DISTRICT – Region: System Development & Market Integration Heat & Power


Especially at distribution network level, a close interconnection in utilization and generation of electricity and heat will lead to new opportunities for complementary use and for securing the stability of the electricity grid. In an energy system with high shares of fluctuating renewable energies, these tasks play a decisive role.
The model DISTRICT examines the systemic opportunities of the electricity and heat cogeneration at distribution network level. The main questions which are answered by the model are the following: How does a future cost-optimized energy system including the annual development path look? Which flexibility options will be used in this minimum-cost energy system? What role do energetic building refurbishments play in an optimized system?
