A Formal Modeling Framework for Anaerobic Digestion Systems
The complexity of modeling the anaerobic digestion
process meets the difficulty to describe and analyze
them mathematically. In this paper, a simplified mathematical
model for anaerobic digestion process of organic matter,
in a continuous stirred tank reactor is proposed. With the
aim of upgrading the produced biogas and integrate biogas
plants in a virtual power plant, new control inputs reflecting
addition of stimulating substrates (acetate and bicarbonate) are
added. Based on two step (acedogenesis-methanogenesis) mass
balance non linear model, a step-by-step model parameter’s
identification procedure is presented in the first step, then in
the second step, the yield coefficients and the microbial growth
rates are estimated when the later is assumed to be unknown
