Hybrid modelling for a biomass-based system for heating and CO2 enrichment
In this work, a biomass-based boiler system with CO2 recovery from flue gases is used. The advantages are twofold: firstly, the cost savings from using chipper fuel as pellets for heating; secondly, from the carbon dioxide stored during combustion being supplied during daylight hours inside the greenhouse for CO2 enrichment. The hybrid system is modelled based on first-principle equations. The resultant model is able to simulate the different operation modes of the system, being highly useful applied with other purposes: (i) at the plant design, (ii) to design traditional or advanced controllers in order to track a desired plant behaviour, and (iii) during the plant scheduling. The model can calculate the optimal configuration of the plant operation modes and references to be tracked in order to minimize the energy consumption. The main contribution of this work is a parametric non-linear dynamical hybrid model for greenhouse CO2 capture and enrichment.
