[0002] Natural gas, as an important green, environmentally friendly, safe and reliable energy source, has been widely used as city gas and industrial fuel.

[0003] Currently, my country's natural gas pipeline transportation prices are set according to the principle of "permitted cost plus reasonable profit," which means that the permitted cost of pipeline transportation companies is determined, the permitted profit is monitored, and factors such as taxes are considered to determine the total permitted revenue resources for the year, and pipeline transportation resources are determined accordingly.

[0004] However, for long-distance gas pipelines, resource-influencing factors such as transmission costs, management costs, and demand vary across different regions. Using a uniform standard to determine resources could lead to unreasonable pipeline resource allocation in some areas.

[0060] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0061] It should be understood that "several" in this article refers to one or more, and "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0062] The natural gas pipeline resource determination method provided in this application can be applied to computer equipment with data processing capabilities. The computer equipment can be a personal computer, portable computer, workstation, or server, or other equipment with strong data processing capabilities. This application does not limit the specific equipment type. For ease of description, the following embodiments use the application of the natural gas pipeline resource determination method to a computer equipment as an example.

[0063] Figure 1 This is a flowchart illustrating a method for determining natural gas pipeline resources according to an exemplary embodiment. This method can be applied to a system including computer equipment. The computer equipment calculates target values ​​for pipeline resources corresponding to each target pricing region by acquiring optimized natural gas flow relationships, thereby improving the rationality of pipeline resource determination. Figure 1 As shown, the method for determining natural gas pipeline resources may include the following steps:

[0064] Step 101: Use the production, transportation, storage and sales optimization model to obtain natural gas transportation information in the target area; the natural gas transportation information is used to indicate the natural gas transportation flow relationship in the target area; the target area includes at least one target transportation region.

[0065] Currently, domestic natural gas transportation prices are set according to the principle of "permitted costs plus reasonable profits." This means that the annual permitted total revenue is determined by verifying the permitted costs of pipeline transportation companies, monitoring permitted profits, and considering factors such as taxes, and then the pipeline transportation price is determined accordingly. In short-distance pipeline transportation, the pipeline construction entities are relatively homogeneous, and the differences in price-influencing factors such as natural gas supply, sales volume, and transportation costs between different regions are small, making a unified pricing mechanism feasible. However, in long-distance pipeline transportation, the pipeline length, natural gas demand, and transmission costs vary significantly across regions. If a unified pricing mechanism is still adopted, natural gas charges would lack rationality and would be detrimental to the development of local natural gas markets and local economies.

[0066] In this embodiment of the application, the computer device constructs a natural gas production, transportation, storage and sales optimization model, which uses the actual natural gas supply and demand in the target area and the natural gas transportation information in the target area to indicate the natural gas transportation flow relationship in the target area.

[0067] Among them, the production, transportation, storage and sales optimization model is used to generate optimization parameters in the natural gas production, transportation, storage and sales structure with the goal of maximizing supply chain profits.

[0068] In one possible implementation, the pipeline network in the target area is either a natural gas ring network or a non-ring network.

[0069] Since there are multiple natural gas sources and several demand points in the target area, the natural gas transportation flow can be optimized and adjusted. The adjustments can include adjusting the natural gas sources supplying each demand point, adjusting the amount of natural gas transported from each source to the demand point, and adjusting the natural gas transportation distance from each source to each demand point, i.e., pipeline length.

[0070] In one possible implementation, the computer equipment utilizes a natural gas production, transportation, storage, and sales optimization model and historical natural gas production, transportation, storage, and sales data to obtain natural gas transportation information. The production, transportation, storage, and sales optimization model is a mathematical model used to solve the optimization and allocation problem of a natural gas transportation system. Optionally, given the known natural gas production and sales structure, pipeline transportation network, and gas storage peak-shaving capacity, the production, transportation, storage, and sales optimization model can specify production and sales plans based on known conditions and optimize natural gas allocation paths, arranging production and supply with the goal of maximizing a weighted sum of profit and social welfare; or, given the known production and sales structure, it can plan medium- and long-term pipeline investment plans and determine an optimized pipeline transportation network to achieve a match between pipeline capacity and production and sales structure; or, under various external gas export structures, it can determine the optimal production and sales structure, pipeline investment plan, and natural gas allocation plan, etc., to maximize benefits under a comprehensive performance system. In this embodiment, the computer equipment uses the trained production, transportation, storage, and sales optimization model to obtain an optimized pipeline network for indicating natural gas flow relationships, enabling natural gas pipeline pricing to be customized based on the optimized production, transportation, storage, and sales structure, thereby increasing profits while maintaining reasonable pricing.

