[0041] In order to make the purpose, technical scheme and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.
[0042] In this document, "multiple" refers to two or more. The association relationship of "and / or" describing the associated objects means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. The character " / " generally represents an "or" relationship between the front and rear associated objects.
[0043] The natural gas pipeline transportation resource determination method provided by the embodiments of the present application can be applied to a computer device with a data processing function, which can be a personal computer, a portable computer, a workstation, a server or other devices with strong data processing capability. The embodiments of the present application do not limit the specific device type, and for the convenience of description, the following embodiments are described by taking the application of the natural gas pipeline transportation resource determination method to a computer device as an example.
[0044] Please refer to Figure 1 which shows a flowchart of the natural gas pipeline transportation resource determination method provided by an example embodiment of the present application. The method can include the following steps:
[0045] In step 101, a target resource determination parameter is obtained by using a production, transportation, storage and sales optimization model, wherein the resource determination parameter is used to indicate the influencing factors of the natural gas pipeline transportation resource.
[0046] In the embodiments of the present application, the resource can be points, prices, etc. The following embodiments are illustratively described by taking the natural gas pipeline transportation price as the natural gas pipeline transportation resource.
[0047] At present, in the transportation process of natural gas in a short distance pipeline, the pipeline construction subject is relatively single, and the differences between the influencing factors such as the natural gas supply amount, the sales amount (demand amount), the transportation cost, etc. in the passing areas are small, which has the conditions for unified pricing. In the transportation process of natural gas in a long distance pipeline, especially in cross-province transportation, the differences between the transportation pipeline lengths, the demand amounts of natural gas and the transportation costs, etc. in the passing areas are large. If the unified pricing is still adopted, the natural gas charging lacks rationality, which is not conducive to the development of the natural gas market and the local economy in each area.
[0048] The embodiments of the present application determine the resource determination parameter based on the influencing factors of the natural gas pipeline transportation resource, determine the target natural gas pipeline transportation resource of the target transportation area by using the specific target resource determination parameter of the target transportation area in the natural gas transportation process and the influence direction of various parameters on the natural gas pipeline transportation resource (for example, the natural gas pipeline transportation price).
[0049] In a possible implementation, the computer device obtains the target resource determination parameter by using a natural gas production, transportation, storage and sales optimization model and historical natural gas production, transportation, storage and sales data. The natural gas production, transportation, storage and sales optimization model is a mathematical model for solving the optimization deployment problem of a natural gas transportation system. Optionally, under the conditions of known natural gas production and sales structure, pipeline transportation network and gas storage peak shaving capability, the natural gas production, transportation, storage and sales optimization model can specify a production and sales scheme based on the known conditions, and optimize the natural gas deployment path to arrange production and supply with the maximum profit and social welfare weighted sum as the target. Alternatively, under the condition of known production and sales structure, the natural gas production, transportation, storage and sales optimization model can plan a medium and long term pipeline investment scheme to determine an optimized pipeline transportation network to realize the matching of pipeline transportation capacity and production and sales structure. Alternatively, under various external gas structure conditions, the natural gas production, transportation, storage and sales optimization model can determine an optimized production and sales structure, pipeline investment scheme and natural gas deployment scheme to realize the maximum benefit under a comprehensive performance system. For example, the computer device obtains the parameter for determining the natural gas pipeline transportation price by using the trained natural gas production, transportation, storage and sales optimization model, so that the natural gas pipeline transportation price is customized based on the optimized production, transportation, storage and sales structure, thereby improving the profit on the basis of reasonable pricing.
[0050] In step 102, the target resource determination parameter is input into a resource prediction model to generate a target resource determination coefficient, which is used to indicate the relationship between the target transportation area and the natural gas pipeline transportation resource of the passing area of the natural gas pipeline.
[0051] The resource prediction model is a simple mathematical model for generating the resource determination coefficient based on the relationship between the resource determination parameter and the natural gas pipeline transportation resource, and is used to indicate the relationship between the target transportation area and the natural gas pipeline transportation resource of the passing area of the natural gas pipeline. If the target resource determination coefficient is greater than 1, it indicates that the target natural gas pipeline transportation resource of the target transportation area is greater than the average pipeline transportation resource of the natural gas transportation. If the target resource determination coefficient is less than 1, it indicates that the target natural gas pipeline transportation resource of the target transportation area is less than the average pipeline transportation resource of the natural gas transportation area as a whole. For example, the computer device inputs the target price determination parameter into the resource prediction model to generate the target price determination coefficient.
