Abstract
Biomass is becoming a more interesting option to replace conventional fossil fuels for heat energy, electrical energy, and combined heat and power. Biomass energy conversion uses the raw material from agricultural and forest product residues. Due to the regeneration and sustainability of the Bioenergy derived from biomass, it can play an important role in future energy systems. The wide distribution of biomass provides rich sources of raw materials, while the significant development in bioenergy conversion technology improves its competitiveness. There are different ways to convert biomass resources into useful energy. One important type of these conversion processes is the Anaerobic Digestion in which the biomass sources are used to produce biogas. This thesis provides the complete detailed model that fully simulate a biogas-fueled power plant. The proposed model is composed of three individual models represent a biogas reactor, a Microturbine-generation system, and a storage system. Each model can be implemented individually or collectively to simulate the biogas power plant. An adaptive controller is developed to control substrate feed according to the predicted load and to handle the expected changes in electrical load through the speed of microturbine according to the amount of methane stored in the storage system. The whole system (biogas power plant and proposed control) is modeled, implemented, and tested in MATLAB/Simulink environment. The performance of the proposed controller is examined and validated by simulating the biogas plant with and without integrating the Model Predictive Control and H-infinity for different loading conditions. Different operating conditions include normal and transient behavior modes with variable balanced and unbalanced load operation are studied and analyzed.
