Description

Technical Field

[0001] This invention relates to the field of computer data processing, and more specifically to a method and apparatus for calibrating the total energy consumption of any industrial sector using electricity. Background Technology

[0002] With stricter energy consumption regulations, there is a need to obtain real-time dynamic total energy consumption data for various industries. An industry typically comprises numerous enterprises, each using various energy sources such as electricity, natural gas, oil, and coal. To statistically analyze an industry's energy consumption, each enterprise within that industry must report its individual energy consumption. However, while real-time dynamic data collection for electricity is established—for example, daily electricity consumption data and the current year's total energy consumption can be obtained dynamically—real-time usage or reserves for natural gas, oil, and coal are pre-stored energy sources. Therefore, it's difficult to dynamically obtain a company's total energy consumption, and consequently, the total energy consumption of an entire industry. A more traditional approach involves each industry obtaining energy consumption data reported by its enterprises from a statistical system. However, for enterprises, accurately calculating their own real-time energy consumption leads to inaccurate reported data, hindering a real-time and dynamic understanding of the industry's total energy consumption. Summary of the Invention

[0003] The purpose of this invention is to provide a method and apparatus for calibrating the total energy consumption of any industrial sector using electricity. By utilizing the characteristic that each industrial enterprise with a fixed production line in each sub-sector has a fixed energy consumption ratio, real-time dynamic and accurate electricity consumption data is introduced to calculate the real-time dynamic and accurate total energy consumption of each enterprise in the industry, thereby obtaining the total energy consumption of the industry in real-time dynamic.

[0004] On the one hand, this application provides a method for calibrating the total energy consumption of any industrial sector using electricity consumption, specifically including the following steps:

[0005] S1. Obtain the annual consumption of various energy sources for the fixed production line industry to be calibrated; denoted as E. t (a t b t c t , ..., d t The consumption of each type of energy source is then converted into the corresponding standard coal consumption, denoted as E. ct (a ct b ct c ct , ..., d ct );

[0006] S2, from E ctThe standard coal consumption a corresponding to obtaining electricity in China ct According to a ct and E ct (a ct b ct c ct , ..., d ct Calculate a ct In E ct The proportion of the steady state in the energy is denoted as the electrical energy proportion p;

[0007] S3. Obtain the current real-time total electricity consumption of all enterprises within the industry to be calibrated (specifically, E). a (Aa 当前 Ba 当前 Ca 当前 , ..., Da 当前 ), E a The equivalent of standard coal consumption when converted into electrical energy;

[0008] S4. Based on p and E a The standard coal consumption corresponding to the converted electrical energy is used to calculate the current real-time total energy consumption Q of the fixed production line industry to be calibrated.

[0009] For any industry, especially its sub-sectors (e.g., the food industry includes dairy production and snack processing; this application's focus on fixed-production-line industries refers to sub-sectors like dairy production or snack processing), while the annual energy consumption of each company within that industry is known, thus revealing the industry's total annual energy consumption, for energy sources like oil and coal, which are consumed in bulk, companies cannot obtain real-time consumption figures, making it impossible to determine the industry's real-time total energy consumption. Research has found that industrial production lines within an industry share similarities, featuring fixed production lines and similar production processes. Therefore, their energy consumption structures are roughly the same, and the energy consumption ratios between different pieces of equipment on a company's fixed production line are constant. Industrial companies with fixed production lines exhibit a fixed energy consumption ratio characteristic. Therefore, real-time estimation and statistics can be performed on industrial companies with fixed production lines to extrapolate their real-time total energy consumption, thereby obtaining the industry's real-time total energy consumption. This application uses electricity consumption to calibrate a company's real-time energy consumption. Since electricity is recorded by meters every day and every hour and is readily available in the power grid, the ratio of converted electricity to total energy consumption—the electricity percentage—can be used as an energy consumption ratio characteristic to estimate the industry's real-time total energy consumption. Industrial companies with fixed production lines have fixed energy consumption ratio characteristics. This energy consumption ratio characteristic (electricity percentage) objectively exists and can be extrapolated from historical data. After estimating this energy consumption ratio characteristic, real-time electricity consumption can be collected from the meters, converted into the consumption of standard coal, and then the real-time total energy consumption of the company can be calculated using the energy consumption ratio characteristic, thus obtaining the real-time total energy consumption of the industry to which the company belongs.

