| Abstract | Island systems in developing countries are usually powered by diesel generators and oil-fired power plants due to their reliability and stable energy production. Due to the fluctuating energy production, supply from wind and solar energy alone is not possible. However, by combining several different producers into a hybrid energy system, stable supply is possible. Biogas plants can play a crucial role when compensating the fluctuating energy from photovoltaics with the provision of flexible energy. To compensate for fluctuations from fluctuating producers, and in consumption — appropriate energy storage (biogas storage + battery) or the use of a diesel generator is necessary. Producing biogas according to demand by varying the substrate, the addition period and the addition quantity can minimize the required storage size and use of the diesel generator. To assess the system effects of those hybrid energy systems, we modeled in MATLAB for a fictional village in Limburg, Germany, with industrial loads. This study showed that through demand driven biogas production the energy production of the diesel generator can be reduced by 30 % with levelized costs of Energy provision (LCOE) remaining constant.Furthermore, it was shown that flexible biogas production has a cost-reducing effect when diesel costs rise. With a moderate increase in costs from €2/liter to €6/liter for diesel, the rise in LCOE was reduced by 90% through continuous biogas production and by 96% through flexible biogas production, compared to a diesel generator photovoltaic energy system. |
