The demand-supply balance of electricity systems is fundamentally linked to climate conditions. In light of this, the present study aims to model the effect of climate change on the European electricity system, specifically on its long-term reliability. A resource adequate power system – a system where electricity supply covers demand – is sensitive to generation capacity, demand patterns, and the network structure and capacity. Climate change is foreseen to affect each of these components. In this analysis, we focused on two drivers of power system adequacy: the impact of temperature variations on electricity demand, and of water inflows changes on hydro generation. Using a post-processing approach, based on results found in the literature, the inputs of a large-scale electricity market model covering the European region were modified. The results show that climate change may decrease total LOLE (Loss of Load Expectation) hours in Europe by more than 50%, as demand will largely decrease because of a higher temperatures during winter. We found that the climate change impact on demand tends to decrease LOLE values, while the climate change effects on hydrological conditions tend to increase LOLE values. The study is built on a limited amount of open-source data and can flexibly incorporate various sets of assumptions. Outcomes also show the current difficulties to reliably model the effects of climate change on power system adequacy. Overall, our presented method displays the relevance of climate change effects in electricity network studies.

使用后处理方法将气候变化影响纳入欧洲电力系统的充分性评估

电力系统的供需平衡从根本上与气候条件相关。有鉴于此,本研究旨在模拟气候变化对欧洲电力系统的影响,特别是其长期可靠性。资源充足的电力系统(电力供应满足需求的系统)对发电容量,需求模式以及网络结构和容量敏感。可以预见,气候变化会影响到所有这些因素。在此分析中,我们重点关注电力系统充足性的两个驱动因素:温度变化对电力需求的影响以及进水量变化对水力发电的影响。根据文献中的结果,使用后处理方法,对覆盖欧洲地区的大规模电力市场模型的输入进行了修改。结果表明,气候变化可能会使欧洲的总LOLE(预期负载损失)小时减少50%以上,原因是由于冬季温度升高,需求将大大减少。我们发现,气候变化对需求的影响倾向于降低LOLE值,而气候变化对水文条件的影响则倾向于增加LOLE值。该研究建立在数量有限的开源数据的基础上,可以灵活地整合各种假设。结果还表明,目前难以可靠地模拟气候变化对电力系统充足性的影响。总体而言,我们提出的方法显示了气候变化影响在电网研究中的相关性。由于冬季气温升高,需求将大大减少。我们发现,气候变化对需求的影响倾向于降低LOLE值,而气候变化对水文条件的影响则倾向于增加LOLE值。该研究建立在数量有限的开源数据的基础上,可以灵活地整合各种假设。结果还表明,目前难以可靠地模拟气候变化对电力系统充足性的影响。总体而言,我们提出的方法显示了气候变化影响在电网研究中的相关性。由于冬季气温升高,需求将大大减少。我们发现,气候变化对需求的影响倾向于降低LOLE值,而气候变化对水文条件的影响则倾向于增加LOLE值。该研究建立在数量有限的开源数据的基础上,可以灵活地整合各种假设。结果还表明,目前难以可靠地模拟气候变化对电力系统充足性的影响。总体而言,我们提出的方法显示了气候变化影响在电网研究中的相关性。该研究建立在数量有限的开源数据的基础上,可以灵活地整合各种假设。结果还表明,目前难以可靠地模拟气候变化对电力系统充足性的影响。总体而言,我们提出的方法显示了气候变化影响在电网研究中的相关性。该研究建立在数量有限的开源数据的基础上,可以灵活地整合各种假设。结果还表明,目前难以可靠地模拟气候变化对电力系统充足性的影响。总体而言,我们提出的方法显示了气候变化影响在电网研究中的相关性。
