论文摘要
在本文中,我们使用每小时的时间分辨率使用一代扩展计划问题的表述,以研究2040年的不同灵活性来源对碳中含碳中的中欧电力系统的影响(侧重于瑞士)。我们评估了柔性生成,负载转移和进口对现有和新建的单位的投资和进口的作用。我们的结果表明,作为优化的一部分,包括负载转移,可以减少RES和常规技术投资的需求。新建的灵活发电机(燃气轮机)和负载转移的结合增加了模拟电源系统的灵活性,并导致总体最低的系统成本。瑞士与其邻国之间的跨境传输能力降低对国内运营和投资有重大影响,但也可能影响周围的国家。
In this paper, we use a formulation of the generation expansion planning problem with hourly temporal resolution, to investigate the impact of the availability of different sources of flexibility on a carbon-neutral central European power system (with a focus on Switzerland) for the year 2040. We assess the role of flexible generation, load shifting and imports on the investment and operation of existing and newly built units. Our results show that including load shifting as part of the optimization could reduce the need for investments in both RES and conventional technologies. The combination of newly built flexible generators (gas turbines) and load shifting increases the flexibility of the simulated power system and results in the overall lowest system costs. The reduction of cross-border transmission capacity between Switzerland and its neighbors has a significant impact on the domestic operation and investments but could also affect the surrounding countries.
