Abstract

Abstract: In view of the current situation of the multi-source natural gas supply pattern of“one network” in China, the traditional volume measurement and trading system is no longer suitable for the operation and development of China′s natural gas pipeline. The use of energy measurement can better reflect the energy characteristics of natural gas itself and promote the integration and upgrading of the natural gas market. On the basis of considering the implementation scheme of natural gas energy metering system and the demand of non-resident users for natural gas quality, this paper creatively puts forward the operation optimization model of multi-gas source pipe network under the energy measurement system. The model takes the maximization of pipeline operation profit as the goal and the gas supply volume and pressurization mode of the whole line as the decision variables. The model is applied to a long-distance pipeline in China, and the optimal solution of the model is obtained by using GAMS/ANTIGONE solver. The optimization results show that the optimization results under different energy measurement system implementation schemes are better than the actual operation schemes on site, and the maximum operating profit is increased by 32.05%. Among them, the gas purchase cost accounts for the highest proportion in the pipeline operation cost, which is comprehensively affected by the gas price, gas supply volume and calorific value of each gas source; the pipeline transportation cost and compressor station operation cost are indirectly affected by the gas supply volume of each gas source; the higher the calorific value content of natural gas at the demand node is, the higher the gas sales revenue.

Key words: natural gas, energy measurement, operation optimization, pipeline operating profit, multi-gas source pipeline network