[0010] Furthermore, the specific process for calculating the current real-time total energy consumption Q of the fixed production line industry to be calibrated in step S4 is as follows:

[0011] Each enterprise's current real-time total electricity consumption is converted into the corresponding standard coal consumption E. ac (Aa c当前 Ba c当前 Ca c当前 , ..., Da c当前 );

[0012] Calculate the current real-time total energy consumption of each enterprise using the electricity consumption ratio; denoted as Q. 企 (Q A Q B Q C Q D ),

[0013] Q 企 Summing these values, we obtain the current total energy consumption Q of the fixed production line industry under test, Q = Q0 A +Q B +Q C +…+Q D .

[0014] The specific process of calculating the current real-time total energy consumption Q of the fixed production line industry to be calibrated in step S4 can also be as follows:

[0015] For E a Summing is performed to aggregate the current real-time total electricity consumption of each enterprise, resulting in the current real-time total electricity consumption E of the fixed production line industry to be calibrated. a当前 E a当前 =Aa 当前 +Ba 当前 +Ca 当前 +……+Da 当前 ;

[0016] E a当前 The equivalent of standard coal consumption in electrical energy, denoted as E. ac当前 ;

[0017] Using the proportion of electricity p and E ac当前 Calculate the current total energy consumption Q of the fixed production line industry to be calibrated.

[0018] Furthermore, the specific process for calculating the electrical energy proportion p in step S2 is as follows:

[0019] S21. Convert the annual consumption of each type of energy into the corresponding standard coal equivalent (E). t Find the total annual standard coal consumption E.总t E 总t =a ct +b ct +c ct +…+d ct ;

[0020] S22. Obtain the standard coal consumption a corresponding to electricity consumption for each year. ct Calculate the electricity consumption ratio p for each year. t ,

[0021] S23. Obtain the electricity share of the current year and the adjacent year N. When t is N, the electricity share of the adjacent year N is denoted as p. N Starting from the adjacent year N, iterate through the preceding years, selecting the electricity consumption ratio and p of the preceding years. N A stable interval is defined as T consecutive years of similar duration. The average annual electricity consumption ratio within this stable interval is calculated and taken as the electricity consumption ratio p.

[0022] Furthermore, the stability interval is determined as follows:

[0023] S231. Obtain the electricity consumption ratio for each year. Starting from the adjacent year N, iterate through the preceding years, calculating the electricity consumption ratio and p for years N-1, N-2...NT in sequence. N Is the difference between them less than 5%?

[0024] S232. If the electricity consumption percentage p for year NT is included in the calculation process. N-T With p N If the difference between them is not less than 5%, then the calculation will not continue.

[0025] S233. Take the T consecutive years between year N-T+1 and the adjacent year N as the stable interval.

[0026] In addition, this application provides a device for calibrating the total energy consumption of any industrial sector using electricity, comprising:

[0027] One or more processors;

[0028] A storage unit is used to store one or more programs, which, when executed by one or more processors, enable the one or more processors to implement the above-described method for calibrating the total energy consumption of any industrial sector using power consumption.

