Description

Technical Field

[0001] This invention belongs to the field of data processing technology, specifically relating to a method and apparatus for determining the carbon reduction of a pumped storage power station. Background Technology

[0002] Hydropower, as a low-carbon energy source, has a much lower greenhouse gas emission intensity than thermal power. After being transported to the target power grid, hydropower partially replaces thermal power within the grid, thereby reducing greenhouse gas emissions from the electricity generated and mitigating environmental pollution.

[0003] In existing schemes, the carbon reduction of pumped storage power plants relative to thermal power plants is usually determined by the electricity consumption and operating costs of the pumped storage power plants during power generation. However, due to environmental and other factors, the amount of carbon emissions can change, resulting in low accuracy when determining the carbon reduction directly based on electricity consumption and operating costs. Summary of the Invention

Based on the first and second carbon emissions, the carbon reduction of the target pumped-storage power station relative to the reference thermal power station is determined. This improves the accuracy of carbon reduction determination by using the first carbon emission and the second carbon emission of the reference thermal power station to determine the carbon reduction, based on the operating information, energy consumption information, water level information, and environmental information of the target pumped-storage power station.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0067] To better understand the method for determining the carbon reduction of a pumped-storage power station provided in this application, a brief introduction to existing methods for determining the carbon reduction of pumped-storage power stations is given below. In existing solutions, the carbon reduction is typically determined by combining the increase in carbon emissions from the pumped-storage power station with historical data on carbon emission reductions relative to traditional fossil fuel power plants. This approach fails to comprehensively consider environmental factors during power generation, resulting in low accuracy of the obtained carbon reduction.

[0068] To address the aforementioned issues, this application provides a method for determining the carbon reduction of a pumped storage power station. This method can determine a first carbon emission based on the target pumped storage power station's operational information, energy consumption information, water level information, and environmental information. The carbon reduction is then determined using this first carbon emission and a second carbon emission from a reference thermal power station, thus improving the accuracy of carbon reduction determination.

[0069] Please see Figure 1 , Figure 1 This is a flowchart illustrating a method for determining the carbon reduction of a pumped storage power station, provided as an embodiment of this application. Figure 1 As shown, the method includes:

[0070] 101. Determine the first reference carbon emission based on the operating information and energy consumption information of the target pumped storage power station when it generates the target amount of electricity.

[0071] Among them, the target pumped storage power station can be a pumped storage power station for which carbon reduction calculations are required. A pumped storage power station can be understood as a hydroelectric power station that uses electricity generated during off-peak hours to pump water to an upper reservoir and then releases the water to a lower reservoir to generate electricity during peak hours. It is also known as an energy storage hydroelectric power station. It can convert excess electricity generated when the grid load is low into high-value electricity generated during peak hours. It is also suitable for frequency and phase regulation, stabilizing the frequency and voltage of the power system, and is suitable for emergency backup. It can also improve the efficiency of thermal power plants and nuclear power plants in the system. The target pumped storage power station can include pure pumped storage power stations and hybrid pumped storage power stations. Pure pumped storage power stations can be understood as having no or only a small amount of natural water entering the upper reservoir (to compensate for evaporation and seepage losses), while the water body, as the energy carrier, is basically kept at a fixed quantity and is reused between the upper and lower reservoirs within a cycle. The entire plant is equipped with pumped storage units, whose main functions are peak shaving and valley filling, and system emergency backup, but not conventional power generation or comprehensive utilization.

[0072] A hybrid pumped-storage power station can be understood as a reservoir with natural runoff inflow, where the inflow rate is sufficient to install conventional hydro-turbine generator units to handle the system load. Therefore, the units installed in its power plant consist of both conventional hydro-turbine generator units and pumped-storage units. The power generation of a hybrid pumped-storage power station also comprises two parts: pumped-storage power generation and natural runoff power generation.

[0073] The target power output can be a pre-set value. Operational information can be understood as the power conversion rate of the pumped-storage hydroelectric power station when generating the target power output. Specifically, it can be understood as the efficiency of converting electrical energy into the potential energy of water, and then converting that potential energy back into electrical energy. The power conversion rate can be used to calculate energy consumption, and consequently, carbon reduction. Energy consumption information can include time information and power consumption information. Time information can be understood as the time period during which electrical energy is used for potential energy storage; the maximum power output and electricity price will differ in different time periods. For example, even during the same off-peak electricity load period, the power output and electricity price will vary.

[0074] Sub-reference carbon emissions can be determined based on time information, power consumption information, and operation information. Finally, the determined sub-reference carbon emissions are merged to obtain the first reference carbon emissions, thereby improving the accuracy of the determination of the first reference carbon emissions.

