內容介紹:
China National Petroleum Corporation (CNPC), the largest oil and natural gas producer and supplier in China, plans annual and monthly natural gas production quantities, consumption levels, and transmission amounts. We developed an iterative two-stage convex relaxation approach to solve this challenging task. In the first stage, we estimated the physical parameters for pipelines per a given set of gas flows and gas pressures. In the second stage, we used these parameters to solve for a new set of gas flows and gas pressures. Through numerical tests with the current pipeline network, the proposed solution approach can converge within a 2% relative error within 5 minutes. The solution approach is expected to generate an extra 2.1 billion RMB for CNPC's natural gas usage from 2016 to 2020.
