论文摘要
德国政府最近宣布,到2030年,有80%的电源应来自可再生能源。一项关键任务在于重组传输系统,以便可以从具有良好可再生潜力的站点运输到负载中心。动态线等级(DLR)允许基于现行天气条件而不是保守的不变评级来动态计算传输线的容量,它提供了更好地利用现有网格能力的潜力。在本文中,我们分析了DLR代表德国的详细电力系统模型,包括当今所有额外的高压传输线和变电站的效果。 DLR与风力发电增加之间不断发展的协同作用,在短期内节省约4亿欧元,在2030年的情况下每年节省9亿欧元,每年节省9亿欧元。
The German government recently announced that 80\% of the power supply should come from renewable energy by 2030. One key task lies in reorganizing the transmission system such that power can be transported from sites with good renewable potentials to the load centers. Dynamic Line Rating (DLR), which allows the dynamic calculation of transmission line capacities based on prevailing weather conditions rather than conservative invariant ratings, offers the potential to exploit existing grid capacities better. In this paper, we analyze the effect of DLR on behalf of a detailed power system model of Germany including all of today's extra high voltage transmission lines and substations. The evolving synergies between DLR and an increased wind power generation lead to savings of around 400 million euro per year in the short term and 900 million per year in a scenario for 2030.