[0075] 102. Obtain water level information and environmental information of the target pumped storage power station during power generation.

[0076] The water level information can be understood as the water level information of the target pumped-storage power station at multiple sampling times, while the environmental information may include the distribution information of aquatic organisms in the reservoir of the target pumped-storage power station. After being submerged, aquatic organisms will respire, thereby producing carbon emissions. Although the emissions produced by a single aquatic organism are relatively small, because aquatic organisms are usually distributed in large groups, the total amount produced is relatively high, thus increasing the carbon emissions during power generation.

[0077] 103. Determine the second reference carbon emission based on the water level information and environmental information.

[0078] The process involves determining the water level drop curve based on water level information, then determining the carbon emission curve of aquatic organisms based on the water level drop curve and environmental information, and finally determining the second reference carbon emission based on the carbon emission curve. The carbon emission curve can intuitively and accurately reflect the carbon emission at each sampling time, thereby improving the accuracy of determining the second reference carbon emission.

[0079] 104. Determine the first carbon emission amount when the target pumped storage power station generates the target amount of electricity based on the first reference carbon emission amount and the second reference carbon emission amount.

[0080] The first carbon emission can be determined by summing the first and second reference carbon emissions. Alternatively, the weights of the first and second reference carbon emissions during actual operation can be obtained separately to obtain the first and second weights. Finally, the first carbon emission is obtained by weighting the first and second reference carbon emissions using the first and second weights. The first and second weights can be set using empirical values ​​or historical data.

[0081] 105. Obtain the second carbon emissions when a reference thermal power plant generates the target amount of electricity.

[0082] The second carbon emission figure, which refers to the carbon emissions generated by a thermal power plant when producing the target amount of electricity, can be determined through statistical data. Specifically, it can be the average of the carbon emissions generated by multiple thermal power plants of similar size when producing the target amount of electricity, which can be used as the second carbon emission figure. Of course, the second carbon emission figure can also be obtained through other methods, which are not specifically limited here.

[0083] 106. Based on the first carbon emission amount and the second carbon emission amount, determine the carbon reduction amount of the target pumped storage power station relative to the reference thermal power station.

[0084] The difference between the second carbon emission and the first carbon emission can be defined as the carbon reduction.

[0085] In this example, a first reference carbon emission is determined based on the operating information and energy consumption information of the target pumped-storage power station when generating the target amount of electricity. Water level and environmental information of the target pumped-storage power station during power generation are obtained, and a second reference carbon emission is determined based on the water level and environmental information. The first carbon emission of the target pumped-storage power station when generating the target amount of electricity is determined based on the first and second reference carbon emissions. The second carbon emission of a reference thermal power station when generating the target amount of electricity is obtained. Based on the first and second carbon emissions, the carbon reduction of the target pumped-storage power station relative to the reference thermal power station is determined. This improves the accuracy of carbon reduction determination by using the first carbon emission and the second carbon emission of the reference thermal power station to determine the carbon reduction, based on the operating information, energy consumption information, water level information, and environmental information of the target pumped-storage power station.

[0086] In one possible implementation, a method for determining a first reference carbon emission based on operational information and energy consumption information of a target pumped-storage power station generating a target amount of electricity includes:

[0087] A1. Extract time information and power consumption information from the power consumption information;

[0088] A2. Determine the first sub-reference carbon emission based on the time information and power consumption information;

[0089] A3. Determine the second sub-reference carbon emission based on the aforementioned operational information;

[0090] A4. Obtain the first carbon emission impact factor corresponding to the first sub-reference carbon emission amount, and obtain the second carbon emission impact factor corresponding to the second sub-reference carbon emission amount;

[0091] A5. Based on the first carbon emission impact factor and the second carbon emission impact factor, the first sub-reference carbon emission and the second sub-reference carbon emission are fused to obtain the first reference carbon emission.

[0092] The operational information can be understood as the power conversion rate of the target pumped-storage hydroelectric power station when generating the target amount of electricity. Specifically, it can be understood as the efficiency of converting electrical energy into the potential energy of water, and then converting that potential energy back into electrical energy. The power conversion rate can be used to calculate energy consumption, and further, to calculate carbon reduction. Electricity consumption information can include time information and power consumption information. Time information can be understood as the time period during which electrical energy is used for potential energy storage; the maximum power output and electricity price will differ in different time periods. For example, even during the same off-peak electricity load period, the power output and price will vary.

