基于广义Nash均衡模型的管道运输均衡配置

Balanced distribution of pipeline transportation based on generalized Nash equilibrium model

为了利用有限的管道网络资源来实现天然气的均衡配置,以运营商利润最大化为目标函数,天然气运输量为约束条件,建立并求解基于广义Nash均衡理论的天然气管道运输模型。该模型突破了传统Stackelberg博弈中市场参与者之间明显的行动顺序,突出了运营商之间相互影响、相互合作的关系,实现了天然气资源均衡配置的目的,提高了天然气的利用价值,为天然气上游生产企业、管道运营企业与终端销售企业进行市场判断以及制定生产销售决策提供帮助。数值算例表明:利用广义Nash均衡理论不但可以准确客观地为天然气市场参与者提供定量的决策信息,而且算法简便,实用性强,为我国天然气市场化改革提供了可行方法和理论依据。

In order to realize balanced natural gas distribution by using the limited resources of pipeline networks, a natural gas pipeline transportation model based on the generalized Nash equilibrium theory was established and then solved by taking the operators＇ profit maximization as the objective fimction and the natural gas transport volume as the constraint condition. This model breaks through the obvious action sequence of market participants in the traditional Stackelberg game and highlights the interactive and cooperative relationship between operators, so that natural gas resource is distributed in a balanced pattern and utilized in a better way. It is contributive for the upstream production enterprises, pipeline operators and terminal sales companies to conduct market judgments and make production and marketing decisions. This model is applied to a numerical example. It is shown that the generalized Nash equilibrium theory is convenient and practical and can provide the natural gas market participants with the quantitative decision information accurately and objectively. It provides the feasible method and theoretical basis for the reform of natural gas market in China.