[0052] In step 103, the target natural gas pipeline transportation resource of the target transportation area is obtained based on the target resource determination coefficient and the average pipeline transportation resource. The average pipeline transportation resource is the average value of the basic pipeline transportation resources of the passing areas.
[0053] The average pipeline transportation resource is the standard resource of the total natural gas transportation area. The resource determination parameter is generated based on the influencing factors of the natural gas pipeline transportation resource in the target transportation area, and the average pipeline transportation resource is corrected to obtain the target natural gas pipeline transportation resource, which can fully consider the actual natural gas transportation situation of the target transportation area on the basis of conforming to the overall transportation production and sales structure.
[0054] In a possible implementation, the formula for calculating the target natural gas resource is target natural gas resource = target resource determination coefficient * average pipeline resource.
[0055] As shown in FIG. 1, there is a cross-regional natural gas transportation between region A and region B, and the average pipeline price of the two regions is 1.5 yuan / m3. The price coefficient generated by the computer device based on the pricing parameter of region A is 0.9, and thus the actual natural gas price of region A is 1.35 yuan / m3. The price coefficient generated by the computer device based on the pricing parameter of region B is 1.1, and thus the actual natural gas price of region B is 1.65 yuan / m3. Figure 2
[0056] In summary, in the embodiments of the present application, for the target delivery region in each region through which the natural gas pipeline passes, the target resource determination coefficient is determined by using the target resource determination parameter in the natural gas production, transportation, storage and sales structure, and the natural gas pipeline resource of the target delivery region is calculated by using the coefficient method. The parameter selection and resource calculation are relatively convenient, the natural gas pipeline resource can be regionally personalized for different regions through which the same pipeline passes, and reasonable natural gas pipeline resource can be obtained. In addition, the optimized target resource determination parameter is obtained by using the production, transportation, storage and sales optimization model, and the overall benefit of cross-regional natural gas transportation can be improved on the basis of determining the resource in different regions.
[0057] Please refer to FIG. 2, which shows a flowchart of a natural gas pipeline resource determination method provided by another exemplary embodiment of the present application. The method can include the following steps: Figure 3
[0058] Step 301, in the topological structure model, a target function is determined based on a natural gas transportation optimization target, at least one constraint condition and a penalty term are added, and a production, transportation, storage and sales optimization model is constructed.
[0059] Before the computer device calculates the target natural gas resource of the target delivery area, an optimization model of production, transportation, storage and sales needs to be constructed, so that an optimized resource determination parameter is obtained based on the optimization model of production, transportation, storage and sales, and the rationality of the natural gas delivery resource is ensured. In a possible implementation, the computer device constructs an optimization model of production, transportation, storage and sales of natural gas based on elements such as a natural gas production source, a pipeline transportation network node, a natural gas storage node, a natural gas demand node and a transportation pipeline, wherein the optimization model of production, transportation, storage and sales contains at least one optimization target. For example, under the condition of known production and sales structure, pipeline transportation network and storage peak regulation capacity, a production and sales scheme is formulated and an optimized allocation path is optimized, and enterprise profit and social welfare weighted sum maximization is taken as a first-layer optimization target to arrange production and supply; under the condition of dynamically changing production and sales structure, a medium and long-term pipeline investment scheme is planned to realize matching of pipeline transportation capacity and production and sales structure and quantity as a second-layer optimization target; under various external gas structure conditions, an optimal production and sales layout, pipeline network investment and natural gas allocation are found to realize benefit maximization under a comprehensive performance system as a third-layer optimization target. In addition, the computer device takes the conservation relationship between the gas production capacity of the storage and the pipeline flow rate, the gas source supply capacity less than the gas source production capacity, the conservation of the natural gas quantity obtained by each demand node and the pipeline flow rate, and the conservation of the natural gas inflow and outflow at each node in the pipeline transportation network as constraint conditions, and adds a penalty term to construct a complete optimization model of production, transportation, storage and sales.