[0093] The time information may include multiple running segments. Therefore, these multiple running segments are extracted from the time information. The power supply information is determined based on the power supply information of each running segment, and the sub-power consumption information of each running segment is determined based on the power consumption information. The carbon emissions of each running segment are determined based on the power supply information and the sub-power consumption information. Finally, the sum of the carbon emissions of each running segment is determined as the first sub-reference carbon emissions.

[0094] The power supply source information can include thermal power sources and clean energy sources, with clean energy sources including hydropower, wind power, and solar power. Each power supply source has a corresponding carbon emission factor. Therefore, multiple carbon emission factors and the power consumption information for each power supply source during operation can be obtained from the power supply source information. Finally, based on the power consumption information and the corresponding carbon emission factor for each power supply source, the carbon emissions of that power supply source are determined, and the sum of the carbon emissions of all power supply sources is determined as the carbon emissions for the corresponding time period.

[0095] The operational information includes the power generation conversion rate, which can be used to determine the corresponding carbon emissions. Specifically, a second sub-reference carbon emission can be determined based on a preset mapping relationship between the power generation conversion rate and carbon emissions.

[0096] Since electricity consumption information and operation information have their corresponding carbon emission impact factors, the carbon emission factor corresponding to the electricity consumption information can be determined as the first carbon emission impact factor, the carbon emission impact factor corresponding to the operation information can be determined as the second carbon emission impact factor, and finally the sum of the product of the first carbon emission impact factor and the first sub-reference carbon emission and the product of the second carbon emission impact factor and the second sub-reference carbon emission is determined as the first reference carbon emission.

[0097] In this example, the first sub-reference carbon emission and the second sub-reference carbon emission are determined by the power consumption information and the operation information, respectively. Finally, the first sub-reference carbon emission and the second sub-reference carbon emission are fused to obtain the first reference carbon emission, which improves the accuracy of the first reference carbon emission acquisition.

[0098] In one possible implementation, a method for determining a second reference carbon emission based on the water level information and environmental information includes:

[0099] B1. Determine the water level drop curve based on the water level information;

[0100] B2. Determine the carbon emission curve based on the environmental information and the water level drop curve;

[0101] B3. Determine the second reference carbon emission amount based on the carbon emission curve.

[0102] The water level information includes water level height values ​​and sampling time points. Based on these values, a water level decline curve can be constructed. Specifically, the curve is constructed with the horizontal axis representing time and the vertical axis representing water level height. After forming a discrete curve based on the water level height values ​​and sampling time points, the discrete points are smoothly connected using a preset weighted sequence according to the formula shown below to obtain the final water level decline curve.

[0103]

[0104] S in the formula i y represents the smoothing value used when smoothly connecting discrete points; i represents the i-th discrete point among multiple discrete points; m represents the width of the moving average window; y i ω represents the i-th discrete point among multiple discrete points; jThis represents the j-th preset weight in the preset weight sequence. The preset weight sequence can be determined by user input or by system default.

[0105] Based on environmental information, the distribution of aquatic organisms in the reservoir of the target pumped-storage power station can be determined, and the carbon emission distribution information can be derived from this information. Finally, the carbon emission curve can be determined based on the carbon emission distribution information and the water level drop curve. The carbon emission curve can be integrated over the power generation period to obtain the integral value, which is then used as the second reference carbon emission level.

[0106] In this example, a water level drop curve is constructed, and a carbon emission curve is determined based on the water level drop curve and environmental information. Finally, the carbon emission curve is integrated to obtain a second reference carbon emission, thus accurately obtaining the second reference carbon emission.

[0107] In one possible implementation, a method for determining a carbon emission curve based on the environmental information and the water level drop curve includes:

[0108] C1. Based on the environmental information, determine the distribution information of aquatic organisms in the reservoir of the target pumped storage power station;

[0109] C2. Determine the distribution information of carbon emissions from aquatic organisms based on the aforementioned aquatic organism distribution information;

[0110] C3. Based on the aquatic organism carbon emission distribution information and the water level drop curve, determine the carbon emission information at each water level drop sampling time.

[0111] C4. Construct the carbon emission curve based on the carbon emission information at each water level drop sampling time.

[0112] The aquatic organism distribution information may include regional information about the distribution of aquatic organisms and the types of aquatic organisms. The distribution area of ​​aquatic organisms may include information on their distribution along the height of the water surface and their distribution in a plane perpendicular to the water surface.

[0113] Carbon emissions at each water level can be determined based on information about the regional distribution and species of aquatic organisms, thus obtaining information on the distribution of carbon emissions from aquatic organisms. The carbon emissions at each water level can be understood as the total carbon emissions produced by aquatic organisms underwater.

