Abstract

Abstract: Long distance natural gas pipeline is the main facility connecting upstream gas source and downstream users. Compared with the traditional natural gas volume measurement transaction mode, the calorific value measurement transaction can reflect the energy value of natural gas to a greater extent and realize more fair market competition. On the basis of considering the conversion mode of natural gas from volume measurement to calorific value measurement, this paper creatively establishes the pipeline operation optimization model under calorific value measurement mode. The model aims to maximize the economic benefits of pipeline operation, and takes the air source flow, compressor startup number and compressor speed as decision variables. The established optimization model is applied to the Sichuan-east gas transmission pipeline, and the optimization problem is solved by GAMS modeling system and DICOPT solver. The optimization results show that compared with the traditional volume metering model, the sales profit of east Sichuan Gas Transmission Pipeline under the calorific value measurement model is 10.82% higher, and the energy consumption of compressor station is about 3.4% lower. Although the cost of purchasing gas increases, the increase of gas selling income is higher than that of gas purchasing cost.

Key words: natural gas, calorific value measurement, operation optimization, pipeline operation benefit, metering conversion
