As analysis tool a MATLAB-based model of a distribution grid with multiple storage systems has been implemented. The model is applicable for a wide range of different battery storage systems, various PV-system sizes and diverse grid structures. Different battery management strategies such as fixed power limitation, charging interval timer with regard to typical solar radiation profiles, maximizing self-consumption and maximizing the benefit for the grid have been implemented and analyzed. If the storage is managed properly a relief for the grid can be achieved while at the same time the self-consumption can be retained at nearly the same level as a management strategy purely maximizing the self-consumption.}, language = {en} }
