欧盟委员会的气候和能源政策目标是到2050年使欧洲成为第一个气候中立的大陆。对于主要基于可变可再生能源发电的低碳和净中性能源系统，与市场整合、收入蚕食以及风能和太阳能光伏发电的成本回收相关的问题已成为主要问题。传统的优序效应的讨论预计，在一个100%可再生能源的系统中，批发电价将在非常高和非常低的值之间交替。与以往的工作不同，我们提出了一个结构化的和特定技术的分析，在低碳电力市场的价格形成的跨部门需求投标的效果。从一个程式化的市场安排，并通过不断增加它与所有相关技术，我们构建和量化跨部门的需求投标的影响，在未来的欧洲电力市场的跨部门市场建模框架SCOPE SD。作为主要贡献，我们详细解释和证实了新的市场参与者的市场出清效果。因此，我们把一个特别关注的混合供热系统组成的热电联产厂，燃料锅炉，蓄热和电力备份，并得出这些系统的机会成本。此外，我们展示了大规模欧洲净中性能源情景的跨境一体化的影响。最后，市场出清效应的详细信息使我们能够评估未来电力市场上所有主要技术类别的收入。
Climate and energy policy targets of the European Commission aim to make Europe the first climate-neutral continent by 2050. For low-carbon and net-neutral energy systems primarily based on variable renewable power generation, issues related to the market integration, cannibalisation of revenues, and cost recovery of wind and solar photovoltaics have become major concerns. The traditional discussion of the merit-order effect expects wholesale power prices in a system with 100 % renewable energy sources to alternate between very high and very low values. Unlike previous work, we present a structured and technology-specific analysis of the cross-sectoral demand bidding effect for the price formation in low-carbon power markets. Starting from a stylised market arrangement and by successively augmenting it with all relevant technologies, we construct and quantify the cross-sectoral demand bidding effects in future European power markets with the cross-sectoral market modelling framework SCOPE SD. As the main contribution, we explain and substantiate the market clearing effects of new market participants in detail. Hereby, we put a special focus on hybrid heat supply systems consisting of combined heat and power power plant, fuel boiler, thermal storage and electrical back up and derive the opportunity costs of these systems. Furthermore, we show the effects of cross-border integration for a large-scale European net-neutral energy scenario. Finally, the detailed information on market clearing effects allows us to evaluate the resulting revenues of all major technology categories on future electricity markets.
