Abstract

The socially desired withdrawal from nuclear power in Germany is an opportunity for the agricultural sector to gain new markets by the marketing of energy. Dairy farms can produce more energy than consumed by itself through photovoltaic on the roof, wind turbines, geothermal energy and the use of manure in biogas plants. By automated dairy cow stables with milking (AMS), feeding (AFS) and cleaning robots the energy consumption of the stable has become steady and is much more flexible as in classical systems. The target of the designed energy management system is to steer production and consumption in a manner which guarantees that the energy consumption of the dairy farm is secured and also energy marketing is optimized. The welfare of the dairy cows has also to be considered to assure a high milk production. Therefore the energy management system has to be regulated by the animal parameters. By recording of animal parameters (milk production, feed intake, motion profile⋯), stable data (workload, charging cycles, operating specifications⋯) and climate data (temperature, solar irradiation, wind⋯) a short-, medium- and long-term energy profile can be calculated for the future. Within the scope of these profiles consumers in the barn can be switched on and off at short notice in order to be able to provide electricity for the public grid which is subsequently offset by capacity from the public grid. The dairy farms acts as regional grid compensation. The first practical results of the project and the basic structure of the planning algorithm for the energy profiles will be explained.