[0029] The beneficial effects of this invention are as follows:

[0030] This application obtains the annual energy consumption data of various types of energy in industries with fixed production lines, converts all energy types into standard coal consumption, and calculates the proportion of electricity in the total energy consumption. This yields the energy consumption characteristic ratio of the fixed production line industry, i.e., the electricity proportion rate. Since the electricity proportion rate is constant over a certain period, the industry to be calibrated can estimate its total energy consumption at that time based on real-time electricity consumption data of each enterprise within that industry. This facilitates real-time monitoring of the total energy consumption of various industries. Attached Figure Description

[0039] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0040] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0041] Example 1

[0042] The specific principles of this application are as follows:

[0043] For an industry, especially its sub-sectors (e.g., the food industry includes dairy production, snack processing, and beverage production; this application's "fixed production line industry" refers to sub-sectors like dairy production or snack processing), companies within each sub-sector typically have similar production processes and fixed production lines. Having fixed production lines means that companies within this sub-sector generally operate using a standardized process, with the equipment involved in production usually being fixed. Therefore, industries with fixed production lines have a fixed energy consumption ratio. Although each piece of equipment in each company uses different types of energy and consumes different amounts of energy per unit time, after merging all the equipment on the production line, the energy consumption ratio of different types used by a single production line is fixed per unit time. Generally, for an industry, it typically requires a relatively long period, such as during industrial restructuring, before companies within that industry replace their equipment with new energy types. Furthermore, once a fixed production line is established, it is not easily changed, and even if it is changed, it is not possible to update all relevant companies in a short period. Therefore, the energy ratio of an industry often remains stable over a relatively long time period.

[0044] Specifically, in the dairy production industry, each dairy company has the following production lines, which are simplified as follows:

[0045] This includes pumps for transporting milk, and pasteurization equipment for storing and heating milk for pasteurization; among which,

[0046] Pumps used for transporting milk are typically set to consume 'a' units of electricity per ton, meaning that transporting 1 ton of milk requires 'a' units of electricity. Sterilization equipment is typically set to consume 'd' units of natural gas per ton, meaning that sterilizing 1 ton of milk requires 'd' units of natural gas. Therefore, the energy consumption ratio is: electricity:gas = a:d. The total energy consumption of all types of energy is generally determined based on the equipment's operating time or the output produced. For example, if the total daily output is set at 5 tons, then the electricity consumption is 5*a, and the gas consumption is 5*d. Further assuming 200 days of production per year, with 5 tons produced each day, then the annual electricity consumption is 1000*a, and the annual electricity consumption is 1000*d.

[0047] For statistical systems, they typically calculate the total annual energy consumption of a certain type of energy in an industry, for example:

[0048] Annually: The total electricity consumption of industry X is A1, and the natural gas consumption is D1. It has been verified that although the annual values ​​of A1 and D1 of the industry change, the ratio of the two is similar to the ratio of a:d, and there is no large fluctuation. After analyzing the reasons, it was found that since the equipment on the production lines of each enterprise in the industry is fixed, although the annual output is different, this output is determined by the unit output and the number of days, not by the equipment.

[0049] Therefore, this invention uses the energy consumption ratio of different energy sources as a benchmark; by utilizing dynamic, total electrical energy data, it can push out the total energy consumption of all types of energy. It can also statistically analyze the real-time dynamic energy consumption of specific sub-sectors.

[0050] For detailed calculations, please refer to [link / reference]. Figure 1 Specifically, it includes the following steps:

[0051] S1. Obtain the annual consumption of various energy sources for the fixed production line industry to be calibrated; denoted as E. t (a t b t c t , ..., d t Various energy sources include electricity, oil, coal, or natural gas, for example, a t This represents the amount of electrical energy consumed per unit time, and so on; the consumption of each type of energy source is then converted into the corresponding standard coal consumption, denoted as E. ct (a ct b ct c ct , ..., d ct For example, a ct This indicates the amount of standard coal consumed per unit time in the conversion of electrical energy.

[0052] S2, from E ct The standard coal consumption a corresponding to obtaining electricity in China ct According to act and E ct (a ct b ct c ct , ..., d ct Calculate a ct In E ct The proportion of the steady state in the energy is denoted as the electrical energy proportion p;

[0053] The specific process for calculating the proportion of electricity (p) is as follows:

[0054] S21. Convert the annual consumption of each type of energy into the corresponding standard coal equivalent (E). t Find the total annual standard coal consumption E. 总t E 总t =a ct +b ct +c ct +…+d ct ;

[0055] S22. Obtain the standard coal consumption a corresponding to electricity consumption for each year. ct Calculate the electricity consumption ratio p for each year. t ,

[0056] S23. Obtain the electricity share of the current year and the adjacent year N. When t is N, the electricity share of the adjacent year N is denoted as p. N Starting from the adjacent year N, iterate through the preceding years, selecting the electricity consumption ratio and p of the preceding years. N A stable interval is defined as T consecutive years of similar duration. The average annual electricity consumption ratio within this stable interval is calculated and taken as the electricity consumption ratio p.