[0071] Step 102: Based on natural gas transportation information, obtain the target pipeline parameters for each target transportation pipeline used to transport natural gas to the target transportation area; the target pipeline parameters are used to indicate the natural gas transportation allocation.

[0072] In this embodiment of the application, based on the optimized natural gas transportation information output by the production, transportation, storage and sales optimization model, it is possible to determine each target transportation area in the target region, as well as the allocation of natural gas transportation to each target transportation area.

[0073] Step 103: Based on the target pipeline parameters and the average value of pipeline resources, obtain the target value of pipeline resources corresponding to the target transportation area; the average value of pipeline resources is obtained by averaging the base values ​​of each pipeline resource in the target area; pipeline resources are the resources required to transport a unit volume of natural gas.

[0074] In this embodiment of the application, the computer device calculates the target value of the pipeline resources corresponding to each target transportation area based on the obtained natural gas allocation information corresponding to each target transportation area and the average value of each pipeline resource in the target area.

[0075] For example, Figure 2 This is a schematic diagram illustrating the natural gas flow relationship in a target area, as described in an embodiment of this application. Figure 2As shown, natural gas is supplied from gas sources 1, 2, and 3 in the target area. Gas source 1 transports natural gas to various demand points in price zone 1 via pipeline 1, and gas source 2 transports natural gas to various demand points in price zone 2 via pipeline 4, and gas source 3 transports natural gas to various demand points in price zone 2 via pipeline 3. Natural gas demand points transported via the same gas source and pipeline belong to the same price zone, i.e., the same target transportation area.

[0076] In summary, the solution presented in this application obtains natural gas transportation information for a target region through a natural gas production, transportation, storage, and sales optimization model. Based on the natural gas flow direction relationships within this transportation information, the path method is used to calculate parameters for each target transportation area within the target region according to the allocation of natural gas during transportation. This allows for the calculation of the target value of pipeline resources for each target transportation area based on the parameters corresponding to that area. This solution enables the acquisition of optimized natural gas flow direction relationships using a production, transportation, storage, and sales optimization model. The optimized flow direction relationships improve the accuracy of determining the target value of natural gas pipeline resources, thereby reasonably determining the target value of natural gas pipeline resources for each area within the target region.

[0077] The embodiments shown in this application can be applied to scenarios where regional pricing is implemented using a natural gas ring pipeline network. This allows for the reasonable determination of regional pricing based on pipeline routes, thereby improving the fairness of regional pricing. In this application scenario, pipeline resources can be resources such as points or currency. Figure 3 This is a flowchart illustrating a method for determining natural gas pipeline transportation resources according to an exemplary embodiment. This method can be applied to a system including computer equipment. The computer equipment calculates target values ​​for pipeline resources corresponding to each target transportation area by acquiring optimized natural gas flow direction relationships, thereby improving the rationality of pipeline resource determination. Figure 3 As shown, the method for determining natural gas pipeline resources may include the following steps:

[0078] Step 301: Use the production, transportation, storage and sales optimization model to obtain natural gas transportation information in the target area.

[0079] In one possible implementation, the production, transportation, storage, and sales optimization model is a mixed-integer linear programming model designed to satisfy constraints on natural gas supply and demand conservation, natural gas flow conservation, natural gas transmission and distribution capacity limitations, and natural gas storage capacity limitations. This model generates optimal parameters for the natural gas production, transportation, storage, and sales structure with the objective of maximizing supply chain profits.

[0080] For example, given the known production and sales structure, pipeline network, and gas storage peak-shaving capacity, a production and sales plan is formulated and the allocation path is optimized. The first-level optimization objective is to maximize the weighted sum of corporate profit and social welfare, arranging production and supply. Under dynamically changing production and sales structures, a medium- to long-term pipeline investment plan is planned to achieve a match between pipeline capacity and the production and sales structure and quantity, serving as the second-level optimization objective. Under various external gas export structures, the optimal production and sales layout, pipeline investment, and natural gas allocation are sought to maximize benefits under a comprehensive performance system, serving as the third-level optimization objective. Furthermore, the computer equipment incorporates constraints such as the conservation relationship between gas storage volume and pipeline flow rate, the gas supply being less than the gas source capacity, the conservation of natural gas volume obtained by each demand node and pipeline flow rate, and the conservation of natural gas inflow and outflow at nodes in each pipeline transportation network. Penalty terms are also added to construct a complete production, transportation, storage, and sales optimization model.

