Renewable energies thus far have not become a part of a grid restoration process. By building small island grids after a blackout, renewable energies can be integrated into the grid restoration process. Bioenergy‐based power plants have some importance for the supply of such island grids because of their high degree of reliability and controllability. Modern bioenergy plants have electrical loads within a specific kW range, which can be partially used in demand‐side management. A concept for the control structure of off‐grid energy systems with a demand‐side management using a microgrid of a farm supplied by a biogas plant as an example is presented. For the integrability of electrical loads of the biogas plant into the energy management system of the microgrid, an off‐grid control procedure has been designed.
