Transformation of Energy Systems

To implement an energy supply with a high proportion of renewable sources is considered as a challenge. In our research field "Transformation of Energy Systems" we create, analyse and optimise future scenarios for a sustainable energy supply.

We consider a broad variety of regional, transregional and international demand and supply situations. Using real load and climate information as well as different modelling approaches economically and ecologically optimum supply structures are determined based on transparent input data and different cost assumptions. The optimisation refers to the defined overall system. Its modelling is implemented as realistically as possible or necessary with detailed knowledge of the individual components. In addition to conventional heating and power plants, renewable energy systems and ambient heat, especially storage technologies such as electrolysis, methanation, pumped storage and different types of batteries are included.

We dispose of different models specially developed for the calculation of the electricity sector. With our multi-region model we are able to optimize the regional distribution of supply capacities. Thus central and decentralised structures of energy supply as well as the demand for transmission and storage capacities can be mapped and optimized.

Our "Heat Tool" allows investigating the effectiveness of various measures in the building sector regarding energy consumption and CO2 emissions. These include renovation of differentiated types of buildings, choice of fuel, heating refurbishment or modification of the heating type. Coupled optimization of heat and electricity is an important part of our research and is continually developed.

The focus of the RLI is an implementation-oriented research. The consideration of socioeconomic aspects is therefore a key issue in all topics of the institute. In order to foster regional developments through to decentralized energy supply, the integration and networking of local actors and the development of business models are as well part of the working field of the RLI as the anticipation of future regional developments.