[0060] In step 302, the Benders decomposition algorithm is used to solve the optimization model of production, transportation, storage and sales.
[0061] In a possible implementation, the computer device uses the Benders decomposition algorithm as a model solving algorithm, and decomposes the optimization problem of natural gas production, transportation, storage and sales into a main problem and a sub-problem, and finally obtains an optimal solution through iterative solving between the main problem and the sub-problem. Optionally, the main problem in the embodiment of the present application is the investment decision of the natural gas transportation pipeline, and the sub-problem is the natural gas production, transportation, peak regulation and sales decision under the pipeline investment scheme fed back by the main problem.
[0062] In step 303, the optimization model of production, transportation, storage and sales is used to obtain a target resource determination parameter, wherein the resource determination parameter is used to indicate an influencing factor of the natural gas pipeline transportation resource.
[0063] The influencing factors of the natural gas pipeline transportation resource considered in the natural gas pipeline transportation resource determination method in the embodiments of the present application include natural gas transportation pipeline length (i.e. pipeline transportation fixed assets), natural gas production, natural gas demand and natural gas production, transportation, storage and sales cost. In a possible implementation, the target pipeline parameters include target pipeline length and total pipeline length, the target demand parameters include target demand and total demand, the target supply parameters include target supply and total supply, and the target cost parameters include fixed cost parameters and variable cost parameters. The target pipeline length is the sum of the lengths of each natural gas transportation pipeline in the target transportation area, the total pipeline length is the sum of the lengths of the transportation pipelines in the areas through which the natural gas is transported, for example, the gas source in area B transports natural gas to area B and area A through pipeline 1 and pipeline 2, and when the target natural gas pipeline transportation resource of area A is calculated, the target pipeline length is the sum of the lengths of pipeline 1 and pipeline 2 in area A, and the total pipeline length is the sum of the lengths of complete pipeline 1 and pipeline 2. The target demand is the natural gas demand in the target transportation area, and the total demand is the sum of the demands of each area through which the natural gas is transported. The target supply is the natural gas supply in the target transportation area, and the total supply is the sum of the natural gas supplies of each area, for example, the gas source in area B transports natural gas to area B and area A, and when the target natural gas pipeline transportation resource of area A is calculated, the target demand is the natural gas demand of area A, the total demand is the sum of the natural gas demands of area A and area B, the target supply is the natural gas supply in area A, and the total supply is the sum of the natural gas supplies of area A and area B.
[0064] In a possible implementation, step 303 includes the following steps:
[0065] Step 303a: obtaining the target supply, total supply, total demand, target pipeline length and total pipeline length in the target time length through the network.
[0066] In a possible implementation, the computer device can automatically obtain the target supply, total supply, total demand, target pipeline length and total pipeline length of the natural gas transportation in the target time length from the authoritative website through a preset search program or a crawler program.
[0067] Illustratively, the computer device obtains the supply of area A in the past year, the pipeline length, and the sum of the supply, pipeline length and demand of other areas involved in the natural gas transportation pipeline network of area A in the past year.
[0068] Step 303b: inputting the target supply, total supply, total demand, target pipeline length and total pipeline length into the production, transportation, storage and sales optimization model to obtain the target demand.
[0069] Illustratively, the production-transportation-storage-sale optimization model is used to optimize the production-transportation-storage-sale of natural gas based on the input data to maximize the profit of the supply chain, and obtain the output data after optimization.
[0070] In another possible implementation, the computer device can determine the target resource determination parameter based on the total supply, the target demand, the total demand, the target pipeline length, and the total pipeline length to obtain the optimized target supply, and step 303 includes the following steps:
[0071] Step 303c: obtaining the total supply, the target demand, the total demand, the target pipeline length, and the total pipeline length within the target time period through the network.
[0072] Similarly, the computer device can automatically obtain the total supply, the target demand, the total demand, the target pipeline length, and the total pipeline length of natural gas transportation within the target time period from the authoritative website through the preset search program or the crawler program.
[0073] Step 303d: inputting the total supply, the target demand, the total demand, the target pipeline length, and the total pipeline length into the production-transportation-storage-sale optimization model to obtain the target supply.
[0074] Illustratively, the production-transportation-storage-sale optimization model is used to optimize the production-transportation-storage-sale structure of natural gas based on the input data to maximize the profit of the supply chain, and obtain the output data after optimization.
