Abstract:

A mathematical model of decision of optimal scheduling scheme for gas pipeline network is established,it takes minimum annual operating cost of compressor station as objective function after comprehensively considering the resources of gas field,operating parameters of compressor station and work condition of pipeline system.Combing the reproduction strategy of differential evolution algorithm with the cross and variation of genetic algorithm,a new hybrid genetic algorithm is presented to solve the optimal model,and which avoid the premature convergence problem effectively.The analysis of an example in a certain pipeline network system with 12 nodes,11 pipelines and 2 compressor stations demonstrate the effectiveness and applicability of the established model and algorithm.The optimal scheduling scheme can be adapted to daily operation and future retrofit of gas pipeline network.

Key words: natural gas pipeline network, scheduling scheme, genetic algorithm, differential evolution algorithm, optimization