[0081] For example, the formula corresponding to the production, transportation, storage and sales optimization model is shown below.

[0082]

[0083] Where maxz represents maximizing the overall profit of the supply chain, the first polynomial of the above formula is as follows:

[0084]

[0085] The first polynomial indicates downstream sales revenue, t indicates time, T indicates the set of time periods for the entire plan, j indicates pipeline connections or intersections, D indicates the set of demand points, and α... jt Used to indicate the proportion of gas supplied at demand point j to its current demand t, d jt Used to indicate the demand quantity at demand point j, p jt Used to indicate the price of natural gas at demand point j in period t.

[0086] The second polynomial is as follows:

[0087]

[0088] The second polynomial indicates the cost of natural gas production, where i indicates the gas source and S indicates the set of supply points, including natural gas producing fields and external gas supply nodes. Used to indicate the unit cost of natural gas from gas source i in period t; J is used to indicate a set of pipeline connections or intersections; q ijt Used to indicate the amount of transported between each pipe segment (i,j) at time t.

[0089] The third polynomial is as follows:

[0090]

[0091] The third polynomial indicates the transportation cost of natural gas, where C indicates the set of gas storage facilities. ij Used to indicate the pipeline transportation cost per unit gas volume for pipeline segment (i,j).

[0092] The fourth polynomial is as follows:

[0093]

[0094] The fourth polynomial is used to indicate the cost of gas injection and extraction in a gas storage facility, where M indicates the upper limit of the gas injection capacity of the storage facility. m is used to indicate the unit gas injection cost of gas storage i. it Used to indicate the amount of gas injected into peak-shaving gas storage unit i during period t.

[0095] The fifth polynomial is as follows:

[0096]

[0097] The fifth polynomial indicates the fixed investment cost, Φ indicates the set of investment pipeline types, and Y indicates the set of annual planning periods, such as quarters or months. Used to indicate the construction between pipe segments (i,j) Total depreciation expense of fixed costs for this type of pipeline. Used to indicate the status of pipeline investment, when at the beginning of period t, there are already invested pipeline segments (i,j). Pipes otherwise

[0098] The sixth polynomial is as follows:

[0099]

[0100] The sixth polynomial is a penalty term added to the model, where e i This is used to indicate the penalty coefficient for a unit of gas shortage when the minimum supply requirement at demand point i is not met.

[0101] Among them, the production, transportation, storage and sales optimization model can be solved by using the Benders decomposition algorithm.

[0102] For example, the computer device can use the Benders decomposition algorithm as the model solving algorithm to decompose the optimization problem of natural gas production, transportation, storage, and sales into one main problem and one sub-problem. Through iterative solving between the main problem and the sub-problem, the optimal solution is finally obtained. Optionally, in this embodiment, the main problem is the investment decision of gas transportation pipelines, and the sub-problem is the decision of natural gas production, transportation, peak shaving, and sales under the pipeline investment scheme fed back by the main problem.

[0103] In one possible implementation, natural gas transportation information is used to indicate the flow of natural gas transportation within a target area.

[0104] The target region may include at least one target transportation area. In scenarios where pipeline transportation prices are determined for a target transportation area, the target transportation area may also be a target pricing area.

[0105] In one possible implementation, computer equipment acquires the location information of each natural gas supply point and the corresponding natural gas supply volume for each supply point in the target area, as well as the location information of each natural gas demand point and the corresponding natural gas demand volume. Then, the location information of each natural gas supply point, the corresponding natural gas supply volume, the location information of each natural gas demand point, and the corresponding natural gas demand volume are input into a production, transportation, storage, and sales optimization model to obtain natural gas transportation information in the target area. Based on the natural gas transportation information in the target area, pipeline network structure information is obtained.

[0106] The production, transportation, storage, and sales optimization model can optimize the natural gas production, transportation, storage, and sales structure based on input quantities to obtain optimized output quantities. Pipeline network information is used to indicate the direction of natural gas transportation in the target area to the corresponding pipeline structure.

[0107] Step 302: Based on the pipeline network structure information of the target area, determine the target transportation pipelines and target pipeline parameters of each target transportation area.

[0108] In this embodiment, the computer device, by acquiring optimized pipeline network structure information of the target area, can determine each target transportation area within the target area and obtain the target transportation pipelines and their parameters for each target transportation area. Natural gas is transported to demand points within the same target transportation area via the same target transportation pipeline.

