Aggregation and Smart Grids

The research areas of the Aggregation and Smart Grids group (aka TEAM EnSys - Techno Economic Analysis and Modeling of Energy Systems) are the energy system analysis in the field of smart grids and integration of renewable generation, energy storage and flexibilisation technologies into energy markets in general. The consideration of the economic interactions between the different stakeholders (‘business models’) in this context in particular. That includes optimization and energy system modelling focusing on grid expansion and balancing energy, sustainable energy systems considering hybrid grid structures and security of supply aspects, energy communities, E-Mobility infrastructure and open source modeling.

Fundamental Energy Economics

We focus on general energy economic analyses taking into consideration the supply as well as the demand side and energy policies. On the supply side our major focus is on modelling potentials and scenarios of the mid-term and long-term deployment of renewables. Possible long-term energy storage options such as hydrogen, power-to-gas, methane are other major focuses. On the demand side econometric analyses and scenario modelling are conducted. All these analyses are performed in particular for the electricity and the transport sector, including environmental aspects and energy policy analyses.

Heating/Cooling in integrated energy systems

Our energy economic research focuses on the field of heating/cooling emphasising the role of this sector in an integrated, renewable, efficient energy system. Important applied methods are techno-economic assessment, simulation and optimization models, GIS based modelling, mid- and long-term scenario development techniques and related energy policy analyses.

We cover following exemplary sectors and topics: (1) energy demand and supply in the building stock, (2) district heating and cooling (3) biomass deployment and biomass-to-end-use chains, (4) the coupling between heating/cooling and the other energy sectors, e.g. the role of the sector as a flexibility option and (5) heating/cooling planning and mapping.

Regulation and Energy Markets

The Energy Markets and Regulation Group works on novel concepts of energy market design and further development of network infrastructures, notably in the context of new and renewable energy technology integration and flexibility provision. This addresses several levels of energy transition in the energy supply chain, as there are e.g. wholesale and local market places, increasing sector coupling on transmission and distribution level as well as emergence of new energy technologies and services in the transport sector. Despite strong expertise and focus on electricity markets, research is conducted also in several other energy markets. Moreover, comparative analyses of different market designs and regulatory concepts as well as best-practise identification are important tasks of the group.

Renewable Energy Policy and Markets

The (Renewable) Energy Policies and Market group is conducting analyses on various aspects in the field of energy policies and markets, with a focus on renewable energy technologies and their future prospects within Europe and its neighbors. Modelling is here a key element in the assessments performed, done at energy system level with focus on the impact of policy interventions, the design of instruments / support schemes or aspects of system integration for renewables in Europe’s power system. For these activities we develop our own models (Green-X, HiREPs) or extend the (sector and geographical) coverage of open-source tools (Balmorel). Questions of policy design, market interactions and sustainability aspects (e.g. for bioenergy) are addressed alongside the analyses of broader (techno-economic) impacts.
