Optimization of Stand-alone HRES Energy System with Biogas-Plant with Flexible-Demand Driven Biogas Production

Short Introductive summary

Stand-alone grids are often supplied by diesel Engines or oil power plants with high emissions. With the use of HRES Energy systems with high renewable energy production content, pollution can be minimized. In this energy system, the use of a diesel engine is still necessary to balance the fluctuating energy production of wind and solar power plants. With the use of biogas plants for balancing fluctuating wind and solar power, the use of diesel engines can be reduced. This study presents a method for the optimization of the size of the components of the biogas based HRES Energy system. The method based on the mathematic modelling and simulation of the components in Matlab. The biogas process is modelled with the AM2 biogas model with acid inhibition and hydrolysis kinetics by Arzate [2]. For optimization, particle swarm optimization is employed. For the biomass substrate are used gras and corn silage. The result shows that in HRES standalone energy systems, in comparison with HRES with continuous biogas production, through the flexible production of biogas, the production of energy from diesel engines and with that the CO2 emissions are reduced.
