Flexible and robust control algorithm for intelligent control of biogas CHP units for stabilizing the power grid

  • The objective of the project presented here is to develop an intelligent control algorithm for an energy system consisting of a biogas CHP (combined heat and power), various storage technologies, such as thermal energy storages (TES) and gas storages, and other renewable energy sources, such as photovoltaics. A corresponding algorithm based on the Monte-Carlo method has already been developed at Reutlingen University for CHP units running on natural gas and for heat pumps. The project presented here concentrates on the further development of this algorithm for application to biogas CP units. In this context, an adequate implementation of the gas storage is of primary importance, as it mainly determines the flexibility of the plant. In the course of the validation of the new optimization algorithm, simulations were carried out based on data from the Lower Lindenhof, an agricultural experimental station of the University of Hohenheim. Both an optimization with regard to onsite electricity utilization and an optimization driven by residual load were investigated. Preliminary results show that the optimization algorithm can improve the operation of the biogas CHP unit depending on the selected target function.
