Multiobjective Gas Distribution Optimization of Natural Gas Pipeline Network Considering User Satisfaction under Shortage Conditions

Abstract

The management of natural gas user daily designation is taken as the background, the characteristics of users are considered, the distribution mode is integrated, and a multiobjective distribution optimization model of natural gas pipeline network under the insufficient condition is constructed. The decision variable is the actual gas distribution volume of users, aiming to minimize the energy consumption of the compressor station and maximize the user satisfaction under multiple physical constraints. Comparing the solution schemes, when the user satisfaction is the same, scheme 4 solved by the optimization method reduces the compressor energy consumption by 8.6% compared with scheme 1 solved by the manual adjustment method. The three optimization solutions are compared and contrasted, the differences in the operation of the pipeline network are analyzed in different optimization solutions, and the changes of the compressor operating parameters with the increase of user satisfaction are expounded. By analyzing the influence of flow distribution among different types of natural gas users on user satisfaction, it is clarified that the two goals of natural gas user satisfaction and pipeline network operation energy consumption are mutually restrictive.
