Demand Side Management in Biogas Plants – Dynamic Simulation of the Influence of Time-varying Agitation on Biogas Production Lilli Sophia Röder, Arne Gröngröft, Marcus Grünewald, Julia Riese



In this contribution, monetary benefits that result from demand side management (DSM) integration in biogas digesters are analyzed. A model-based study to describe the influence of an electricity price-adjusted agitation (EPAA) control on biogas production is presented. Three price limits were calculated, which decide on the operation of four different predefined EPAA intervals. Results show that especially at very high and very low electricity prices, DSM strategies in biogas plants can lead to an increase in profit of the plant.