[0057] S3. Obtain the current real-time total electricity consumption of all enterprises within the industry to be calibrated, denoted as [missing information].

[0058] E a (Aa 当前 Ba 当前 Ca 当前 , ..., Da 当前 ), E a The equivalent of standard coal consumption when converted to electrical energy; Aa 当前 This indicates the current real-time total electricity consumption of Company A;

[0059] If the power system includes the power grid system or a company-built power consumption monitoring system, then the current real-time total power consumption 'a' is obtained. 当前The current real-time total electricity consumption of the industrial enterprise with the fixed production line to be calibrated can be obtained from the power grid system or from the power acquisition equipment built into the industrial enterprise with the fixed production line to be calibrated.

[0060] S4. Based on p and E a The standard coal consumption corresponding to the converted electrical energy is used to calculate the current real-time total energy consumption Q of the fixed production line industry to be calibrated.

[0061] Specifically, the methods for calculating the current real-time total energy consumption Q of the fixed production line industry to be calibrated in step S4 include the following two methods:

[0062] Method 1:

[0063] Each enterprise's current real-time total electricity consumption is converted into the corresponding standard coal consumption E. ac (Aa c当前 Ba c当前 Ca c当前 , ..., Da c当前 );

[0064] Calculate the current real-time total energy consumption of each enterprise using the electricity consumption ratio; denoted as Q. 企 (Q A Q B Q C Q D ), For example,

[0065] Q 企 Summing these values, we obtain the current total energy consumption Q of the fixed production line industry under test, Q = Q0 A +Q B +Q C +…+Q D .

[0066] Method 2:

[0067] For E a Summing is performed to aggregate the current real-time total electricity consumption of each enterprise, resulting in the current real-time total electricity consumption E of the fixed production line industry to be calibrated. a当前 E a当前 =Aa 当前 +Ba 当前 +Ca 当前 +……+Da 当前 ;

[0068] E a当前 The equivalent of standard coal consumption in electrical energy, denoted as E. ac当前 ;

[0069] Using the proportion of electricity p and E ac当前Calculate the current total energy consumption Q of the fixed production line industry to be calibrated.

[0070]

[0071] In analyzing the electricity share trends across various industries, the applicant discovered the following characteristics: If the electricity share in the most recent year exceeds 98% and generally does not fluctuate significantly, it indicates that companies in that industry have completed industrial upgrading and largely transitioned to clean energy, such as furniture manufacturing and instrument manufacturing. If the electricity share suddenly increases or decreases significantly, it indicates that the company is undergoing industrial restructuring, and the share in the following year generally will not decrease or increase significantly, remaining stable for a certain period. If the electricity share has been steadily and slowly increasing or decreasing for two consecutive years, the share in the following year will generally remain flat or continue to increase or decrease. If the electricity share has stabilized around a certain value since a certain year, the share in the following year will not change significantly relative to the share after that year. All of these electricity share trends share a common characteristic: within a continuous period adjacent to the current year, there exists a relatively stable range of electricity share.

[0072] Based on this characteristic, such as Figure 2 As shown, for the agricultural and sideline food processing industry, its energy consumption ratio has not changed much over the past ten years, indicating that its energy structure is relatively stable. Therefore, the proportion of electricity in this industry is within a stable range. The process of determining this stable range can be as follows:

[0073] S231. Obtain the electricity consumption ratio for each year. Starting from the adjacent year N, iterate through the preceding years, calculating the electricity consumption ratio and p for years N-1, N-2...NT in sequence. N Is the difference between them less than 5%?

