Natural Gas Pipeline Planning Based On Uncertain Market Conditions

With the continuous deepening of China's energy transition,the natural gas market has entered a period of rapid development,and the construction of natural gas pipelines is also accelerating.By the development of natural gas the uncertain factors in market,is gradually increasing,which also bringing many new challenges to the planning of natural gas pipeline.This paper analyzes the theories and practical experience of researching natural gas consumption forecasting technology at home and abroad,and the new technology and methods of natural gas pipeline planning.To research the new method for selecting the natural gas supply market and the specific planning in the new region.In the Selections of the market for the supply of gas.This paper analyzes and deals with the specific uncertain conditions of the natural gas market,and determines two grey forecasting methods of GM(1,1)and GM(1,N),according to the uncertainty of the data and the uncertainty of the related factors.Through the investigation and analysis of the improved models,using Matlab to achieve the improvement of the two models and establish a combined model,select out the pipeline planning market.In terms of specific pipeline planning,the geographic information system software is used to determine the specific pipeline planning route.According to pipeline's construction cost in different geographical conditions is different,assigning corresponding cost values to geographical conditions,using the analytic hierarchy process to assign different weights for the various thematic factors.Finally establish a comprehensive cost model.Using the cost path analysis function based on Dijkstra's algorithm in ArcGIS,calculate the lowest cumulative cost path.In this paper,by studying market uncertainty conditions and the application of uncertainty theory to optimize the natural gas supplying market,checks and extends current working methods.Using new technology methods for pipeline planning provides a new idea for natural gas pipeline planning.
