Problems solved by technology

However, due to the far distance between the place of production and the place of sale, the distribution of the market is relatively scattered, and the demand of users is volatile, so there is inhomogeneity in time and space. At the same time, the algorithm also has the problem of high computational cost.

Embodiment Construction

[0041] Below in conjunction with accompanying drawing and embodiment the present invention will be further described

[0042] Example. A gas pipeline network including two gas sources (A, B), two users (D, E), and natural gas company C (as attached image 3 shown).

[0043] The following formulates the optimal gas transmission and distribution scheme for the pipeline network with a planning period of one month

[0044] Known conditions: the price of natural gas purchased from gas source A is 105.94 $ / 10,000 m3, the price of natural gas purchased from gas source B is 77.69 $ / 10,000 m3, and the minimum amount of natural gas that gas source A can provide is 294,980 m3 / h , the maximum amount is 531,790 m3 / h, the minimum amount of natural gas that gas source B can provide is 436,560 m3 / h, and the maximum amount is 589,950 m3 / h.

[0045] The natural gas company sells natural gas to user D at a price of 264.86$ / 10,000 m3, and sells natural gas to user E at a price of 264.86$ / 10,00...

Abstract

The invention provides a dynamic programming based natural gas production and marketing optimization scheduling model and relates to the production and marketing scheduling technical field. An established dynamic programming model is adopted, a dynamic programming model with the maximum sales revenue of natural gas companies as an objective function according to premise assumptions, parameters are input through programming, the optimal decision sequence of gas distribution and the maximum profit of the natural gas companies are solved by a reversed order recursive method, and accordingly the problems that the solution is performed by a simplex method, the production place of the natural gas is far away from the sales place, the market distribution is dispersed, the requirements of users are fluctuated, and accordingly the non-uniformity on the time and the space is produced and meanwhile the computational overhead of the algorithm is large in the traditional linear programming model are solved. Compared with the prior art, the natural gas production and marketing optimization scheduling model is simple, convenient, rapid and low in cost and the solid technical material foundation is provided for the maximization of the sales revenue of natural gas enterprises.

Description

technical field [0001] The invention relates to the technical field of production and sales scheduling, in particular to a dynamic programming-based optimal scheduling model for natural gas production and sales. Background technique [0002] As a clean, efficient and high-quality energy source, natural gas has developed into the main gas source for urban gas consumption. In the natural gas industry, the main task of natural gas companies is to purchase natural gas from gas fields and then sell natural gas to end users. Among them, due to the different scales and conditions of natural gas production in different gas fields, the prices of natural gas purchased by natural gas companies from different gas fields are also different. In addition, since end users can be divided into two types: interruptible users and non-interruptible users, for different users, the importance of natural gas to their industrial production or daily life is different, so the natural gas prices sold ...
