摘要
目前,天然气资源配置优化主要基于下游用户用气价格,但用气价格高的用户可能存在用气规模小、波动性强、发展潜力低等问题。为此,选取用户用气价格、调峰贡献量、调峰贡献率3个指标,采用数据包络分析法评价用户多维度综合价值,并结合供应、运输及销售环节的约束条件,建立基于用户多维价值的资源配置优化模型。利用该模型对中国中东部地区某研究区域天然气供应情况进行资源配置优化,结果表明:天然气年供应量为465×108m3时,利用基于用户多维价值进行资源配置优化相比基于用户用气价格的配置方案,调峰贡献量提升了3.9×108 m3;相比原方案,调峰贡献量提升了3.4×108m3,销售收益提升了18.28×108元。考虑用户价值进行资源配置有利于挖掘高价值用户,优化天然气供给结构,可为天然气供应资源配置决策与运营水平提升提供理论依据。(图8,表2,参22)
Currently, the optimization of natural gas resource allocation is mainly based on the gas price of downstream users. However, the users paying high gas price may have the problems such as small scale of gas consumption, high volatility and low development potential.Therefore, the multidimensional comprehensive value of users was assessed based on multiple indicators, such as the gas price paid by user and the contribution to peak sheaving, with the data envelope analysis method. Meanwhile, the optimization model of resource allocation based on the multidimensional value of users was established with consideration to the constraint conditions in the links of gas supply,transportation and selling. Then, the resource allocation in the gas supply of a study area in Central and Eastern Region of China was optimized with this model. The results indicate that, when the gas supply is 465×10~8 m~3, the contribution of resource allocation optimization based on the multidimensional value of users to peak sheaving is enhanced by 3.9×10~8 m~3 in comparison to the allocation scheme based on the gas price paid by users. Compared with the original scheme, the contribution to peak sheaving is increased by 3.4×10~8 m~3 and the sales income is increased by 18.28×10~8 yuan. Generally, the resource allocation with consideration to user value is conductive to finding the customers with high value and optimizing the gas supply structure, further providing theoretical basis for the decision-making on resource allocation in gas supply and the enhancement of operation level.(8 Figures, 2 Tables, 22 References)
