I examine the effects of increasing amounts of fluctuating renewable energy on residual load, which is defined as the difference between actual power demand and the feed-in of non-dispatchable and inflexible generators. I draw on policy-relevant scenarios for Germany and make use of extensive...

We examine the effects of future renewable expansion in Germany on residual load and renewable surplus generation for policy-relevant scenarios for 2022, 2032 and 2050. We also determine the storage capacities required for taking up renewable surpluses for varying levels of accepted curtailment....

We analyze future scenarios of integrating electric vehicles (EV) into the German power system, drawing on different assumptions on the charging mode. We use a numerical dispatch model with a unit-commitment formulation which minimizes dispatch costs over a full year. While the overall energy...

Achieving the objectives of the German governments 2010 Energy Concept and the accelerated phase-out of nuclear energy will require significant investment in restructuring energy supply. In particular, this includes investment in installations for the use of renewable energy sources in the power...

The Energiewende in Germany aims at increasing the share of fluctuating renewable energy drastically. With this, new challenges for the electricity system arise. Different types of storage and other flexibility options are available to cope with these challenges. This paper discusses different...

The German Renewable Energy Sources Act (EEG) has proven to be an effective instrument in promoting electricity from renewable resources, and the same basic structure has been adopted by a large number of other countries. The support provided for in the EEG consists particularly of a guaranteed...
