Abstract

This paper presents a methodology for the creation of a synthetic combined electric and natural gas transmission network, along with representative benchmark results. The systems do not contain actual, confidential network data, but are synthetic, meaning they are built to capture the behavior of a combined network that is geographically constrained. First, natural gas loads are placed in a selected area. Work already done in building synthetic electric grids aids in this process, where the natural gas-powered generators are modeled as loads in the natural gas system. Publicly available data is then used to place the remaining gas loads and the gathering plant. Next, a method is introduced to construct a pipeline network connecting the loads and gathering plant, which acts as the source. The combined electric-gas system is then solved for the nodal pressures, pipeline flow rates, and electric state variables. A 47-node gas test case with 23 loads and 46 pipelines is built and solved in combination with a 173-bus electric system, designed to aid with developing and validating analysis techniques for combined electric-gas systems.

建立综合电力和天然气联合输电网的技术

本文提出了一种建立综合电力和天然气联合输送网络的方法，并给出了具有代表性的基准结果。这些系统不包含实际的、机密的网络数据，而是合成的，这意味着它们是用来捕获地理上受限制的组合网络的行为的。首先，天然气负荷被放置在选定的区域。在构建合成电网方面已经完成的工作有助于这一过程，其中天然气发电机被建模为天然气系统中的负载。然后使用公开可用的数据来放置剩余的气体负荷和收集装置。在此基础上，提出了一种以集输厂为源，连接负荷和集输厂的管网建设方法。然后求解电-气联合系统的节点压力、管道流量和电状态变量。建立了一个包含23个负载和46条管道的47节点气体测试用例，并结合173总线电气系统进行了解决，旨在帮助开发和验证电-气联合系统的分析技术。