[0074] S232. If the electricity consumption percentage p for year NT is included in the calculation process. N-T With p N If the difference between them is not less than 5%, then the calculation will not continue.

[0075] S233. Take the T consecutive years between year N-T+1 and the adjacent year N as the stable interval.

[0076] For example, if the current year is 2021, when calculating the electricity share of the current year, it is found that the electricity share of the current year was less than 5% for ten consecutive years from 2011 to 2020, and greater than 5% in 2010. Therefore, the year after 2010, that is, 2011-2020, is taken as the stable period.

[0077] In another implementation, the determination of the electricity proportion can also be:

[0078] Compare the current year's electricity share with the most recent year (i.e., the adjacent year) to see if there is a significant increase / decrease (more than 5%), or if the most recent year's share is not less than 0.98.

[0079] If so, the electricity share of the most recent year will be used as the electricity share of the current year.

[0080] Otherwise, compare the current year's electricity share with the previous two years to see if it has been steadily increasing / decreasing (the electricity share of the previous year did not exceed 5%). If so, the electricity share of the most recent year is used as the electricity share of the current year. Otherwise, iterate from the most recent year to the previous year until the difference between the electricity share of a certain year and the electricity share of the most recent year (adjacent year) exceeds 3%. Then, take the average of the electricity share of all years after the year that exceeds 3% as the electricity share of the current year.

[0081] In a specific use case, such as Figure 3 , Figure 4 As shown, for example, for each sub-sector, each sector has several enterprises with fixed production lines. The calibration system obtains the annual energy consumption data of each sector from the statistical system and calculates the annual electricity consumption ratio of each sector. If the annual electricity consumption of a sector is 'a', oil consumption is 'b', coal consumption is 'c', and natural gas consumption is 'd', then for each sector in each year, the standard coal consumption is converted according to the standard coal coefficient of each energy source. Assuming the standard coal coefficient of electricity is X1, the standard coal coefficient of oil is X2, the standard coal coefficient of coal is X3, the standard coal coefficient of natural gas is X4, and so on, then the converted total standard coal consumption = X1*a + X2*b + X3*c + X4*d... = a c +b c +c c +d c …The ratio of electricity consumption (converted to standard coal equivalent) to total standard coal consumption is calculated as X1*a: Total Consumption. From the industry's historical electricity consumption ratios, a stable interval is selected, with several consecutive years having similar ratios to the current year. The average annual electricity consumption ratio within this stable interval is then calculated and used as the electricity consumption ratio. To obtain the industry's current total energy consumption, the calibration system can obtain the current total electricity consumption of each enterprise within the industry. For example, obtaining the current total electricity consumption of enterprise A for the current year, converting the current total electricity consumption to standard coal consumption, denoted as X1*Aa. 当前 Using X1*Aa 当前 Company A's current total consumption = electricity consumption percentage, which gives us Company A's current total consumption Q.A When the current total electricity consumption of Company B for the current year is obtained, the current total electricity consumption is converted into standard coal consumption, denoted as X1*Ba. c当前 , using X1*Ba c当前 Company B's current total consumption = electricity percentage, which gives us Company B's current total consumption Q. B ...The current total energy consumption of all enterprises in the industry is aggregated and clustered to obtain cluster sets for different industries. The sum of these cluster sets yields the current total energy consumption for each industry in the current year. Alternatively, the current total electricity consumption of all enterprises in the current industry in the current year is obtained and summed to obtain the current total electricity consumption for the current year of the industry. This current total electricity consumption is then converted into standard coal consumption, and the current total electricity consumption for the current year of the industry is calculated based on the electricity consumption ratio.

[0082] Example 2: A computer-readable storage medium storing a computer program thereon, which, when executed by a processor, can implement the method for calibrating the total energy consumption of any industrial sector using electricity.

Based on the technical essence of the present invention, any simple modifications, equivalent substitutions, and improvements made to the above embodiments within the spirit and principles of the present invention shall still fall within the protection scope of the present invention.
