Abstract
The northeastern oil pipeline network is the largest regional oil pipeline system in China. As for its operational actuality on the basis of the peak - valley price, the optimization of the daily operation scheme is presented. Virtually, the advantage of the valley price is used to increase the oil throughput rate in the valley period, and accordingly the daily energy consumption cost is lowered. Aiming at the problem the linear programming mathematic model is formulated in this paper. By means of this method, the analysis is carried out for Tieling-Qinhuangdao hot oil pipeline under different daily throughput rates. Some fundamental rules for the optimization of the daily operation scheme based on the peak-valley price are found from the computed results. At the same time, it is shown that the optimal scheme will reduce energy cost of the network to some extent. However, this method is subject to the operational characteristics of the pipeline to some degree. Thus, it is more applicable to the isothermal pipeline than the hot oil pipeline.
