The increasing share of intermittent renewable energy sources (RES) potentially endangers a reliable power system operation. Due to the variability and unpredictability added RES, reserve requirements will increase in future. To counter this, adequate sizing techniques are major importance. While most operators apply simple deterministic or probabilistic models assuming RES forecast errors follow Gaussian distribution, we propose an improved dynamic method using nonparametric distributions...

The European electricity industry, the dominant sector of world's largest cap-and-trade scheme, is one most-studied examples carbon pricing. In particular, numerical models are often used to study uncertain future development prices and emissions. While parameter uncertainty addressed through sensitivity analyses, potential themselves remains unclear from existing single-model studies. This investigates such model-related by running a structured model comparison experiment, which exposes...

The development of European power markets is highly influenced by integrated electricity and heat systems. Therefore, decarbonization policies for the sectors, as well numerical models that are used to guide such policies, should consider cross-sectoral interdependencies need evaluation. Many model-based policy assessments evaluate potential benefits combined power. However, extent benefits, emissions reductions, found in existing studies subject considerable variations. While scenarios...

The expansion of wind and solar energy has so far primarily led to the decarbonization electricity sector. Against this background, power-to-gas (PtG) is seen as a solution supporting other sectors, such heating or transport. As generation mix will transitionally be based on fossil-fired technologies, upcoming integration PtG into markets comes with several challenges. While current debate focuses sustainability criteria support mechanisms, requires further development market design....

A variety of models have emerged in the field energy system analysis to answer a wide range research questions centred around sustainable future for sector. Even designed address similar issues often different focus or modelling approach. Thus, model experiments are vital tool provide an overview and enable decision-makers make meaningful choices. Such comparisons executed based on harmonised data set ensure high degree comparability. In MODEX project cluster, six experiments, including 40...

Future congestion management is one of the major market design issues in European electricity market. In light sharp increase redispatch measures seen within last years, importance an efficient network increases particularly Germany. Against this background, we develop integrated approach to model (re)dispatch for Germany detail while considering interactions with neighbouring countries. Compared 2011, our findings indicate a much more critical situation 2015. We identify increased RES...

For the further development of an integrated European electricity market, congestion management mechanisms are one major market design issues. Against background increasing generation from renewables and resulting congestions, efficient network congestions is gaining importance especially in Germany. Introducing nodal pricing as first best mechanism not considered to be realistic for Germany nearby future. Yet splitting German into several zones will also improve management. A key issue...

Germany’s energy transition is associated with increasing congestion in the electricity transmission grids due to infeed from renewable sources, especially wind turbine installation at periphery coastal areas. Here, regional differences generation and demand lead grid bottlenecks northern southern parts of country, thus leading expansion requirements towards load centers. However, long times for combination rapid renewables amplify congestion. The provision flexibility one way overcome this...

In European power markets, recent regulatory changes impose minimum trading capacities to increase cross-border trade. However, the sweeping definition of margins neglects underlying physical grid constraints, resulting in higher redispatch volumes and costs. This raises questions about efficiency welfare effects whether alternative approaches exist for increasing Against this background, contribution studies impact integrating potential into flow-based market coupling (FBMC). Accordingly,...
