摘要： In Germanyare about 8,000 biogas plants in operation, with an installed electrical capacity of 4.5 GW.Within the amendments of the EEG in 2012 and 2014 thelegislative authority promotes a paradigm shift for biogasplants away from a previous and mostly current base load power generation towards a demand driven and flexiblepower generation. This aim requires a fundamental rethinking in how anappropriate concept for biogas plants shouldlook like. One critical issue is how the price patterns at power exchange are in line with the demand patterns forconnected heat sinks. We elaborate some simulations for current-controlled and heat-controlled operation schedulesunder a cogeneration share of 40%. If power generation schedule doesn’t match the heatload profileheat demand canbe ensured by a heat-storage or/ and a peak load boiler, respectively. We figure out the combination of storage andpeak-load in terms ofleast cost intensive. The challenge, to find the most preferable configuration under differentconditions is done by a modelling with discrete input factor variation. Based on these modelling an optimal linkofheat-storage and peak-load boiler is calculated in regardsto investments and operating costs.