[0075] The above steps 303a to 303b, 303c, and 303d are in a parallel relationship, and the computer device determines the target resource determination parameter by using any of the above parameter acquisition methods, or in other possible implementations, the computer device can also use other parameter acquisition methods, which are not limited in the embodiments of the present application.
[0076] Step 304: inputting the target pipeline parameter, the target demand parameter, the target supply parameter, and the target cost parameter into the resource prediction model to generate the target resource determination coefficient.
[0077] The target pipeline parameter includes the target pipeline length and the total pipeline length, the target demand parameter includes the target demand and the total demand, the target supply parameter includes the target supply and the total supply, and the target cost parameter includes the fixed cost parameter and the variable cost parameter.
[0078] In a possible implementation, step 304 includes the following steps:
[0079] In step 304a, a first coefficient is determined based on the target pipeline length, the total pipeline length, the target demand, the total demand, and a fixed cost parameter, the first coefficient being used to indicate a ratio of the fixed cost of unit pipeline transportation in the target region to an average fixed cost, the target pipeline length, the total demand, and the fixed cost parameter being in a positive proportional relationship with the first coefficient, and the total pipeline length and the target demand being in an inverse proportional relationship with the first coefficient.
[0080] In one possible implementation, a principle for determining the natural gas pipeline transportation resource (e.g., the natural gas pipeline transportation price) is that the greater the pipeline fixed assets in the target transportation region (in the embodiment of the present application, the target pipeline length is used to represent the pipeline fixed assets in the target transportation region), the greater the corresponding target natural gas pipeline transportation resource, the greater the amount of natural gas entering the pipeline transportation network in the target transportation region (i.e., the actual transportation amount, in the embodiment of the present application, the target supply amount is used to represent the actual transportation amount in the target transportation region), the greater the corresponding target natural gas pipeline transportation resource, and the greater the demand for natural gas in the target transportation region, the smaller the corresponding target natural gas pipeline transportation resource. The computer device determines the first coefficient based on the corresponding relationship between each parameter and the target natural gas pipeline transportation resource.
[0081] Illustratively, the calculation formula of the first coefficient is as follows:
[0082]
[0083] In the formula, a is the fixed cost parameter.
[0084] In step 304b, a second coefficient is determined based on the target demand, the total sales amount, the target supply amount, the total supply amount, and a variable cost parameter, the second coefficient being used to indicate a ratio of the variable cost of unit pipeline transportation in the target region to an average variable cost, the target supply amount, the total demand, and the variable cost parameter being in a positive proportional relationship with the second coefficient, and the total supply amount and the target demand being in an inverse proportional relationship with the second coefficient.
[0085] The second coefficient is determined based on the principle for determining the natural gas pipeline transportation resource in step 304a. Illustratively, the calculation formula of the second coefficient is as follows:
[0086]
[0087] In step 304c, the sum of the first coefficient and the second coefficient is determined as a target resource determination coefficient.
[0088] In one possible implementation, the sum of the fixed cost parameter and the variable cost parameter is 1. Optionally, other types of cost parameters can also be included in the resource prediction model.
[0089] Illustratively, in the resource prediction model, the calculation formula of the target resource determination coefficient is as follows:
[0090]
[0091] Wherein, a is a fixed cost parameter, and 1-a is a variable cost parameter. The computer device performs operation on the obtained target resource determination parameter based on the above formula to obtain a target resource determination coefficient.
[0092] In step 305, a target natural gas pipeline transportation resource of the target transportation area is obtained based on the target resource determination coefficient and an average pipeline transportation resource. The average pipeline transportation resource is an average value of the basic pipeline transportation resources of each of the passage areas.
[0093] The specific implementation of step 305 can refer to the above step 103, and will not be described here in detail.
[0094] In the embodiment, the computer device can obtain the optimized target resource determination parameter through different ways by using the production-distribution-storage-sale optimization model, thereby improving the reliability of the target resource determination parameter. The influence of the pipeline length, the natural gas supply amount and the natural gas demand amount on the natural gas transportation resource can be fully considered, the selection of the parameter and the calculation of the resource are relatively simple, and the pipeline transportation resource determination efficiency is high.
