摘要:

欧洲联盟(欧盟)能源系统实现气候中立的雄心勃勃的能源目标提出了在所有能源部门只使用可再生能源的可行性问题。作为欧盟主要工业化国家之一,德国通过了若干气候行动计划,以便在其能源系统中切实执行和最大限度地利用可再生能源。文献回顾显示,在描述一个开放的建模方法,用于分析完全可再生能源和部门耦合的能源系统的综合技术的明显差距。本文概述了一种分析德国100%可再生能源和部门耦合能源系统可行性的方法。基于开放式能源建模框架,开发了一个逐时优化工具“OSeEM-DE”来研究德国的能源系统。模型结果表明,在德国,100%基于可再生能源和部门耦合的电力和建筑供热系统是可行的。投资能力和组件成本取决于开发方案的参数变化。挥发性发电机的年投资成本在176亿至266亿欧元/年之间,热发电机的年投资成本在237亿至288亿欧元/年之间。该模型建议每年至少投资27 - 39亿欧元用于电力和热储存。OSeEM-DE结果与最近的研究比较验证了从模型中计算出的均衡化电力成本(LCOE)值。敏感性分析表明,存储和网格扩展最大限度地提高了系统的灵活性,降低了投资成本。该研究最后展示了该工具如何在欧盟范围内分析不同的能源系统。

英文摘要:

The ambitious energy target to achieve climate-neutrality in the European Union (EU) energy system raises the feasibility question of using only renewables across all energy sectors. As one of the EU's leading industrialized countries, Germany has adopted several climate-action plans for the realistic implementation and maximum utilization of renewable energies in its energy system. The literature review shows a clear gap in comprehensive techniques describing an open modeling approach for analyzing fully renewable and sector-coupled energy systems. This paper outlines a method for analyzing the 100% renewable-based and sector-coupled energy system's feasibility in Germany. Based on the open energy modeling framework, an hourly optimization tool 'OSeEM-DE' is developed to investigate the German energy system. The model results show that a 100% renewable-based and sector-coupled system for electricity and building heat is feasible in Germany. The investment capacities and component costs depend on the parametric variations of the developed scenarios. The annual investment costs vary between 17.6 and 26.6 bn Euro/yr for volatile generators and between 23.7 and 28.8 bn Euro/yr for heat generators. The model suggests an investment of a minimum of 2.7-3.9 bn Euro/yr for electricity and heat storage. Comparison of OSeEM-DE results with recent studies validates the percentage-wise energy mix composition and the calculated Levelized Cost of Electricity (LCOE) values from the model. Sensitivity analyses indicate that storage and grid expansion maximize the system's flexibility and decrease the investment cost. The study concludes by showing how the tool can analyze different energy systems in the EU context.