[0109] The target pipeline parameters include the pipeline path and the pipeline volume corresponding to the target transport pipeline; the pipeline path includes the pipeline length and pipeline direction.

[0110] For example, such as Figure 2As shown, by obtaining the optimized pipeline network structure information in the target area, the computer device can determine that the target area contains price zone (target pricing area) 1 and price zone 2, and can obtain that the target transportation pipelines corresponding to price zone 1 are pipeline 1 and pipeline 2, and obtain the pipeline length and pipeline direction of pipeline 1 and pipeline 2 respectively.

[0111] Step 303: Obtain the pipeline length and pipeline capacity of each target transportation pipeline that transports natural gas to the target transportation area.

[0112] In one possible implementation, the computer device obtains the pipeline length corresponding to the target transport pipeline to the target delivery area and the natural gas transport volume corresponding to the target transport pipeline.

[0113] The sum of the pipeline transport volumes corresponding to each target transport pipeline is the total supply volume of the target transport area.

[0114] For example, such as Figure 2 As shown, the target transportation pipelines corresponding to price zone 1 are pipeline 1 and pipeline 2. The pipeline transportation volume corresponding to pipeline 1 is x, the pipeline transportation volume corresponding to pipeline 2 is y, and the total natural gas supply corresponding to price zone 1 is x+y.

[0115] Step 304: Determine the ratio of the pipeline transport volume corresponding to each target transport pipeline to the total supply volume as the pipeline supply ratio corresponding to the target transport pipeline.

[0116] In the scenario where the pipeline transportation price for the target transportation area is determined, the formula for the pipeline supply ratio can be as follows.

[0117]

[0118] For example, if the pipeline transport volume corresponding to pipeline 1 is x, and the pipeline transport volume corresponding to pipeline 2 is y, then the pipeline supply ratio corresponding to pipeline 1 is... Pipeline 2 corresponds to the pipeline supply ratio of

[0119] Step 305: The average transportation mileage corresponding to the target transportation area is obtained by adding the product of the pipeline length of each target transportation pipeline and the pipeline supply ratio corresponding to the target transportation pipeline.

[0120] For example, such as Figure 2 As shown, if the distance for transporting natural gas via pipeline 1 is b kilometers, and the distance for transporting natural gas via pipeline 2 is c kilometers, and the pipeline supply share corresponding to pipeline 1 is... Pipeline 2 corresponds to the pipeline supply ratio of The formula for calculating the average transportation mileage corresponding to target pricing zone 1 can be shown below.

[0121]

[0122] Step 306: Based on the average transportation mileage and the average value of pipeline resources, determine the target value of pipeline resources corresponding to the target transportation pipeline.

[0123] In the scenario where the pipeline transportation price for the target transportation area is determined, the average value of the pipeline transportation resources can be the average pipeline transportation price, and the target value of the pipeline transportation resources can be the target pipeline transportation resources.

[0124] In this embodiment of the application, the computer device can obtain the target pricing coefficient corresponding to the target pricing area based on the average transportation mileage, and calculate the target pipeline pricing corresponding to the target pricing area based on the target pricing coefficient and the average transportation mileage.

[0125] In one possible implementation, the computer device adds up the average transport mileages of each target area to obtain the total transport mileage corresponding to the target area. Then, by dividing the total transport mileage by the number of target transport areas in the target area, the average overall transport mileage corresponding to the target area is obtained. Based on the average transport mileage corresponding to the target transport area and the average overall transport mileage, the target pipeline resource coefficient corresponding to each target transport area is determined. Based on the target pipeline resource coefficient and the average value of the pipeline resources, the target value of the pipeline resources corresponding to the target transport area is obtained.

[0126] Among them, the target pipeline resource coefficient can be the target pricing coefficient, which is used to determine the target pipeline pricing for the target pricing area.

[0127] Specifically, the target pricing coefficient is determined by calculating the ratio between the average transport mileage corresponding to the target pricing area and the overall average transport mileage. Furthermore, the target pipeline pricing for the target pricing area is calculated by multiplying the target pricing coefficient by the average pipeline transportation price.

[0128] For example, such as Figure 2 As shown, the average transportation mileage corresponding to price zone 1 is m, and the average transportation mileage corresponding to price zone 2 is n. If the target area only includes price zone 1 and price zone 2, the average overall transportation mileage of the target area can be calculated using the following formula.

[0129]

[0130] The target pricing coefficient K1 corresponding to price zone 1 can be calculated using the following formula.
