Abstract

The analysis is based on reviewing the following indicators that are derived from a model-based scenario analysis: CO 2 emissions of electricity generation; regional levels of self-supply with electricity; variable costs of electricity generation; grid congestion and grid expansion needs. The research question is twofold. Firstly, how does the size of decentralised markets affect the indicators mentioned. Secondly, which effects on these indicators can be observed if only power plants of a certain size or technology are allowed to take part in the decentralised markets.The analysis focuses on a system perspective and does not include effects on individual market players. In addition, it focuses on the electricity system with only some interactions with the heating or mobility sectors. The modelling work looks at the effects within the boundaries of a predefined scenario and for two scenario years. Dynamic effects such as a possible effect of decentralised markets on the overall deployment of RES-E technologies or storage systems is therefore not part of the analysis. The results are valid for the German electricity system and cannot necessarily be transferred to other countries or electricity systems with e.g. a weaker electricity grid or less interconnection to neighbouring countries.

德国能源转型不同阶段分散式电力市场的模型评价

这项分析是根据审查下列从基于模型的情景分析得出的指标进行的:发电的二氧化碳排放量;区域电力自给水平;发电可变成本;电网拥塞和电网扩张需求。研究的问题是双重的。首先，去中心化市场的规模如何影响上述指标。其次，如果只允许一定规模或技术的发电厂参与分散市场，可以观察到对这些指标的影响。该分析侧重于系统视角，不包括对单个市场参与者的影响。此外，它侧重于电力系统，仅与供暖或交通部门有一些互动。建模工作着眼于在一个预先确定的情景和两个情景年范围内的影响。因此，诸如分散市场对RES-E技术或存储系统整体部署的可能影响之类的动态影响不在分析范围之内。研究结果对德国电力系统是有效的，不一定适用于其他国家或电网较弱或与邻国互连较少的电力系统。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
