DSM (demand-side management) merits increased attention by power system modelers. Numerical models should incorporate DSM constraints in a complete and consistent way. Otherwise, flawed DSM patterns and distorted conclusions on the system benefits of demand-side management are inevitable....

We examine the role of prosumage of solar electricity, i.e. PV self-generation combined with distributed storage, in the context of the low-carbon energy transformation. First, we devise a qualitative account of arguments in favor of and against prosumage. Second, we give an overview of...

Ausgehend von einem niedrigen Niveau ist die Eigenstromversorgung mit Solarenergie und Batteriespeichern in Deutschland in den letzten Jahren deutlich gewachsen. Diese Entwicklung ging insbesondere auf den gegenläufigen Trend von Haushaltsstrompreisen und Einspeisetarifen sowie eine staatliche...

Starting from a low level, in recent years the battery-supported self-consumption of solar electricity (solar prosumage) has grown significantly in Germany. Its growth is primarily due to the opposing trends in household electricity prices and feed-in tariffs in conjunction with government...

The use of renewable energy sources is a major strategy to mitigate climate change. Yet Sinn (2017) argues that excessive electrical storage requirements limit the further expansion of variable wind and solar energy. We question, and alter, strong implicit assumptions of Sinn’s approach and...

A flexible coupling of power and heat sectors can contribute to both renewable energy integration and decarbonization. We present a literature review of model-based analyses in this field, focusing on residential heating. We compare geographical and temporal research scopes and identify...

Die Umsetzung der Energiewende erfordert einen weiteren starken Ausbau der erneuerbaren Energien in Deutschland. Jedoch werden in der energiepolitischen Debatte immer wieder Zweifel geäußert, ob eine weitgehend auf fluktuierender Wind- und Solarenergie basierende Energieversorgung möglich...

Im Kontext der Energiewende stellt sich die Frage, ob elektrische Speicherheizungen einen Beitrag zur verstärkten Nutzung der fluktuierenden Wind- und Solarenergie und zur Emissionsminderung im Raumwärmebereich leisten können. Im Rahmen eines europäischen Forschungsprojekts wurde am DIW...

Using electricity for heating can contribute to decarbonization and provide flexibility to integrate variable renewable energy. We analyze the case of electric storage heaters in German 2030 scenarios with an open-source electricity sector model. We find that flexible electric heaters generally...

Green hydrogen can help to decarbonize parts of the transportation sector, but its power sector interactions are not well understood so far. It may contribute to integrating variable renewable energy sources if production is sufficiently flexible in time. Using an open-source co-optimization...
