Topic

With the expansion of renewable but volatile power generation from wind and solar energy, the demand for future energy system management is increasing. Especially the security and reliability of electricity supply has to be evaluated with new focuses. The grid stability has to be ensured by controllable energy producers. Apart from solid biomass, biogas is the only energy source that can be stored among the renewable energies. The expansion of the technical and economic potential of controllable power production via biogas plants ensures grid stability in the future.Concepts are generated and simulations are carried out regarding technical modifications for a controllable electricity production via biogas plants. Special focus is on raw biogas storage, the CHP units, the heat supply for internal and external heat demands and the needs of regional distribution grids with a high share of volatile energy producers. The overall efficiency of biogas plants is optimised and a monitoring system and a proactive control unit is implemented in a flexible biogas plant.

Aims & Measures

The aims of the project are:

  • Development of an innovative and proactive control unit for biogas plants
  • Demonstration of a flexible electricity production and simultaneously heat delivery via biogas plants at any time
  • Reduction of grid expansion costs and grid stress by considering the fluctuating electricity production from PV plants while producing electricity via biogas plants
  • Avoidance of grid overload by a flexible, grid-driven operation of a biogas plant at a real existing system (biogas plant Zellerfeld: 1,438 kWel; neighbouring PV plant: 5,000 kWmax)
  • Demonstration and optimisation of a flexible, grid-driven operation of a biogas plant