[0114] As water levels drop, the amount of carbon produced by aquatic organisms through respiration decreases after they are submerged, thus reducing carbon emissions. This allows us to combine the water level drop curve with information on the distribution of aquatic organism carbon emissions to determine the carbon emissions at each sampling point during the water level drop. Finally, using the carbon emissions at each sampling point, we construct a carbon emissions curve with the horizontal axis representing time and the vertical axis representing carbon emissions. When aquatic organisms are not submerged, their respiration is normal and not due to water storage; therefore, it is not included in the overall carbon emissions calculation.

[0115] Specifically, the carbon emission curve can be constructed using the following formula:

[0116]

[0117] Where cm = sm * hm, sm is the horizontal area of ​​region m, hm is the water level of region m at time t, and m is the number of regions.

[0118] Where F(t) is the carbon emission at time t, y1 is the carbon emission of the first aquatic organism, y2 is the carbon emission of the second aquatic organism, yn is the carbon emission of the nth aquatic organism, c1 is the area of ​​the first region (which includes water level height, a variable), c2 is the area of ​​the second region, cm is the area of ​​the mth region, k11 is the average distribution information of the first aquatic organism in the first region, k12 is the average distribution information of the second aquatic organism in the first region, k1n is the average distribution information of the nth aquatic organism in the first region, km1 is the average distribution information of the first aquatic organism in the first region, km2 is the average distribution information of the second aquatic organism in the second region, kmn is the average distribution information of the nth aquatic organism in the mth region, and t is the time it takes for the water level to drop and cause flooding. In this example, by using integration, the final curves can be guaranteed to be continuous curves. Therefore, by converting discrete nodes into continuous nodes, the final representation efficiency can be improved. The average distribution information can be understood as treating the aquatic organisms analogously and distributing them evenly across each region, thus enabling fast processing. The carbon emissions from aquatic organisms can be obtained through conventional statistical data, thus avoiding the impact of varying carbon emissions due to differences in water quality.

[0119] In this example, the distribution information of aquatic organisms is determined by environmental information, and the distribution information of carbon emissions from aquatic organisms is determined based on the distribution information of aquatic organisms. The carbon emission distribution information of aquatic organisms is combined with the water level drop curve to finally construct the carbon emission curve, which improves the accuracy of carbon emission curve construction.

[0120] In one possible implementation, after determining the carbon reduction of the target pumped-storage power station relative to the reference thermal power station based on the first carbon emission amount and the second carbon emission amount, the method further includes:

[0121] D1. Obtain information on the carbon emission requirements when the target pumped storage power station generates the target amount of electricity.

[0122] D2. If the carbon emission demand information is lower than the first carbon emission amount, then determine the carbon emission difference based on the fact that the carbon emission demand information is lower than the first carbon emission amount.

[0123] D3. Determine the actual operation information and actual energy consumption information of the target pumped storage power station based on the carbon emission difference.

[0124] The carbon emission requirement information can be obtained through user input. If the carbon emission requirement is lower than the first carbon emission requirement, dynamic fine-tuning is required to ensure that the target pumped storage power station can meet the carbon emission requirement.

[0125] The adjustable operational information of the target pumped storage power station during operation is obtained. This adjustable operational information can include time periods with electricity consumption and power supply source information within each time period. Based on the carbon emission difference, the optimal solution for the time period and power supply source information can be calculated, resulting in the optimal operating time period and optimal power supply source information. This optimal operating time period and optimal power supply source information are then determined as the actual operating information, and the corresponding energy consumption is determined as the actual energy consumption information. Specifically, the optimal solution for the time period and power supply source information can be calculated based on the carbon emission difference using the formula shown below:

[0126]

[0127] In the formula, Z represents the time period corresponding to the minimum value, and the power supply source information is the optimal solution; n represents the number of time periods; i represents the i-th time period among n time periods; m represents the number of power supply source information; j represents the j-th power supply source information among m power supply source information; c ij The carbon emission difference matrix represents the carbon emission difference in the i-th row and j-th column. This carbon emission difference matrix can be constructed based on the first carbon emission value for each time period. ij This represents the power supply source information for the time period in the i-th row and j-th column of the time period power supply source information matrix. The time period power supply source information matrix can be constructed based on the time periods with power consumption and the power supply source information within each time period.

[0128] In this example, the optimal solution for the time period and power supply source information is calculated by using the carbon emission difference, thereby obtaining the optimal operating time period and optimal power supply source information, and finally obtaining the actual operating information and actual energy consumption information, thus improving the accuracy of determining the actual operating information and actual energy consumption information.
