Abstract

In this case study, an integrated expansion planning of coupled electricity, gas and heat grids as well as coupling technologies of a large German city are presented. Based on a novel integrated planning method and a scenario on generation and load of electricity, gas and heat, the three grids and the coupling technologies are dimensioned for a future supply task. Afterwards, they are analysed regarding their suitability for renewable energy integration. This is conducted for four target images, representing a joint strategic expansion of all infrastructures towards either electrification, hydrogen use, further heat grids or holding to the status quo. To calculate the steady state and time series of the grids and the couplings, a previously published multi-energy flow calculation tool is used.
大型城市电、气、热网耦合综合扩容规划案例研究
本文以德国某大城市为例,介绍了电、气、热网耦合的综合扩容规划及耦合技术。基于一种新颖的综合规划方法和电、气、热发电负荷情景,对未来供电任务的三网及其耦合技术进行了规划。然后,分析了它们对可再生能源整合的适用性。这是针对四个目标图像进行的,代表了所有基础设施的联合战略扩张,包括电气化、氢利用、进一步的热网或保持现状。为了计算网格和耦合的稳态和时间序列,使用了先前发布的多能流计算工具。
