy within a preset historical period is determined based on renewable energy identification information in historical electricity consumption and clearing power data; including: determining the marginal carbon emission factor of the carbon quota to be scheduled area based on the carbon emissions generated by non-renewable energy power generation entities in the carbon quota to be scheduled area, the total power generation of non-renewable energy power and the total power generation of renewable energy power, the marginal carbon emission factor is used to characterize the carbon emissions corresponding to the increase in power resources of the target electricity user in the carbon quota to be scheduled area; obtaining the renewable energy power clearing amount of the target electricity user within the preset historical period, and determining the difference in carbon emissions corresponding to the reduction when consuming renewable energy based on the marginal carbon emission factor and the renewable energy power clearing amount.
[0069] Among them, the marginal carbon emission factor refers to the carbon emissions corresponding to an additional unit of electricity under specific conditions. It can be used to measure the impact of an increase or decrease in electricity in the power system on carbon emissions. The size of the marginal emission factor is related to factors such as the source of electricity and electricity demand. For example, the increase in renewable energy can reduce the marginal emission factor. Renewable energy power clearing refers to the power supply from renewable energy in the power market.
[0070] For example, the marginal carbon emission factor of the carbon quota to be dispatched area can be obtained by simulating the change of carbon emissions under a specific electricity consumption scenario using an energy model or a power system model based on the energy supply structure of the carbon quota to be dispatched area, or by calculation, for example, using the total power generation as the weight, calculating the weighted average of the carbon emission factors of each non-renewable energy power generation entity in the carbon quota to be dispatched area, and using the average as the marginal carbon emission factor. Multiply the marginal carbon emission factor by the amount of renewable energy power cleared to obtain the amount of carbon emissions reduced by the target power user due to the consumption of renewable energy.
[0071] In an exemplary embodiment, in one of the embodiments, the marginal carbon emission factor of the carbon quota to be scheduled area is determined based on the carbon emissions generated by the non-renewable energy power generation entities in the carbon quota to be scheduled area, the total power generation of non-renewable energy electricity and the total power generation of renewable energy electricity, including: obtaining the total power generation of the non-renewable energy power generation entities in the carbon quota to be scheduled area within a preset historical period, the total amount of fuel used for power generation and the carbon emission factors corresponding to each component of the fuel; determining the actual low heating value of each non-renewable energy power generation entity based on the total power generation, the total amount of fuel and the carbon emission factor, and the actual low heating value is used to characterize the actual available electricity generated by the fuel; using the total power generation as the weight, calculating the weighted average of the carbon emission factors of each non-renewable energy power generation entity in the carbon quota to be scheduled area, and obtaining the marginal carbon emission factor of the carbon quota to be scheduled area.
[0072] Among them, the actual low calorific value refers to the heat released by the fuel during the actual combustion process. When calculating the actual low calorific value, it is necessary to consider the water content in the fuel and the generation and condensation of water vapor during the combustion process. For the same fuel with the same composition, the actual low calorific value is usually lower than the theoretical low calorific value. The actual available electricity refers to the amount of electricity generated by the combustion of fuel, which can be finally put into the power system for use by electricity users after all losses and wastes. The weighted average of the carbon emission factors refers to the average value calculated by considering the weights of different carbon emission factors, which can reflect the total carbon emissions of the power generation entity or the area where the carbon quota is to be dispatched.
[0073] For example, the total power generation of non-renewable energy power generation entities in the carbon quota to be dispatched area within the preset historical period, the total amount of fuel used for power generation, and the carbon emission factor of each fuel can be directly obtained from the database of the power generation entity, or calculated from the fuel used for power generation and related parameters of the fuel. The actual low calorific value can be calculated based on the total amount of fuel, the composition of the fuel, and the chemical reaction of each element during complete combustion, or it can be obtained by calculating the quotient of the total power generation and the total amount of fuel.
[0074] In an exemplary embodiment, the actual low heating value of each non-renewable energy power generation entity is determined based on the total power generation, the total fuel amount and the carbon emission factor, including: obtaining the fuel data consumed by each non-renewable energy power generation entity to generate non-renewable energy power; wherein the fuel data includes the components of the fuel, the total mass, the mass proportion of each component and the calorific value data of each component; determining the theoretical total low heating value corresponding to the non-renewable energy power generated by each power generation entity in the carbon quota to be scheduled area based on the fuel data; determining the actual low heating value of each non-renewable energy power generation entity based on the theoretical total low heating value and the heat loss of each non-renewable energy power generation entity during the energy conversion and transmission process.
[0075] Among them, fuel data refers to data such as fuel type, source, consumption and composition. The fuel consumed to generate non-renewable energy electricity can include coal, natural gas, oil, nuclear fuel and biomass fuel, etc. Calorific value data is called calorific value data, which refers to the energy contained in unit mass or unit volume of fuel. Different fuels usually have different calorific values, which are related to factors such as the chemical composition and energy density of the fuel. The theoretical lower calorific value is the heat released by the fuel when it is completely burned. It characterizes the heat generation of the fuel during the combustion process without considering water vapor condensation and heat recovery, and is usually determined based on the chemical composition of the fuel.
