The research group "Market Integration" deals with the economically optimal integration of renewable energies into the current and future energy system. The core of the research is the development and investigation of future business and market models in the context of regenerative power generation. Computer-aided simulation can be used to map and evaluate various market concepts and framework conditions. In addition to the conventional energy-only markets (EOM), another research focus is on the development of ancillary service markets. These can represent an additional source of revenue for renewable energies and will be decisive for a high proportion of renewable generation in the future.
