Flexibilitätswende – integration of industrial energy systems into regional electricity markets to stabilize the electricity grid
In order to achieve the goals of the German “Energiewende“, the Government forces the expansion of renewable energies. As a result of increasing fluctuating power supply, a lot of electricity is produced without any regulation and without good predictability. Since electricity from renewable energies has priority when it is fed into the grid, the cost-effectiveness of large-scale power plants decreases and in some cases these power plants are shut down by the operators. However, large power plants provide an important contribution to the stability and security of supply in today's electricity grid. In addition, the partially strong spatial separation of renewable power generation and power consumption, for example in the case of wind power, leads to further challenges for the transmission grid.
In order to enable grid stability in Germany, redispatch volumes are increasing. In the liberalized electricity market, however, efficient market mechanisms are needed to preserve grid stability. Therefore, the current energy market design is questionable. It is examined whether central energy markets represent an obstacle to the successful implementation of the German „Energiewende“. Thus, the project "Flexibilitätswende" examines regional electricity markets and their influence on the provision of flexibility by market participants.

The overall objective of the Project "Flexibilitätswende" is to develop methods to model and evaluate regional electricity markets. In order to achieve the objective, new mathematical optimization models are formulated and analyzed. Furthermore, new algorithms for solving optimization problems will be developed, implemented and evaluated based on test data. As a case study, the flexibilization of an industrial energy system in regional electricity markets is examined.