[0076] For example, the fuel data consumed by each power generation entity to generate non-renewable energy power can be obtained by monitoring the energy usage of the power generation entity or directly exchanging data with the power generation entity; the sum of the theoretical low calorific value of each power generation entity that generates non-renewable energy power in the carbon quota to be dispatched area can be calculated based on the total mass of the fuel, the mass proportion of each fuel and the calorific value data, and the theoretical low calorific value of each fuel can be obtained by multiplying the total mass of each fuel by the calorific value of the fuel, and then calculating the sum of the theoretical low calorific value of each fuel of each power generation entity to obtain the total theoretical low calorific value of non-renewable energy power generated in the carbon quota to be dispatched area. According to the energy flow path of each power generation entity in the energy conversion and transmission process, and the energy loss points and energy loss types that may exist on the path, such as resistance, heat loss or mechanical loss generated by fuel combustion, generator efficiency, transmission lines, transformers, converters and other links, the energy loss is quantified according to the energy loss point and loss type, and then the theoretical low calorific value is subtracted from the energy loss to obtain the actual low calorific value of each power generation entity.
[0077] In an exemplary embodiment, a carbon quota scheduling method is provided, where the emission reduction contribution of one green certificate (i.e., 1000KW·h green electricity) generated by renewable energy power generation can be equivalent to the carbon emissions generated by renewable energy power generation, such as Figure 3 As shown, the method comprises the following steps:
[0078] Step 302: Obtain the historical carbon emission data and historical electricity consumption-clearing power data of the target electricity user, and obtain the historical power generation-clearing power data of the target power generation entity.
[0079] The historical electricity consumption clearing data may include the number of green certificates purchased by the target electricity user. The green certificates may be purchased by the target from power generation entities within or outside the carbon quota to be dispatched area.
[0080] Step 304: Calculate the marginal carbon emission factor per unit electricity volume in the region based on the carbon emissions generated by power generation entities in the carbon quota to be dispatched region, non-renewable energy electricity, and renewable energy electricity.
[0081] Purchasing one green certificate is equivalent to purchasing 1000kWh of green electricity. Its essence is a kind of electricity substitution. The emission reduction it produces is not a linear emission reduction effect, but a nonlinear emission reduction effect, and there is a marginal decreasing effect. Therefore, it is necessary to determine the actual emission reduction of green electricity in different regions. The specific calculation method is as follows:
[0082] Assume that the carbon emissions generated by the regional power industry are Q CO2 , the regional thermal power supply is E f , the regional green electricity supply is E g, then the emission factor per unit of electricity in the region is:
[0083]
[0084] Let θ represent the proportion of renewable energy generation, then
[0085]
[0086] It can be seen that for every one percentage point increase in the proportion of green electricity, the change in the regional electricity carbon emission factor is the derivative of the above formula with respect to θ:
[0087]
[0088] Solving the above ordinary differential equation, we can get:
[0089]
[0090] When θ = 0, it means that 100% of the electricity supply in the carbon quota dispatch area is thermal power, so the constant e can be determined c for:
[0091]
[0092] This constant can be expressed as the carbon emission per unit of electricity of the most advanced thermal power units, or as the average carbon emission per unit of regional thermal power. In addition, it can be seen that when the proportion of renewable energy increases, the carbon efficiency of thermal power supply will decrease accordingly. Then the carbon emission reduction increased by green electricity should actually be equal to the emission reduction corresponding to green electricity minus the increase caused by the reduction in thermal power efficiency.
[0093] Assume that the original green electricity ratio in region A is Increase the proportion of green electricity to Keeping the thermal power generation unchanged, the change in the unit carbon emission factor of regional thermal power is:
[0094]
[0095] Therefore, the change in carbon emissions from thermal power caused by the change in green electricity is:
[0096]
[0097] The direct carbon emission change caused by the change of green electricity is:
[0098]
[0099] The change in regional carbon emissions caused by changes in green electricity is:
[0100] C=C1+C2
[0101] The carbon emission reduction for every additional 1MWh of green electricity in the region is:
[0102]
[0103] This indicates the carbon emission reduction brought about by each additional green certificate generated in region A.
[0104] From the above calculation process, it can be seen that the main factor affecting the marginal carbon emission factor is the proportion of green electricity. In order to demonstrate the above method more clearly, the marginal carbon emission reduction of two carbon quota dispatching areas with different electricity consumption structures is calculated separately: assuming that the total electricity consumption of regions A and B is 1000MWh, region A has 500MWh of thermal power and 500MWh of green power, then green electricity accounts for 50%; region A has 900MWh of thermal power and 100MWh of green power, then green electricity accounts for 10%. If both regions increase the green electricity by 200MW, it can be seen that the green electricity in region A actually increased by 8.3% percentage points, while that in region B increased by 15%, and the marginal carbon emission reduction brought about is different, and the marginal carbon emission reduction in region B is much greater than that in region A.
[0105] Step 306: Calculate the carbon emissions reduction of electricity users in the carbon quota to be dispatched area due to consumption of renewable energy electricity based on the marginal carbon emission factor, and determine the carbon quota transfer data when dispatching the target carbon quota based on the reduced carbon emissions.
[0106] If the power user j in the power system area i obtains the green certificate quantity G generated by the power system area A through cross-regional green certificate transactions k , then the carbon emissions that can be offset by purchasing this part of the green certificate is:
[0107] GEC j =G k GF(A)
[0108] In the above formula, GEC j represents the carbon offset amount of green certificate transaction of power user j, and GF(A) is the carbon offset factor of green certificate of regional power grid A. The carbon emissions that can be offset by the above green certificate can be used as the carbon quota transfer data of the target power user or the calculation basis of carbon quota transfer data to obtain carbon quota transfer data.
[0109] Step 308: Scheduling the target carbon quota according to the carbon quota transfer data.
